Patient Selection for Cardiac Resynchronization Therapy
Cardiac resynchronization therapy (CRT) is a relatively new therapy for patients with symptomatic heart failure resulting from systolic dysfunction. CRT is achieved by simultaneously pacing both the left and right ventricles. Biventricular pacing resynchronizes the timing of global left ventricular depolarization and improves mechanical contractility and mitral regurgitation. Published clinical...
متن کاملSelection for Cardiac Resynchronization Therapy
SEE PAGE 969 C ardiac resynchronization therapy (CRT) is a highly effective treatment for some patients with heart failure. Current guidelines recommend the implantation of CRT devices in patients with left ventricular (LV) dysfunction and electrical dyssynchrony, evidenced by a left bundle branch block (1). Unfortunately, not all patients suitable for CRT derive symptomatic benefit—an unsatisf...
متن کاملPatient selection and echocardiographic assessment of dyssynchrony in cardiac resynchronization therapy.
Appropriate cardiac resynchronization therapy (CRT) enhances quality of life and improves survival in patients with refractory heart failure due to systolic dysfunction and mechanical dyssynchrony. On the assumption that the main therapeutic mechanism of CRT is the correction of dyssynchronous myocardial contraction, imaging-based measures of dyssynchrony have been intensely investigated with t...

متن کاملCardiac resynchronization therapy: evaluation of ventricular dysynchrony and patient selection.
Cardiac resynchronization therapy (CRT) is an established treatment modality for systolic heart failure. Aimed to produce simultaneous biventricular stimulation and correct the lack of ventricular synchrony in selected patients with congestive heart failure, CRT has shown to improve mortality and reduce hospital admissions when compared to medical treatment. At present, the indication criteria ...
