Utilization of 3 amplatzer occluders for closure of post-myocardial infarction ventricular septal defect

Abstract

This case report describes a patient who sustained a post-myocardial infarction ventricular septal defect (VSD) with an associated left ventricular aneurysm who developed cardiogenic shock and required an intra-aortic balloon pump for hemodynamic stabilization. After deployment of a single Amplatzer occluder (AGA Medical), a residual VSD measuring 0.5 cm was noted. Therefore, a second Amplatzer occluder was deployed and a minimal residual VSD remained. The patient remained hemodynamically stable throughout the procedure and was subsequently extubated with removal of intra-aortic balloon pump. Post-discharge, the patient was readmitted with congestive heart failure. A third Amplatzer device was deployed to ameliorate the recurrent VSD shunt. At 9-week follow-up, transthoracic echocardiogram was performed and findings included: 1) left ventricular ejection fraction of 62%; 2) appearance of 3 Amplatzer devices along the interventrcular septum seated well with no motion and residual shunt; 3) moderate diastolic dysfunction with pseudonormal left ventricular filling pattern; and 4) no valvular abnormalities. The patient had increased exercise tolerance with no shortness of breath at rest or with exertion. This case demonstrates the ...Continue Reading

Cardiogenic Shock

Cardiogenic shock is a devastating consequence of acute myocardial infarction and is associated with an extremely high mortality. Here is the latest research.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
