REsting FLOW rate to determine true Aortic valve Severity (REFLOW-AS).

BACKGROUND Patients with low gradient severe aortic stenosis (AS) are clinically challenging cohort requiring additional imaging modalities to secure diagnosis of severe AS. We aimed to assess whether resting aortic valve area (AVA) can determine hemodynamic severity of AS in patients with high trans-valvular flow rate...
