Characteristics of a large-scale cohort with accessory pathway(s): A cross-sectional retrospective study highlighting over a twenty-year experience.

Turk Kardiyol Dern Ars 2021 Sep;49(6):456-462

Department of Cardiology, Liv Hospital, Ankara, Turkey.

Objective: Catheter ablation following electrophysiologic study (EPS) is the mainstay of diagnosis and treatment for patients with atrioventricular reentrant tachycardia (AVRT), demonstrating excellent long-term outcome and a low rate of complications. In this study, our aim was to assess our experience in patients with accessory pathway (AP) and to compare our data with the literature.

Methods: We included 1,437 patients who were diagnosed and treated for AP in our hospital between 1998 and 2020. The demographic data of all the patients, AP location, and periprocedural results were recorded.

Results: Of the 1,437 patients, 1,299 (90.4%) were men; and the mean age of the population was 26.67 years. The location of 1,418 APs were along the left free wall (647 [45.6%] patients), in the posteroseptal region (366 [25.3%] patients), in the anteroseptal region (290 [20.4%] patients), and along the right free wall (115 [8.1%] patients). The ratio of the second AP existence was 3.0% and AVNRT co-existence was 2.0%. A total of 55 (3.8%) patients had recurrent sessions for relapse. Our center's total success rate was 95.5%, and total complication rate was 0.26%.

Conclusion: According to our retrospective analysis, EPS is a highly functional tool in the diagnosis and management of arrhythmias such as AVRT for high-risk patient groups like military personnel with the aim of risk stratification and medical management.

Radiofrequency catheter ablation of patients with permanent junctional reciprocating tachycardia and long-term follow-up results.

J Interv Card Electrophysiol 2021 Sep 2. Epub 2021 Sep 2.

Department of Cardiology, Liv Hospital, Ankara, Turkey.

Background: Permanent junctional reciprocating tachycardia (PJRT) is an infrequent form of atrioventricular re-entrant tachycardia. We report the clinical and electrophysiological properties of PJRT and outcomes of radiofrequency catheter ablation (RCA) in a large group of patients.

Methods: We included 62 patients with the diagnosis of PJRT. Radiofrequency catheter ablation was performed in all.

Results: Location of accessory pathway was right posteroseptal in 37 (59,7%) cases, right midseptal in 3 (4,8%), left posterior in 7 (11,3%), left lateral in 5 (8,1%), left posterolateral in 3 (4,8%), left anterolateral in 2 (3,2%), left posteroseptal in 2 (3,2%), middle cardiac vein in 2 (3,2%), and left coronary cusp in 1 (1,6%). Single procedure success rate was 90.3%. None of patients had recurrence during follow-up after repeat ablations. Overall long-term success rate was 98.4%. Left ventricular systolic function recovered in all patients with tachycardia-induced cardiomyopathy (TIC).

Conclusion: Retrograde decremental accessory pathways are mainly located in posteroseptal region. Radiofrequency catheter ablation is a safe and effective approach in patients with PJRT.

The association between thrombotic and inflammatory biomarkers and lower-extremity peripheral artery disease.

Int Wound J 2020 Oct 22;17(5):1346-1355. Epub 2020 May 22.

Department of Cardiology, TOBB Economics and Technology University Medical School, Ankara, Turkey.

Lower-extremity peripheral artery disease (LEAD) is associated with increased rates of mortality and morbidity. The aim of this study was to evaluate the associations among inflammatory and thrombotic markers and lower-extremity peripheral disease. A total of 280 patients were enrolled in this study. Of these patients, 152 patients had LEAD on peripheral angiography that was performed because of suspected lower-extremity peripheral disease based on history, physical examination, and non-invasive tests. The control group consisted of 128 patients without LEAD on peripheral angiography. Patients with LEAD were classified according to trans-atlantic inter-society consensus (TASC) II classification. Subsequently, patients in TASC A to B were defined as having mild to moderate peripheral artery disease, and those in TASC C to D were defined as having advanced peripheral artery disease. Thrombotic and inflammatory markers, such as the neutrophil-to-lymphocyte ratio (NLR), the high-sensitivity C (hs-C) reactive protein level, the monocyte-to-high-density lipoprotein-cholesterol ratio, the fibrinogen to albumin ratio (FAR), and whole-blood viscosity at high shear rate (HSR) and low shear rate (LSR), were evaluated in this population. The NLR, the monocyte-to-high-density lipoprotein-cholesterol ratio, the FAR, and whole-blood viscosity, both at a LSR and a HSR, were significantly higher in patients with lower-extremity peripheral disease compared with patients without lower-extremity peripheral disease. We determined that lower-extremity peripheral disease severity was correlated with the NLR, monocyte-to-high-density lipoprotein-cholesterol ratio, FAR, whole-blood viscosity at LSR, and whole-blood viscosity at HSR (r = 0.719, P = .004; r = 0.25, P = .008; r = 0.691, P = .002; r = 0.546, P < .001; and r = 0.448, P = .001, respectively). However hs-C reactive protein levels were similar between patients with or without LEAD (2.47 ± 1.32 1.61 ± 0.91 P = .685). In addition, there was no correlation between the severity of LEAD and hs-C reactive levels. In this study, we determined that the levels of inflammatory and thrombotic biomarkers are elevated in peripheral artery disease, and these levels predict disease severity.

The association between the fibrinogen-to-albumin ratio and coronary artery disease severity in patients with stable coronary artery disease.

Coron Artery Dis 2020 09;31(6):512-517

Department of Cardiology, TOBB Economics and Technology University Medical School.

Objective: Fibrinogen-to-albumin ratio (FAR) is an inexpensive and easily measurable novel inflammatory index that has been found to be associated with atherosclerosis. In this study, we aimed to investigate the association between the FAR and coronary artery disease (CAD) severity in patients with stable CAD.

Methods: In total, 356 consecutive patients with CAD were classified into three groups, those with a low Synergy between percutaneous coronary intervention and the Taxus and Cardiac Surgery Study (SYNTAX) score (≤22), those with an intermediate SYNTAX score (23≥ SYNTAX score ≤32) and those with a high SYNTAX score (>32).

Results: We determined that there were significant differences in the mean age (P < 0.001), male gender (P = 0.008), serum fibrinogen (P = 0.03), low-density lipoprotein cholesterol (P < 0.001) and FAR (P < 0.001) among the SYNTAX score groups. A strong positive correlation was detected between FAR and SYNTAX score (r = 0.899; P < 0.001), and the cutoff level of FAR for high SYNTAX score was 82 (sensitivity of 82%, specificity of 88.3% and an area under the curve of 0.826).

Conclusion: The novel inflammatory index, FAR, is significantly associated with the severity of CAD in patients with stable CAD.

Blood Group Types O and Non-O Are Associated With Coronary Collateral Circulation Development.

Clin Appl Thromb Hemost 2020 Jan-Dec;26:1076029619900544

Department of Cardiology, TOBB Economics and Technology University Medical School, Ankara, Turkey.

Blood group types are associated with coronary artery disease. However, data are scarce about the impact of blood group types on coronary collateral circulation. In this study, we aimed to investigate the relationship between the blood group types and coronary collateral circulation. Two hundred and twelve patients who underwent coronary angiography in our department and had a stenosis of ≥ 90% in at least one major epicardial vessel were included in our study. Collateral degree was graded according to Rentrop-Cohen classification. After grading, patients were divided into poor coronary collateral circulation (Rentrop grade 0 and 1) and good coronary collateral circulation (Rentrop 2 and 3) groups. The ABO blood type of all participants was determined. The incidence rates of O blood group type were significantly higher in the good coronary collateral group compared to the poor collateral group (37.9% vs 17.1%, < .001). The O type blood group was an independent predictor of good coronary collateral circulation (odds ratio = 1.83, 95% confidence interval = 1.56-6.18, = .015). Coronary collateral circulation is associated with blood group types. The O blood group predicts good coronary collateral development among patients with coronary artery disease.

Arq Bras Cardiol 2019 12;113(6):1129-1137

University of Health Science, Turkiye Yuksek Ihtisas Training and Research Hospital - Cardiology, Ankara - Turkey.

Background: Left ventricular aneurysm (LVA) is an important complication of acute myocardial infarction. In this study, we investigated the role of N- Terminal pro B type natriuretic peptide level to predict the LVA development after acute ST-segment elevation myocardial infarction (STEMI).

Methods: We prospectively enrolled 1519 consecutive patients with STEMI. Patients were divided into two groups according to LVA development within the six months after index myocardial infarction. Patients with or without LVAs were examined to determine if a significant relationship existed between the baseline N- Terminal pro B type natriuretic peptide values and clinical characteristics. A p-value < 0.05 was considered statistically significant.

Results: LVA was detected in 157 patients (10.3%). The baseline N- Terminal pro- B type natriuretic peptide level was significantly higher in patients who developed LVA after acute MI (523.5 ± 231.1 pg/mL vs. 192.3 ± 176.6 pg/mL, respectively, p < 0.001). Independent predictors of LVA formation after acute myocardial infarction was age > 65 y, smoking, Killip class > 2, previous coronary artery bypass graft, post-myocardial infarction heart failure, left ventricular ejection fraction < 50%, failure of reperfusion, no-reflow phenomenon, peak troponin I and CK-MB and NT-pro BNP > 400 pg/mL at admission.

Conclusions: Our findings indicate that plasma N- Terminal pro B type natriuretic peptide level at admission among other variables provides valuable predictive information regarding the development of LVA after acute STEMI.

Platelet to lymphocyte ratio predicts all-cause mortality in patients with carotid arterial disease.

Rom J Intern Med 2019 Jun;57(2):159-165

TOBB Economy and Technology University Cardiology Department, Ankara, Turkey.

Background: Platelet to lymphocyte ratio (PLR) has been demonstrated as a risk and prognostic marker in many of cardiovascular diseases. A relationship between PLR and severity of carotid stenosis has been shown. The aim of our study was to investigate the relationship between PLR and all cause mortality in patients with carotid arterial disease.

Methods: This retrospective study included 146 patients who had been performed selective carotid angiography. Carotid stenosis were graded by the North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria. Platelet to lymphocyte ratio was calculated as the ratio of platelets to lymphocytes. The end point of the study was all-cause mortality.

Results: During median follow-up of 16 months (0-65 months) 15 (10.3%) patients suffered all-cause mortality. 50 patients (34.2%) underwent carotid endarterectomy and 69 patients (47.3%) had non-carotid cardiac surgery. 38 patients (26.02%) had cerebrovascular events (stroke/transient ischemic attack) at admission. NASCET grades were not different between survivors and non-survivors. Non-survivors had significantly lower hemoglobin (Hb) levels (12.7 ± 1.6 g/dL vs. 13.7 ± 1.7 g/dL, p = 0.031) and they were older than survivors (74.2 ± 8.4 years vs. 68.6 ± 8.5 years, p = 0.029). Non-survivors had significantly higher PLR values compared with survivors (190.3 ± 85.6 and 126.8 ± 53.8, p = 0.017). In multivariate analysis, only PLR predicted all-cause mortality in patients with carotid artery stenosis.

Conclusion: In our study, higher PLR was associated with increased all-cause mortality.

Comparison of quantitative and qualitative coronary angiography: computer versus the eye.

Cardiovasc J Afr 2018 Sep/Oct;29(5):278-282

Department of Cardiology, Dumlupinar University, Kutahya Evliya Celebi Education and Research Hospital, Dumlupinar, Turkey.

Objective: Since visual estimation of the extent of vessel stenosis may vary between operators, we aimed in this study to investigate both inter-observer variability and consistency between the estimation of an operator and quantitative coronary analysis (QCA) measurements.

Methods: A total of 147 elective percutaneous coronary intervention patients with 155 lesions between them were consecutively enrolled in the study. These patients were evaluated for visual estimation of lesion severity by three operators. The lesions were also evaluated with QCA by an operator who was blinded to the visual assessments. Reference diameter, minimal lumen diameter, percentage diameter of stenosis, percentage area of stenosis and diameter of lesion length from the proximal lesion-free segment to the distal lesion-free segment were calculated using a computerised QCA software program.

Results: There was a moderate degree of concordance in the categories 70-89% (κ: 0.406) and 90-99% (κ: 0.5813), whereas in the categories < 50% and 50-69% there was a low degree of concordance between the visual operators (κ: 0.323 and κ: 0.261, respectively). There was a low to moderate grade of concordance between visual estimation and percentage area of stenosis by QCA (κ: 0.30) but there was no concordance between visual estimation and percentage diameter of stenosis by QCA (κ: -0.061). Also, there was a statistically significant difference between QCA parameters of percentage diameter of stenosis and percentage area of stenosis (58.4 ± 14.5 vs 80.6 ± 11.2 %, p < 0.001).

Conclusions: Visual estimation may overestimate a coronary lesion and may lead to unnecessary coronary intervention. There was low concordance in the categories < 50% and 50-69% between the visual operators. Percentage area of stenosis by QCA had a low to moderate grade of concordance with visual estimation. Percentage area of stenosis by QCA more closely reflected the visual estimation of lesion severity than percentage diameter of stenosis.

One-year results of primary stenting for TASC II D lesions of the superficial femoral and popliteal arteries.

Acta Cardiol 2017 Feb;72(1):36-40

b Department of Cardiology , Dumlupinar University , Kutahya , Turkey.

Objective This study aimed to evaluate the safety and the efficacy of primary stenting to treat Trans-Atlantic Inter-Society Consensus II (TASC) D femoropopliteal lesions. Background Advances in wire, balloon and stent design have been reported to improve the durability of stenting of longer femoropopliteal lesions. Methods A total of 57 limbs of 53 patients with Rutherford stage 3 to 6 due to TASC D femoropopliteal lesions were treated with a self-expanding nitinol stent in a prospective, single-centre, observational study. End points of interest included primary and secondary patency, target lesion revascularization, in-stent restenosis, major adverse cardiovascular events, Rutherford class improvement and change in walking capacity at 1 year. Results A total of 53 patients (57 lesions) were treated with a self-expanding nitinol stent and final procedural success was 91.2%. The median length of the treated segment was 330 ± 96 mm. The median stented segment was 366 ± 71 mm and the mean number of the stents was 2.1 ± 0.9. At 1 year, primary and secondary patency rates were 63.9% and 82.1%, respectively. Major adverse cardiovascular events occurred in 11 patients (22.9%), and[[strike_start]] [[strike_end]]significant benefits were observed in Rutherford class and walking distance (both P < 0.001). Conclusions Primary implantation of self-expanding nitinol stents for the treatment of TASC D femoropopliteal lesions appears to be safe and effective, especially in patients who have multiple co-morbidities and a high risk for surgical bypass. The risk of restenosis was higher when long stenting was extended to the popliteal artery.

The effects of air pollution and weather conditions on the incidence of acute myocardial infarction.

Am J Emerg Med 2016 Mar 4;34(3):449-54. Epub 2015 Dec 4.

Dumlupinar University Kutahya Evliya Celebi Education and Research Hospital, Cardiology.

Objective: In this retrospective study, we investigated the association between air pollution and weather conditions with the incidence of acute myocardial infarction (AMI) in the city of Kutahya.

Methods: A total of 402 patients who were admitted with acute ST segment elevation MI and non-ST segment elevation MI were included in the study in 1 year. Daily maximum, minimum, and mean ambient temperature and mean barometric pressure data were obtained from the Kutahya Meteorology Department. Daily air pollution data were obtained from the Web site of National Air Quality Observation Network (http://www.havaizleme.gov.tr).

Results: Increase in ambient air temperature in the day of MI and 2 days before the day of MI according to their control days was correlated with increase in number of MI cases. When we grouped the patients according to ages as 30-54, 55-65, and >65 years, we found that there was a relation between sulfur dioxide (SO2) and the occurrence of AMI for the age group of 30-54 for the same day (D0) (P<.017). The number of AMIs was the lowest in fall season, whereas the number of AMIs was the highest in winter season.

Conclusion: There was no statistically significant association between the particulates with diameter b=10 μm, SO2 concentrations, air pressure, and the risk of AMI, but there was statistically significant relation between occurrence of MI and SO2 for the patients under age of 55 years. The number of AMIs was the lowest in fall season, whereas the number of AMIs was the highest in winter season.

The usefulness of plateletcrit to predict cardiac syndrome X in patients with normal coronary angiogram.

Postepy Kardiol Interwencyjnej 2015 28;11(3):197-201. Epub 2015 Sep 28.

Department of Cardiology, School of Medicine, Dumlupinar University, Kutahya, Turkey.

Introduction: Cardiac syndrome X (CSX) is a clinical entity defined as the triad of typical angina pectoris on exercise, electrocardiographic or metabolic findings of ischemia and normal epicardial coronary arteries. Platelets, whose amount in the blood is indicated with plateletcrit (PCT), play an important role in inflammatory and thrombotic processes and the physiopathology of cardiovascular events.

Aim: To investigate the association between cardiac syndrome X and PCT and platelet count.

Material And Methods: A total of 113 patients with normal coronary angiogram were included in the study. Fifty patients with typical chest pain and evidence of myocardial ischemia in non-invasive tests formed the CSX patient group. The control group consisted of 63 age- and gender-matched patients with normal coronary arteries but without angina.

Results: The mean PCT value of the CSX group was significantly higher than that of the control group (0.22 ±0.06 vs. 0.19 ±0.04; respectively, p=0.03). Higher PCT was found to be associated with the presence of CSX in patients with normal coronary arteries by multivariate logistic regression analysis.

Conclusions: We suggest that high PCT may predict the presence of cardiac syndrome X in patients with normal coronary arteries. The value of PCT appears additive to conventional expensive methods commonly used in CSX prediction.

Time-to-reperfusion in STEMI undergoing interhospital transfer using smartphone and WhatsApp messenger.

Am J Emerg Med 2015 Oct 31;33(10):1382-4. Epub 2015 Jul 31.

Department of Cardiology, Dumlupinar University, Kutahya, Turkey.

Objective: The objective of this study is to assess the efficacy of WhatsApp application as a communication method among the emergency physician (EP) in a rural hospital without percutaneous coronary intervention (PCI) capability and the interventional cardiologist at a tertiary PCI center.

Background: Current guidelines recommend that patients with ST-segment elevation myocardial infarction (STEMI) receive primary PCI within 90 minutes. This door-to-balloon (D2B) time has been difficult to achieve in rural STEMI.

Methods And Results: We evaluated 108 patients with STEMI in a rural hospital with emergency department but without PCI capability to determine the impact of WhatsApp triage and activation of the cardiac catheterization laboratory on D2B time. The images were obtained from cases of suspected STEMI using the smartphones by the EP and were sent to the interventional cardiologist via the WhatsApp application (group 1, n=53). The control group included concurrently treated patients with STEMI during the same period but not receiving triage (group 2, n=55). The D2B time was significantly shorter in the intervention group (109±31 vs 130±46 minutes, P<.001) with significant reduction in false STEMI rate as well.

Conclusion: This study demonstrates that use of WhatsApp triage with activation of the cardiac catheterization laboratory was associated with shorter D2B time and results in a greater proportion of patients achieving guideline recommendations. The method is cheap, quick, and easy to operate.

Possible role for cryoballoon ablation of right atrial appendage tachycardia when conventional ablation fails.

Tex Heart Inst J 2015 Jun 1;42(3):289-92. Epub 2015 Jun 1.

Focal atrial tachycardia arising from the right atrial appendage usually responds well to radiofrequency ablation; however, successful ablation in this anatomic region can be challenging. Surgical excision of the right atrial appendage has sometimes been necessary to eliminate the tachycardia and prevent or reverse the resultant cardiomyopathy. We report the case of a 48-year-old man who had right atrial appendage tachycardia resistant to multiple attempts at ablation with use of conventional radiofrequency energy guided by means of a 3-dimensional mapping system. The condition led to cardiomyopathy in 3 months. The arrhythmia was successfully ablated with use of a 28-mm cryoballoon catheter that had originally been developed for catheter ablation of paroxysmal atrial fibrillation. To our knowledge, this is the first report of cryoballoon ablation without isolation of the right atrial appendage. It might also be an alternative to epicardial ablation or surgery when refractory atrial tachycardia originates from the right atrial appendage.

Introduction: Radiofrequency (RF) ablation of the slow pathway for treatment of atrioventricular nodal reentrant tachycardia (AVNRT) is conventionally performed during sinus rhythm.

Aim: To evaluate the clinical and electrophysiological features and the short- and long-term results of slow pathway RF ablation during ongoing AVNRT.

Material And Methods: A total of 282 consecutive patients with AVNRT undergoing RF catheter ablation were analysed. Patients whose tachycardia episodes could not be controlled during RF energy application and who underwent slow pathway ablation or modification during ongoing tachycardia formed the study group (group 1, n = 16) and those ablated during sinus rhythm formed the control group (group 2, n = 266).

Results: Of the clinical characteristics, only the frequency of tachycardia attacks was higher in group 1 (3.3 ±1.2 vs. 2.1 ±0.9 attacks/month, p < 0.001). Among the baseline electrophysiological measurements, the echo zone lasted significantly longer in group 1 than in group 2 (78 ±25 ms vs. 47 ±18 ms; p < 0.001). The immediate procedural success rate was 100% in both groups. There were no significant differences between groups regarding the mean number of radiofrequency energy applications (5.2 ±4.2 vs. 5.8 ±3.9), total procedure times (42.4 ±30.5 min vs. 40.2 ±29.4 min) and fluoroscopy times (11.4 ±8.5 min vs. 12.2 ±9.3 min) (p > 0.050 for all). All patients were followed-up for 29 ±7 months; only 2 patients (< 1%) in group 2 recurred (p > 0.050). No permanent atrioventricular block was observed.

Conclusions: The RF catheter ablation or modification of the slow pathway during ongoing AVNRT is feasible with acceptable short- and long-term efficacy and safety. However, this approach needs to be clarified with large-scale studies.

Relationship between platelet-to-lymphocyte ratio and coronary slow flow.

Anatol J Cardiol 2015 May 8;15(5):391-5. Epub 2014 Apr 8.

Department of Cardiology, Faculty of Medicine, Dumlupınar University; Kütahya-Turkey.

Objective: The coronary slow flow phenomenon (CSFP), which is characterized by delayed distal vessel opacification in the absence of significant epicardial coronary disease, is an angiographic finding. The aim of this study is to investigate the association between platelet-to-lymphocyte ratio (PLR) and coronary blood flow rate.

Methods: This is a retrospective observational study. It was based on two medical centers. A total of 197 patients undergoing coronary angiography were included in the study, 95 of whom were patients with coronary slow flow without stenosis in coronary angiography and 102 of whom had normal coronary arteries and normal flow.

Results: The PLR was higher in the coronary slow flow group compared with the control groups (p=0.001). In the correlation analysis, PLR showed a significant correlation with left anterior descending (LAD) artery thrombolysis in myocardial infarction (TIMI) frame count. After multiple logistic regression, high levels of PLR were independently associated with coronary slow flow, together with hemoglobin.

Conclusion: PLR was higher in patients with CSFP, and we also showed that PLR was significantly and independently associated with CSFP.
