Simple Stereoscopic Display of 3-Dimensional Living Heart Anatomy Relevant to Electrophysiological Practice.

Comprehensive appreciation of the 3-dimensional anatomy of the living heart is essential for accurate diagnosis and establishment of safe interventional treatment by clinical electrophysiologists. Three-dimensional images displayed on a 2-dimensional surface usually undergo distortion and are not considered a real 3-dimensional representation because they cannot provide accurate depth perception. Currently, the availability of 3-dimensional visualization techniques, including 3-dimensional printing, 3-dimensional projectors, 3-dimensional monitors, and virtual reality, is limited owing to their limited user-friendliness and high costs. The authors discuss an alternative conventional approach of a cross-eyed method for viewing stereoscopically displayed images for better appreciation of real 3-dimensional images based on a simple technique.
