Abstract:
Objective To investigate the changes of pulmonary capillary wedge pressure(PCWP) before and after off-pump coronary artery bypass graft(OPCABG) using transesophageal echocardiography(TEE). Methods Mitral valve flow(MVF) and pulmonary veinous flow(PVF) were measured in 46 patients before and after OPCAB using TEE and PCWP was detected by cardiac catheter. The correlations between indices derived from TEE and catheterization-measured PCWP and the differences before and after OPCAB were studied. Results There were obvious differences in the indices derived from TEE and PCWP which could reflect the left ventricular function. The most indices measured in PVF and MVF correlated with PCWP(r=(0.30)-(0.76),P
