An 86-year-old lady with recurrent admissions for heart failure due to a severely regurgitant aortic bioprosthesis (SJM Epic 19 mm) was not a candidate for re-operation due to age and frailty. Her small ilio-femoral arteries precluded a transfemoral transcatheter valve-in-valve (VIV) approach. The small internal diameter of her bioprosthesis (16 mm) forbids the implantation of the smallest available transapical transcatheter heart valve (THV). We, therefore, decided to perform a first-in-human transapical aortic VIV implantation using a 20 mm balloon expandable THV and a transfemoral delivery system. The procedure was successfully performed under general anesthesia, without any contrast dye and under fluoroscopy as well as transesophageal echocardiography guidance. The post-procedural transvalvular gradient was 15 mm Hg (pre-procedural 14 mm Hg). At 30-day follow-up, the lady was living independently at home without shortness of breath during her daily activities. If redo-surgery for prosthetic regurgitation is not an option, VIV implantation in very small surgical bioprosthesis is feasible and leads to acceptable hemodynamics and clinical improvement.
一位 86 岁的老年女性因严重反流的主动脉生物瓣(SJM Epic 19 毫米)而反复出现心力衰竭,由于年龄和虚弱,她不适合再次手术。她的小股-股动脉不适合经股经导管瓣中瓣(VIV)方法。她的生物瓣(16 毫米)内径较小,不允许植入最小可用的经心尖经导管心脏瓣膜(THV)。因此,我们决定使用 20 毫米球囊可扩张 THV 和经股输送系统进行首例人体经心尖主动脉 VIV 植入。该手术在全身麻醉下成功进行,无需任何造影剂,并在透视和经食管超声心动图引导下进行。术后跨瓣梯度为 15mmHg(术前为 14mmHg)。在 30 天随访时,这位女士在家中独立生活,日常活动中没有呼吸困难。如果再次手术治疗假体反流不可行,那么在非常小的外科生物瓣中植入 VIV 是可行的,并且可以导致可接受的血液动力学和临床改善。
