Postinfarction ventricular aneurysm is defined as a dilatation of the left or right ventricle in a saccular form that can cause its rupture at the level of the ventricular wall or septum and can predispose to endocarditis due to the production of turbulence caused by short circuits that cause damage to the endocardial tissue. with the consequent bacterial colonization and systemic embolism. Once the diagnosis is confirmed, antibiotic treatment should be given and in case of complications, surgical treatment should be considered. We report the case of a male patient with a previous history of acute myocardial infarction, who attended the emergency room due to systemic inflammatory response data, showing endocarditis in the tricuspid valve and a ruptured ventricular aneurysm, causing embolic phenomena in the dorsal column, therefore which required surgical treatment.
