Pre-procedural transthoracic echocardiography (TTE) showed mildly depressed left ventricular (LV) systolic function with hypokinesis of the inferior wall and presence of a well-organized thrombus attached to apical segments of LV (28 x 21 mm) (Figure 1 A). The occlusion was crossed with a Balance Middleweight guide wire (Figure 1 B) and the thrombus was aspirated using an Export thrombectomy catheter (Figure 1 C). The aspirated thrombus (Figure 1 D) was then stored in neutral buffered formalin and PolyTransport buffer. Promus Element stent was implanted in the lesion and post-dilated with a 4.0 x 15 mm non-compliant balloon, leading to complete restoration of the patency of the vessel with a small distal residual thrombus (Figure 1 E). Prolonged ECG monitoring showed no proof of atrial fibrillation. The histopathologic examination, which comprised standard hematoxylin and eosin staining, showed a complex structure, characterized by hypocellular retracted fibrin conglomerate, partially infiltrated with neutrophils (Figures 1 F and G).
