Key result
Novel guide extension catheter technique secures coronary access for artery protection during high-risk ViV TAVR.
Why the study?
Intra-operative coronary arterial occlusion remains a significant source of morbidity during TAVR, particularly in valve-in-valve applications or cases with high-risk anatomy.

Transcatheter aortic valve replacement (TAVR) has become increasingly common as the indications expanded to include valve-in-valve (ViV) applications and a wider patient population with lower surgical risk. Intra-operative coronary arterial occlusion remains a significant source of morbidity, particularly in ViV applications or cases with high-risk anatomy. We present a novel technique for coronary artery protection utilizing a guide extension catheter to secure coronary access during valve deployment and a ViV case demonstration in a patient with prior surgical aortic valve replacement.

Alomari et al. (2023) conducted a case report in Prior surgical aortic valve replacement undergoing valve-in-valve TAVR (n=1). Guide extension catheter for coronary artery protection was evaluated. A novel technique utilizing a guide extension catheter was presented to secure coronary access for coronary artery protection during a high-risk valve-in-valve transcatheter aortic valve replacement.
