Atrioventricular Nodal Reentrant Tachycardia in Transplanted Heart

Jozef Gonsorcik, Mikulas Hunavy*, Branislav Stancak and Peter Gaspar

Patients after heart transplantation may develop variety of supraventricular or ventricular arrhythmias; however atrioventricular nodal reentrant tachycardia (AVNRT) is very rare. We report a case of a young patient, who underwent orthotopic heart transplantation (OHT) due to nonischemic dilated cardiomyopathy. 10 years after transplantation he began to perceive palpitations and on outpatient visit an AVNRT has been recorded on standard 12-lead ECG. Patient underwent electrophysiology study (EPS) where AVNRT was induced and successful radiofrequency catheter ablation (RFCA) has been performed. Currently, patient is symptoms free at 3 years follow up.
