Abstract
Introduction: Post-myocardial infarction ventricular septal rupture (post-MI-VSR) is a dreaded complication with high mortality. There is a varied survival pattern among patients who have undergone surgical repair. Aim: To assess the survival rates in patients who underwent surgical repair for post-MI-VSR in a single centre. Materials and Methods: A retrospective observational study was conducted in the Department of Cardiothoracic Surgery at Jayadeva Institute of Cardiovascular Sciences and Research, Bangalore, Karnataka, India. The patient records from January 2005 to December 2020, who underwent surgical repair of postMI-VSR, were reviewed. The perioperative variables, mortality, and survival data were analysed. Kaplan-Meier analysis was performed to assess the survival time. Results: The mean age of the studied patients was 58.4±7.5 years. A total of 73 patients underwent surgery for post-MIVSR. A total of 40 (55.80%) were males and 33 (45.20%) were females. Overall, 36 (49.32%) patients had diabetes, and 27 (36.99%) had hypertension. Anterior Myocardial Infarction (MI) (n=56, 76.71%) was the most common location of MI. The mean Cardiopulmonary Bypass (CPB) and clamp times were 144.05±59.09 and 105.38±38.34 minutes, respectively. The mean survival time was 2619.564 days {95% Confidence Interval (CI) 2105.936 to 3133.192}. Conclusions: As revascularisation confers a significant survival advantage, VSR repair with concomitant Coronary Artery Bypass Graft (CABG) appears beneficial.
