Illustration of the Additional Value of Real-time 3-dimensional Echocardiography to Conventional Transthoracic and Transesophageal 2-dimensional Echocardiography in Imaging Muscular Ventricular Septal Defects: Does This Have Any Impact on Individual Patie

RT3DE imaging of muscular VSD can accurately display the exact geometry of the defect, which can have significant impact on treatment strategies of individual patients. This new imaging modality should be an important adjunct to the standard transthoracic echocardiographic and TEE imaging of these defect before any intervention.
