Aortic root enlargement (ARE) using the Nicks procedure is a safe and effective treatment for elderly patients with severe aortic stenosis and small aortic annulus, showing significant improvements in heart function and reduced ventricular mass.

Area of Science:

  • Cardiovascular Surgery
  • Geriatric Cardiology
  • Cardiac Valve Disease

Context:

  • Severe aortic stenosis poses significant risks, especially in elderly patients.
  • The small aortic annulus in elderly patients presents surgical challenges.
  • The Nicks procedure offers a potential solution for aortic root enlargement (ARE).

Purpose:

  • To evaluate the safety and efficacy of the Nicks procedure for aortic root enlargement (ARE) in elderly patients with severe aortic stenosis.
  • To assess the impact of ARE on cardiac function, ventricular mass, and clinical outcomes.
  • To compare ARE alone versus combined procedures in this patient population.

Summary:

  • Twelve elderly patients (mean age 79.3) with severe aortic stenosis underwent ARE using the Nicks procedure.

  • No deaths occurred; significant improvements were observed in cardiothoracic ratio, NYHA functional class, peak pressure gradient, and left ventricular mass index (LVMI).
  • ARE alone showed a favorable safety profile compared to combined procedures, with comparable echocardiographic results.

    • Impact:

    • The Nicks procedure is a safe and effective option for elderly patients with severe aortic stenosis and small aortic annulus when performed without concomitant procedures.
    • Demonstrates significant regression of left ventricular mass and improvement in cardiac function post-operatively.
    • Highlights the importance of considering ARE as a standalone procedure to minimize risks in this vulnerable population.
