Acquired right atrial appendage to right ventricle accessory pathway in a lateral tunnel Fontan patient: Successful ablation via transconduit approach
نویسندگان
چکیده
Introduction The management of supraventricular arrhythmias after the Fontan procedure with catheter ablation represents a significant challenge. This can be due to the access problems that are created by the currently used modification of the procedure, which uses an extracardiac conduit, as well as to the complex anatomic substrate that can be created by a combination of congenital and acquired reasons. We report a case illustrating both of these aspects of the procedure and the potential solutions to the problems.

Is the extracardiac conduit the preferred Fontan approach for patients with univentricular hearts? The extracardiac conduit is the preferred Fontan approach for patients with univentricular hearts.
Fontan palliation for single-ventricle patients was first described in 1971.1 The original approach was in the form of a classic atriopulmonary Fontan connection, bypassing the nonfunctional right ventricle. After recognizing the long-term complication of an atriopulmonary connection (right atrial dilation, arrhythmias, and thrombus formation), modifications have been made. The atriopulmonary c...
متن کاملTransbaffle radiofrequency ablation of reentrant atrial tachycardia in a child with hypoplastic left heart syndrome after Fontan correction.
Patients with functionally single ventricle undergo several operations in order to regulate pulmonary blood flow; however, it limits the access to the chambers of the heart. Incisional tachycardia after surgery is frequently life threatening. Because it rarely responds to medical treatment, radiofrequency (RF) ablation is an optimal option with a relatively high success rate. A 7-year-old boy w...

A male infant with the rare lesion of unguarded tricuspid orifice in the setting of pulmonary valve atresia, intact ventricular septum, and a hypoplastic right ventricle is described. The patient presented with cyanosis at 1 day old; transcutaneous oxygen saturations were between 20% and 30% in room air, and 60% in 100% inspired oxygen. Pre-excitation was found incidentally on the ECG and the p...

INTRODUCTION Surgical strategy for patients born with a physiological univentricular heart has evolved from atrio-pulmonary (AP) Fontan (right atrium (RA) to pulmonary artery) to its modification, total cavopulmonary connection (TCPC), with the goal of reduced post-operative incidence of supraventricular tachycardia (SVT). However, TCPC patients may also present with symptomatic atrial tachycar...
