Echocardiographic Improvements with Pacemaker Optimization in the Chronic Post Cardiac Resynchronization Therapy Setting
The current study assessed the acute effects of pacemaker optimization (PMO) on cardiac function using echocardiographic (ECHO) tissue Doppler imaging (TDI) in the post CRT setting. Data were analyzed from 50 consecutive patients clinically referred for PMO. Patients underwent a sequential ECHO/TDIguided PMO study to determine optimal pacemaker settings. In 34 of 50 patients a change in pacemak...
متن کاملPredictors of response to cardiac resynchronization therapy on pre-implantation cardiovascular magnetic resonance imaging
Methods Sixty-eight patients receiving CRT underwent pre-implant cardiovascular MRI followed by serial echocardiography at 3 and 6 months. Blinded measurement of Left Ventricular (LV) and Right Ventricular (RV) chamber dimensions, volumes and mass were performed from short axis cine datasets. LV dysynchrony was measured by septal to lateral wall delay. Total LV scar burden was determined from L...
متن کاملEffect of cardiac resynchronization therapy on reverse remodeling and relation to outcome: multicenter automatic defibrillator implantation trial: cardiac resynchronization therapy.
BACKGROUND Cardiac resynchronization therapy (CRT) plus implantation of an implantable cardioverter defibrillator (ICD) reduced the risk of death or heart failure event in patients with mildly symptomatic heart failure, left ventricular dysfunction, and wide QRS complex compared with an ICD only. We assessed echocardiographic changes in patients enrolled in the MADIT-CRT trial (Multicenter Auto...
متن کاملThoracoscopic Left Ventricular Lead Implantation in Cardiac Resynchronization Therapy
Cardiac resynchronization therapy is known to reduce morbidity and mortality in patients with advanced heart failure as a result of dyssynchrony and systolic dysfunction of the left ventricle. Placement of the left ventricular (LV) lead via the coronary sinus can be difficult. When LV lead implantation is difficult, a video-assisted epicardial approach can be a good alternative. Although there ...
متن کاملPredictors of response to cardiac resynchronization therapy in the Multicenter Automatic Defibrillator Implantation Trial with Cardiac Resynchronization Therapy (MADIT-CRT).
BACKGROUND We hypothesized that combined assessment of factors that are associated with favorable reverse remodeling after cardiac resynchronization-defibrillator therapy (CRT-D) can be used to predict clinical response to the device. METHODS AND RESULTS The study population comprised 1761 patients enrolled in the Multicenter Automatic Defibrillator Implantation Trial With Cardiac Resynchroni...
