作者报告应用球囊瓣膜成形术治疗9例钙化性主动脉瓣狭窄的经验。使用球囊直径8～25mm,长3或5cm的聚乙烯9F球囊导管。术时从小到大使用不同球囊直径的导管,经股动脉送入,使不透X线的球囊标志位于钙化的主动脉瓣两侧,然后充盈扩张。术前术后测压力、心排血量以判定效果。大多数病人进行3次以上扩张,每次持续5～8秒。作者见到,该组病例最大主动脉瓣压术前为68±8mmHg,术后降至35±5mmHg,平均主动脉瓣压差自57±7mmHg降至30±5mmHg,心排血量自3.4±0.2L/分增至4.1±0.3L/分,主动脉瓣口面积自0.42±0.04cm~2增至0.81±0.06cm~2。多数病例术后血流动力学改善可同主动脉瓣人工瓣膜置换 The authors report the experience of using balloon valvuloplasty in the treatment of 9 patients with calcific aortic stenosis. A polyethylene 9F balloon catheter with a balloon diameter of 8-25 mm and a length of 3 or 5 cm was used. From small to large intraoperative use of different balloon diameter catheter, the femoral artery into the radio-opaque balloon markers located on both sides of calcified aortic valve, and then filling the expansion. Preoperative and postoperative pressure measurement, cardiac output to determine the effect of. Most patients for more than 3 times to expand, each lasting 5 to 8 seconds. The authors saw that the maximal aortic valvuloplasty in this group was 68 ± 8 mmHg before surgery and decreased to 35 ± 5 mmHg after surgery. The mean aortic valve pressure drop was reduced from 57 ± 7 mmHg to 30 ± 5 mmHg and the cardiac output was 3.4 ± 0.2L / min to 4.1 ± 0.3L / min, and the aortic valve area increased from 0.42 ± 0.04cm ~ 2 to 0.81 ± 0.06cm ~ 2. In most cases, hemodynamic improvement can be replaced with aortic valve prosthesis
