In the next decade, "better" management will be defined by cost effectiveness including morbidity, mortality, and cost. We used a cost-effectiveness model for children with Wolff-Parkinson-White syndrome (WPW) and supraventricular tachycardia (SVT) comparing medical, surgical, and catheter ablative treatment between age 5 years (estimated average age at first recurrence after infancy) and age 2...

BACKGROUND Catheter ablation of ventricular tachycardia (VT) in nonischemic heart diseases can be challenging, and outcomes across different diseases are incompletely defined. The aim of this study was to describe the outcomes after catheter ablation for nonischemic VT in a large cohort and to compare the electrophysiological findings and outcomes according to the type of underlying disease. ...

RATIONALE Congenital ventricular diverticulum is a rare cardiac malformation with a prevalence of about 0.26% in unselected adult patients during other diagnostic procedures. Ventricular arrhythmia originating from outflow tract diverticulum is even rarer and its etiology, epidemiology and proper treatment still remain controversial. PATIENT CONCERNS We present 2 cases of isolated outflow tra...

BACKGROUND Catheter ablation of left-sided atrial arrhythmias generally is performed using a transfemoral venous approach through the inferior vena cava (IVC). In this report, we assessed the feasibility of a percutaneous transhepatic approach to ablation of left-sided atrial arrhythmias in 2 patients with interruption of the IVC. METHODS AND RESULTS Patient 1 had atrial flutter in the settin...

background: after radiofrequency catheter ablation of arrhythmias, patients have to bed rest for 4-6 h to prevent bleeding and hematoma. however, such a rest may cause back pain in the patients. the aim of this study was to determine the effects of continuous change in body position during and after the radiofrequency ablation on the back pain. materials and methods: in a quasi‑experimental des...

Ebstein’s anomaly is a rare congenital heart disease in which the tricuspid valve is displaced toward the apex of the right ventricle (RV). It is commonly associated with atrial arrhythmia, especially Wolff-Parkinson-White syndrome. In fact, up to 20% of patients with Ebstein’s anomaly have 1 or more accessory pathways owing to tricuspid valve malformation, most of which are located along these...

Abstract Background The Advisor™ HD Grid Mapping Catheter (Abbott Technologies, Minneapolis, MN) has been recently introduced. Although the clinical use of mapping catheter is well described in adults with no congenital heart disease, there limited data on feasibility using multipolar to create voltage and activation disease. purpose this study was evaluate safety technical during ablation atri...

BACKGROUND Based on data from studies of atrial fibrillation ablations, optimal parameters for the TactiCath (TC; St. Jude Medical, Inc) force-sensing ablation catheter are a contact force of 20 g and a force-time integral of 400 g·s for the creation of transmural lesions. We aimed to evaluate TC in pediatric and congenital heart disease patients undergoing ablation. METHODS AND RESULTS Compr...
