Mesenteric ischemia following large left ventricular fibroid thrombosis due to myocardial infarction: A case report

INTRODUCTION: Left ventricular thrombosis is a common complication of acute myocardial infarction, usually occurring after anterior ST-elevation myocardial infarction, akinesis, and extensive dyskinesia of the apex, anterolateral, or anteroseptal. In this article, we report a case of myocardial infarction with left ventricular thrombosis. CASE PRESENTATION: A 45-year-old man was referred to our hospital with complaints of severe epigastric pain, sweating, fever, and tachycardia. In laboratory tests, findings for triose phosphate isomerase enzyme were negative, but on electrocardiography, the Q wave in the V1 and V2 leads and the biphasic T wave in the V2, V3, and V4 leads were evident. In Akinesian echocardiography, apical segmentation with a large organic, mobile, pedunculated thrombosis measuring 1.7 × 1.9 cm(2) and an ejection fraction of 40% were reported. The patient then underwent emergency open cardiac surgery through a central sternotomy to remove the thrombosis. CLINICAL DISCUSSION: The clinical manifestations of left ventricular thrombosis include cerebral thromboembolism and systemic distal embolization, which are dangerous despite surgery. The echocardiography revealed that the left ventricular keratosis had been surgically removed through ventriculotomy. The patient experienced mesenteric ischemia during hospitalization, and due to the initial presentation of severe abdominal pain, it is not uncommon for the patient to be diagnosed with mesenteric ischemia before referral. The patient had the following vital signs: SPO(2), 98%; BP, 96/63; PR, 91; RR, 19; and GCS, 10/15 and was treated in the intensive care unit. CONCLUSION: Our case highlights the importance of diagnosis and on-time treatment of post-large left ventricular fibroid thrombosis complications.
