title: [Intraoperative and follow-up color Doppler echocardiography for evaluating the surgical results of aortic valvuloplasty in a patient with bicuspid aortic valve].
abstract: A 21-year-old man underwent aortic valvuloplasty for aortic regurgitation due to bicuspid aortic valve. After the initial procedure for valvuloplasty of the anterior cusp, transesophageal color Doppler flow imaging revealed a significant regurgitant jet directed posteriorly as observed preoperatively. After an additional valvuloplastic procedure for the anterior cusp, the size of the regurgitant signal was reduced and directed to the center of left ventricular outflow tract. The surgery was then completed. On the 5th postoperative day, an aortic regurgitant murmur reappeared and color Doppler echocardiography showed a mild but significant regurgitant jet directed toward the interventricular septum, which may have been due to contraction of the anterior cusp treated by valvuloplasty. Aggravation of the aortic regurgitation in the early stage after plastic surgery is important and requires consideration in the intraoperative assessment.
