Abstract:
After transcatheter aortic valve implantation (TAVI) in a 75-year-old male, chronic wide left bundle branch block (LBBB) developed. He experienced repeated episodes of decompensated systolic heart failure with severe systolic left ventricular dysfunction. After cardiac resynchronization therapy, his heart function improved substantially and he had no further admissions for heart failure. Cardiac resynchronization therapy can be effective in systolic heart failure associated with LBBB developing after TAVI.
