BACKGROUND Inadvertent damage to leads for transvenous pacemakers, implantable cardioverter-defibrillators, and cardiac resynchronization therapy defibrillators is an important complication associated with generator-replacement procedures. We sought to estimate the incidence and costs associated with transvenous lead damage following cardiac implantable electronic device replacement. METHODS ...
INTRODUCTION The SonR signal has been shown to reflect cardiac contractility. It is recorded with an atrial lead connected to a cardiac resynchronization therapy defibrillator. For the first time, clinical evidence on the use of the SonR signal in the monitoring of the clinical status of heart failure patients implanted with cardiac resynchronization therapy defibrillator are presented through ...
Fifteen years after the birth of resynchronization therapy, this technique has become one of the recommended treatments in severe heart failure patients, with low ejection fraction (4 35%), and conduction disorders (ORS > or = 120 ms). Based on large randomized clinical trials, the European recommendation is class I type (level of evidence A), to improve symptoms and survival of this patient po...
BACKGROUND Cardiac resynchronization therapy results in improved ejection fraction in patients with heart failure. We sought to determine whether these effects were mediated by changes in contractility, afterload, or volumes. METHODS AND RESULTS In 610 patients with New York Heart Association class I/II heart failure from the Resynchronization Reverses Remodeling in Systolic Left Ventricular ...
