Key result
Transcaval access for transcatheter aortic valve replacement using a Brockenbrough needle was successfully performed in an 83-year-old man without access complications.
Why the study?
Obtaining access for percutaneous aortic valve implantation is challenging, and alternative techniques for transcaval access are needed for patients at high surgical access risk.

No
The use of a Brockenbrough needle provides a feasible technical alternative for transcaval access in TAVR patients when standard access is impossible.
May offer alternative transcaval access in select TAVR cases; leaves open need for larger validation studies.
The impossibility of obtaining an access to the implant of the percutaneous aortic valve is a great challenge. The transcaval access is an alternative option that is used less frequently in patients with a high risk of surgical access. The usual transcaval access is described with the use of a rigid tip wire, aided by microcatheter and electrosurgery to across from cava vein to abdominal aorta. This clinical case shows a technical alternative to the transcaval access, with the help of Brockenbrough needle, commonly used to perform the transseptal puncture.

Dauvergne et al. (2020) conducted a case report in Severe aortic stenosis (n=1). Transcaval access for TAVR using Brockenbrough needle was evaluated on Successful TAVR implantation and closure of transcaval access. Transcaval access for transcatheter aortic valve replacement using a Brockenbrough needle was successfully performed in an 83-year-old man without access complications.
