Incidence of complications in pediatric transesophageal echocardiography: experience in 1650 cases.
The purpose of this study was to tabulate the complications encountered in 1650 patients who underwent pediatric transesophageal echocardiography. The occurrence of complications and their type and severity were prospectively recorded. The patients had a mean age of 3.6 years (range 1 day to 21 years) and a mean weight of 17.2 kg (range 1.6 to 118 kg). ⋯ No significant bleeding, arrhythmias, esophageal injuries, or deaths occurred. Failure to insert the probe and airway complications occurred predominantly and significantly in smaller subjects. It is concluded that the incidence of complications during pediatric transesophageal echocardiography is low.

Case ReportsAtrial thrombosis in cardiac amyloidosis: diagnostic contribution of transesophageal echocardiography.
Few cases of atrial thrombosis detected by transesophageal echocardiography (TEE) in cardiac amyloidosis have been reported recently. We present the cases of 3 consecutive patients affected by AL-type cardiac amyloidosis, symptomatic for heart failure and in sinus rhythm. ⋯ Our experience confirms the association between cardiac amyloidosis and atrial thrombosis, even in sinus rhythm. TEE should be considered to assess thromboembolic risk in all cases of cardiac amyloidosis with severe diastolic dysfunction.

Case ReportsEchocardiographic diagnosis of left ventricular outflow tract obstruction caused by an acquired subaortic membrane after mitral valve replacement.
Although an acquired subaortic membrane has been reported as a cause of left ventricular outflow tract (LVOT) obstruction in various clinical settings, it previously has not been reported after mitral valve surgery. We describe 3 cases of acquired LVOT obstruction that resulted from development of a subaortic membrane after mitral valve replacement. This report emphasizes the role of an acquired subaortic membrane in LVOT obstruction after mitral valve replacement, the use of echocardiography in diagnosing this condition, and the importance of early intervention.
