Transesophageal echocardiography and right atrial infarction.

Transesophageal echocardiographic findings in right atrial infarction are described. In three patients with myocardial infarction of one or both ventricles, the association of right atrial myocardial infarction was suspected because of anatomic (two-dimensional) and hemodynamic (Doppler) alterations obtained from transesophageal images. Transesophageal interrogation may prove widely applicable in the evaluation of patients with suspected right atrial infarction.
