Multiplane Transesophageal Echocardiographic Evaluation of Defects of the Atrioventricular Septum: The Crux of the Matter

The availability of multiplane transesophageal probes has dramatically facilitated visualization of complex cardiac anatomy, with full dynamic tracking of anatomic contiguity. This report describes the unique applicability of multiplane transesophageal echocardiography (TEE) for visualization and assessment of a spectrum of congenital cardiac defects involving the cardiac crux, including the atrioventricular septum, inlet muscular septum, and the atrioventricular valves. With further evolution and progressive miniaturization of these probes, the use of this echocardiographic modality will hopefully encroach into the young infant age range, permitting enhanced preoperative and perioperative depiction of complex congenital cardiac anatomy.
