Acceptance and versatility of the Ross procedure

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Pediatric Cardiology

Background:

• The Ross procedure utilizes a pulmonary autograft for aortic valve replacement.
• Long-term data collection over 31 years provides insights into autograft performance.

Purpose of the Study:

• To assess the long-term efficacy and safety of the pulmonary autograft in the Ross procedure.
• To evaluate the suitability of the Ross procedure across diverse patient demographics and conditions.

Main Methods:

• Analysis of 31 years of collected data on patients undergoing the Ross procedure.
• Review of outcomes related to autograft growth, thromboembolism, endocarditis, and valve function under stress.
• Evaluation of the impact of surgical technique modifications (e.g., root replacement, annular narrowing) on early regurgitation.

Main Results:

• The pulmonary autograft demonstrates excellent long-term performance, supporting its use in young patients, women of childbearing age, and those with congenital aortic stenosis or complex outflow tract obstruction.
• Low rates of thromboembolism observed without anticoagulation.
• Significant autograft growth in children.
• Good outcomes in endocarditis treatment.
• Autograft function comparable to a normal aortic valve under high stress.
• Improved outcomes regarding early regurgitation with modified implantation techniques.

Conclusions:

• The Ross procedure with a pulmonary autograft is highly effective and reproducible.
• It is a suitable option for a wide range of patients, including children and those with specific cardiac conditions.
• While a potential for immune response exists, overall results are excellent.
