ABSTRACT
Objective To investigate the characteristics,occurrence times and management of cardiac erosion after transcatheter closure of ASD,and to discuss the mechanism and predictive factor of erosion.Methods We analyzed all the cases who received transcatheter ASD closure from September 1997 to September 2016 in our hospital retrospectively.Results 9 cases (9/6903,0.13％) were reported to have cardiac erosion events after device closure ASD of including 2 cases of acute cardiac tamponade needed pericardiocentesis,2 cases of aorta-to right-atrial fistula needed transcatheter closure or operative repair and 5 cases of perforation of the anterior leaflet of mitral valve.1 case with MV anterior leaflet perforation presented with hemolysis and required surgical repair.Cardiac erosion events were found at average 52.9±68.3 days (1-180days) after the ASD closure.Conclusions Cardiac erosion is a rare but serious complication of device closure for ASD.Erosion events are mostly attributed to device over-sizing or deficient retro-aortic rims.It is important for a strict follow-up,early deduction and timely disposition when an erosion event is identified.occurring.
