The Ross operation using pulmonary autografts shows excellent mid-term results for aortic valve replacement in young patients, with high survival and improved left ventricular function. This procedure offers a viable alternative for aortic valve repair.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Cardiac Valve Surgery

Background:

  • The Ross operation is an accepted alternative for aortic valve replacement in young adults and children.
  • This study reviews mid-term outcomes of the Ross operation.

Purpose of the Study:

  • To assess the mid-term results of the Ross operation for aortic valve or root replacement using pulmonary autografts.
  • To evaluate the efficacy and safety of this procedure in a pediatric and adult cohort.

Main Methods:

  • Eighty patients underwent aortic valve or root replacement with pulmonary autografts between 1991 and 1997.
  • Preoperative and serial transthoracic echocardiography assessed aortic/pulmonary annuli, gradients, incompetence, and left ventricular function.
  • Intraoperative transesophageal echocardiography was routinely used; various surgical techniques were employed.

Main Results:

  • Early mortality was 1.2%, with no late deaths; 5-year actuarial survival was 98%.
  • All survivors were in New York Heart Association functional class I, free of complications and medications.
  • Seventy-three patients had no significant aortic gradient or incompetence; one developed late aortic incompetence.

Conclusions:

  • The pulmonary autograft provides excellent mid-term results with low mortality and morbidity.
  • The procedure effectively relieves abnormal left ventricular loading conditions.
  • Complete recovery of left ventricular function is observed in most patients post-Ross operation.
