Summary
The Ross procedure shows good midterm outcomes, with appropriate pulmonary autograft growth in pediatric patients. Long-term follow-up is crucial due to potential autograft insufficiency.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Thoracic Surgery
Background:
- The Ross procedure utilizes the pulmonary autograft for aortic valve replacement.
- Expanded indications for the Ross procedure are driven by optimal hemodynamic performance and autograft growth potential.
- This study reviews institutional experience to evaluate midterm results of the Ross operation.
Purpose of the Study:
- To assess the midterm outcomes of the Ross procedure.
- To evaluate the growth of the pulmonary autograft in pediatric patients.
- To identify potential complications and the need for reoperation.
Main Methods:
- A review of 111 patients who underwent the Ross procedure between 1992 and 1999.
- Patients included those with isolated aortic valve disease and pediatric patients with complex left ventricular outflow tract obstruction.
- Median follow-up was 3.6 years.
Main Results:
- Early and late mortality rates were 2.7% and 3%, respectively, with 5-year actuarial survival at 94%.
- Pulmonary autograft annulus in pediatric patients demonstrated appropriate growth correlating with body surface area.
- Eight reoperations were required for autograft insufficiency, and three for pulmonary homograft obstruction.
Conclusions:
- The Ross procedure demonstrates favorable midterm results.
- Appropriate autograft growth is observed in pediatric patients.
- Close long-term follow-up is recommended to monitor for autograft insufficiency.
