Echocardiography in cardiac resynchronization therapy.
Cardiac resynchronization therapy has been an effective option in patients with advanced heart failure. However, 20 to 30% of the patients do not benefit from this therapy. Clinical, electrocardiographic and echocardiographic criteria have been studied in an attempt to select patients who will benefit from a cardiac resynchronization therapy, and the echocardiogram is important both in the sele...
متن کاملCardiac resynchronization therapy guided by tissue Doppler
Nowadays, chronic congestive heart failure (CHF) remains a challenge despite significant progress in drug therapy. Cardiac resynchronization therapy (CRT) has revolutionized CHF treatment as a result of improved cardiac function based on optimal drug therapy [1, 2]. However, approximately 18% to 32% of patients who have undergone CRT do not experience positive curative effects [3, 4]. Recent st...
متن کامل"Hyper-response" evaluated by 3D echocardiography after cardiac resynchronization therapy.
Cardiac resynchronization therapy consists of a promising treatment for patients with severe heart failure, but about 30% of patients do not exhibit clinical improvement with this procedure. However, approximately 10% of patients undergoing this therapy may have hyperresponsiveness, and three-dimensional echocardiography can provide an interesting option for the selection and evaluation of such...
متن کاملCardiac resynchronization therapy guided by cardiovascular magnetic resonance
Cardiac resynchronization therapy (CRT) is an established treatment for patients with symptomatic heart failure, severely impaired left ventricular (LV) systolic dysfunction and a wide (> 120 ms) complex. As with any other treatment, the response to CRT is variable. The degree of pre-implant mechanical dyssynchrony, scar burden and scar localization to the vicinity of the LV pacing stimulus are...
متن کاملEchocardiographic 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...
