Aortic angle distribution and predictors of horizontal aorta in patients undergoing transcatheter aortic valve replacement

Horizontal aorta (HA) is an anatomical feature that can pose significant technical challenges for the successful positioning of the bioprosthetic valve during transcatheter aortic valve replacement (TAVR). Physiological range of aortic angle (AA) is unknown; hence there is no cutoff AA for classifying HA. Moreover, patient characteristics predicting HA are under-investigated.
