Congestive heart failure induced by recipient atrial tachycardia conductedto the donor atrium after orthotopic heart transplantation: Complete regression after successful radiofrequency ablation

Graft Failure and Recipient Atrial Tachycardia. We describe the case of a 3 0-year-old female patient who developed an interatrial tachycardia from the recipient to the donor atrium associated with signs of congestive heart fa ilure 5 years after orthotopic heart transplantation. The patient underwent catheter mapping followed by successful radiofrequency (RF) ablation at th e site of the presumed electrical connection between the recipient and the donor atria, through the interatrial surgical suture line, with stable reco very of sinus rhythm and disappearance of signs of left ventricular dysfunc tion, RF catheter ablation is confirmed to be feasible and safe in the trea tment of heart transplant patients even in the presence of rare forms of ar rhythmias, thus offering a cure for tachycardia to these patients.
