【摘要】 本文报告经皮球囊二尖瓣成形术治疗二尖瓣狭窄12例。10例术前平均左房压为18mmHg～40mmHg(26.7±7.15mmHg),术后即刻为4mmHg～18mmHg(10.6±3.86mmHg)P<0.01。跨瓣压差术前10mmHg～40mmHg(19.6±9.05mmHg),术后为0～5mmHg(2.65±2.21mmHg)P<0.01。1例失败,1例术后发生二尖瓣关闭不全急性左心衰竭死亡。更多还原

【Abstract】 Twelve patients with mitral stenosis (1 male, 11 female age range 35 to44 years) underwent percutaneous balloon mitral valvuloplasty (PBMV). Meanleft atrial pressure of 10 patients before valvuloplasty ranged from 18 to 40mmHg(mean 26 .7± 7. 15mmHg): It fell to 4-18 mmHg(mean 10 .6 ±3 .86mmHg)immediately after dilation (P<0 .01). Mean gradient across the mitral valvebefore valvuloplasty ranged from 10 to 40 mmHg (mean 19.6± 9 .05mmHg) anddecreased significantly to 0-5mmHg (mean 2 .65± 2 .21mmHg) immediately afterdilation (P<0.01). One patient was failure in percutaneous balloon mitralvalvuloplasty. Another one died from acute left heart failure which was relatedto mitral insufficient.更多还原
