METHODS: Among 3369 consecutive patients with severe aortic stenosis (AS) in the CURRENT AS Registry-2, we analyzed 2824 patients with natriuretic peptide (NP) and left ventricular ejection fraction (LVEF) data. Patients were classified as SVS (no symptoms with low NP), PVS (mild symptoms and/or mildly elevated NP), or AVS (acute deterioration and/or markedly elevated NP or reduced LVEF), and stratified by initial aortic valve replacement (AVR) and conservative strategies. The primary outcome was a composite of death or heart failure hospitalization. Subgroup analyses further classified patients into five phenotypes: SVS, progressive valve signs without symptoms, progressive valve symptoms, acute valve signs without symptoms, and acute valve symptoms.
RESULTS: In the initial AVR stratum, AVS was associated with higher risk for the primary outcome compared with SVS (adjusted HR 2.34, 95% CI 1.19-4.59, P=0.01), whereas PVS was not. In the conservative stratum, SVS demonstrated a very low early event rate (1.0% at 6 months), while AVS and PVS had higher risk than SVS. In the five-phenotype analysis, patients with progressive valve signs without symptoms underwent AVR at rates comparable to SVS yet had worse outcomes than SVS in the conservative stratum (adjusted HR 1.89, 95% CI 1.18-3.03, P=0.008).
CONCLUSIONS: A valve syndrome framework highlights limitations of symptom-based risk stratification and may refine surveillance and intervention strategies in severe AS.
