Cardiac resynchronization therapy: relevance of right ventricular function evaluation.
Heart failure constitutes one of the major public health problems with an incidence that approaches 10 per 1000 population after 65 years of age. The majority of clinical trials have focused mostly on left ventricular (LV) failure and have led to established therapeutic approaches that are included in the current guidelines. In contrast, right ventricular (RV) failure is poorly understood and i...
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 کاملRight ventricular function, pulmonary pressure estimation, and clinical outcomes in cardiac resynchronization therapy.
BACKGROUND Right ventricular function (RVF) is an important determinant of outcome in patients with heart failure, and those with severe RV dysfunction have worse outcome after cardiac resynchronization therapy (CRT). We used data from the Multicenter Automatic Defibrillator Implantation Trial with Cardiac Resynchronization Therapy (MADIT-CRT) Trial to determine whether therapy with CRT is infl...
متن کاملLeft ventricular systolic torsion correlates global cardiac performance during dyssynchrony and cardiac resynchronization therapy.
Left ventricular (LV) systolic torsion is a primary mechanism contributing to stroke volume (SV). We hypothesized that change in LV torsion parallels changes in global systolic performance during dyssynchrony and cardiac resynchronization therapy (CRT). Seven anesthetized open chest dogs had LV pressure-volume relationship. Apical, basal, and mid-LV cross-sectional echocardiographic images were...
متن کاملRight Atrial Pacing Impairs Cardiac Function During Resynchronization Therapy
OBJECTIVES We aimed to compare the hemodynamic effects of right-atrial-paced (DDD) and right-atrialsensed (VDD) biventricular paced rhythm on cardiac resynchronization therapy (CRT). BACKGROUND Cardiac resynchronization therapy improves hemodynamics in patients with severe heart failure and left ventricular (LV) dyssynchrony. However, the impact of active right atrial pacing on resynchronizatio...
