Case of rheumatic mitral stenosis with bilateral coronary artery fistula to pulmonary artery: A rare entity.

J Cardiovasc Thorac Res 2021 30;13(2):176-178. Epub 2021 Jan 30.

Department of Cardiovascular and Thoracic Surgery, Gujarat, India.

Coronary to pulmonary artery fistula is a rare form of congenital coronary artery anomaly. Majority of coronary arteriovenous fistula detected incidentally on coronary angiography. Although, most of these patients are asymptomatic, larger fistulae can produce symptoms of heart failure. Here we present a rare case of 61-year-old female who presented primarily for mitral valve replacement for severe mitral stenosis. On screening angiography, there were two fistula arising from both right and left coronary artery and draining in to the main pulmonary artery. The patient was operated and mitral valve replacement with closure of the fistula. Patient had an uneventful post-operative period and was discharged on 7 the post-operative day.

Total arterial multivessels minimal invasive direct coronary artery bypass grafting via left minithoracotomy.

Gen Thorac Cardiovasc Surg 2021 Jan 25;69(1):8-13. Epub 2020 Jun 25.

Department of Cardio Thoracic and Vascular Surgery, U.N.Mehta Institute of Cardiology and Research Center, Civil Hospital Campus, Asarwa, Ahmedabad, 380016, Gujarat, India.

Background: Minimal Invasive Direct Coronary Artery Bypass Surgery (MIDCAB) is becoming popular and an important armamentarium for cardiac surgeons. We aimed to evaluate the result of MIDCAB total arterial revascularization.

Methods: We have evaluated 216 patients who underwent MIDCAB multivessel total arterial revascularization through a left anterolateral mini thoracotomy. LIMA harvested in every patient, RIMA or radial artery used as second conduit. LIMA-RIMA Y or LIMA-RADIAL Y was made to accomplish multivessels total arterial revascularization. Post-operative graft patency was evaluated in all patients by CT coronary angiography at 6 months following discharge.

Results: Mean age of patients was 52.5 ± 9.8 years. Average number of anastomosis performed were 2.34 ± 0.75. Multivessels total arterial CABG was accomplished in all individuals. There was no mortality or deep wound infection. Re-exploration was done in two patients for bleeding. In one patient emergency CPB was required. Average ICU and hospital stay was 1.52 ± 0.77 and 4.92 ± 1.46 days, respectively. Patients were mobilized earlier due to less pain. Wound healing of anterolateral thoracotomy was faster. In the follow up CT angiography 100% of the LIMA grafts were patent.

Conclusions: Multivessels total arterial MIDCAB can be accomplished safely in selected individuals. RIMA can be harvested in long standing diabetic patients with no concern for sternal wound healing. MIDCAB patients experience better cosmetics and early return to daily activities.

Does addition of bi-directional cavo-pulmonary shunt to tricuspid repair in advanced cases of Ebstein anomaly result in better outcomes?

Gen Thorac Cardiovasc Surg 2020 Dec 20;68(12):1388-1396. Epub 2020 May 20.

Department of Cardiac Anesthesia, U. N. Mehta Institute of Cardiology and Research Center, Ahmedabad, India.

Objectives: Ebstein anomaly can be managed by single ventricular, bi-ventricular and one and a half ventricular repairs. We present midterm results of Comprehensive Tricuspid Valve repair (CTVR) with bi-directional cavo-pulmonary shunt (BCPS).

Methods: In this prospective observational study (Jan2012-July2018), 69 patients underwent surgery for Ebstein anomaly. In Group I (n = 48; 69.6%), all patients got CTVR and a BCPS (one and a half ventricle repair). Group II (n = 15; 21.8%) consisted of a similar repair without BCPS (bi-ventricle repair). All patients were echocardiographed at six monthly intervals.

Results: Median age of the cohort was 17 years (range 1-68). 12 (17.4%) patients were Carpentier type B, 51 (73.9%) were type C and 6 (8.7%) were type D. There were two early mortalities (2.89%). At a mean follow up of 3.2 ± 1.2 years, there were no late deaths and one delayed repair-failure in each group. Group I had significantly lower mean TR grade (1.2 ± 0.4vs1.6 ± 0.5, p = 0.03) as compared to Group II without a significant difference in the mean gradients (1.5 ± 0.5vs1.6 ± 0.6, p = 0.4). Mean indexed TAPSE (15.0 ± 6.7vs.16.6 ± 5.6 mm/m, p = 0.21), NYHA class (1.2 ± 0.4vs1.3 ± 0.4) and six-minute walk distance (506 vs 507 m, p = 0.7) was similar in both groups.

Conclusion: One and a half ventricle repair of Ebstein anomaly gives a more functionally competent, non-stenotic and durable tricuspid valve as compared to a two-ventricle repair. BCPS doesn't result in facial swelling or AV malformations. Preload reduction by BCPS may allow the myopathic ventricle to remodel.

Ebstein's Anomaly: "The One and a Half Ventricle Heart".

Braz J Cardiovasc Surg 2018 Jul-Aug;33(4):353-361

Department of Research, U. N. Mehta Institute of Cardiology and Research Centre (affiliated to BJ medical college, Ahmedabad), Gujarat, India.

Objective: Ebstein's anomaly remains a relatively ignored disease. Lying in the 'No Man's land' between congenital and valve surgeons, it largely remains inadequately studied. We report our short-term results of treating it as a 'one and a half ventricle heart' and propose that the true tricuspid annulus (TTA) 'Z' score be used as an objective criterion for estimation of 'functional' right ventricle (RV).

Methods: 22 consecutive patients undergoing surgery for Ebstein's anomaly were studied. Echocardiography was performed to assess the type and severity of the disease, tricuspid annular dimension and its 'Z' score. Patients were operated by a modification of the cone repair, with addition of annuloplasty, bidirectional cavopulmonary shunt (BCPS) and right reduction atrioplasty to provide a comprehensive repair. TTA 'Z' score was correlated later with postplication indexed residual RV volume.

Results: There was one (4.5%) early and no late postoperative death. There was a significant reduction in tricuspid regurgitation grading (3.40±0.65 to 1.22±0.42, P<0.001). Residual RV volume reduced to 71.96±3.8% of the expected volume and there was a significant negative correlation (rho -0.83) between TTA 'Z' score and indexed residual RV volume. During the follow-up of 20.54±7.62 months, the functional class improved from 2.59±0.7 to 1.34±0.52 (P<0.001).

Conclusion: In Ebstein's anomaly, a higher TTA 'Z' score correlates with a lower postplication indexed residual RV volume. Hence, a complete trileaflet repair with offloading of RV by BCPS (when the TTA 'Z' score is >2) is recommended. The short-term outcomes of our technique are promising.
