Outcome of normal flow low gradient “severe” aortic stenosis with preserved left ventricular ejection fraction: A propensity matched study

ConclusionThis study shows that NF-LG-SAS have a comparable outcome to that of MAS when AVR was performed during follow-up according to guidelines, mostly at the stage of high-gradient AS. Rigorous echocardiographic assessment to rule out measurement errors and close follow-up are essential in NF-LG-SAS to detect progression to true severe AS. Overall survival in propensity matched population (Fig. 1).
