Minimally invasive atrial septal defect closure using the subxyphoid approach

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Cardiac Surgery

Background:

• Atrial septal defects (ASDs) in adults can lead to serious complications like paradoxical emboli and heart failure.
• Traditional surgical closure via sternotomy, while effective, results in significant scarring, particularly concerning for young women.
• Alternative cosmetic incisions carry risks of breast maldevelopment and sensory loss.

Observation:

• The right atrium and atrial septum are anatomically located close to the xyphisternal junction.
• This proximity suggests a potential for accessing ASDs through a less invasive, subxyphoid approach.

Findings:

• A new surgical technique utilizes a small, transverse inframammary incision and lower sternal retraction.
• This subxyphoid approach provides excellent visualization of ASDs, including ostium secundum and patent foramen ovale defects.
• The procedure was successfully performed on two young women with minimal complications.

Implications:

• This minimally invasive subxyphoid technique offers an effective and cosmetically advantageous alternative to sternotomy for ASD closure.
• It eliminates the need for thoracotomy and sternotomy, reducing operative morbidity and improving aesthetic outcomes.
• The approach holds promise for improving patient satisfaction and quality of life after ASD repair.
