Periodic Protrusion of Right Coronary Cusp into Left Ventricular Outflow Tract Due to Detachment from the Aortic Annulus Complicated with Infective Endocarditis.
We describe the imaging of unusual dislocation of right coronary cusp into left ventricular outflow tract (LVOT) due to the infective endocarditis. Although the two-dimensional echocardiography identified a protruding mass in LVOT, the three-dimensional echocardiography precisely demonstrated the spatial anatomy of the aortic root, which was confirmed by the surgical operation, implicating the usefulness of three-dimensional echocardiography in this rare anomaly.
