Electrical resynchronization: a novel therapy for the failing right ventricle.
BACKGROUND Many patients with congenital heart disease develop right ventricular (RV) failure due to anatomy and prior therapy. RV problems may include right bundle-branch block (RBBB), volume loading, and chamber enlargement. Because the failing RV may have regional dyskinesis, we hypothesized that resynchronization therapy might augment its performance. METHODS AND RESULTS We studied 7 pati...

متن کاملSelecting patients for cardiac resynchronization therapy: electrical or mechanical dyssynchrony?
Cardiac resynchronization therapy (CRT) markedly reduces morbidity and mortality in patients with heart failure and prolonged QRS duration. Landmark trials have included over 4000 patients based on their electrocardiogram. A few small, observational, non-randomized, single centre studies of short duration have suggested that echocardiographic measurement of mechanical dyssynchrony may better id...
متن کاملIntegration of mechanical, structural and electrical imaging to understand response to cardiac resynchronization therapy.
INTRODUCTION AND OBJECTIVES There is extensive controversy exists on whether cardiac resynchronization therapy corrects electrical or mechanical asynchrony. The aim of this study was to determine if there is a correlation between electrical and mechanical sequences and if myocardial scar has any relevant impact. METHODS Six patients with normal left ventricular function and 12 patients with l...
متن کاملElectrical and Mechanical Ventricular Activation During Left Bundle Branch Block and Resynchronization
Cardiac resynchronization therapy (CRT) aims to treat selected heart failure patients suffering from conduction abnormalities with left bundle branch block (LBBB) as the culprit disease. LBBB remained largely underinvestigated until it became apparent that the amount of response to CRT was heterogeneous and that the therapy and underlying pathology were thus incompletely understood. In this rev...
