COVID myocardial involvement presenting as left ventricular aneurysm and clot associated with normal coronary anatomy, deep vein thrombosis, and abnormal brachial artery flow-mediated dilatation

A 40-year-old non-diabetic, non-hypertensive male patient presented with complaints of dyspnea of a few days duration and coronavirus -19 disease (COVID) pneumonia. The electrocardiography (ECG) revealed sinus tachycardia with T inversion in V1 only. The ECG revealed a left ventricular aneurysm with a clot and severe left ventricular dysfunction. He had deep vein thrombosis involving the left lower leg. The cardiac magnetic resonance imaging revealed a left ventricular posterodorsal aneurysm with a large clot. Computed tomography angiography revealed normal coronaries and no evidence of pulmonary embolism or aortitis. The d-dimer was raised. A brachial artery Doppler revealed severe impairment of flow-mediated dilatation, suggesting endothelial dysfunction. He was stabilized with anti-platelets and anticoagulants, and diuretics.
