Secundum atrial septal defect and cleft mitral valve

Area of Science:

• Cardiology
• Cardiac Surgery
• Pathology

Background:

• Atrial septal defects (ASDs) are common congenital heart conditions.
• Mitral insufficiency can be associated with secundum ASDs.
• Understanding the specific mitral valve pathology is crucial for surgical planning.

Observation:

• Five patients with secundum ASD and mitral insufficiency were studied.
• A consistent cleft mitral valve anatomy was observed in all patients.
• Two patients exhibited cleft valves preoperatively, even when only mitral valve prolapse was suspected.

Findings:

• The pathological anatomy revealed a specific type of cleft mitral valve in all cases.
• The cleft mitral valve is a significant finding in patients with secundum ASD and mitral insufficiency.
• Preoperative diagnosis of cleft mitral valve may be challenging.

Implications:

• The presence of a cleft mitral valve has significant surgical implications.
• Accurate preoperative assessment and intraoperative identification of the cleft mitral valve are essential.
• This finding may influence surgical techniques and outcomes for patients with this combined defect.
