RESUMEN
INTRODUCTION: Ventricular septal rupture (VSR) is a serious mechanical complication after acute coronary syndrome and is related to high mortality. Even with advances in the management of acute myocardial infarction (AMI) such as reperfusion therapies, complication rates are still high. During quarantine, patients presenting mechanical complications after AMI have increased in our institution. METHODS: From a retrospective database analysis in our institution between the years 2004 and 2020, we identified 37 cases of VSR after AMI. Four chronic cases were excluded from our analysis. The primary endpoint was to identify baseline characteristics that increased 30-day mortality. RESULTS: Among 33 acute cases of VSR, 24 cases were submitted to surgery. The 30-day mortality of the operated patients was 45.8%. From 2004 to 2019 our average number of operations of VSR was 1.9 cases/year with an increase to 4 cases/year in 2020. Diabetes mellitus, age, cardiogenic shock, and use of intra-aortic balloon pump were associated with significantly increased mortality using logistic regression. CONCLUSION: We reported an increased number of mechanical complication cases from April to September 2020, compared to our historical records. Despite therapeutic advances, mortality rates remain high. Although the number of cases is small to conclude that the pandemic was responsible for this augmentation, we believe that it is related to the decreased number of patients seeking medical assistance.
