Since the introduction of the aortoventriculoplasty procedure by Konno in 1975, 16 patients have undergone aortic root augmentation by this method at the Woodruff Medical Center of Emory University. In four patients bioprosthetic valve degeneration 2 to 5 years after the Konno procedure has necessitated repeat operation and replacement of the prosthetic aortic valve. Modification of the septal patch or repeat right ventriculotomy has not been required. One patient required an additional lateral anulus-enlargement procedure (Manouguian) whereas the other three have demonstrated stability or growth of the aortic anulus. We have not observed recurrent subvalvular stenosis or problems with the right ventricular outflow tract. Repeat operation after aortoventriculoplasty has been relatively simple and has usually involved only the supra-annular aorta.
自1975年Konno引入主动脉心室成形术以来，在埃默里大学伍德拉夫医学中心，已有16例患者通过该方法进行了主动脉根部扩大术。4例患者在Konno手术后2至5年出现生物人工瓣膜退变，需要再次手术并更换人工主动脉瓣膜。无需对间隔补片进行修改或再次进行右心室切开术。1例患者需要额外进行外侧瓣环扩大术（马努吉安手术），而其他3例患者的主动脉瓣环显示稳定或增大。我们未观察到瓣下狭窄复发或右心室流出道问题。主动脉心室成形术后的再次手术相对简单，通常仅涉及瓣环上方的主动脉。
