Truncal valve insufficiency has been a significant short- and long-term risk factor for repair of truncus arteriosus. Recent reports have documented the virtues of truncal valve repair. The purpose of this report is to review our experience with truncal valve repair and illustrate our techniques.
Between 1995 and 2000, 8 patients had interventions for severe truncal valve insufficiency at primary repair (3 patients) or in conjunction with conduit replacement (5 patients). One neonate had truncal valve replacement at initial repair early in the experience. The other 7 patients had truncal valve repair, 3 by valvar suture techniques. The remaining 4 patients had leaflet excision and annular remodeling in 3 (coronary reimplantation was required in 2) and commissure resuspension in 1 patient.
Trivial to mild truncal valve insufficiency is present in the patients who had leaflet excision and annular remodeling (n = 3) and commissure resuspension (n = 1). Of the 3 patients who had valvar suture truncal valve repair, there was one death and 2 patients required acute valve replacement. The 7 survivors are doing well 1 month to 6 years postoperatively.
Truncal valve repair by valvar suture techniques has not been successful in our practice. Truncal valve remodeling by leaflet excision and reduction annuloplasty is an effective method for truncal valve repair. When leaflet excision of a coronary sinus of Valsalva is required, coronary artery translocation can be accomplished.
动脉干瓣膜关闭不全一直是动脉干畸形矫治术重要的短期和长期风险因素。近期报告记录了动脉干瓣膜修复的优点。本报告旨在回顾我们在动脉干瓣膜修复方面的经验并阐述我们的技术。
1995年至2000年间,8例患者在初次矫治术时(3例)或在更换管道时(5例)对严重的动脉干瓣膜关闭不全进行了干预治疗。在经验积累初期,1例新生儿在初次矫治术时进行了动脉干瓣膜置换。其他7例患者进行了动脉干瓣膜修复,其中3例采用瓣膜缝合技术。其余4例患者中,3例进行了瓣叶切除和瓣环重塑(2例需要冠状动脉再植),1例进行了瓣叶连合部悬吊术。
进行瓣叶切除和瓣环重塑的患者(n = 3)以及瓣叶连合部悬吊术的患者(n = 1)存在轻微至轻度的动脉干瓣膜关闭不全。在3例采用瓣膜缝合技术进行动脉干瓣膜修复的患者中,1例死亡,2例患者需要紧急瓣膜置换。7名幸存者术后1个月至6年情况良好。
在我们的实践中,采用瓣膜缝合技术进行动脉干瓣膜修复未获成功。通过瓣叶切除和缩窄瓣环成形术进行动脉干瓣膜重塑是一种有效的动脉干瓣膜修复方法。当需要切除主动脉窦瓣叶时,可以完成冠状动脉移位。
