Post-Myocardial Infarction Ventricular Septal Defect Closure by a Percutaneous Septal Occluder Device After Unsuccessful Surgical Closure: Never Lose Hope.

ABSTRACT

Post myocardial infarction ventricular septal defect (VSD) is a life-threatening complication following ST elevation myocardial infarction (STEMI). Current guidelines recommend the urgent VSD closure for its significant mortality. Despite VSD is generally treated by surgical repair, surgeons often refrain from early surgery due to extremely poor results. We report the case of a 76-year-old women admitted to our hospital for a subacute myocardial infarction complicated by acute heart failure with VSD and apical thrombosis. The patient underwent an urgent surgical repair of VSD with a bovine pericardium patch and concomitant double saphenous vein graft for the left anterior descending and the first diagonal branch. After two days an early surgical patch dehiscence was observed and a percutaneous closure was planned. Due to the particular morphology of the unnatural anatomy of the septum generated by the dehiscence, we decided to close the defect using an off-label device for ventricular rupture. A 30/30 mm Amplatzer ASD-MF occluder was successfully implanted. At one-year follow up the patient was alive without significant residual shunt.
