A new surgical technique for aneurysmal right atrium.

Area of Science:

• Cardiovascular Surgery
• Cardiac Surgery Techniques
• Congenital Heart Disease

Background:

• Aneurysmal right atrium (ARA) presents significant surgical challenges.
• Giant and friable ARA require specialized reduction techniques.
• Existing methods may have limitations in managing extreme ARA cases.

Observation:

• A new surgical approach for aneurysmal right atrium (ARA) reduction is detailed.
• The technique utilizes extrapleural single-stage caval return.
• Profound hypothermia with circulatory arrest is a key component.

Findings:

• The described method successfully reduced giant, friable ARA cavity dimensions.
• Surgical steps include excising the thinned free atrial wall.
• Double-layer closure of remaining edges to the crista terminalis was performed.

Implications:

• This technique offers a viable option for managing complex ARA.
• It may improve outcomes for patients with giant and friable ARAs.
• Further studies can validate the long-term efficacy and safety of this surgical approach.
