Abstract:
Objectives:To evaluate the tricuspid valve(TV)geometric remodeling in patients with idiopathic pulmonary arterial hypertension(IPAH)by three-dimensional transthoracic echocardiography. Methods:Two-dimensional and three-dimensional transthoracic echocardiography were performed in 30 IPAH patients and 15 healthy controls,and the geometry parameters of TV were obtained by four-dimensional auto tricuspid valve quantitative(4D Auto-TVQ)in the right ventricular-focused apical view.Pulmonary arterial hypertension was determined by right heart catheterization within 48 hours of echocardiography. Results:The 4-chamber diameter,tricuspid annular(TA)perimeter,TA area,maximal tenting height,coaptation point height and tenting volume were larger in IPAH patients than those in healthy controls(all P＜0.05),2-chamber diameter was similar between two groups.In IPAH group,maximal tenting height and coaptation point height were moderately correlated with right ventricular end-diastolic volume(r=0.710,r=0.515,both P＜0.05),while TA perimeter,4-chamber diameter and TA area were moderately correlated with right atrial end-systolic volume(r=0.712,r=0.558,r=0.545,all P＜0.05). Conclusions:IPAH patients have larger maximal tenting height,coaptation point height and tenting volume,TA enlargement is mainly visible in 4-chamber diameter.TV tenting height is associated with right ventricular volume,but TA size is associated with right atrial volume in IPAH patients.
