Low-Gradient Aortic Stenosis

Echocardiography is the key tool for the diagnosis and evaluation of aortic stenosis. Because clinical decision-making is based on the echocardiographic assessment of its severity, it is essential that standards be adopted to maintain accuracy and consistency across echocardiographic laboratories. The course will discuss some anatomical considerations that focus in particular on the optimization of left ventricular outflow tract assessment, low flow, low gradient aortic stenosis with preserved ejection fraction, an up-to-date classification of aortic stenosis by gradient, flow and ejection fraction, and a grading algorithm for an integrated and stepwise approach of aortic stenosis assessment in clinical practice. 

Target Audience

Cardiologists, Physician Assistants, Nurses, Nurse Practitioners, Respiratory Therapists (Personal Growth) and Sonographers.

Learning Objectives

  • Define low-gradient aortic stenosis.
  • Differentiate between the different types of low-gradient aortic stenosis.
  • Review hemodynamic terms associated with each subtype of low-gradient aortic stenosis.
  • Review the algorithm for diagnosis and work-up of low-gradient aortic stenosis.
