Endoventricular Pericardial Patch Repair of a Giant Left Posterior Ventricular Aneurysm

Abstract

Background/aim: Left ventricular aneurysms are complications following acute myocardial infarction. Left posterior left ventricular aneurysms occurring in a submitral position constitute a minor entity, and those leaving the mitral apparatus intact are extremely rare.

Case report: Herein, we report the case of a 58-year-old patient with a past medical history of coronary artery disease and myocardial infarction with a giant left posterior left ventricular aneurysm with moderate mitral valve incompetence.

Results: The patient underwent myocardial revascularization and, through a transaneurysmal approach, successful endoventricular pericardial patch wall reconstruction with no impact on mitral valve competence.

Conclusion: Whenever the mitral valve is not affected, a trans aneurysmal approach with endoventricular pericardial patch in association with myocardial revascularization represents a safe and reproducible approach with good functional outcomes.
