Echocardiographic measures of acute haemodynamic response after cardiac resynchronization therapy predict long-term clinical outcome.
AIMS Although acute haemodynamic improvement in response to cardiac resynchronization therapy (CRT) is reflective of a favourable cardiac contractile response, there is limited information regarding not only its ability to predict long-term clinical outcome but also cardiac-substrate-specific differences in the prognostic value of this measure. METHODS AND RESULTS Fifty-three heart failure pa...
متن کاملSeeing is believing: acute haemodynamic response to predict long-term outcome in cardiac resynchronization therapy.
Many heart failure specialists still believe that the pathophysiology of cardiac resynchronization therapy (CRT) is incompletely understood; however, it must be emphasized that the main effects of biventricular pacing have already been described more than a decade ago. In 1994, Cazeau et al. reported how biventricular pacing improves clinical signs and symptoms of heart failure, acutely increas...
متن کاملOver-time mitral regurgitation changes following cardiac resynchronization therapy.
PURPOSE Mitral regurgitation (MR) is a leading cause of mortality in patients with heart failure (HF). Cardiac resynchronization therapy (CRT) has been shown to improve MR in these patients, but maintenance of MR improvement after CRT implantation has not yet been evaluated. We aimed to evaluate the post-CRT improvement pattern of MR in a 6-month follow-up period. MATERIALS AND METHODS 65 con...
متن کاملHemodynamic changes during cardiac resynchronization therapy.
Cardiac resynchronization therapy (CRT) is a new method for the correction of inter- and/or intraventricular conduction delays of patients with heart failure. The long-term impact of CRT on central hemodynamics is not fully characterized. We performed complete right heart catheterization studies in 31 patients receiving a CRT device pre and 6 months after implantation. Most of the patients impr...
متن کاملMitral-Aortic Flow Reversal in Cardiac Resynchronization Therapy
Flow entering the left ventricle (LV) is redirected to the outflow tract without reaching the apex. This 180° reversal in flow direction is because of the presence of a vortex ring, a structure of rotating flow generated around the mitral valve (Figure 1). This pattern in flow dynamics has been proposed to contribute to early systole through the facilitation in early ejection of a fluid already...
