The Ross procedure has been used increasingly to treat aortic valve disease in children and young adults. The primary indication for the Ross procedure is to provide a permanent valve replacement in children with congenital aortic stenosis. More recently, it has been extended to young adults with a bicuspid aortic valve and small aortic annulus, especially women wishing to have children. Other possible indications include complex left ventricular outflow obstructive disease, native or prosthetic valve endocarditis, and adult aortic insufficiency with a dilated aortic annulus. Conversely, Marfan syndrome is considered to an absolute contraindication, and this procedure should be used with caution in patients with rheumatic valve disease and a dysplastic dilated aortic root because of the higher associated incidence of autograft dysfunction. The technique of total aortic root replacement has become the preferred method of autograft implantation, because it carries the lowest risk of pulmonary autograft failure. In patients with marked graft-host size mismatch, either concomitant aortic annulus reduction and fixation or aortic annulus enlargement (i.e., the Ross-Konno procedure) should be performed. The Ross Procedure International Registry data document that in the modern era (post-1986) the early and late mortality rate is 2.5% and 1%, respectively. Excellent long-term results have been reported, and the benefits of this procedure include optimal hemodynamics, low risk of endocarditis, resistance to infection in patients with active endocarditis, and nonthrombogeneicity and therefore few anticoagulation-related complications. The Ross procedure can be performed with acceptable early and mid-term mortality and excellent autograft durability. Further long-term follow-up will confirm the role of this procedure in patients with various types of aortic valve disease.
罗斯手术越来越多地用于治疗儿童和年轻成人的主动脉瓣疾病。罗斯手术的主要适应证是为先天性主动脉瓣狭窄的儿童提供永久性瓣膜置换。最近,它已扩展到患有二叶式主动脉瓣和小主动脉瓣环的年轻成人,尤其是希望生育的女性。其他可能的适应证包括复杂的左心室流出道梗阻性疾病、自体或人工瓣膜心内膜炎以及伴有主动脉瓣环扩张的成人主动脉瓣关闭不全。相反,马凡综合征被认为是绝对禁忌证,由于自体移植物功能障碍的相关发生率较高,对于风湿性瓣膜病和发育异常的扩张主动脉根部患者,应谨慎使用该手术。全主动脉根部置换技术已成为自体移植物植入的首选方法,因为它导致肺动脉自体移植物失败的风险最低。对于移植物与宿主大小明显不匹配的患者,应同时进行主动脉瓣环缩小和固定或主动脉瓣环扩大(即罗斯 - 康诺手术)。罗斯手术国际注册数据表明,在现代(1986年后),早期和晚期死亡率分别为2.5%和1%。已有报道称该手术长期效果良好,其优点包括最佳的血流动力学、心内膜炎风险低、对活动性心内膜炎患者抗感染、非血栓形成性以及因此抗凝相关并发症少。罗斯手术可以在可接受的早期和中期死亡率以及良好的自体移植物耐久性的情况下进行。进一步的长期随访将证实该手术在各种类型主动脉瓣疾病患者中的作用。
