Aortic valve replacement in small aortic annuli can be challenging. Aortic root enlargement (ARE) can reduce patient-prosthesis mismatch (PPM) without significantly increasing surgery time.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Valve Intervention
  • Aortic Valve Disease

Context:

  • Small aortic annulus presents surgical challenges in aortic valve replacement.
  • Advancements in prosthesis design aim to mitigate issues related to small annuli.
  • Patient-prosthesis mismatch (PPM) is a concern in these cases.

Purpose:

  • To propose an optimal surgical strategy for aortic valve replacement in patients with a small aortic annulus.
  • To evaluate the effectiveness of aortic root enlargement (ARE) in preventing PPM.
  • To analyze the impact of ARE on surgical and ischemic times.

Summary:

  • A retrospective analysis of 158 patients undergoing aortic valve replacement identified 38 (24%) with small aortic annuli.
  • Fourteen of these patients underwent aortic root enlargement (ARE).

  • ARE was associated with a lower incidence of patient-prosthesis mismatch (PPM) and did not significantly prolong operative or ischemic times.

    • Impact:

    • Aortic root enlargement (ARE) is a viable option to avoid patient-prosthesis mismatch (PPM) in small aortic annulus cases.
    • Surgical decision-making requires careful consideration of prosthesis size and potential need for ARE.
    • Development of a chart correlating prosthesis size with actual fit is needed for optimal strategy selection.
