Abstract
Background Because of the high prevalence of renal insufficiency in patients eligible for transcatheter aortic valve replacement (TAVR), a non-contrast evaluation of the aortic root complex along with the entire vascular access route is desirable for pre-procedural evaluation. In this pilot study we proposed to test two novel investigational, non-contrast MRA techniques to develop a protocol for TAVR planning.
Highlights
Because of the high prevalence of renal insufficiency in patients eligible for transcatheter aortic valve replacement (TAVR), a non-contrast evaluation of the aortic root complex along with the entire vascular access route is desirable for pre-procedural evaluation
Aortic root parameters were compared to measurements obtained by conventional cine acquisition, and abdominal aorta and femoral measurements were correlated between the 3D and quiescent-interval single-shot (QISS) MRA acquisitions
No significant difference was found in the diameter of the abdominal aorta or the iliac and femoral arteries between the 3D and the QISS acquisitions (Table 1)
