Left Ventricular Pseudoaneurysm Following Surgical Repair of Ventricular Septal Defect in an Infant

A case presentation of acquired membranous ventricular septum aneurysm as a rare delayed complication of ventricular septal defect repair surgery: 10-year follow-up

BACKGROUND

Rare as membranous ventricular septal aneurysms (MVSA) is, the possibility that occurs after ventricular septum defect (VSD) repair surgery is even more uncommon.

PRESENTATION

A girl developed a MVSA 3 years after the VSD repair surgery at the age of 1 and increasing growth was noted during the follow-up. Aneurysm plication was carried done when she was 11 years old because it was observed to have a close relationship to the right coronary and obstructed the right ventricular outflow tract. Postoperative echocardiography follow-up revealed no abnormalities.

CONCLUSION

Though the prognosis of most patients with VSD repaired surgery was good, there remains varieties type of complications despite surgical advances. Accurate and rapid diagnosis of acute and delayed complications is essential to improve prognosis. In this case, the aneurysm was diagnosed by multiple imaging modalities and the girl underwent successful surgery again which provides direction for awareness and knowledge of delayed complications of VSD repair.

Subpulmonary pseudoaneurysm-a rare complication following surgical ventricular septal defect closure

In this report, we describe the surgical management of a subpulmonary pseudoaneurysm following surgical closure of ventricular septal defect in an infant. Diagnosis, pathogenesis, and surgical considerations for management of this complication are discussed.

A large basal left ventricular pseudoaneurysm following pediatric cardiac surgery

Left ventricular pseudoaneurysm (LV-PSA) is a rare complication in children, usually developing after cardiac surgery, percutaneous procedures, infections, or trauma. Herein, we report a case of large basal submitral LV-PSA in a 36-day-old baby, detected 26 days after cardiac operation for hypoplastic arch, aortic coarctation, and small ventricular septal defect. No complications occurred in the first postoperative course, and early postoperative echocardiograms were normal. Despite large dimension of pseudoaneurysm, the baby presented with only mild tachypnea. The baby was successfully operated. Pseudoaneurysm, besides rare, could have an extremely broad and insidious clinical presentation and had to be considered in post-cardiac surgery follow-up echocardiogram at any time lapse.
