A case of cor triatriatum in an eighty-year-old man: transesophageal echocardiographic observation of multiple defects.

An 80-year-old man was admitted to the hospital because of recurrent syncope caused by sick sinus syndrome. Conventional transthoracic echocardiography showed a membranelike echo-dense structure across the left atrium. Subsequently we confirmed the diagnosis of cor triatriatum with multiple defects and shunt flows across the membrane by transesophageal color flow Doppler echocardiography. There were no other associated congenital anomalies. The patient recovered well and was discharged from the hospital after implantation of a permanent VVI pacemaker for sinus node dysfunction. No other cardiac intervention for the cor triatriatum was done except follow-up with echocardiography. About 1 year after discharge, he died of massive cerebral infarction. The cardiac autopsy findings were compatible with the transesophageal echocardiogram. This is a rare case of uncorrected cor triatriatum in an elderly patient.
