Left Ventricular Diverticulum with Contractile Function in an Unusual Site

The diverticulum of the left ventricular cavity is a rare congenital malformation. Various imaging modalities such as echocardiography, computed tomography, magnetic resonance imaging, and left ventriculography might be used for anatomic and functional properties of this abnormality. This report presents the case of a 48-year-old man with a contractile left ventricular diverticulum in the left ventricular outflow tract area and the evaluation with real-time multiplane and 3-dimensional transthoracic echocardiography.
