Chronic left ventricular apical thrombosis complicating isolated left ventricular noncompaction in a patient with human immunodeficiency virus infection

See PDF.] a Apical four-chamber view on transthoracic echocardiography (A4C) reveals a thrombus (35 × 24 mm) in the left ventricular apex (LVA) (orange arrowhead). b Color Doppler echocardiographic parasternal short-axis view (PSAX) at the LVA level shows abnormal trabeculae (yellow arrowhead) and a thrombus (orange arrowhead), which fulfill the diagnostic criteria of isolated left ventricular noncompaction (ILVNC). c, d Six and 8 months later, A4C demonstrates the reduced size of the thrombus (8 × 6 mm and 5 × 4 mm, respectively) (orange arrowhead). e A year later, A4C demonstrates the chronic organized thrombus (orange arrowhead). f Speckle-tracking echocardiography is performed to distinguish ILVNC and mere noncompaction-like prominent trabeculae observed in dilated cardiomyopathy after recovery of LVEF. LV mid-wall enhancement by LGE-CMR in patients with HIV has been reported [5]. [...]a chronically organized thrombus was formed (Fig. 1e).
