This study presents a novel aortic valve repair technique using autologous pericardium for rheumatic aortic regurgitation. The method demonstrated excellent short- and medium-term results, with 87% of patients showing absent or minimal regurgitation.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Valve Repair
  • Rheumatic Heart Disease

Background:

  • Rheumatic aortic regurgitation involves cusp retraction and impaired coaptation.
  • Effective surgical repair strategies are crucial for managing this condition.

Purpose of the Study:

  • To describe and evaluate a technique for aortic valve repair using autologous pericardium to extend retracted cusps.
  • To report the short- and medium-term outcomes of this novel repair method.

Main Methods:

  • A cohort of 52 patients (mean age 21 years) with rheumatic aortic regurgitation underwent cusp extension repair with autologous pericardium.
  • Postoperative and 2-year follow-up included echocardiographic assessment of aortic regurgitation.

Main Results:

Related Experiment Videos

  • No operative deaths or reoperations for technical failure occurred.
  • Absent or minimal aortic regurgitation was observed in 87% of patients postoperatively.
  • Moderate regurgitation was present in 13% of patients, with stable results at 2 years.

Conclusions:

  • Aortic valve repair by cusp extension with autologous pericardium is a reproducible and reliable technique for selected patients.
  • The procedure shows promising short- and medium-term efficacy in addressing rheumatic aortic regurgitation.
