CRT-D implantation may be a useful therapeutic approach for managing systemic RV failure with wide QRS and atrial fibrillation in patients with corrected transposition of the great arteries.
CRT-D may benefit systemic RV failure with wide QRS and AF; leaves open generalizability beyond this single case.
A 32‐year‐old man developed systemic right ventricular (RV) heart failure after ventricular septal defect (VSD) closure and tricuspid valve replacement for corrected transposition of the great arteries with VSD and Ebstein anomaly. He subsequently experienced RV failure with wide QRS and atrial fibrillation (AF). Because corrective surgery for this condition seemed over risky, we decided to perform cardiac resynchronization therapy with implantation of an implantable cardioverter defibrillator (CRT‐D). After CRT‐D device implantation, the patient showed improved performance status in terms of New York Heart Association functional class, B‐type brain natriuretic peptide levels, RV ejection fraction and cardiac electrical rhythm. CRT‐D implantation is a useful approach for systemic RV failure with wide QRS duration showing right bundle branch block and AF.
