An Unusual Complication of the Ventricular Septal Defect Closure by Device: Late Right Aortic Cusp Perforation.

Aortic regurgitation (AR) is a rare complication of transcatheter closure of perimembranous ventricular septal defects (pmVSD). It results from iatrogenic pinching of the aortic valve by the VSD occluder or perforation by the catheter. It is usually detected during control echocardiography (ECHO). The current study reports the first case of a late AR, which resulted from late right coronary cusp perforation by the VSD occluder. The current manuscript discusses the possible causes of late cusp erosion due to occluder, advantages of early operation in such cases, and an alternative treatment method where the occluder removal is not possible at the operation.
