Insights

The Ross operation shows excellent long-term survival and low rates of autograft regurgitation in pediatric patients with aortic valve disease. This procedure confirms its status as the preferred surgical choice for young individuals requiring aortic valve repair.

Area of Science:

  • Cardiovascular Surgery
  • Pediatric Cardiology
  • Aortic Valve Disease Management

Background:

  • The Ross operation utilizes a pulmonary autograft for aortic valve replacement, offering hemodynamic advantages and growth potential in pediatric patients.
  • Irreparable aortic valve disease in children necessitates surgical solutions with favorable long-term outcomes.

Purpose of the Study:

  • To evaluate the long-term clinical and echocardiographic results of the Ross operation in pediatric patients.
  • To assess the durability and safety of the pulmonary autograft and homograft in the Ross procedure.

Main Methods:

  • A cohort of 55 pediatric patients (mean age 10.0 years) underwent either the Ross operation (n=46) or Ross-Konno procedure (n=9) between 1993 and 2006.
  • Procedures involved aortic root replacement with a mean cross-clamp time of 132 minutes, followed by a mean follow-up of 5.5 years.
  • Echocardiographic assessment included autograft diameter indexed to body surface area and homograft gradients.

Main Results:

  • Actuarial patient survival was 93% at 10 years, with only one early and two late deaths.
  • No patients developed moderate or severe autograft regurgitation; however, autograft dilatation was common but not correlated with regurgitation.
  • Freedom from reoperation for homograft degeneration was 91% at 10 years, with 9% experiencing a mean homograft gradient >= 40 mmHg.

Conclusions:

  • The Ross operation demonstrates a low incidence of autograft regurgitation and a low risk of homograft degeneration in pediatric patients.
  • Autograft dilatation is a frequent finding but does not compromise autograft function.
  • The study reaffirms the Ross operation as the preferred surgical approach for irreparable aortic valve disease in pediatric and young adult populations.
