CONTEXT Progressive heart failure is the most common mechanism of death among patients with advanced heart failure. Cardiac resynchronization, a pacemaker-based therapy for heart failure, enhances cardiac performance and quality of life, but its effect on mortality is uncertain. OBJECTIVE To determine whether cardiac resynchronization reduces mortality from progressive heart failure. DATA S...
BACKGROUND We tested the hypothesis that prophylactic cardiac-resynchronization therapy in the form of biventricular stimulation with a pacemaker with or without a defibrillator would reduce the risk of death and hospitalization among patients with advanced chronic heart failure and intraventricular conduction delays. METHODS A total of 1520 patients who had advanced heart failure (New York H...
BACKGROUND Although the benefits of cardiac resynchronization therapy are well established in selected patients with heart failure and a prolonged QRS duration, salutary effects in patients with narrow QRS complexes remain to be demonstrated. METHODS AND RESULTS The Evaluation of Resynchronization Therapy for Heart Failure (LESSER-EARTH) trial is a randomized, double-blind, 12-center study th...
Heart failure is one of the most prevalent diseases in industrialized countries. Although the prognosis of patients with heart failure is still poor, in recent decades new therapies have been investigated in order to improve quality of life and survival. However, up to 30% of the patients with advanced heart failure present disturbances in intraventricular conduction, and this produces asynchro...

Background: Oral clefts are among the most common congenital anomalies. Infants with oral clefts often have other associated congenital defects, especially congenital heart defects. The reported incidences and the types of associated malformations and congenital heart defects vary between different studies. The purpose of this study was to assess the incidence of associated congenital heart def...
Cardiac resynchronization therapy (CRT) has been shown to improve cardiac function, diminish hospitalization frequency, and enhance quality of life in selected heart failure patients. This benefit is mostly due to improved synchronization of ventricular contraction in the diseased heart. Since heart failure patients represent a heterogeneous group, cardiac resynchronization therapy must be tail...
INTRODUCTION AND OBJECTIVES A cross-sectional study of cardiac resynchronization therapy use in Spain was performed to analyze problems with indications, implantation, and patient follow-up. METHODS Spanish cardiac resynchronization therapy implanter centers were identified, then the department members were surveyed and the data were recorded by each implantation team. RESULTS Eighty-eight ...
