Left ventricular pseudoaneurysm (LVP) formation is a rare but potentially life-threatening complication of transapical transcatheter aortic valve replacement (TAVR). Conventionally, a pseudoaneurysm has been treated surgically; however, improved transcatheter technique and device technology have made a percutaneous closure of LVP an increasingly viable option, especially in a patient unfavorable for surgery. A TAVR candidate is most likely at increased surgical-risk or inoperable. Therefore a percutaneous closure can be a reasonable strategy for LVP, but its experience following this emerging aortic valve procedure remains limited. We describe a case of LVP formation after TAVR in which it was efficiently treated with a percutaneous closure using a transapical approach via LVP. The first attempt was performed with a transfemoral approach. Pre-closure angiography revealed an eccentric shape of a LVP neck like a "chicken leg". This shape caused serious difficulty to cross LVP with a wire and it was not accomplished. However, the LVP location was at the apex and we could access from a chest wall through the pseudoaneurysm in the second attempt. This approach allowed a close and coaxial wire manipulation and the neck of LVP was finally crossed. After that, a closure device was deployed and the second procedure was successfully completed. An approach selection often contributes to a procedural success. This is the first case of a percutaneous LVP closure following TAVR using a transapical access and may suggest this approach as a possible option for this catheter closure in TAVR candidates. © 2016 Wiley Periodicals, Inc.
左心室假性动脉瘤(LVP)形成是经心尖经导管主动脉瓣置换术(TAVR)一种罕见但可能危及生命的并发症。传统上,假性动脉瘤通过手术治疗;然而,经导管技术和器械技术的改进使经皮闭合LVP成为一种越来越可行的选择,特别是对于不适合手术的患者。TAVR候选患者手术风险很可能增加或无法进行手术。因此,经皮闭合LVP可能是一种合理的策略,但其在这种新兴的主动脉瓣手术之后的经验仍然有限。我们描述了1例TAVR术后LVP形成的病例,其中通过经心尖途径经LVP进行经皮闭合有效地治疗了该病例。首次尝试采用经股动脉途径。闭合前血管造影显示LVP颈部呈偏心形状,类似“鸡腿”。这种形状导致用导丝穿过LVP非常困难,未能成功。然而,LVP位于心尖,我们在第二次尝试中能够从胸壁通过假性动脉瘤进入。这种方法允许进行紧密且同轴的导丝操作,最终穿过了LVP颈部。此后,部署了闭合装置,第二次手术成功完成。途径选择通常有助于手术成功。这是首例TAVR术后经心尖途径进行经皮LVP闭合的病例,可能提示这种途径作为TAVR候选患者进行这种导管闭合的一种可能选择。© 2016威利期刊公司
