Abstract

Background: Transcatheter aortic valve replacement (TAVR)is a well-established treatment option for severe aortic stenosis (AS). AS and coronary artery disease frequently coincide, and therefore some patients may require coronary angiography (CAG)and/or intervention (PCI)post-TAVR. Due to valve stent design, most self-expanding prostheses always cover the coronary ostium, and therefore may hinder future access. The objective of this research was to evaluate the incidence, safety and feasibility of CAG/PCI in patients with prior self-expanding TAVR valves. Methods: Among 2170 patients (age 82 ± 6 years, 43% male)who underwent TAVR with Corevalve or Evolut prostheses, as part of the Italian CoreValve ClinicalService® framework (data from 13 Italian centers), the occurrence of CAG/PCI following TAVR and periprocedural characteristics were examined. Results: During median follow-up of 379 days, 41 patients (1.9%)required CAG and/or PCI (total 46; 16 CAG, 14 PCI, 16 both PCI/CAG). 56.5% of the procedures were performed under emergency/urgency settings. Left system coronary angiography was successfully performed in most cases (28/32, 87.5%), while right coronary angiography was successful only in 50.0% (16/32). PCI procedures (20 for left system, 3 for right system, 4 for graft)were successfully performed in 93.3% (28/30)of the procedures. No CAG/PCI procedure-related complications including prosthesis dislodgment or coronary ostium dissection occurred. Conclusions: CAG and PCI procedures following CoreValve TAVR is safe and mostly feasible, although the success rate of selective right coronary angiography was relatively low when compared to the left system. Further investigations are required to explore this issue.
