Percutaneous Transcatheter Closure of Post-infarction Ventricular Septal Defect: An Alternative to Surgical...

Post-infarction ventricular septal defect is a mechanical complication of acute MI. The incidence of this complication is low in the primary percutaneous coronary intervention era. However, the associated mortality is very high at 94% with medical management alone. Open surgical repair or percutaneous transcatheter closure still has an in-hospital mortality >40%. Retrospective comparisons between both closure methods are limited by observation and selection bias. This review addresses the assessment and optimisation of patients prior to repair, the optimal timing of repair, and the limitations in current data. The review considers techniques for percutaneous closure, and finally considers the path that future research should take to improve outcomes for patients.
