Abstract
A 23-year-old man had had a fever of unknown origin for a month. Aggravation of shortness of breath brought him to our hospital. After a close inspection, transthoracic and esophageal echocardiography (TEE) showed severe aortic valve regurgitation (AR) with vegetation extending for 25mm. The valve was bicuspid and the vegetation was on the left side valve. TEE also revealed a streak of mitral valve regurgitation (MR). In spite of continuous antibiotic therapy, congestive heart failure developed with progressive MR, so we performed an emergency operation. The aortic valve was bicuspid composed of an agglutinated left and non-coronary cusp, and 15×30mm vegetation was attached on the left. Checking the mitral valve after resection of aortic valve, we found a perforation 3mm in size at the center of the anterior mitral leaflet. After resection of the infected area, we repaired it with a Xenomedica patch 10mm in size through the aortic orifice. Two abscesses located beneath both leaflets were eradicated and finally aortic valve replacement was done with an SJM 23.
