Keywords
- •Cardiac synchronization therapy in orthotopic heart transplant has been rarely reported.
- •Left ventricular conduction delay may occur simultaneously with atypical forms of right bundle branch block.
- •Cardiac resynchronization therapy may benefit selected patients with appropriate indications post heart transplant; however, the long-term outcomes of cardiac resynchronization therapy in heart transplant complicated by allograft vasculopathy are unknown.
