Abstract

Objective: Ventricular Septal Rupture (VSR) following Acute Myocardial Infarction (AMI) is a fatal mechanical complication with high incidence of mortality. The aim of this study is to explore the clinical outcomes and to identify the factors related to early mortality in patients with VSR after AMI. Materials and Methods: This was a retrospective study and we collected clinical data of 21 adult patients with VSR following AMI from April 2012 and October 2020 who got admitted at our tertiary care centre. The patients were classified into two groups. The first group consisted of patients who died within two weeks from the diagnosis of VSR following AMI and the second group comprised of patients who survived more than two weeks after VSR. Results: A total of 21 patients (mean age of 66.19±9.47 years) were enrolled in this study. The most common MI was Anterior MI (71.4%) and the location of VSR was predominantly in the anterior and apical septum (76.2%). The overall early mortality was 85.9% (n=18). 80.95% (n=17) of patients died within two weeks of diagnosis of AMI. Of the 4 patients who survived more than two weeks, three patients survived. The operative mortality in our study was 47%. Conclusion: The prognosis for VSR in AMI remains poor. Renal failure is accompanied with high rate of early mortality in patients with VSR complicating AMI. History of smoking is associated with poor outcome.
