Abstract：Objective To evaluate the early effect of cardiac resynchronization therapy (CRT)on right heart functions in patients with heart failure (HF).Methods Forty three patients with HF undergoing CRT from Juanary 2005 to November 2013were enrolled.Before and 1 week after CRT,the right ventricular diameter (RVD),right atrial area (RAA),tricuspid annular plane systolic excursion (TAPSE),area of tricuspid regurgitation (TRA) and systolic pulmonary artery pressure (SPAP) were measured by echocardiography to analyze the right heart function.Results The triple chamber pacemakers were successfully implanted in all the patients.After CRT,RAA and TRA were significantly decreased compared with those before CRT [(17 ± 6)cm2 vs (18 ± 7) cm2,(2.4±1.9) cm2 vs (3.2±2.1) cm2] (P＜0.05);theTAPSE and SPAPwere improved[(12.9± 2.8) mmvs (11.6±2.6) mm,(32±10) mmHg vs (37±15) mmHg](P＜0.01).Conclusion The right heart function can be improved in an early stage after CRT in HF patients.
