mitral stenosis

基本解釋

The interval between S2 and the OS is related to the severity of mitral stenosis. The more severe the stenosis, the shorter the S2-OS interval.
S2和開瓣音間隔時(shí)間跟二尖瓣狹窄程度有關(guān)，狹窄越嚴(yán)重，S2-OS間期就越短。
Objective:To observe whether percutaneous transluminal ballonmitral valvuloplasty (PTBMV) can improve the pulmonary function of patients with single mitral stenosis (MS).
目的：觀察單純二尖瓣狹窄（MS）患者接受經(jīng)皮腔內(nèi)球囊二尖瓣成形術(shù)（PTBMV）治療前後的肺功能指標(biāo)的變化。

The authors conclude that the method is safe, non invasive, accurate and repeatable, and it can really reflect the flow field uniformity of normal persons and patients with mitral stenosis.
該方法具有安全無創(chuàng)、準(zhǔn)確可靠及可重複性強(qiáng)等優(yōu)點(diǎn)，能如實(shí)地反映正常人及二尖瓣狹窄患者二尖瓣下遊流場均勻性的優(yōu)劣狀況。
