OBJECTIVE A large spectrum of congenital heart diseases requires valved conduits to establish an anatomical continuity between the right ventricle outflow tract (RVOT) and the pulmonary artery. The aim of the present study was to compare the incidence of graft replacement in patients receiving the Contegra conduit (bovine jugular vein graft) with that in patients receiving a homograft implanted...

PURPOSE Prolonged pacing from the right ventricular apex (RV) is associated with the LV dyssynchrony leading to progressive left ventricular dysfunction and increased morbidity and mortality. Alternate RV pacing sites-in particular the mid- RV septum and the RV outflow tract (RVOT) septum were considered, but no clear benefit was proven till now for this pacing sites. This may be due to the het...

INTRODUCTION In the right ventricle, selective site pacing (SSP) has been shown to avoid detrimental hemodynamic effects induced by right ventricular apical pacing and, in the right atrium, to prevent the onset of atrial fibrillation and to slow down disease progression. The purpose of our multicenter observational study was to describe the use of a transvenous 4-French catheter-delivered lead ...

BACKGROUND The underlying electrophysiological mechanism that causes an abnormal ECG pattern and ventricular tachycardia/ventricular fibrillation (Vt/VF) in patients with the Brugada syndrome (BrS) remains unelucidated. However, several studies have indicated that the right ventricular outflow tract (RVOT) is likely to be the site of electrophysiological substrate. We hypothesized that in patie...

AIMS There are many reports on the ECG characteristics of idiopathic outflow tract ventricular arrhythmias (OT-VAs) to predict their origin. However, differentiating near regions using 12-lead ECGs is still complicated. The synthesized 18-lead ECG derived from the 12-lead ECG can provide virtual waveforms of the right-sided chest leads (V3R, V4R, and V5R) and back leads (V7, V8, and V9). The ai...

Background. The relationship between C-reactive protein (CRP) elevation and ventricular tachycardia (VT) in arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is unclear. Methods and Results. In 91 consecutive patients with either ARVD/C with or without VT (cases) or idiopathic right ventricular outflow tract (RVOT) tachycardia (controls), blood sampling were taken to determine ...

The effect of lidocaine (n = 6) and procainamide (n = 12) on electrogram characteristics from electrically normal right ventricular and electrically abnormal left ventricular endocardial sites was determined in 18 patients with prior myocardial infarction. Bipolar electrograms were recorded during sinus rhythm with No. 6F catheters positioned at a left ventricular abnormal site (electrograms fu...

DESCRIPTION A 54-year-old asymptomatic man was detected to have a prominent left heart border on a routine chest x-ray done during his annual health check (figure 1, arrows). Echocardiogram revealed a cystic lesion occupying the space antero-lateral to the right ventricular outflow tract (RVOT; figure 2). The cystic cavity did not produce any compression of the RVOT. CT of the chest showed a 6×...

BACKGROUND The purpose of this study was to systematically study diagnostic and prognostic electrocardiographic (ECG) characteristics of arrhythmogenic right ventricle dysplasia/cardiomyopathy (ARVD/C). METHODS AND RESULTS The patient population included 50 patients with ARVD/C (27 males, 23 females; mean age 38+/-15 years). We also analyzed the ECG of 50 age- and gender-matched normal contro...
