Introduction: The immediate surgical repair of a ventricular septal defect complicating acute myocardial infarction (VSD post-AMI) is associated with high mortality. The percutaneous closure device is safe and effective in patients with post-infarction VSD; we report the immediate and long term results in the use of the Amplatzer device in the primary closure of post infarction VSD. Material and methods: From June 2006 to January 2014, 17 patients carriers of post-infarction VSD underwent percutaneous Amplatzer closure with a mean age 66.8 ± 5.5, 82.4% in cardiogenic shock (CS), 35.3% were thrombolyzed (TT) in window, the average time to percutaneous closure of VSD 8.7 ± 5.8 days. Results: With a current monitoring of 13.25 ± 12.6 months procedural success were in 100% shunt (QP:QS) was reduced from 2.9 to 1.5 ± 0.40 ± 0.95 L/min p = 0.0001, 12 patients (70.6%) undergoing PTCA the culprit vessel post-closure of the VSD. Global mortality at 30 days was 52.9%, being higher in patients with CS versus 64.3 versus 0% no-CS p = 0.043 OR 2.8 (CI 95% 1.38-5.6). Conclusion: The primary closure of postinfarction VSD is a very promising technique that can be performed with a high success rate and minimal complications and may be taken as an alternative to surgery. However despite being a less invasive technique remains high mortality very evident in patients in CS.
