Left intraventricular myocardial deformation dyssynchrony identifies responders to cardiac resynchronization therapy in patients with heart failure.
AIMS We tested the hypothesis that dyssynchrony of left ventricular (LV) myocardial deformation evaluated by ultrasound can predict success of cardiac resynchronization therapy (CRT) in patients with heart failure (HF). METHODS AND RESULTS Thirty-seven patients with dilated cardiomyopathy, New York Heart Association class III-IV, LV ejection fraction (EF) < or =35%, QRS > 120 ms were studied ...
متن کاملWhat happens to non-responders in cardiac resynchronization therapy?
INTRODUCTION AND OBJECTIVES Left ventricular reverse remodeling (LVRR) is strongly related to the long-term prognosis of patients undergoing cardiac resynchronization therapy (CRT). The aim of this study was to assess the long-term clinical outcome of patients without LVRR at six months after CRT implantation and to determine the prognostic impact of clinical response in this population. METH...
متن کاملEchocardiographic assessment of right ventricular function in responders and non-responders to cardiac resynchronization therapy
INTRODUCTION The aim of this study was to determine whether baseline right ventricular (RV) function assessed by standard echocardiography may indicate patients who will respond to cardiac resynchronization therapy (CRT). MATERIAL AND METHODS The data of 57 patients (54 men, 95%), aged 66.4 ±8.7 years with heart failure (HF) having a CRT device implanted were collected. All patients had left ...
متن کاملVentricular arrhythmias in super-responders to cardiac resynchronization therapy.
INTRODUCTION AND OBJECTIVES Cardiac resynchronization therapy is associated with improved quality of life and reduced morbidity and mortality in patients with severe ventricular dysfunction and wide QRS. However, its role in the reduction of ventricular arrhythmias is more controversial. METHODS We compared the incidence of ventricular arrhythmias in patients who were undergoing cardiac resyn...
متن کاملSympathetic control after cardiac resynchronization therapy: responders versus nonresponders.
Cardiac resynchronization therapy (CRT) decreases muscle sympathetic nerve activity (MSNA) in patients with severe congestive heart failure (CHF) and cardiac asynchrony. Whether this affects equally patients who clinically respond or not to CRT is unknown. We tested the hypothesis that the favorable effects of CRT on MSNA disappear on CRT interruption only in those who respond to CRT. Twenty-th...
