Transcatheter Aortic Valve Replacement with Minimal Contrast Dye in Patients with Renal Insufficiency.

ABSTRACT:

Purpose

Concerns have been consistently raised in regards to the considerable amount of contrast dye used during transcatheter aortic valve replacement (TAVR) in patients with renal insufficiency. In the present study, we introduced minimal contrast TAVR and compared its 30-day clinical outcomes with conventional TAVR.

Materials and methods

We retrospectively investigated 369 patients who underwent TAVR between July 2011 and April 2020 in our institute. Among them, 93 patients with severe aortic stenosis and renal insufficiency (estimated glomerular filtration rate ≤50 mL/min/1.73 m²) were included and divided into a conventional TAVR group (n=56) and a minimal contrast TAVR group (n=37). In the minimal contrast TAVR group, the total amount of contrast was <10 mL during the
