Post myocardial infarction ventricular septal defect

Post-surgical and post-myocardial infarction ventricular septal defect... 

The vast majority of ventricular septal defects (VSD) are congenital. Acquired VSDs are almost always a consequence of septal rupture following myocardial infarction, traumatic VSDs as a consequence of sharp or blunt chest trauma are exceptionally rare. Typically the post myocardial infarction ventricular septal defect (PMIVSD) occurs within the first week after the event (41). In the current era of thrombolysis about 0.2% of patients develop a VSD as a result of septal necrosis. Medical management of these patients is limited and carries a 30-day mortality of 94% compared with 47% who were treated surgically (42).
