摘要
经皮二尖瓣球囊成形术治疗二尖瓣狭窄67例,63例成功(94%),术后左房平均压由24+8mmHg 降至15+7mmHg(P<0.001);跨瓣压差由21±9mmhg 降至10±8mmhg(P<0.001);左房内径由49±7mmhg 降至43±7mmhg(P<0.001)二尖瓣口面积由1.1cm±0.2cm 增至2.1cm±0.3cm(P<0.001);心输出量由5.7±1.4升/分增至6.3±1.6升/分(P<0.001)。MR 系影响 PTMV 术的效果的重要因素,术中产生 MR 主要决定二尖瓣病理形态结构,与采用球囊类型无关。术后近期及远期疗效稳定。国产球囊可与进口球囊相媲美。
From March 1993,to December 1995,percutaneous balloon mitral valvuloplasty (PBMV)was performed in 67 patients(mean age 41±8years)with rheumatic mitral stenosis by Jnane balloon catheter and domeatic balloon catheter outcoming in successful results in 63 patients(94%). After PTMV,there were some significant improvements in mean left atrial pressure(24+8mmHg to 15+ 7mmHg,P<0.001),mitral gradient (21±9mmHg to 10±8mmHg,P<0.001),left atrial dimen- sions(49±5mmHg to 43+7mmHg,P<0.001),mitral valre area(1.1±0.2cn to 2.1±0.3cm,P <0.001),and cardiac output(5.7±1.41/min to 6.3±1.61/min,P<0.001).Severe regurgitations (MR)were noted in three patients(5%),One with mitral valve replacement becauce of clinical dete- rioration,So the real cause was due to the valvular morphological deformity,PTMV using domestic balloon cathetor showed no difference to the Inoue balloon catheter.The dilatation effect shoned to be guite ideal for short and long-term improvement in symptoms.
