Percutaneous transapical pseudoaneurysm closure following transcatheter aortic valve replacement

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.
