Key result
AVR improves outcomes over conservative management in true-severe classical and paradoxical LF-LG AS.
Why the study?
The severity of low-flow, low-gradient aortic stenosis continues to be misunderstood due to challenging diagnosis, and its treatment remains complex.
How is low-flow, low-gradient aortic stenosis diagnosed and managed?
How is low-flow, low-gradient aortic stenosis diagnosed and managed?
Accurate diagnosis of low-flow, low-gradient aortic stenosis using advanced imaging is crucial, as aortic valve replacement provides better outcomes than conservative management in true-severe cases.
Accurate diagnosis guides AVR decisions in LFLG AS; extends observational data but leaves open need for RCTs.
PURPOSE OF REVIEW: The severity of low-flow, low-gradient aortic stenosis cases continue to be misunderstood because of challenging diagnosis, and treatment remains complex. We discuss current diagnostic and treatment modalities for low-flow, low-gradient aortic stenosis. RECENT FINDINGS: This article summarizes current guidelines and best practices for the management of low-flow, low-gradient aortic stenosis. SUMMARY: Low-flow, low-gradient aortic stenosis is a difficult entity to diagnose and treat. Various diagnostic modalities are needed to accurately determine the severity of aortic stenosis and potential treatment benefit. True-severe classical and paradoxical low-flow, low-gradient aortic stenosis can be distinguished from pseudo-severe aortic stenosis by dobutamine stress echocardiography and/or multidetector computed tomography. Once the distinction is made, aortic valve replacement results in better outcomes compared with conservative management. Although both surgical and transcatheter aortic valve replacement result in adequate outcomes, the decision between the two treatment strategies is based on patient characteristics, valve morphology, and other risk factors.

Salemi et al. (2019) conducted a review in Low-flow, low-gradient aortic stenosis. Aortic valve replacement vs. Conservative management was evaluated. Aortic valve replacement results in better outcomes compared with conservative management for true-severe classical and paradoxical low-flow, low-gradient aortic stenosis.
