Valve-sparing aortic root replacement remains challenging for patients with eccentric severe aortic regurgitation when the cusps are totally asymmetric. We report a case of successful reimplantation operation for such a lesion. Because free margin lengths from commissure to Arantius body of the adjacent two cusps were matched while inter-commissural distances were totally different, right coronary cusp prolapse was corrected by asymmetrically aligning the position and height of three commissures without cusp plication.
对于伴有严重偏心性主动脉瓣反流且瓣叶完全不对称的患者，保留瓣膜的主动脉根部置换术仍然具有挑战性。我们报告了一例针对此类病变成功进行再植入手术的病例。由于相邻两个瓣叶从瓣叶联合处到瓣叶小结的游离缘长度匹配，而瓣叶联合间距离完全不同，通过不对称地调整三个瓣叶联合的位置和高度而不进行瓣叶折叠，纠正了右冠状动脉瓣叶脱垂。
