Ruptured sinus of Valsalva aneurysm (RSVA), a rare form of left-to-right shunt, is being increasingly corrected with transcatheter closure (TCC) with promising immediate and mid-term results. Complete heart block (CHB) following TCC of perimembranous ventricular septal defect is a well-described albeit worrisome complication. We describe a hitherto unreported case of development of CHB following TCC of RSVA that responded to high-dose steroids. The patient continues to remain in sinus rhythm without CHB 6 months later.
