We performed percutaneous double balloon tricuspid valvotomy in four patients (36 +/- 12 years of age), with severe symptomatic rheumatic tricuspid stenosis and mild mitral valve disease. Two 9F Meditech balloon catheters, 15-20 mm diameter, were positioned simultaneously across the tricuspid valve and inflated up to five atmospheres pressure achieving valvotomy. After balloon valvotomy there was symptomatic improvement, and the Doppler tricuspid valve area was increased from a mean of 1 +/- 0.2 to 2.2 +/- 0.2 cm2 (P less than 0.001). At 3-year follow-up the symptomatic improvement persisted and the mean tricuspid valve area was maintained at 2.2 +/- 0.1 cm2. During the follow-up period there was no increase in degree of tricuspid regurgitation assessed by colour Doppler. We conclude that 3 years after balloon valvotomy of the tricuspid valve, the 120% increase in valve area persists, with no objective evidence of restenosis.
我们对4例严重症状性风湿性三尖瓣狭窄合并轻度二尖瓣疾病的患者（年龄36±12岁）实施了经皮双球囊三尖瓣瓣膜切开术。将两根直径15 - 20mm的9F美迪泰克球囊导管同时置于三尖瓣上并充气至5个大气压以完成瓣膜切开术。球囊瓣膜切开术后症状有所改善，多普勒测量的三尖瓣瓣口面积从平均1±0.2cm²增加至2.2±0.2cm²（P＜0.001）。在3年的随访中，症状改善持续存在，平均三尖瓣瓣口面积维持在2.2±0.1cm²。在随访期间，经彩色多普勒评估的三尖瓣反流程度没有增加。我们得出结论，三尖瓣球囊瓣膜切开术后3年，瓣口面积增加120%的情况持续存在，且无再狭窄的客观证据。
