Clinical Impact of Pre-Procedural Percutaneous Coronary Intervention in Low- and Intermediate-Risk Transcatheter Aortic Valve Replacement Recipients

The clinical relevance of as well as the optimal treatment strategy for coronary artery disease (CAD) in patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS) are unclear. Current data are conflicting, and mainly derived from high-risk patients. We aimed to investigate the feasibility and safety of complete revascularization prior to TAVR for severe AS in low- and intermediate-risk patients. We enrolled 449 patients at low (STS score 3 months) complete revascularization on clinical outcome. Primary study endpoint was all-cause mortality. Overall, 58% of patients had no or non-significant CAD; 18% had a history of complete revascularization prior to TAVR and 24% had complete revascularization shortly before TAVR. Two-year all-cause mortality was not different between patients with recent revascularization prior to TAVR and patients with no or non-significant CAD (13.7% vs. 14.2%, p = 0.905). Cox regression did not reveal an effect on all-cause mortality for recent revascularization. The present analysis reassures that percutaneous complete revascularization prior to TAVR procedures is neutral in terms of all-cause mortality in patients at low and intermediate surgical risk.
