Ablation of Focal Atrial Tachycardia from a Large Left Atrial Diverticulum Using 3D Printing

Methodist Debakey Cardiovasc J. 2024 Sep 30;20(1):98-105. doi: 10.14797/mdcvj.1429. eCollection 2024.

Abstract

We present a case of a 45-year-old male with symptomatic supraventricular tachycardia. Electrophysiology study and 3-dimensional (3D) electroanatomic mapping showed a focal atrial tachycardia originating from a large left atrial diverticulum. Due to the unusual anatomy, 3D printing models were used to aid successful catheter ablation of the atrial tachycardia.

Keywords: 3D printing; ablation; atrial diverticulum; atrial tachycardia; congenital heart disease.
