“…Kandheria et al 13 reported only 1 patient among 21 (4.7%) with mitral bioprosthetic thrombosis, and Daniel et al 14 reported a thrombus in 1 out of 113 (0.8%) patients. On the other hand, Oliver et al 17 , studying 161 (9.3%) patients with mitral bioprosthesis of the porcine type with signs of prosthetic dysfunction assessed on TEE, reported 15 patients with thrombosis, a frequency similar to that of the pathological findings previously reported.…”

“…This technique provides accurate images for the definition of the thickness of the leaflets and their mobility, allowing an a dequate diagnosis of calcifications, stenoses, and ruptures [9][10][11][12] . Nonetheless, the descriptions of bioprosthetic mitral valve thrombosis on TEE are rare [13][14][15][16][17] . In regard to the treatment of metallic prosthetic thrombosis, the thrombolytic agent has been efficient in a significant number of cases [18][19][20][21] , although the use of oral anticoagulants prior to the thrombolytic agent has also been effective on some occasions, when one is not dealing with an acute hemodynamic decompensation 22 .…”

“…9 The aortic valve lies in a plane perpendicular with the oesophagus, with a flow that has an asymmetric profile, therefore assessment of a prosthetic aortic valve by TOE may be more challenging. However, TOE is useful in detecting abnormalities of aortic valve prosthesis, particularly those related to periprosthetic tissue.…”

“…Its image quality is superior to that of transthoracic echocardiography, and so this technique rapidly gained widespread acceptance. It has been particularly useful in evaluations of prosthetic valve dysfunction, detection of infective endocarditis, diagnosis of thoracic aortic dissection, evaluation of ventricular function in patients with poor acoustic windows, and detection of left atrial (LA) or left atrial appendage (LAA) thrombus [4][5][6][7][8][9][10][11][12].…”

Background. Standard multiplane transesophageal echocardiographic probes have large transducer tips that could increase patient discomfort, especially during esophageal intubation. A miniaturized biplane probe has been developed for pediatric use; however, its utility for adult patients is unknown. Methods.The miniaturized biplane imaging was tested in 48 anesthetized, ventilated adult patients during cardiac surgery and was compared with the standard multiplane imaging. We evaluated the image quality of cardiac structures and thoracic aorta using a five-grade scoring system. We also measured the left ventricular end-diastolic dimension (LVEDD, mm) and the peak flow velocity (cm/s) of the left atrial appendage (LAA) by pulsed-wave Doppler.Results. Esophageal intubation with the multiplane probe was unsuccessful in 1 patient, although this patient was successfully intubated with the biplane probe. There were no complications with either probe. The image qualities of the left ventricle, mitral valve, aortic valve, and ascending aorta by the biplane probe were inferior to those by the multiplane one. On the other hand, left atrium (LA), LAA, interatrial septum, aortic arch, and descending aorta were as well visualized by the biplane probe as by the multiplane one. The values of LVEDD and peak flow velocity of LAA were not different between the probes. LAA thrombus in 2 of 47 patients and aortic dissection (Stanford type A) in 7 were also well detected by both methods.Conclusions. The resolution of the two-dimensional images in the near fields of the miniaturized biplane probe was as good as the standard multiplane one. The miniaturized biplane probe was found to be applicable to the detection of LA or LAA thrombus and assessment of LAA function in adults.(J Echocardiogr 2004; 2: 83-89)
