英文摘要: In precapillary pulmonary hypertension (PH) patients, we sought to (1) investigate the relationship between ventricular insertion point (VIP) T1 times, hemodynamic parameters, and biventricular function, and (2) determine the predictors of anterior and inferior VIP T1 time. Twenty-two patients with precapillary PH underwent 1.5-T cardiac MR, right heart catheterization (RHC), and echocardiography. A group of 10 healthy age- and sex-matched volunteers served as controls. Biventricular function, morphology and mass were obtained from short-axis cine images. Native T1 times at anterior, inferior VIP, septum and LV lateral wall were respectively derived from all subjects. Mixed venous oxygen saturation (SvO2) was the strongest hemodynamic parameters correlating with anterior...
