Comparison of results of percutaneous double balloon mitral valvotomy with open surgical valvotomy. The results in 85 patients with mitral stenosis who had successful balloon mitral valvotomy, using 20 + 20 mm diameter balloon catheters, were compared with the results achieved in a group of 85 patients who had elective open mitral valvotomy. Both groups were of similar age. The mean mitral valve area increased from 0.9 +/- 0.2 to 2.0 +/- 0.3 cm2 (p less than 0.001) after balloon valvotomy. The mean mitral valve area increased from 0.9 +/- 0.3 to 2.2 +/- 0.6 cm2 (p less than 0.001) following surgical open valvotomy. Overall, results of balloon mitral valvotomy are comparable to open surgical mitral valvotomy.
经皮双球囊二尖瓣成形术与直视外科二尖瓣成形术结果比较。对85例二尖瓣狭窄患者采用直径20 + 20 mm球囊导管成功进行球囊二尖瓣成形术的结果，与85例择期直视二尖瓣成形术患者的结果进行比较。两组年龄相似。球囊瓣膜成形术后二尖瓣平均瓣口面积从0.9±0.2增加至2.0±0.3 cm²（p<0.001）。直视外科瓣膜成形术后二尖瓣平均瓣口面积从0.9±0.3增加至2.2±0.6 cm²（p<0.001）。总体而言，球囊二尖瓣成形术的结果与直视外科二尖瓣成形术相当。
