Catheter Ablation of Atrial Arrhythmias After Orthotopic Heart Transplantation.

This prospective study evaluated Orthotopic heart transplantation (OHT) creates a surgically altered electrophysiologic substrate defined by the suture-line scar, residual recipient atrial tissue, and autonomic de. Key finding: Orthotopic heart transplantation (OHT) creates a surgically altered electrophysiologic substrate defined by the suture-line scar, residual recipient atrial tissue, and autonomic denervation, that fundamentally alters the mechanisms, presentation, and management of atrial tachyarrhythmias.
