Giant Partial Endocardial Cushion Defect Challenging Mitral Valve Replacement in Adults: Surgical Approach.

Abstract

Atrial septal defect (ASD) is one of the most common congenital heart diseases diagnosed in children and adults [ [1] Steele P.M. Fuster V. Cohen M. Ritter D.G. McGoon D. Isolated atrial septal defect with pulmonary vascular obstructive disease – long-term follow-up and prediction of outcome after surgical correction. Circulation. 1987; 76: 1037-1042 Crossref PubMed Scopus (236) Google Scholar ]. Interventional closure devices or surgical patch closure are potential treatment options in haemodynamically relevant ASD. Concomitant severe mitral valve regurgitation is impeded by persisting type I ASD, as a congenital partial endocardial cushion defect (PECD) might be present. Partial endocardial cushion defect is a rare form of congenital heart failure, accounting for about 3% of the overall incidence [ [2] Robinson C.L. Merriman J.E. Kilduff C.J.
