Case ReportsElectrical dissociation within the left atrium and left atrial appendage diagnosed with transesophageal echocardiography.
The authors describe the case of a 79-year-old man with prior mitral valve repair and a maze procedure who developed recurrent atrial fibrillation, in whom transesophageal echocardiography revealed an accessory lobe of the left atrial appendage in sinus rhythm when the remaining body of the left atrial appendage was in atrial fibrillation or flutter. Electrophysiology confirmed dissociated rhythm within the left atrium. This case emphasizes the need for careful Doppler interrogation of the left atrial appendage and its lobes to look for dissociated atrial rhythm.

Case ReportsUtility of three-dimensional transesophageal echocardiography: anatomy, mechanism, and severity of regurgitation in a patient with an isolated cleft posterior mitral valve.
Echocardiographic assessment of a 72-year-old woman revealed a posterior mitral valve prolapse with an unusual central regurgitation jet. The use of three-dimensional (3D) transesophageal echocardiography elucidated the mismatch between morphologic and color Doppler echocardiographic findings: There was a cleft in the posterior mitral valve in addition to the posterior mitral valve prolapse. This case illustrates that the use of high-quality real-time 3D transesophageal echocardiography (including 3D color Doppler) facilitates the understanding of the anatomy and the mechanism and severity of regurgitation in complex mitral valve pathology and is clearly superior to two-dimensional transesophageal echocardiography alone.
