The Ross Operation shows excellent 10-year survival (96.9%) and low reoperation rates for both pulmonary autografts and homografts. This procedure is ideal for aortic valve disease in young patients.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Pediatric Cardiac Surgery

Background:

  • The Ross Operation is a complex surgical procedure for aortic valve disease.
  • Evaluating long-term outcomes is crucial for patient management and procedural refinement.

Purpose of the Study:

  • To assess the 10-year outcomes of the Ross Operation.
  • Analyze survival rates, reoperation incidence, and graft performance (pulmonary autografts and homografts).
  • Evaluate right ventricular outflow tract reconstruction.

Main Methods:

  • A cohort of 227 patients underwent the Ross Operation between 1995 and 2005.
  • Pulmonary autografts were used in most cases (total root replacement).
  • Right ventricular outflow tract reconstruction utilized cryopreserved homografts, homografts with pericardium, or decellularized homografts.

Main Results:

  • Hospital mortality was 3.5%, with 10-year survival at 96.9%.
  • Reoperation-free rates at 10 years were high for both autograft (96.4%) and homograft (96.2%) groups.
  • Decellularized homografts reduced late gradients in left ventricular outflow tract reconstruction.

Conclusions:

  • The Ross Operation demonstrates excellent long-term survival and low morbidity.
  • It is considered a superior option for surgical treatment of aortic valve disease in children and young adults.
  • Low reoperation rates and graft durability support its continued use.
