The renewed interest in mitral valve replacement with a pulmonary autograft encouraged us to perform this procedure in selected patients.
From August 2000 to February 2002, 10 patients between 30 and 52 years of age with calcific mitral valvular disease underwent the Ross II procedure. Patients were either in New York Heart Association functional class III (7/10) or IV (3/10). Transthoracic echocardiography was done in all the patients to confirm the diagnosis. A pulmonary autograft was used to replace the diseased mitral valve. Intraoperative transesophageal echocardiography confirmed normal functioning of the autograft. There were 2 early deaths. The 8 survivors are in New York Heart Association functional class I with excellent autograft and homograft function at a follow-up of 2-20 months (mean 9 months).
This procedure is a viable option for mitral valve replacement in patients with calcific mitral valve disease. However, the procedure is technically demanding and requires a valve bank.
对使用肺动脉自体移植物进行二尖瓣置换术的重新关注促使我们在选定的患者中开展该手术。
2000年8月至2002年2月，10例年龄在30至52岁之间的钙化性二尖瓣疾病患者接受了Ross II手术。患者均为纽约心脏协会心功能分级III级（7/10）或IV级（3/10）。所有患者均进行了经胸超声心动图检查以确诊。使用肺动脉自体移植物替换病变的二尖瓣。术中经食管超声心动图证实自体移植物功能正常。有2例早期死亡。8名幸存者为纽约心脏协会心功能分级I级，在2至20个月（平均9个月）的随访中，自体移植物和同种异体移植物功能良好。
对于钙化性二尖瓣疾病患者，该手术是二尖瓣置换的一种可行选择。然而，该手术技术要求高，且需要瓣膜库。
