Abstract

Objectives: Ventricular septal rupture (VSR) is a rare but feared complication after myocardial infarction (MI). The objective of this study was to investigate the effects of thrombolytic therapy on the patterns of VSR following MI.

Methods: 30 consecutive patients admitted to a single tertiary level cardiac hospital with a diagnosis of acute MI and developed VSR in the hospital were included. The effect on thrombolytic therapy on the formation of VSR and its clinical outcome was studied.

Results: Out of 30 patients, 15 patients received thrombolytic therapy.10 received early (<12h) and 5 received late (>12h). The median time to post MI VSR formation was significantly shorter in thrombolysis group compared to non thrombolysis group at 1 vs 3 days(p=0.026). The median time for VSR formation was shorter in early thrombolysis group compared to late thrombolysis group at 1 vs 3 days (p=0.022). There was no difference between late and no thrombolytic therapy (3 vs 3 days, p=0.672). There was no significant difference in the mortality between thrombolytic and no thrombolytic therapy (p=0.690). Patients treated medically had a significant higher mortality compared to patients treated surgically (p=0.005).

Conclusion: Thrombolytic therapy results in an earlier presentation of VSR after MI. This earlier presentation may be due to reduction in the number of patients developing late VSR after thrombolytic therapy, while the number of patients developing an early VSR remaining unaffected. Despite improvements in medical therapy and percutaneous and surgical techniques, mortality with this complication remains extremely high.
