Mechanism Study of Effects of the Intrathoracic Pressure on the Velocity of Tricuspid Regurgitation(TR) and Estimation of Pulmonary Artery Pressure 胸压对三尖瓣反流(TR)速度和肺动脉压测定影响的机制研究
The blood flow increases with the increment of the compression degree when heart rate and the blood pressure range at the near end are invariable. Mitral and tricuspid regurgitation were much milder in group CP than that in group CP. 心率和近段血压范围不变时,流量随着收缩程度的增加而增加。收缩期CP组二尖瓣、三尖瓣反流(TR)发生率明显低于RCM组,且程度较轻;
Evaluation of Tricuspid Valve Repair With Flexible Ring Annuloplasty in Patients With Acquired Valvular Heart Disease Echocardiography demonstrated tricuspid chordae tendinae rupture with remarkable tricuspid regurgitation. 成形软环应用于三尖瓣关闭不全修复的疗效评价心脏超音波证实三尖瓣腱索断裂及明显的三尖瓣逆流。
Determinants of Mid-Term Outcomes of Tricuspid Annuloplasty for Functional Tricuspid Regurgitation(TR) Mitral and tricuspid regurgitation were much milder in group CP than that in group CP. 三尖瓣成形术治疗功能性三尖瓣反流(TR)的中期疗效及影响因素收缩期CP组二尖瓣、三尖瓣反流(TR)发生率明显低于RCM组,且程度较轻;
Mitral and tricuspid regurgitation were much milder in group CP than that in group CP. The weight of ventricular blood forces up the cusps of the tricuspid. valve, so that blood cannot flow back. 收缩期CP组二尖瓣、三尖瓣反流(TR)发生率明显低于RCM组,且程度较轻;心室内血液的压力把三尖瓣的各尖瓣举向上方,使血液不能逆流。
