Mid-term results of the Ross procedure
Summary
The Ross procedure shows excellent medium-term results for aortic valve disease and complex left ventricular outflow tract obstructions. This surgical technique offers high survival and reoperation-free rates in patients requiring aortic valve repair or replacement.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Cardiac Surgery
Background:
- The Ross procedure, or pulmonary autograft, is a complex aortic valve replacement technique.
- Indications for the Ross procedure include congenital aortic valve disease, left ventricular outflow tract obstruction, and prior prosthesis failure.
Purpose of the Study:
- To evaluate the medium-term outcomes of the Ross procedure.
- To assess the efficacy of the Ross procedure in complex cases, including left ventricular outflow tract obstruction.
Main Methods:
- Fifty patients underwent the Ross procedure between 1991 and 1996, with pulmonary homografts used in 45 cases.
- Aorticoventriculoplasty was combined in 16 patients with left ventricular outflow tract obstruction or small aortic valve prostheses.
- Reoperations constituted half of the interventions, with root replacement as the standard approach.
Main Results:
- The mean follow-up was 34.2 months, with 94% completeness.
- Four-year survival was 95% +/- 4%, and reoperation-free incidence was 93% +/- 6%.
- Most autografts showed minimal or no regurgitation, with low systolic gradients.
Conclusions:
- The Ross procedure demonstrates excellent medium-term results.
- The procedure is effective even in patients with complex left ventricular outflow tract obstructions.
