Multiple atrial tachycardias after orthotopic heart transplantation: A case report and literature review

A storm in the desert: Ablation of a left atrial tachycardia in a heart transplant recipient

“…Shi and colleagues 5 offered a review of the existing literature and described the case of a patient who underwent orthotopic heart transplant with biatrial anastomosis technique and developed multiple ATs: a focal one arising from the donor’s right atrium, another microreentrant AT in the donor’s left atrium, and a macroreentrant perimitral AFL. All these arrhythmias were successfully ablated after careful high-density mapping.…”

A Tale of 2 Hearts

“…The observation that termination of the AFL with sinus rhythm restoration did not affect the TCL of the AT proves that these 2 arrhythmias were independent and occurred in electrically isolated areas of the RA (2) and that only the AFL was evident on the electrocardiogram because the AT was contained in the native RA. Finally, because medical therapy often fails in patients with these arrhythmias, high-density mapping techniques are rapid and accurate tools to facilitate the understanding of these complex arrhythmia circuits and to guide a successful ablation strategy (3) .…”
