Transcatheter aortic valve implantation (TAVI) is sometimes associated with severe complications due to the unpredictability of such closed-chest procedures. Reported complications include atrioventricular blocks, vascular complications, aortic root rupture, aorto-right ventricular fistulas, and aortic dissections. Herein is presented the case of an 88-year-old female with a late atrioventricular septal defect that developed after TAVI.
