Area of Science:

  • Cardiovascular Surgery
  • Cardiac Valve Repair
  • Medical Devices

Background:

  • Tricuspid and mitral valve regurgitation are common conditions requiring surgical correction.
  • Existing annuloplasty techniques have limitations in precision and adjustability.
  • Functional atrioventricular regurgitation necessitates effective and durable repair methods.

Purpose of the Study:

  • To evaluate the efficacy and safety of a modified partial annular plication technique.
  • To assess the durability of the repair in patients with moderate to severe tricuspid or mitral regurgitation.
  • To determine the applicability of this adjustable annuloplasty in diverse patient populations.

Main Methods:

  • A modified partial annular plication was performed on 23 patients with moderate to severe tricuspid or mitral regurgitation.

  • An adjustable suture technique using a plastic tube for precise tightening during saline flushing was employed.
  • Intraoperative valve competency was assessed using saline flushing tests.

    • Main Results:

    • Postoperative follow-up (mean 13.8 months) showed 43.5% of patients with no regurgitation and 52.2% with grade 1+ regurgitation.
    • One patient (4.3%) had grade 2+ regurgitation, with no worsening observed post-initial assessment.
    • The adjustable technique allowed for precise plication adjustments, ensuring optimal valve function.

    Conclusions:

    • The adjustable partial annular plication is a simple, exact, and durable surgical option.
    • This technique is effective for treating moderate to severe functional atrioventricular regurgitation in patients of all ages.
    • The procedure offers a reliable method for improving valve competency and patient outcomes.
