Echocardiographic changes after cardiac resynchronisation therapy.
BACKGROUND AND AIM The aim of this prospective study was to evaluate echocardiographic changes in clinical responders and nonresponders after 3 and 15 months of cardiac resynchronisation therapy (CRT). METHODS Fifty eight patients in whom a biventricular system was implanted between 2005 and 2008 were followed up at 3 and at 15 months. Clinical and echocardiography parameters including intra-...
متن کاملQRS duration versus morphology and survival after cardiac resynchronization therapy
AIMS The prognostic implications of QRS duration and morphology in heart failure patients treated with cardiac resynchronization therapy (CRT) remains debated. The present evaluation investigated the association between QRS duration (<150 vs. ≥150 ms) and QRS morphology (left bundle brand block [LBBB] vs. non-LBBB) and long-term prognosis of a large cohort of unselected heart failure patients t...
متن کاملAge of cardiac resynchronisation therapy; cardiac resynchronisation therapy in elderly
I have read the article entitled “Is cardiac resynchronisation therapy feasible, safe and beneficial in the very elderly?” by Olechowski, et al. with great interest, recently published in Journal of Geriatric Cardiology. The investigators reported that implantation of cardiac resynchronisation therapy (CRT) is feasible and safe in very elderly despite extensive co-morbidity. I would like to emp...
متن کاملOptimisation of cardiac resynchronisation therapy during exercise
The benefits of cardiac resynchronisation therapy (CRT) in selected cohorts with systolic dysfunction and congestive heart failure are well established [1–3]. CRT reduces heart failure hospitalisations, decreases mortality, and improves the quality of life and cardiac function, described as left ventric-ular (LV) reverse remodelling. CRT improves inter-, intra-and atrio-ventricular dyssynchrony...
متن کاملOCUS ISSUE: CARDIAC RESYNCHRONIZATION THERAPY Normal QRS Duration and Resynchronization
Cardiac resynchronization therapy has been shown to be an effective treatment for patients with systolic ventricular dysfunction, prolonged ( 120 ms) QRS duration, and New York Heart Association (NYHA) functional class III or IV symptoms despite optimal medical therapy. However, studies show that a majority of heart failure patients have QRS duration 120 ms. We have been investigating the poten...
