Background-Postinfarction ventricular septal defect carries a grim prognosis. Surgical repair offers reasonable outcomes in patients who survive a healing phase. Percutaneous device implantation represents a potentially attractive early alternative. Methods and Results-Postinfarction ventricular septal defect closure was attempted in 53 patients from 11 centers (1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012); aged 72±11 years; 42% female). Nineteen percent had previous surgical closure. Myocardial infarction was anterior (66%) or inferior (34%). Time from myocardial infarction to closure procedure was 13 (first and third quartiles, 5-54) days. Devices were successfully implanted in 89% of patients. Major immediate complications included procedural death (3.8%) and emergency cardiac surgery (7.5%). Immediate shunt reduction was graded as complete (23%), partial (62%), or none (15%). Median length of stay after the procedure was 5.0 (2.0-9.0) days. Fifty-eight percent survived to discharge and were followed up for 395 (63-1522) days, during which time 4 additional patients died (7.5%).
