Why the study?
Low coronary heights confer a high risk for coronary obstruction during or after TAVR for severe, symptomatic aortic stenosis.
Highlights the risk of coronary obstruction during TAVR in patients with low coronary heights and the need for preventative strategies.
Urges pre-TAVR coronary height assessment to mitigate obstruction risk; leaves open optimal preventive strategies in high-risk anatomy.
Transcatheter aortic valve replacement (TAVR) is an established treatment for severe, symptomatic aortic stenosis (AS). However, the presence of low coronary heights confers a high risk for coronary obstruction during or after TAVR.
