Incidence and feasibility of coronary access after transcatheter aortic valve replacement
Key result
Among 912 patients treated with TAVR, the incidence of coronary access at a median follow-up of 769 days was 5.3%, and percutaneous coronary intervention was successful in all but one case.
Why the study?
The long-term incidence of coronary access after TAVR was unknown, and coronary access and PCI after TAVR may present technical challenges, especially with supra-annular devices.

Implication
Reassures on post-TAVR coronary access feasibility in real-world cohorts; leaves open device-specific optimization for prospective study.

Structured PICO
What is the incidence and feasibility of coronary access after transcatheter aortic valve replacement?
P
Population
912 high-risk patients with aortic stenosis treated with TAVR, followed for a median of 769 days to assess the incidence and feasibility of subsequent coronary access.
E
Exposure
Coronary access (CA) and percutaneous coronary intervention (PCI) after TAVR.
O
Outcome
Incidence, feasibility, and outcomes of coronary access after TAVR.
Coronary access after TAVR is infrequent (5.3%) but generally feasible and safe, though supra-annular devices may present challenges for right coronary artery engagement.

Fovino et al. (2020) conducted a cohort in Aortic stenosis (n=912). Transcatheter aortic valve replacement (TAVR) was evaluated on Incidence of coronary access after TAVR. Among 912 patients treated with TAVR, the incidence of coronary access at a median follow-up of 769 days was 5.3%, and percutaneous coronary intervention was successful in all but one case.
