Three different techniques for percutaneous balloon aortic valvuloplasty h have been described: retrograde single balloon, retrograde double balloon, and antegrade techniques. This report describes our experience using the three techniques in twenty-five consecutive procedures. All techniques resulted in a significant decrease in transvalvular pressure gradient and an increase in calculated aortic valve area, without significant difference among the three. There was no increase in the degree of aortic regurgitation after valvuloplasty by any of the techniques. Vascular complications occurred only with the retrograde double balloon technique. Cardiac tamponade during balloon inflation occurred with both the retrograde single and double balloon techniques. Three deaths occurred; two during the antegrade technique and one after the retrograde double balloon technique. Thus, balloon aortic valvuloplasty can be effectively performed using any of the three techniques. However, the differing techniques have inherent advantages in specific situations, as well as potential complications.
逆行单气囊、逆行双气囊和顺行技术。本报告描述了我们在连续25例手术中使用这三种技术的经验。所有技术均导致跨瓣压差显著降低，计算的主动脉瓣面积增加，三种技术之间无显著差异。任何一种技术进行瓣膜成形术后主动脉瓣反流程度均未增加。血管并发症仅发生于逆行双气囊技术。逆行单气囊和双气囊技术在气囊扩张时均发生心脏压塞。发生了3例死亡；2例死于顺行技术，1例死于逆行双气囊技术后。因此，使用这三种技术中的任何一种均可有效进行气囊主动脉瓣成形术。然而，不同技术在特定情况下有其固有优势，也有潜在并发症。
