Internal patch repair of an acute left ventricular pseudoaneurysm

Area of Science:

• Cardiovascular Surgery
• Cardiac Surgery
• Interventional Cardiology

Background:

• Left ventricular pseudoaneurysms are uncommon yet severe mechanical complications following acute myocardial infarction.
• Current surgical approaches lack robust data comparing specific techniques.
• Prompt diagnosis and effective intervention are crucial for patient outcomes.

Purpose of the Study:

• To demonstrate a specific surgical technique for repairing a large left ventricular pseudoaneurysm.
• To provide a visual guide for surgeons managing this rare cardiac complication.

Main Methods:

• Video tutorial showcasing a transatrial endoventricular patch repair.
• Mitral valve replacement performed concurrently with pseudoaneurysm repair.
• Utilized cardiopulmonary bypass during the procedure.

Main Results:

• Successful surgical repair of a large left ventricular pseudoaneurysm.
• Patient weaned from cardiopulmonary bypass without mechanical circulatory support.
• Uneventful recovery and discharge from the hospital.

Conclusions:

• Transatrial endoventricular patch repair is a viable surgical option for large left ventricular pseudoaneurysms.
• This technique can be performed safely with good patient outcomes.
• Further research is needed to compare different surgical strategies for pseudoaneurysm repair.
