Valve-sparing reimplantation for neoaortic root dilatation and regurgitation with an unbalanced cusp after the arterial switch operation

Abstract

A 13-year-old male presented with neoaortic root dilatation and severe aortic valve regurgitation 13 years following an arterial switch operation. The valve cusps were unbalanced due to an enlarged non-coronary cusp. A valve-sparing reimplantation with a cusp plication was performed which resulted in a competent valve with trivial regurgitation. Thus, even in an unbalanced cusp, valve-sparing reimplantation can be used for neoaortic root dilatation and valve regurgitation after an arterial switch operation.

Reoperation for left atrioventricular valve failure in repaired atrioventricular septal defect: Can more valves be preserved in the current era?

“…Valve repair in congenital surgery is now being increasingly performed in the aortic, mitral, and tricuspid positions. [23][24][25][26] The present study shows that in the current era it is increasingly possible to achieve a successful redo-LAVV repair with good early and long-term results.…”

Non-anastomotic failure of woven Dacron tube grafts in the thoracic aorta in young adults

“…By addressing the compromised graft percutaneously, the complications associated with reoperations can be avoided. Our experience also shows the importance of annual imaging follow‐up in all congenital patients who have had any type of repair involving the aorta, since there have been reports of native aortic aneurysmal formation in adults who have had repairs of congenital lesions in childhood and as adolescents . These changes in the wall of the native aorta may also contribute to changes in the interposition Dacron grafts, both in the body and at the anastomosis.…”

Repair of an aneurysm of the ascending aorta and arch in an infant with Loeys-Dietz syndrome

“…While we have shown that AO and arch replacement with debranching of neck vessels using SACP through PTFE graft to RSCA in an infant is feasible, long‐term angiotensin receptor blocker therapy is required to prevent aneurysmal progression. In addition, periodical evaluation with TTE every 3‐6 months and yearly CT aortogram is required to assess disease progression which has been shown to occur even into adulthood in these young patients who have undergone repairs of the aortic root, and the AO and arch …”
