Hemodynamic Effects of Long-Term Cardiac Resynchronization Therapy Analysis by Pressure-Volume Loops
Background—Acute hemodynamic effects of cardiac resynchronization therapy (CRT) were reported previously, but detailed invasive studies showing hemodynamic consequences of long-term CRT are not available. Methods and Results—We studied 22 patients scheduled for implantation of a CRT device based on conventional criteria (New York Heart Association class III or IV, left ventricular [LV] ejection...
متن کاملLong-term retention of cardiac resynchronization therapy.
OBJECTIVES The purpose of this study was to determine the frequency and causes of intermittent and permanent loss of cardiac resynchronization therapy (CRT) in patients who have undergone the successful implantation of a transvenous defibrillator that delivers CRT (CRT-D). BACKGROUND The causes of loss of CRT have not been described. METHODS The records of 512 patients who underwent an atte...
متن کاملCardiac resynchronization therapy: long-term alternative to cardiac transplantation?
BACKGROUND Cardiac transplantation remains the gold standard for treating end-stage heart failure. However, because of donor shortage and posttransplant complications alternative options are needed. METHODS We investigated the impact of cardiac resynchronization therapy on clinical outcome in 545 patients with left bundle-branch block and interventricular asynchrony, who fulfilled the cardiac...
متن کاملHemodynamic changes during cardiac resynchronization therapy.
Cardiac resynchronization therapy (CRT) is a new method for the correction of inter- and/or intraventricular conduction delays of patients with heart failure. The long-term impact of CRT on central hemodynamics is not fully characterized. We performed complete right heart catheterization studies in 31 patients receiving a CRT device pre and 6 months after implantation. Most of the patients impr...
