Through analyzing their nursing 52 children undergoing right ventricular outflow tract reconstruction with cryopreserved viable valved homograft, the authors concluded such severe complications as pericardial tamponade, low cardiac output syndrome, arrhythmia and chylothorax induced by right ventricular outflow tract reconstruction.

Curative radiofrequency catheter ablation of frequent monomorphic ventricular ectopic beats originating from right outflow tract;

Observation on radiofrequency catheter ablation used in patients with ventricular ectopic beats originating from right ventricular outflow tract

Objective:To determine the circadian variation and its clinical implications of ventricular arrhythmais in the patients with idiopathic ventricular tachycardia originating from right ventricular outflow tract (IRVOT-VT).

Purpose: To study the MRI feature of right ventricular outflow tract in patients with symptomatic right ventricular outflow tract ectopic activity.

Objective: The aim of our study was to compare cardiac output (CO) during short-term atrioventricular sequential pacing from the right ventricular apex and from the outflow tract of the right ventricle, to assess if short-term right ventricular outflow tract pacing were much better than right ventricular apical pacing.

Background:As proved by more and more clinical and experimental researches, right ventricular pacing for long time inducing LBBB may cause hemodynamic disorder and systolic dys-synchrony of LV,which drives people to find new alternative pacing site-right ventricular outflow tract pacing.
