To determine the feasibility of original aortic valve reconstruction, 404 consecutive cases were reviewed. The early results are reported here.
Aortic valve reconstruction was performed for 404 patients from April 2007 through September 2011. The results for all 404 patients were reviewed retrospectively. There were 289 patients with aortic stenosis and 115 patients with aortic regurgitation. One hundred two patients had bicuspid aortic valves, 13 patients had unicuspid valves, and 2 patients had quadricuspid valves. There were 201 males and 203 females. Mean age was 69.0 ± 12.9 years. Preoperative echocardiography revealed an average peak pressure gradient of 79.6 ± 32.5 mm Hg with aortic stenosis. Surgical annular diameter was 20.3 ± 3.2 mm. The surgical procedure is based on the independent tricuspid replacement by autologous pericardium. First, the distance between the commissure is measured with an original sizing apparatus, then the pericardial cusp is trimmed using an original template, and it is sutured to the annulus.
There were no conversions to prosthetic valve replacement. There were 7 in-hospital mortalities resulting from a noncardiac cause. Postoperative echocardiography revealed an average peak pressure gradient of 19.8 ± 10.2 mm Hg 1 week after surgery and 13.8 ± 3.7 mm Hg 3.5 years after surgery. Two patients needed reoperation because of infective endocarditis. The other 402 patients showed less than mild aortic regurgitation. No thromboembolic events were recorded. The mean follow-up period was 23.7 ± 13.1 months. Freedom from reoperation was 96.2% at 53 months of follow-up.
Original aortic valve reconstruction was feasible in patients with various aortic valve diseases. Long-term data will be disclosed in the future.
为了确定主动脉瓣重建的可行性,我们回顾了 404 例连续病例。现将早期结果报告如下。
自 2007 年 4 月至 2011 年 9 月,对 404 例患者进行了主动脉瓣重建。回顾性分析了所有 404 例患者的结果。其中 289 例患者为主动脉瓣狭窄,115 例患者为主动脉瓣关闭不全。102 例患者为二叶式主动脉瓣,13 例患者为单叶式主动脉瓣,2 例患者为四叶式主动脉瓣。201 例为男性,203 例为女性。平均年龄为 69.0±12.9 岁。术前超声心动图显示主动脉瓣狭窄的平均峰值压力梯度为 79.6±32.5mmHg。手术瓣环直径为 20.3±3.2mm。手术方法是基于自体心包的独立三尖瓣置换。首先,使用原始测量仪测量瓣环的距离,然后使用原始模板修剪心包瓣叶,并将其缝合到瓣环上。
无转为机械瓣置换的病例。7 例患者因非心脏原因死亡。术后 1 周和 3.5 年后的超声心动图显示,平均峰值压力梯度分别为 19.8±10.2mmHg 和 13.8±3.7mmHg。2 例患者因感染性心内膜炎需要再次手术。其余 402 例患者的主动脉瓣反流小于轻度。无血栓栓塞事件发生。平均随访时间为 23.7±13.1 个月。53 个月的随访中,无再次手术的生存率为 96.2%。
主动脉瓣重建术在各种主动脉瓣疾病患者中是可行的。我们将在未来公布长期数据。
