Ventricular remodeling in right ventricular apical pacing.
OBJECTIVE To determine ventricular remodeling (VR) and the role of clinical and functional variables in patients with normal cardiac function who underwent right ventricular apical pacing (RVAP). METHODS Among the 268 consecutive patients with standard pacemaker due to complete atrioventricular block (CAVB), those with left ventricular ejection fraction (LVEF) < 55% and left ventricular end-d...
متن کاملUpgrading to resynchronization therapy after chronic right ventricular pacing improves left ventricular remodelling.
AIMS Chronic right ventricular (RV) pacing may impose ventricular dyssynchrony leading to LV remodelling and is associated with increased morbidity and mortality. Upgrading patients with chronic RV pacing to cardiac resynchronization therapy (CRT) may be considered to restore synchronicity and prevent these deleterious effects. METHODS AND RESULTS A total of 172 patients from two tertiary cen...
متن کاملVentricular resynchronization: comparing biventricular and bifocal right ventricular pacemakers.
OBJECTIVE To analyze the conventional biventricular pacing (BV) and the bifocal (BF) right ventricular (RV) pacing, and to perform a comparative analysis of these two techniques in relation to clinical, functional and echocardiographic parameters in a population without the exclusion criteria of the major studies. METHODS A prospective non-randomized analysis of 36 patients undergoing surgery...
متن کاملInter-stage right ventricular remodeling in hypoplastic left heart syndrome
Methods A retrospective analysis of the serial MRI scans of all patients with HLHS who had undergone palliation through to completion of Fontan was undertaken. Re-analysis was undertaken by two members of the research team who had previously shown good intrauser variability. Ethical and institutional approval was obtained. All scans had been performed with general anaesthesia on a Philips 1.5 T...
متن کاملquantification of aortic regurgitation severity by left ventricular to right ventricular stroke volume ratio
background: echocardiography is the most common test used for the evaluation of aortic regurgitation (ar). however, the role of echocardiography as an available and inexpensive method in the quantification of ar by the left ventricle to right ventricle stroke volume ratio (lv/rv sv ratio) has not been completely investigated. methods: between june 2005 and december 2007, 132 consecutive patient...
