The Living Ross Procedure: A New Paradigm in Partial Heart Transplantation

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Transplantation Immunology

Background:

• The Ross procedure, a surgical technique for aortic valve replacement, utilizes a patient's own pulmonary valve (autograft) in the aortic position.
• The right ventricle-to-pulmonary artery (RV-PA) conduit in the Ross procedure, often a homograft, faces limitations in longevity due to stenosis and regurgitation.
• Partial heart transplantation (PHT) offers a potential solution by providing a conduit that can grow with the child.

Observation:

• A novel surgical approach, termed the
• living Ross
• procedure, was applied in a 3-year-old patient with a congenital unicuspid aortic valve.
• This technique involved using a pulmonary autograft for the aortic position and an aortic root allograft from an adult heart transplant recipient as the RV-PA conduit.

Findings:

• The study reports the successful application of PHT for the RV-PA conduit during a Ross procedure.
• The use of an allograft as an RV-PA conduit in this context is a novel adaptation.
• The primary hypothesis is that this modification will enhance the longevity of the RV-PA conduit.

Implications:

• This
• living Ross
• procedure may offer a more durable solution for pediatric patients requiring RV-PA conduit replacement.
• It presents a potential strategy to overcome the long-term complications associated with conventional homografts in the Ross procedure.
• Further research and long-term follow-up are warranted to validate the efficacy and safety of this innovative approach in pediatric cardiac surgery.
