本文报告应用国产球囊导管对5例风湿性二尖瓣狭窄病例实行经皮穿刺单球囊二尖瓣成形术的治疗效果,手术后二尖瓣口面积分别由1.33,1.05,0.95,0.90及1.07cm~3扩张至2.47,1.52,2.15,1.60及1.92cm~2;跨二尖瓣压力阶差也分别由1.73,0.93,2.79,3.06及2.93kPa(13.0,7.0,21.0,23.0及22.0mmHg)降至0,0.13,0.27,0.13及1.06kPa(0,1.0,2.0,1.0及8.0mmHg);舒张期杂音由Ⅲ～Ⅳ级减至0～Ⅱ级,自觉症状及心功能均明显改善。作者认为,应用国产球囊导管,适当地简化手术程序,经皮穿刺球囊二尖瓣成形术可以安全地在有条件的基层医院开展。
This article reports the application of domestic balloon catheter in 5 cases of rheumatic mitral stenosis percutaneous balloon mitral valvuloplasty, the mitral valve area after surgery were 1.33,1.05,0.95,0.90 and 1.07 cm ~ 3 to 2.47, 1.52, 2.15, 1.60, and 1.92 cm ~ 2 respectively; and the pressure gradient across the mitral valve was also increased from 1.73, 0.93, 2.79, 3.06 and 2.93 kPa (13.0,7.0,21.0,23.0 and 22.0 mmHg, ) Decreased to 0, 0.13, 0.27, 0.13 and 1.06 kPa (0, 1.0, 2.0, 1.0 and 8.0 mmHg); diastolic murmur decreased from grade Ⅲ to grade 0 to grade Ⅱ, and both symptoms and cardiac function improved significantly. The author believes that the application of domestic balloon catheter, the appropriate simplification of surgical procedures, percutaneous balloon mitral valvuloplasty can be safely carried out in the conditional primary hospital.
