Spontaneous closure of ventricular septal defect complicated with acute myocardial infarction.

ABSTRACT

A 79-year-old man was followed in our hospital for 4 years following primary percutaneous coronary intervention at another hospital to deploy two stents at the left anterior descending coronary artery for acute myocardial infarction (AMI). At the first visit in our hospital, echocardiography revealed a small ventricular septal defect (VSD, 0.8 to 1.0 cm) in the apicoseptal wall with an aneurysm that was probably the result of the AMI. There was no hemodynamic decompensation, and because the patient refused surgical correction we instead placed him under close follow-up observation in the outpatient clinic. A second follow-up echocardiography 6 months later still revealed a VSD. However, after 3 years the VSD murmur was no longer audible and follow-up echocardiography showed the defect to be nearly closed.
