Electrical resychronization of failing right ventricle.
Right Ventricle To the Editor: Dubin et al1 recently published their experience with electrical resynchronization of the failing right ventricle (RV) in patients with congenital heart disease (CHD) (6 of 7 with tetralogy of Fallot). The authors used temporary atrioventricular (AV) sequential pacing from 3 RV sites with a paced AV delay set to 90% of the spontaneous PR interval to alleviate the ...
متن کاملElectrical 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 کاملFlow in the Failing Ventricle
Heart failure is diverse in its manifestations and pathophysiology with changes in chamber size and volume, wall motion, valvular competence, intracardiac pressures, and electrical events. These are routinely measured with wellestablished methods. However, it is common to observe different degrees of compensation despite echocardiographically similar degrees of cardiac dysfunction. How can we e...
متن کاملSuccessful permanent resynchronization for failing right ventricle after repair of tetralogy of Fallot.
A fter repair of tetralogy of Fallot with significantly decreased exercise tolerance, a 17-year-old symptomatic boy underwent successful permanent resynchronization of a failing right ventricle (RV). The patient had surgical repair including pulmonary valvulotomy, infundibulectomy, and pericardial right ventricular outflow tract (RVOT) plasty at 1 year of age. At 3 years of age, he underwent re...
متن کاملDownregulation of MicroRNA-126 Contributes to the Failing Right Ventricle in Pulmonary Arterial Hypertension.
BACKGROUND Right ventricular (RV) failure is the most important factor of both morbidity and mortality in pulmonary arterial hypertension (PAH). However, the underlying mechanisms resulting in the failed RV in PAH remain unknown. There is growing evidence that angiogenesis and microRNAs are involved in PAH-associated RV failure. We hypothesized that microRNA-126 (miR-126) downregulation decreas...
