Aortic valve-sparing root replacement (AVSRR) is a technically demanding procedure. In experienced centers it offers excellent short- and long-term results, making the procedure an attractive alternative for aortic root replacement especially in young patients. The aim of this study was to analyze long-term results of AVSRR using the David operation in our institution over the last 25 years.
This is a single-center retrospective analysis of outcomes of David operations performed in a teaching institution not running a large AVSRR-program. Pre-, intra- and postoperative data were collected from the institutional electronic medical record system. Follow-up data were collected through direct contact of the patients and their cardiologists/primary care physicians.
Between 02/1996 and 11/2019, 131 patients underwent David operation in our institution by a total of 17 different surgeons. Median age was 48 (33-59), 18% were female. Elective surgery was performed in 89% of the cases, 11% were operated as emergency in the setting of an acute aortic dissection. Connective tissue disease was present in 24% and 26% had a bicuspid aortic valve. At hospital admission 61% had aortic regurgitation grade ≥3, 12% were in functional NYHA-class ≥III. 30-day mortality was 2%, 97% of the patients were discharged with aortic regurgitation ≤2. In 10-year follow-up, 15 (12%) patients had to be re-operated because of root-related complications. Seven patients (47%) received a transcatheter aortic valve implantation, 8 (53%) required surgical replacement of the aortic valve or a Bentall-De Bono operation. Estimated reoperation-free survival at 5 and 10 years was 93.5% ± 2.4% and 87.0% ± 3.5%, respectively. Subgroup analysis showed no differences in reoperation-free survival for patients presenting with a bicuspid valve or preoperative aortic regurgitation ≥3. However a preoperative left ventricular end diastolic diameter of ≥5.5 cm was associated with worse outcome.
David operations can be performed with excellent perioperative and 10-year follow-up outcomes in centers not running large AVSRR-programs.
保留主动脉瓣的根部置换术（AVSRR）是一项技术要求很高的手术。在经验丰富的中心，该手术能带来出色的短期和长期效果，使其成为主动脉根部置换术颇具吸引力的替代方案，尤其是对于年轻患者。本研究的目的是分析过去25年里我们机构采用大卫手术进行AVSRR的长期效果。
这是对一家未开展大型AVSRR项目的教学机构中进行的大卫手术结果的单中心回顾性分析。术前、术中和术后数据均从机构电子病历系统中收集。随访数据通过直接联系患者及其心脏病专家/初级保健医生来收集。
1996年2月至2019年11月期间，我们机构共有17位不同的外科医生为131例患者实施了大卫手术。患者中位年龄为48岁（33 - 59岁），女性占18%。89%的病例为择期手术，11%是在急性主动脉夹层情况下作为急诊进行手术。24%的患者存在结缔组织病，26%有二叶式主动脉瓣。入院时，61%的患者主动脉反流分级≥3级，12%的心功能纽约心脏协会（NYHA）分级≥III级。30天死亡率为2%，97%的患者出院时主动脉反流≤2级。在10年随访中，15例（12%）患者因根部相关并发症需要再次手术。7例（47%）患者接受了经导管主动脉瓣植入术，8例（53%）需要进行主动脉瓣手术置换或Bentall-De Bono手术。5年和10年的无再次手术生存率估计分别为93.5%±2.4%和87.0%±3.5%。亚组分析显示，二叶式瓣膜患者或术前主动脉反流≥3级的患者在无再次手术生存率方面无差异。然而，术前左心室舒张末期直径≥5.5 cm与较差的预后相关。
在未开展大型AVSRR项目的中心，大卫手术可取得出色的围手术期和10年随访结果。
