[Significance of intraoperative measurement of secondary regurgitant tricuspid anulus].
We evaluated the dilated tricuspid anuli (10 cases) during operation by means of direct measurement of the lengths of each leaflet anulus and compared with control group whose anuli were normal (12 cases). The lengths of anterior leaflet anulus and posterior one were dilated significantly more than control group. In this study tricuspid regurgitation was mainly proved to be the dilated anterior leaflet anulus. But it was not identified whether the dilatation of posterior one was contributed to the tricuspid regurgitation with the correlation of cardiac output and right atrial pressure from the underlying data.
