Multimodality imaging for comprehensive non-invasive diagnosis of aorto-left ventricular tunnel in infancy

BackgroundAorto-left ventricular tunnel (ALVT) is a paravalvular communication between aorta and left ventricle. It is one of the rare congenital heart diseases which could present with heart failure.Case presentationA case of ALVT was diagnosed in infancy. Preliminary assessment was possible using conventional echocardiography; however, functional assessment and accurate anatomy of ALVT were further verified via variable imaging modalities starting from speckle tracking and three-dimensional echocardiography to cardiac CT angiogram. The tunnel was successfully repaired with uneventful recovery.ConclusionsMultimodality imaging can accurately assess cardiac function and demonstrate the anatomy of ALVT noninvasively to plan for successful intervention.
