Giant left atrial appendage aneurysm in a neonate

Area of Science:

• Cardiology
• Pediatric Surgery
• Medical Imaging

Background:

• Giant aneurysms of the left atrial appendage (LAA) are uncommon cardiac anomalies.
• These are typically diagnosed in adult patients.
• Congenital giant LAA aneurysms in neonates are exceptionally rare.

Purpose of the Study:

• To report a rare case of a giant LAA aneurysm in a neonate.
• To describe the diagnostic process and surgical management.
• To emphasize the role of advanced imaging and surgical considerations.

Main Methods:

• Case report of a neonate with a giant LAA aneurysm.
• Preoperative evaluation using echocardiography and cardiovascular magnetic resonance imaging (CMR).
• Surgical intervention for aneurysm repair.

Main Results:

• Successful diagnosis of a giant LAA aneurysm in a neonate.
• Detailed visualization of the aneurysm and surrounding structures via echocardiography and CMR.
• Surgical repair was performed, addressing the challenges associated with neonatal anatomy.

Conclusions:

• Giant LAA aneurysms can occur congenitally in neonates.
• Echocardiography and CMR are crucial for preoperative assessment.
• Surgical repair presents unique challenges in neonates requiring specialized approaches.
