After performing echocardiography, the patient’s echocardiography demonstrated a left ventricular pseudo-aneurysm which had collected a massive amount of thrombus. Three years earlier, the patient had a left atrial myxoma excision with mechanical mitral valve replacement following a presentation with shortness of breath.Clinical discussion: Left ventricular pseudo-aneurysm is a hazardous complication of mostly myocardial infraction and certain cardiac procedures, such as mitral valve replacement, where it may lead to thrombus formation. Due to this condition’s serious risk of lethal rupture and embolization from thrombus formation, as in our case, immediate surgical intervention is essential for its treatment.Conclusion: Left ventricular pseudo-aneurysm is an abnormal finding post-cardiac surgery, and it should be considered during patient evaluation after the surgery immediately and later in life.Keywords: myxoma, pseudo-aneurysm, mitral valve, mechanical valve
