Figure 1
CW Doppler analysis of mid-LV obstruction showed an interruption in blood flow from the LV apex to the base during mid-systole (void pattern), followed by a late systole to early diastole paradoxical jet flowing out of the aneurysm.
Figure 2
Contrast echocardiography was used to accurately assess the endocardial border and characterize the apical aneurysm, revealing moderate systolic dysfunction.
Figure 3
Cardiac MRI confirms medio-ventricular HCM in the burn-out stage with severe systolic dysfunction, 16% LGE of LV myocardial mass predominantly at the level of the apical aneurysm, and subendocardial fibrosis in the inferior and inferolateral walls, suggesting myocardial viability.
Figure 4
Echocardiography and speckle tracking imaging showed improved regional kinetics after revascularization, but persistent severe global longitudinal dysfunction, especially at the medio-ventricular and apical levels.
Figure 5
The follow-up echocardiogram highlighted a remodelled LV with an hourglass shape, moderate systolic dysfunction assessed by 3D volumetry with an EF of 36%.
