An Overview of First 100 Cardiac Surgery Cases at a Newly Developed Satellite Center in Sukkur, Pakistan.

Introduction The aim of this research is to evaluate the in-hospital and early outcomes of the first 100 adult cardiac surgeries performed at a newly developed satellite center in Sukkur, Pakistan. Methods This is an audit of the first 100 adult cardiac surgeries performed at a newly developed satellite center of the National Institute of Cardiovascular Diseases (NICVD) at Sukkur, Pakistan, from March 2018 to November 2018 with 12 months of post-operative follow-up. Patients were offered off-pump coronary artery bypass (OPCAB), on-pump coronary artery bypass (ONCAB), mitral valve replacement (MVR), aortic valve replacement (AVR), minimally invasive cardiac surgery (MICS), and congenital adult congenital heart disease (ACHD) procedures by expert faculty of NICVD with a minimum of five years of post-fellowship experience. Results The mean age was 47.11 ± 14.6 years, with a male predominance of 77%. Hypertension and smoking were the most common risk factors that were observed in 32% and 33%, respectively, followed by diabetes and dyslipidemia with a frequency of 20% and 9%, respectively. The mean EuroSCORE (European System for Cardiac Operative Risk Evaluation) II for this patient cohort was 1.165 ± 0.50, with a maximum score of 2.3 in one patient. Out of 100 procedures, 51 were ONCAB, 19 were OPCAB, 16 were MVR, three were AVR, nine were ACHD, and two were MICS. Survival status post-operative as well as after one year was 100%. The frequency of post-operative bleeding was 7%, mean post-operative mechanical ventilation time was 213 ± 273 hours, and in-hospital stay was 5.41 ± 0.165 days. Lost to follow-up at one year was 4% (four). During the follow-up assessment, 39.5% of the patients had complained of mild-to-moderate intensity retrosternal pain and 4.2% had superficial surgical site infection of the sternal wound. A significant improvement in functional class was observed in 38.5% of patients, whereas 4.2% (four) had a significant drop in functional class post-operatively. Conclusion Providing tertiary care and early cardiac surgical facility to the people of Sukkur at their doorstep, in a newly developed satellite center, has resulted in improved outcomes, early quality treatment facility, and avoidance of long travel time.

Combined Degenerative Mitral Valve and Coronary Surgery: Early Outcomes and 10-Year Survival.

BACKGROUND: This study investigated the impact of combined degenerative mitral valve (DMV) and coronary artery bypass grafting (CABG+DMV) surgery vs DMV surgery only on in-hospital health outcome and 10-year survival. METHODS: We identified 745 patients with DMV disease. Of these, 186 (24.9%) were affected also by coronary disease and underwent combined DMV+CABG. They were compared with the remaining 559 patients receiving DMV-only surgery in in-hospital and 1-, 5-, and 10-year survival. We evaluated a short-term composite outcome of hospital mortality, acute kidney injury, cerebrovascular events, and low cardiac output requiring postoperative use of intraaortic balloon pump. In addition, we assessed mitral valve repair rates over time and their correlation with long-term survival. To minimize bias, we conducted a propensity score-matching analysis. RESULTS: DMV+CABG surgery was associated with a similar incidence of the composite end point compared with DMV-only surgery in the unmatched analysis (6.5% vs 5.4%, P = .71) and matched analysis (7.5% vs 8.2%, P = .82). The 10-year survival was 70.5% vs 68.6% (P = .07) for the unmatched analysis and 64.6% vs 62.5% (P = .9) for the matched analysis, DMV+CABG vs DMV-only, respectively. Mitral valve repair had a beneficial effect on short-term outcomes and long-term mortality rates, regardless the presence of concomitant coronary surgery. CONCLUSIONS: Combined DMV+CABG surgery is a very effective surgical treatment with high mitral valve repair rate. Early in-hospital outcome and long-term survival are comparable with DMV-only surgery. In these combined procedures, mitral valve repair is associated with better long-term survival.

Early health outcome and 10-year survival in patients undergoing redo coronary surgery with or without cardiopulmonary bypass: a propensity score-matched analysis.

OBJECTIVES: To investigate the in-hospital health outcome and 10-year survival in patients undergoing redo coronary surgery with (redo-CABG) or without (redo-OPCAB) cardiopulmonary bypass. METHODS: A total of 349 redo coronary surgery patients were identified from our registry. Of these, 143 redo-OPCAB patients (40.97%) were compared with 206 redo-CABG patients. To minimize the bias, we also conducted propensity score matching. In Matched Analysis A, 111 redo-OPCAB patients with any type of primary cardiac operation were compared with 111 redo-CABG cases. In Matched Analysis B, 84 redo-OPCAB patients with isolated coronary surgery as their primary operation were compared with 84 redo-CABG patients. We assessed for all 3 analyses a composite of in-hospital mortality, acute kidney injury, stroke and severe low cardiac output requiring intra-aortic balloon pump. In addition, we assessed 1-, 5-, and 10-year survival. RESULTS: In the unmatched analysis, redo-CABG was associated with higher usage of intra-aortic balloon pump (10 vs 3%, P = 0.01) and composite compared with redo-OPCAB (25 vs 16%, P = 0.06) and similar 10-year survival (67.2 vs 68.5%, log-rank test: P = 0.78). Matched Analysis A showed similar rates of composite (15 vs 21%, P = 0.25) and 10-year survival (65.1 vs 60.8%, log-rank test: P = 0.5). Matched Analysis B showed reduction of the composite (19 vs 8%, P = 0.04), less in-hospital mortality (5 vs 0%, P = 0.13), 4.5 times less need for intra-aortic balloon pump (2 vs 11%, P = 0.02) favouring redo-OPCAB and a similar 10-year survival (71.6 vs 71.7%, log-rank test: P = 0.61). CONCLUSIONS: Redo-OPCAB surgery is feasible, safe and effective with improved in-hospital outcome and similar 10-year survival compared to redo-CABG.
