“…These data are in accordance with reports on multiplane TEE which showed that structures with a complex spatial orientation such as aortic valve, ascending aorta, aortic arch, and coronary arteries are more easily and completely assessed with multiplane TEE [7,[13][14][15][16][17][18] . Thus, multiplane TEE appears to be an ideal method to give detailed anatomical information about the morphology of a dissection, and can also show the consequences and complications of proximal extension.…”

Aims:The purposes of this study were to compare the accuracy of multiplane vs. biplane transoesophageal echocardiography (TEE) in the diagnosis of aortic dissection and aortic intramural haematoma, and to test whether these techniques provide all the diagnostic information required to make management decisions. Methods and Results:Fifty-eight consecutive patients with clinically suspected aortic dissection were studied with multiplane TEE; all cases who required surgery underwent intraoperative monitoring with multiplane TEE.The following multiplane TEE data were analysed: the angle between current and 0 plane at which each view was obtained; the success rate in the evaluation of true and false lumen, entry tear, coronary artery involvement, aortic regurgitation, pericardial effusion. Advantages of multiplane over biplane TEE have been evaluated by the demonstration of usefulness of views obtained in planes other than 0 -20 or 70 -110 , assuming that with manipulation of a biplane probe a 20 arc could be added to the conventional horizontal and vertical planes.On the basis of TEE findings, aortic dissection was confirmed in 36 cases (18 type A, 12 type B, six intramural haematoma). The specificity and sensitivity of TEE in terms of the presence or absence of aortic dissection or intramural haematoma were 100%. An additional clinical value of multiplane over biplane TEE in the evaluation of ascending aorta, aortic arch, entry tears and coronary artery involvement was demonstrated. All cases with type A aortic dissection or intramural haematoma involving the ascending aorta had an operation that was performed immediately after the diagnosis (hospital mortality, 13%). Patients with type B aortic dissection were treated medically; 25% of these cases were operated later (hospital mortality, 0%). Conclusions:Multiplane and biplane TEE have excellent and similar accuracies in the evaluation of aortic dissection and intramural haematoma. Multiplane TEE improves the visualization of coronary arteries, aortic arch and entry tears; it appears to be an ideal method as the sole diagnostic approach before surgery in type A aortic dissection.

“…More recently, multiplane TEE probes have become available, allowing stepwise study of an area of interest by fine mechanical or electronic rotation of the scanning plane through 180 degrees. [16][17][18][19][20][21][22] …”

“…Die Kontraktion des Myokards, der Füllungszustand der Kammern und die Klappenfunktion werden damit einer kontinuierlichen Beobachtung zugänglich und können mit zusätzlichen Verfahren, etwa der dopplerechokardiographischen Klappenuntersuchung, einer ergänzenden Beurteilung unterzogen werden. in deren Schallkopf die angeordneten Wandler durch einen miniaturisierten Elektromotor bis zu 180 Grad um ihren Mittelpunkt gedreht werden können, was die Einstellung von beliebigvielen Zwischenebenen ermöglicht (29). Der Schallkopf dieser sogenannten ,,omniplanen" Sonde ist im Vergleich zur monoplanen Sonde nur wenig gröger und arbeitet wahlweise mit Frequenzen von 3,75 oder 5 MHz.…”

Transoesophageal echocardiography (TEE) is a visualising ultrasound technique that has entered the arena of anaesthesiology and intensive care shortly after its clinical introduction in the early 80s. Due to transducer positioning close to the heart, two-dimensional echocardiograms render high spatial resolution of cardiac structures and in adequate views continuously demonstrate the complete course of cardiac filling and contraction. The high sensitivity of the method, numerous options to assess morphological and functional parameters, and the low related risk involved for the patient explain the growing interest in TEE as a perioperative monitoring device. This utilisation, however, is currently limited by the high costs of the ultrasound equipment, the demand for specialists knowledge, the cost-benefit relation not yet thoroughly explored and the little propagated knowledge of the method's capacity. In addition, the need for information is growing due to the permanent technological progress of the equipment, which recurrently requires actualization in evaluating TEE.
