In order to evaluate the short- and mid-term results of percutaneous aortic balloon valvuloplasty, 40 consecutive elderly patients, who had undergone balloon valvuloplasty for calcific aortic stenosis, were prospectively followed up by means of clinical and echo-Doppler examinations. Although valvuloplasty often dramatically improves hemodynamics and relieves symptoms, these benefits seem to be short-lived in most cases. Restenosis, defined as a loss of 50% or more of the increase in aortic valve area obtained by the dilatation, has a very high rate of occurrence. Aortic balloon valvuloplasty should therefore be reserved for truly inoperable cases and can be performed in hemodynamically unstable patients, who may later undergo surgery.
为了评估经皮主动脉球囊瓣膜成形术的短期和中期结果，对40例因钙化性主动脉瓣狭窄接受球囊瓣膜成形术的老年患者进行了前瞻性临床和超声多普勒随访检查。尽管瓣膜成形术通常能显著改善血流动力学并缓解症状，但在大多数情况下这些益处似乎是短暂的。再狭窄定义为扩张后获得的主动脉瓣面积增加量减少50%或更多，其发生率非常高。因此，主动脉球囊瓣膜成形术应仅用于真正无法手术的病例，并且可以在血流动力学不稳定的患者中进行，这些患者随后可能接受手术。
