Aortic stenosis, non-rheumatic

Last edited: 4/22/2026

Overview

Aortic stenosis, non-rheumatic, refers to the narrowing of the aortic valve orifice not caused by rheumatic heart disease, leading to impaired left ventricular outflow and potential heart failure symptoms 1.

Diagnosis

  • Echocardiography is essential for diagnosis, assessing valve area, mean gradient, and valve morphology 1.
  • Cardiac catheterization may be used for hemodynamic assessment in complex cases 1.
  • Grading typically follows the American Heart Association/American College of Cardiology guidelines, categorizing severity based on valve area and velocity indices 1.

    • Management

  • Surgical Aortic Valve Replacement (AVR): First-line treatment for severe symptomatic aortic stenosis 1.
  • Transcatheter Aortic Valve Replacement (TAVR): Recommended for high-risk surgical candidates 1.
  • Medical Management: Focuses on symptom relief and management of comorbidities; includes diuretics, vasodilators, and anticoagulation as needed 1.

    • Special Populations

  • Elderly: TAVR is increasingly favored over surgical AVR due to lower perioperative risk 1.
  • Comorbidities: Presence of comorbidities influences the choice between surgical and transcatheter approaches 1.

    • Key Recommendations

  • Surgical AVR or TAVR should be considered for patients with severe symptomatic aortic stenosis (Evidence: Strong 1).
  • Echocardiography is the primary diagnostic tool for assessing aortic stenosis severity (Evidence: Strong 1).
  • TAVR is recommended over surgical AVR in high-risk elderly patients (Evidence: Moderate 1).
