Key result
In a 60-year-old male heart transplant recipient, bidirectional ventricular tachycardia due to coronary allograft vasculopathy was successfully managed with antiarrhythmics and an implantable cardioverter-defibrillator.
Case Report (n=1)
This case report highlights coronary allograft vasculopathy as a potential novel etiology for bidirectional ventricular tachycardia in heart transplant recipients.
Alerts clinicians to coronary allograft vasculopathy in post-transplant bidirectional ventricular tachycardia; hypothesis-generating and requires confirmation before practice change.
Bidirectional ventricular tachycardia (BVT) is an uncommon type of polymorphic ventricular tachycardia (PVT) with alternating polarity of the QRS complex most commonly described digitalis toxicity. Recent data has demonstrated the possible molecular basis of this electrocardiographic phenomenon. To our knowledge this is the first reported case of BVT in a patient with orthotopic cardiac transplantation and coronary allograft vasculopathy.

Bhavnani et al. (2012) conducted a case report in Bidirectional ventricular tachycardia due to coronary allograft vasculopathy (n=1). Amiodarone, lidocaine, and ICD implantation was evaluated on Suppression of ventricular tachycardia. In a 60-year-old male heart transplant recipient, bidirectional ventricular tachycardia due to coronary allograft vasculopathy was successfully managed with antiarrhythmics and an implantable cardioverter-defibrillator.
