Volume-flow (V-Q) discordance occurs in nearly one-third of patients with severe aortic stenosis post-TAVR and offers superior prognostic value over existing SVi and TFR thresholds (P=0.047).
Observational
p-value: p=0.047
BACKGROUND: Current flow (Q) assessment in aortic stenosis (AS) uses stroke volume index (SVi), a volume (V)-based measure. However, V differs fundamentally from Q, which is defined as volume per unit time (mL/s). OBJECTIVES: ) undergoing transcatheter aortic valve replacement (TAVR). METHODS: with TFR <210 mL/s. RESULTS: (AIC: 29.59; P = 0.047) or TFR <210 mL/s (AIC: 32.80; P = 0.049). CONCLUSIONS: V-Q discordance occurs in nearly one-third of patients with AS post-TAVR and offers superior prognostic value over existing SVi and TFR thresholds.
Hungerford et al. (Wed,) conducted a observational in Severe Aortic Stenosis. Volume-flow (V-Q) discordance assessment vs. Existing SVi and TFR thresholds was evaluated on Survival (p=0.047). Volume-flow (V-Q) discordance occurs in nearly one-third of patients with severe aortic stenosis post-TAVR and offers superior prognostic value over existing SVi and TFR thresholds (P=0.047).
