Role of late surgical explantation of device from perimembranous ventricular septal defect for left bundle branch block and left ventricular dysfunction
Jayanth Kumar HV 1, Anand Mathew 1, Anand Subramanian 1,∗, Bharath A Paraswanath 1, Deepak Padmanabhan 1, Ashita Barthur 1, Jayranganath Mahimarangaiah 1 Device closures of perimembranous ventricular septal defects (pm VSD) have been carried out for over 2 decades now and are considered an accepted alternative to surgical closure in selected cases.1 While the development of heart block or aortic regurgitation had been major concerns in the past, the occurrence of complete left bundle branch block (LBBB) after device closure of pm VSD is quite rare, with few published reports.2,3 Development of LBBB is nevertheless significant, leading to septal dyssynchrony and progressive deterioration of left ventricular (LV) function. We report a case of resolution of LBBB after surgical explantation of Amplatzer duct occluder, several months after transcatheter pm VSD closure.
