An 8-Year-Old Boy With a Giant Left Atrium.

Abstract

An 8-year-old boy was referred to our institution because of nausea and vomiting for 1 day. He had also been experiencing shortness of breath for more than 1 year. This symptom had progressed so that he could no longer run or walk upstairs without chest discomfort. There was no associated fever, diarrhea, or coughing. He had a history of heart murmur that was diagnosed in another clinic 4 years ago. Echocardiogram 4 years prior suggested mild to moderate biatrial enlargement with trivial mitral valve regurgitation. He did not go in for any follow-up until this admission. He had no other associated diseases, nor use of medicine.
