Abstract
Transcatheter aortic valve implantation (TAVI) is now routinely performed to treat
inoperable and high-risk patients with severe aortic stenosis (AS). Transapical or
transaortic approaches are alternative routes used when peripheral accesses are unsuitable.
Correct placement of the device is achieved with the help of an angiography performed
with a pigtail catheter to identify the deployment view. However, in patients with
severe vascular disease, placement of a pigtail catheter may not be possible.
We report a modified single-puncture technique, whereby a single access point is used
to perform both angiography and TAVI by using visible calcification landmarks as reference
points.
