Abstract:
Objective To evaluate the cardiac hemodynamics and function before and after balloon pulmonary angioplasty ( BPA ) treatment in patients with chronic thromboembolic pulmonary hypertension ( CTEPH) using echocardiography ,and to discuss the clinical value of the treatment . Methods A total of 36 CT EPH patients with medium‐high risk stratification underwent BPA during the period of September 2016 to January 2019 in Beijing Chao‐Yang Hospital ,Capital M edical University were recruited . T he following conventional echocardiographic parameters including right ventricular basal diameter ( RVD ) ,left ventricular basal diameter ( LVD) ,right atrial diameter ( RAD) ,left atrial diameter ( LAD) ,main pulmonary artery diameter ( DM PA ) , left ventricular eccentricity index ( LVEI ) , left ventricular ejection fraction ( LVEF) and pulmonary artery systolic pressure ( PASP ) were recorded .Echocardiographic parameters of right ventricular ( RV ) function including tricuspid annular plane systolic excursion ( T APSE ) , right ventricular fractional area change ( RVFAC ) ,tissue Doppler – derived tricuspid lateral annular systolic velocity ( S′) ,RV index of myocardial performance ( RIM P ) and right ventricular free wall longitudinal strain ( GLS) were measured . T he patients were divided into 2 groups according to the threshold value of postoperative SPAP of 50 mmHg (group Ⅰ :SPAP ≤ 50 mmHg ,group Ⅱ :SPAP＞50 mmHg) . Changes between each parameter before and after BPA were analyzed . Results ① T he frequency of BPA treatment for CT EPH patients ranged from 1 to 6 times . After BPA treatment ,SPAP decreased significantly ,and the measurements of RV function including T APSE ,RVFAC ,RIM P and GLS improved significantly ( all P ＜0 .05) . ②Patients in group Ⅰ showed significantly better RV function including T APSE ,RVFAC and GLS compared with group Ⅱ before BPA ( P ＜0 .05) . ③Univariate logistic regression showed that parameters of preoperative RV function T APSE , RVFAC and GLS had certain effects on the curative effect of interventional surgery . Conclusions Echocardiography can evaluate the hemodynamics and RV function in CT EPH patients with BPA .After BPA ,pulmonary artery pressure decreases and RV function improves to some extent ,suggesting that the treatment of BPA has certain clinical application and popularization value .
