Post-Myocardial Infarction Ventricular Septal Defect: A Comprehensive Review

Post-myocardial infarction (MI) ventricular septal defect (VSD) is a rare but potentially catastrophic mechanical complication that occurs in <1% of patients following a myocardial infarction and it is associated with a high morbidity and mortality despite improvements in medical and surgical therapies. Post-MI VSD is a medical emergency and outcome is very poor in medically treated patients. Treatment of choice remains surgical closure of defect and transcatheter defect closure less so. We performed a comprehensive review of the clinical presentation and management options of post-MI VSD.
