Atrial Flutter after Heart Transplantation: Mechanism and Catheter Ablation

Electroanatomical high-density mapping of different tachycardias in the right atrium after heart transplantation

“…After heart transplantation patients may develop different types of atrial arrhythmias in the recipient as well as in the donor atrium 1, 2, 3. This case report illustrates the use of a multipolar mapping catheter for fast, high-resolution mapping 2 of different tachycardias occurring simultaneously in both atria.…”

What Is the Mechanism of the Atrial Arrhythmia in a Patient After Orthotopic Heart Transplantation?

“…5 Although perimitral left atrial flutter has been described, it is quite uncommon. [5][6][7] No disclosures.…”

“…[1][2][3][4] The most commonly reported atrial arrhythmia after cardiac transplantation is cavotricuspid isthmus (CTI)-dependent atrial flutter in the donor atrium 5 ; this can be seen in patients after either bicaval or biatrial anastomoses. 5,6 Scar-related atrial flutter can also occur independently or concomitantly with CTI-dependent flutter. 5 Although perimitral left atrial flutter has been described, it is quite uncommon.…”

“…5 Although perimitral left atrial flutter has been described, it is quite uncommon. [5][6][7] No disclosures. The incidence of AF in cardiac transplant patients is highest in the perioperative period and then decreases steadily over time.…”

Anaesthesia Management for Ablation Therapy in Post Heart Transplant Arrhythmia

“…Radiofrequency ablation applies high-frequency, low-voltage electrical energy to the endocardium via a catheter-based electrode that leads to resistive thermal injury and subsequent coagulative necrosis of the tissue, thereby blocking reentrant electrical circuits causing atrial fibrillation [4]. Other reports have focused on the mechanism for atrial flutter post heart transplantation and potential therapy from cardiology perspective [5,6]. In this report we will focus on Anaesthesia management for ablation therapy in post heart transplant arrhythmia.…”
