A Case of Kommerell's Diverticulum Initially Detected by Transesophageal Echocardiography

Kommerell's diverticulum is a rare congenital disorder characterized by typical right sided aortic arch and aberrant left subclavian artery which are usually detected by accident in asymptomatic patients. However, some of patients complain of severe symptoms caused by compression of the adjacent organs or complicated aortic dissection by the diverticulum. Early detection of the disease can lead to elective surgical correction. In this article, we report a Kommerell's diverticulum case initially detected by transesophageal echocardiography.ope
