Measurement of left atrial appendage size by transesophageal echocardiography.

Transesophageal echocardiography (TEE) is the most common imaging method for evaluating left atrial morphology. Recent advances in 64-slice multidetector computed tomography (64-MDCT) allow accurate measurement of left atrial appendage (LAA) volume. The aim of this study was to evaluate the accuracy of LAA sizing by TEE in comparison with 64-MDCT in patients with atrial fibrillation.

Right pulmonary agenesis in an elderly woman complicated by transient ischemic attack.

There are few case reports regarding patients with right lung agenesis living to old age because of both severe mediastinal and cardiac displacements. We report a 61-year-old woman with right pulmonary agenesis complicated by a transient ischemic attack that was evaluated by a three-dimensional reconstruction of helical computed tomography and an echocardiography. This patient was able to survive until old age because she had no critical anomalies in other organs including the heart.
