J Clin Med 2021 Feb 17;10(4). Epub 2021 Feb 17.

Division of Cardiovascular Medicine, Hôpital Civil, Strasbourg University Hospital, 67000 Strasbourg, France.

Background and purpose-current guidelines recommend the use of transesophageal echocardiography (TEE) in relation to cardio-embolic sources of stroke. Methods-by using an hospital-based cohort, we retrospectively analyzed consecutive patients with acute ischemic stroke (AIS), acute hemorrhagic stroke (AHS) and transient ischemic attack (TIA) who were admitted in Strasbourg Stroke Center, France between November 2017 to December 2018. TEE reports were screened for detection of potential cardiac sources of embolism and the subsequent change in medical management. We performed univariate and multivariate analyses to identify predictors of relevant TEE findings. Results-out of the 990 patients admitted with confirmed stroke, 432 patients (42.6%) underwent TEE. Patients with TEE were younger (62.8 ± 14.8 vs. 73.8, < 0.001), presented less comorbidities and lower stroke severity assessed by lower NIHSS (2 IQR (0-4) vs. 3 IQR (0-10), < 0.01) and Modified (1 IQR (0-1) vs. 1 (0-3), < 0.01). A total of 227 examinations (52.5%) demonstrated abnormal findings considered as potential cardiac sources of embolism and 31 examinations (7.1%) were followed by subsequent change in medical management. Age (HR: 0.948, 95% CI 0.923 to 0.974; < 0.001), previous AIS (HR: 3.542, 95% CI 1.290 to 9.722; = 0.01), previous TIA (HR: 7.830, CI 95% 2214 to 27,689; = 0.001) and superficial middle cerebral artery territory infarction (HR: 2.774, CI 95% 1.168-6.589; = 0.021) were strong independent predictors with change in medical management following TEE. Conclusions-additional TEE changed the medical course of stroke patients in 7.1% in a French high-volume stroke unit.

Background Electrocardiographic strain pattern (ESP) has recently been associated with increased adverse outcome in aortic stenosis and after surgical aortic valve replacement. Our study sought to determine the impact and incremental value of ESP pattern in predicting adverse outcome after transcatheter aortic valve replacement. Methods and Results A total of 585 patients with severe aortic stenosis (mean age, 83±7 years; men, 39.8%) were enrolled for transcatheter aortic valve replacement from November 2012 to May 2018. ESP was defined as ≥1-mm concave down-sloping ST-segment depression and asymmetrical T-wave inversion in the lateral leads. The primary end points of the study were all-cause mortality, rehospitalization for heart failure, myocardial infarction, and stroke. A total of 178 (30.4%) patients were excluded because of left bundle-branch block (n=103) or right bundle-branch block (n=75). Among the 407 remaining patients, 106 had ESP (26.04%). At a median follow-up of 20.00 months (11.70-29.42 months), no impact of electric strain on overall and cardiac death could be established. By contrast, incidence of rehospitalization for heart failure was significantly higher (33/106 [31.1%] versus 33/301 [11%]; <0.001) in patients with ESP. By multivariate analyses, ESP remained a strong predictor of rehospitalization for heart failure (hazard ratio, 2.75 [95% CI, 1.61-4.67]; <0.001). Conclusions In patients with aortic stenosis who were eligible for transcatheter aortic valve replacement, ESP is frequent and associated with an increased risk of postinterventional heart failure regardless of preoperative left ventricular hypertrophy. ESP represents an easy, objective, reliable, and low-cost tool to identify patients who may benefit from intensified postinterventional follow-up.

Effective Orifice Area of Balloon-Expandable and Self-Expandable Transcatheter Aortic Valve Prostheses: An Echo Doppler Comparative Study.

J Clin Med 2021 Jan 7;10(2). Epub 2021 Jan 7.

Pôle d'Activité Médico-Chirurgicale Cardiovasculaire, Hôpitaux Universitaires de Strasbourg, 67000 Strasbourg, France.

Published data on the size-specific effective orifice area (EOA) of transcatheter heart valves (THVs) remain scarce. Here, we sought to investigate the intra-individual changes in EOA and mean transvalvular aortic gradient (MG) of the Sapien 3 (S3), CoreValve (CV), and Evolut R (EVR) prostheses both at short-term and at 1-year follow-up. The study sample consisted of 260 consecutive patients with severe aortic stenosis who underwent transcatheter aortic valve implantation (TAVI). EOAs and MGs were measured with Doppler echocardiography for the following prostheses: S3 23 mm ( = 74; 28.5%), S3 26 mm ( = 67; 25.8%), S3 29 mm ( = 20; 7.7%), CV 23 mm ( = 2; 0.8%), CV 26 mm ( = 15; 5.8%), CV 29 mm ( = 24; 9.2%), CV 31 mm ( = 9; 3.5%), EVR 26 mm ( = 22; 8.5%), and EVR 29 mm ( = 27; 10.4%). Values were obtained at discharge, 1 month, 6 months, and 1 year from implantation. At discharge, EOAs were larger and MGs lower for larger-size prostheses, regardless of being balloon-expandable or self-expandable. In patients with small aortic annulus size, the hemodynamic performances of CV and EVR prostheses were superior to those of S3. However, we did not observe significant differences in terms of all-cause mortality according to THV type or size. Both balloon-expandable and self-expandable new-generation THVs show excellent hemodynamic performances without evidence of very early valve degeneration.

Acute Myopericarditis in a Patient With Mild SARS-CoV-2 Respiratory Infection.

CJC Open 2020 Sep 20;2(5):435-437. Epub 2020 Jun 20.

Radiology Cardiovascular Imaging, University Hospitals of Strasbourg, Strasbourg, France.

Herein is presented a case of a 71-year-old woman with mild SARS-CoV-2 respiratory infection who experienced acute myopericarditis diagnosed using clinical, biological, and electrocardiogram data and cardiac magnetic resonance imaging. The presented case highlights the risk of cardiac involvement, even in the absence of severe respiratory COVID-19 infection. The mechanisms involved in acute myocardial injury in SARS-CoV-2 infection are not well known and requires further studies to determine whether it is related to direct myocardial damage by the virus or to a systemic condition.

Bilateral Acute Cardioembolic Limb Ischemia After Coronavirus Disease 2019 Pneumonia in a Lung Transplant Recipient: A Case Report.

Transplant Proc 2020 Nov 30;52(9):2715-2718. Epub 2020 Jun 30.

Pneumology Unit, Strasbourg Lung Transplant Program, Hôpitaux Universitaires de Strasbourg, Strasbourg, France.

Very few cases of lung transplant patients affected by coronavirus disease 2019 (COVID-19) have been reported to date. A 31-year-old patient who underwent bilateral lung transplantation for cystic fibrosis in 2012 was admitted for severe acute lower limb pain. He had a confirmed exposure to COVID-19 and a 3-week history of upper respiratory tract infection. Whole-body computed tomography (CT) angiography revealed an occlusion of the 2 common femoral arteries. CT angiography detected an intracardiac thrombus in the left ventricle. Chest CT angiography showed ground-glass opacities consistent with COVID-19. A bilateral femoral surgical embolectomy using Fogarty catheter was successfully performed. Specific reverse transcription polymerase chain reaction for severe acute respiratory syndrome coronavirus 2 performed on an extracted thrombus was negative, but IgM antibodies specific for COVID-19 were detected. Cardiac magnetic resonance imaging demonstrated a subendocardial and almost transmural late gadolinium enhancement in the mid and distal inferolateral and inferior wall segments, consistent with a nonrecent myocardial infarction and an apical centimetric thrombus adjacent to the lesion. Thrombophilia laboratory tests found the presence of a positive lupus anticoagulant. Treatment with low-molecular-weight heparin and aspirin was prescribed. On day 13, the patient was discharged from the hospital. This case underlines the need to be vigilant with respect to the thrombotic complications of COVID-19 and raises the issue of thrombosis prevention in COVID-19 patients.

Reactive oxygen species (ROS) are central bioenergetic markers linked to aortic stenosis (AS) development and severity. We sought to evaluate the time course and impact of ROS assessed by plasmatic superoxide anion (SA) among patients undergoing transcatheter aortic valve replacement (TAVR). Among 106 patients, SA significantly decreased after TAVR. Dropped values were measured 10 min after TAVR (0.590 ± 0.181 0.648 ± 0.193;  < 0.001) and persistent at 3 days (0.611 ± 0.0.228 0.646 ± 0.199;  = 0.033) and 30 days follow-up (0.572 ± 0.207 0.639 ± 0.199;  = 0.005). Increased baseline SA (>75 percentile) was continuously associated with higher postprocedural SA values 10 min after valve expansion ( < 0.001), at 3 days ( < 0.001) and 30 days ( < 0.001). Higher baseline SA was linked to higher inflammatory response assessed by higher C-reactive protein values at day 1 and day 3. The composite endpoint of all-cause mortality and/or stroke and/or pacemaker implantation and/or significant paravalvular aortic regurgitation ≥mild at 30 days did not differ significantly according to SA baseline values ( = 0.055). This is the first report identifying a decrease in oxidative stress level after TAVR. Our observation leads to the hypothesis that oxidative stress biomarkers may survive the journey from bench to bedside in AS and TAVR and become new biomarkers with both diagnostic and prognostic values. 31, 420-426.

Primary Hemostatic Disorders and Late Major Bleeding After Transcatheter Aortic Valve Replacement.

J Am Coll Cardiol 2018 10;72(18):2139-2148

Université de Strasbourg, Pôle d'Activité Médico-Chirurgicale Cardio-Vasculaire, Nouvel Hôpital Civil, Centre Hospitalier Universitaire, Strasbourg, France; UMR 1260 INSERM Nanomédecine Régénérative, Université de Strasbourg, Strasbourg, France. Electronic address:

Background: Periprocedural and late (>30 days) bleedings represent major complications after transcatheter aortic valve replacement and have been identified as potential areas for improved patient care.

Objectives: The authors sought to evaluate the impact of ongoing primary hemostasis disorders on late major/life-threatening bleeding complications (MLBCs).

Methods: Bleedings were assessed according to the VARC-2 (Valve Academic Research Consortium-2) criteria. Closure time of adenosine diphosphate (CT-ADP), a surrogate marker of high molecular weight von Willebrand multimers proteolysis was assessed 24 h after the procedure. Ongoing primary hemostasis disorder was defined by a CT-ADP >180 s.

Results: Among 372 patients who survived at 30 days, MLBCs occurred in 42 patients (11.3%) at a median follow-up of 383 days (interquartile range: 188 to 574 days). MLBCs were mainly of gastrointestinal origin (42.8%) and were associated with increased overall mortality (hazard ratio [HR]: 5.66; 95% confidence interval [CI]: 3.10 to 10.31; p < 0.001) and cardiac mortality (HR: 11.62; 95% CI: 4.59 to 29.37; p < 0.001). A 2.5-fold elevation of MLBCs could be evidenced in patients with a CT-ADP > 180 s (27.4% vs. 11.5%; p < 0.001). Multivariate regression analysis identified paravalvular leak (PVL) (HR: 6.31; 95% CI: 3.43 to 11.60; p < 0.0001) and CT-ADP > 180 s (HR: 3.08; 95% CI: 1.62 to 5.81; p = 0.0005) as predictor of MLBCs.

Conclusions: MLBCs after transcatheter aortic valve replacement are frequent and associated with an increased morbidity and mortality. PVL and CT-ADP >180 s were identified as strong predictors for MLBCs. These findings strongly suggest that persistent HMW defects contribute to enhanced bleeding risk in patients with residual PVL.

Background: Out-of-hospital cardiac arrest (OHCA) remains a major public health issue. Emergency coronary angiography and percutaneous coronary intervention might improve survival, especially when cardiac arrest is caused by acute myocardial infarction (AMI). However, identifying patients with AMI after OHCA remains challenging. The aim of this study was to determine the clinical and ECG criteria in OHCA that may help to identify better the patients with AMI.

Methods: Consecutive OHCA patients who underwent emergency coronary angiography in our centre between 2009 and 2013 were included in this retrospective single-centre observational study.

Results: A total of 177 patients with complete datasets were included. Significant coronary artery disease was found in 71% of the patients, and 43% presented with AMI. The independent predictors of AMI were ST elevation in any lead including aVR (odds ratio (OR) 18.06; 95% confidence interval (CI) 6.6-49.38), chest pain before cardiac arrest (OR 4.05; 95% CI 1.55-10.54) and an initial shockable rhythm (OR 2.99; 95% CI 1.34-6.45). An additive score that included these three predictors yielded a sensitivity and a specificity for detecting AMI of 93% and 63%, respectively.

Conclusions: These data suggest that fewer than half of patients with OHCA undergoing emergency coronary angiography present with AMI. The identification of OHCA patients with AMI might be improved by a simple score using post-resuscitation ECG and simple clinical criteria.
