Multiplane Esophageal Echocardiography

pp 345-353

Abstract

Background

The main aim of this paper is to analize the experience with this technique, his methodology, indications, advantages and cost-benefit analysis, compared with monoplane trans-esophageal echo.

Method

The first 1000 multiplane studies performed inhospitalized and outpatients were included. Mostpatients had native valve diseases, prostheticvalves or were examined for the search of anembolic source.

Results

The multiplane probe has a better diagnostic capacity mainly because it allows the analysis of structures not easily reached by mono or biplane probes. Such is the case for the left ventricular out-flow tract, aortic root, mitral valve apparatus and some segments of both ventricles. Also in native or prosthetic valves the regurgitant jets are better disclosed. In cardiac tumors and other masses as in the diagnosis and complications of bacterial endocarditis, multiplane probes seems to be more in-formative. The main advantage is the easy obtention of specific sections and a 180 degrees continuous imaging without intraesophageal steering, which means less discomfort to the patient. In spite of the fact that the transducer is larger than common esophageal probes there is no additional difficulties to pass it into the esophagus. Two draw-backs: a) the high cost of the device and b) a larger training time for the operator.

Conclusions

Multiplane probes are a step forward in the low risk transesophageal echocardiography.
