Transcatheter aortic valve replacement (TAVR) has recently become a suitable alternative for treatment of symptomatic aortic stenosis in patients who are at very high risk for morbidity and mortality with conventional corrective surgery. In the fall of 2011, the Food and Drug Administration approved the use of TAVR, allowing for reimbursement at institutions outside of investigative trials. We report the initiation of a TAVR-based program at an academic tertiary care facility that did not participate in the Placement of Aortic Transcatheter Valves (PARTNER) 1 or PARTNER II trials.
A total of 160 patients were evaluated for TAVR from May 2012 through June 2013. Transcatheter aortic valve replacement was found to be appropriate for 50 (31%).
In this experience, morbidity and mortality were similar to those reported for the PARTNER trial (30-day hospital mortality was 8%). A single case of presumed cerebrovascular accident was observed. These results demonstrate that the real-world application can be done with comparable results. Implementation of lessons learned in the trials allowed a very short learning curve and excellent results after only a limited number of patients. Use of computed tomography reconstructed images for operative planning, including fluoroscopic angle, facilitated minimal use of contrast in each case.
Transcatheter aortic valve replacement is a viable option for patients at very high risk for surgical intervention in the post-Food and Drug Administration approval era. Real-world results comparable with published outcomes from experienced centers involved in the PARTNER trial can be achieved.
经导管主动脉瓣置换术(TAVR)最近已成为治疗有症状主动脉瓣狭窄患者的一种合适替代方法,这些患者接受传统矫正手术时发生发病和死亡的风险非常高。2011年秋季,美国食品药品监督管理局批准了TAVR的使用,允许在非研究性试验机构进行报销。我们报告了在一家未参与主动脉经导管瓣膜置入(PARTNER)1或PARTNER II试验的学术三级医疗中心启动基于TAVR的项目情况。
从2012年5月至2013年6月,共有160例患者接受了TAVR评估。发现50例(31%)患者适合经导管主动脉瓣置换术。
在本次经验中,发病率和死亡率与PARTNER试验报告的相似(30天住院死亡率为8%)。观察到1例疑似脑血管意外病例。这些结果表明,现实世界中的应用可以取得可比的结果。吸取试验中的经验教训使得学习曲线非常短,仅在有限数量的患者之后就取得了优异的结果。使用计算机断层扫描重建图像进行手术规划,包括透视角度,有助于在每个病例中尽量减少造影剂的使用。
在食品药品监督管理局批准时代,经导管主动脉瓣置换术对于手术干预风险非常高的患者是一种可行的选择。可以取得与参与PARTNER试验的经验丰富中心公布的结果相当的现实世界结果。
