Assessment of the right ventricular function after pulmonary thromboendarterectomy by Doppler echocardiography / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the right ventricular function of chronic thromboembolic pulmonary hypertension (CTEPH) after pulmonary thromboendarterectomy (PTE) by Doppler echocardiography. Methods In 16 patients with CTEPH,end-diastolic left ventricular diameter(LVDd), end-diastolic right ventricular areas (RVEDA), end-systolic right ventricular areas (RVESA), right ventricular fractional area change (RVFAC), pulmonary accelerative time (Pact), pressure gradient of tricuspid valve regurgitation (PGT1), area of tricuspid valve regurgitation (AT1) were measured by echocardiography. Results Fifteen and thirty days after surgery,the LVDd and Pact had increased,RVEDA, RVESA,PGT1 and AT1 had decreased while RVFAC had increased in all cases. Conclusions PTE may effectively improve the right ventricular function of patients with CTEPH.
