Cardiac Resynchronization Therapy
نویسنده
چکیده
Cardiac resynchronization therapy (CRT) has become a well-established and important therapeutic option in the management of patients with symptomatic systolic heart failure. Improvement in quality of life and exercise tolerance as well as reduction in hospitalizations for heart failure have been demonstrated repeatedly (1,2). In addition, reverse ventricular remodeling and improvement in left ventricular ejection fraction are seen in the majority of patients. Reduction in mortality has also been shown, whether or not CRT is combined with an implantable cardioverter-defibrillator (ICD) (3). However, despite the fact that advanced heart failure is ssociated with an increased risk of sudden cardiac death, the ffect of CRT on the risk of ventricular tachyarrhythmias has ot been as clear cut.

Cardiac resynchronization therapy for congestive heart failure.
Cardiac resynchronization represents a novel therapeutic strategy for the treatment of congestive heart failure due to systolic dysfunction. Since its modest beginnings in the 1990s, cardiac resynchronization therapy has gained widespread acceptance as a useful adjunct to pharmacologic therapy for congestive heart failure. Randomized trials have consistently shown functional improvement in pati...
متن کامل[Three-dimensional imaging in cardiac resynchronization therapy].
Cardiac resynchronization therapy improves clinical symptoms and prognosis of heart failure patients. However, it has been shown that up to 40% of patients do not respond to this therapy. Three main determinants of cardiac resynchronization therapy response have been identified: left ventricular dyssynchrony, left ventricular lead position, and extent and location of myocardial scar tissue. Two...
متن کاملCardiac Resynchronization Therapy for Heart Failure
The weight of evidence supporting the routine use of cardiac resynchronization therapy, or atrial-synchronized biventricular pacing, as a treatment for patients with moderate-to-severe chronic systolic heart failure and ventricular dyssynchrony is now quite substantial. Results from mechanistic studies, observational evaluations, and randomized, controlled trials have consistently demonstrated ...
متن کاملCardiac Resynchronization Therapy in Women
Despite underrepresentation of women in cardiac resynchronization therapy studies, it has been conclusively shown that women demonstrate greater benefit than men in functional status, reverse cardiac remodeling, and survival and female gender remains an independent predictor of greater response to cardiac resynchronization therapy after adjustment for various other factors. Eligible female pati...
متن کاملCardiac Resynchronization Therapy
Cardiac Resynchronization Therapy. Cardiac resynchronization therapy (CRT) is a recently developed approach to treat dilated heart failure with discoordinate contraction. Such dyssynchrony typically stems from electrical delay that then translates into mechanical delay between the septal and lateral walls. Over the past decade, many studies have examined the pathophysiology of cardiac dyssynchr...
متن کاملEchocardiography 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...
