Left ventricular (LV) rupture after myocardial infarction (MI) occasionally results in formation of LV pseudoaneurysm (LVPA) which is prone to rupture because of its thin wall. However, cases of LVPA without ST changes including segment elevation in electrocardiogram (ECG) are rare. In this case, we describe a patient who had relatively mild symptoms and giant LVPA with no specific ECG changes following MI with a confirmed diagnosis via transthoracic echocardiography. Although surgical treatment options are often recommended, conservative therapy was adopted, following which the patient had been well-medicated using antihypertensive drugs and anticoagulants. <Leaning objectives: Left ventricular pseudoaneurysm (LVPA) is usually accompanied by ST segment changes on electrocardiogram (ECG) due to myocardial damage. However, we should take into account a LVPA without ECG specific changes, so echocardiography is better to be considered for an identification. Although many LVPA patients undergo surgery because of risk for rupture, some cases with stable hemodynamic status can have long-term survival with conservative therapy such as anti-hypertension and coagulation.>
