Summary
The Ross operation shows excellent survival and freedom from aortic valve replacement in children. However, homograft valve durability remains a concern, necessitating further research for improved long-term function.
Area of Science:
- Pediatric Cardiac Surgery
- Aortic Valve Replacement
- Autograft Valve Durability
Background:
- The Ross operation is a common aortic valve replacement technique in pediatric patients.
- Long-term outcomes of the pulmonary autograft valve are not well-established.
Purpose of the Study:
- To evaluate the mid-term and late results of the Ross operation.
- Assess autograft valve durability, patient survival, and valve-related morbidity.
Main Methods:
- Retrospective review of 178 pediatric patients (3 days to 17 years) who underwent the Ross operation.
- Analysis of medical records and echocardiographic data for valve function and patient outcomes.
Main Results:
- Actuarial survival was 92±3% at 12 years, with 4.5% operative mortality.
- Freedom from autograft valve degeneration was 90±4% at 12 years; degeneration was worse in aortic insufficiency cases.
- Freedom from autograft replacement was 93±3% at 12 years; homograft valve replacement was needed in 7 patients.
Conclusions:
- The Ross operation offers excellent survival and freedom from aortic valve replacement in children.
- Homograft valve function presents a concern for late outcomes.
- Further research is recommended to enhance homograft valve durability.
