Abstract: | The recently developed multiplane transesophageal echocardiography (TEE) probes cannot provide real-time synchronous biplane imaging. We have developed a new "Variomatrix" probe that combines the advantages of the rotating mechanism of the multiplane probe with the capability of providing simultaneous, side-by-side imaging. Its advantages are: (1) easy manipulation to obtain the optimal planes; (2) avoidance of excessive movement of the probe inside the esophagus; (3) assessment of oblique planes that are not viewed with the usual biplane probe; (4) better understanding of the continuity of structures by the simultaneous, side-by-side biplane, rotating images, providing clearer three-dimensional conception; and (5) shorter examination time by providing a 180 degrees imaging range by rotating the transducer just 90 degrees . |
