ABSTRACT

Background: Ventricular septal rupture is devastating complication of acute myocardial ischemia. The majority of times, single vessel disease is culprit of presentation. Some time multi-vessel disease can also be present, so main objective of this study is to see if addition of coronary artery bypass surgery to culprits vessel and to other coronary arteries add benefit to patient by measuring the operative mortality.

Methodology: A retrospective analysis of 31 patients who underwent isolated VSR repair or VSR plus CABG was performed from January 2010 to December 2018 at CPE Institute of Cardiology Multan. SPSS version 16 was utilized to analyze the baseline characteristics and operative mortality of VSR repair surgery and p-value of 0.05 or less was consider as significant.

Results: Total 18 patients underwent CABG plus VSR repair and 13 patient underwent isolated VSR surgery. Operative mortality in VSR repair was 25.8%, 6 out of 8 patients who died underwent CABG vs 12 out of 25 who survived underwent CABG with p-value of 0.26. This revealed that coronary artery bypass do not impact operative mortality in VSR repair.

Conclusion: Addition of coronary artery bypass surgery to VSR repair do not add any benefit with regards to operative mortality.
