MI Complication (Ventricular Pseudoaneurysm) (3–14 days Post-MI)

Ventricular pseudoaneurysm is a serious heart condition that can develop after a heart attack, specifically between 3 and 14 days afterward. It involves a tear in the heart muscle wall, but instead of blood leaking freely, it is contained by the outer layers of the heart or scar tissue, forming a false sac. This condition affects the heart's pumping ability and can lead to dangerous complications like rupture or heart failure. The main body system involved is the cardiovascular system, particularly the left ventricle. Symptoms may include chest pain, shortness of breath, or signs of heart failure. Early detection is crucial because this condition can be life-threatening if not treated promptly.

Ventricular pseudoaneurysm is a post-myocardial infarction complication characterized by a contained rupture of the ventricular free wall, typically occurring 3 to 14 days after the infarct. It results from myocardial necrosis and subsequent rupture, where the rupture is sealed by adherent pericardium or scar tissue rather than myocardium, forming a false aneurysm. This differs from a true aneurysm, which involves all layers of the ventricular wall. The condition is significant due to the high risk of rupture, leading to cardiac tamponade and sudden death. It commonly follows a transmural infarction and is associated with persistent chest pain, heart failure, or new murmurs. Diagnosis and management are critical to prevent fatal outcomes.
