Surgical repair of left ventricular pseudoaneurysm following perventricular device closure of muscular ventricular septal defect

Abstract

Left ventricular pseudoaneurysm formation following perventricular device closure of a muscular ventricular septal defect is a rare complication. We describe a case of left ventricular pseudoaneurysm in an infant with Swiss-cheese ventricular septal defects who initially underwent closure with an Amplatzer device using a hybrid approach. The pseudoaneurysm was successfully resected surgically.

Percutaneous closure of left ventricular pseudoaneurysm

“…Congenital heart defect repair (Ross procedure [24], ventricular septal defect (Swiss-cheese) repair [66] [7,31,35,36,41,43,51,52], and the remaining 42 (80.8%) patients had 59 symptoms, with chest pain and dyspnoea/shortness of breath being the most common (Table II). The ejection fraction of the patients was 31.6 ±13.9% (range: 16-55%; median: 25%) (n = 7) [15,36,42,45,53,55,68].…”

Ventricular Pseudoaneurysms After Perventricular Closure of Ventricular Septal Defect

“…It was treated using a percutaneous occluding device. However, an echocardiogram showed residual flow within the defect at 48 hours, and the pseudoaneurysm ultimately required surgical closure [4].…”

“…Less common causes include posttraumatic (7%) or infectious (5%) disorders [1]. To our knowledge, there are only three reports of this entity occurring after perventricular closure of ventricular septal defects (VSDs) in the pediatric population [2][3][4]. We report the case of an 18-month-old patient who developed two LV pseudoaneurysms after perventricular device closure of a VSD performed at 3 months of age.…”

Recurrent aortic root pseudoaneurysm after transcatheter occlusion-A word of caution

“…Endovascular occlusion devices have been used to treat pseudoaneurysms when conventional surgical repair is deemed to be high‐risk and stent graft implantation is anatomically inappropriate . However, there are now several reports describing recurrent pseudoaneurysms and cardiac perforations following the insertions of these devices . We report a case of a recurrent aortic root pseudoaneurysm following the successful deployment of an endovascular occlusion device in a patient with a previous surgical repair for a type A aortic dissection.…”
