经皮球囊二尖瓣成形术13例报告

Percutaneous Balloon Mitral Valvuloplasty:Report of 13 Cases

应用经皮球囊二尖瓣成形术治疗13例风心二尖瓣狭窄病人。术前、后的左房平均压,二尖瓣压力阶差,二尖瓣口面积分别为2.7l±0.42kPa,2.64±0.43kPa,0.99±0.14(cm^2)和1.14±0.38kPa,0.81±0.47kPa,2.02±0.50(cm^2)。P值均<0.001。随访2周至36个月,心功能持续改善。与外科分离术相比,本术创伤小,痛苦小,相对安全,疗效高,康复快,并可反复进行,是一种有希望的非外科手术疗法,值得推广应用。

Percutaneous balloon mitral vaivuloplasty was done on 13 patients with rheumatic mitral stenosis. Changes observed after the treatment included a decrease in mean left atrial pressure from 2. 71±0. 42kPa to 1. 14±0. 38kPa (P<0. 001), a decrease in trans- mitral gradient from 2. 64±0. 43kPa to 0. 81±0. 48kPa (P<0. 001), and an increase in the area of mitral orifice from 0. 99±0. 14cm^2 to 2. 02±0. 50cm^2(P<0. 001). The patients were followed up for 2 to 36 months and the improvement in their cardiac function was steady and persistent. When compared with the surgical therapy, this procedure is promising and wor- thy of recommendation on account of its relative safety, quick recovery, and less trauma.
