title: The Hall-Kaster disc valve prosthesis: clinical and hemodynamic observations in patients undergoing aortic valve replacement.
abstract: In a series of 113 patients receiving Hall-Kaster aortic valve prostheses intraoperative- and postoperative hemodynamic studies revealed favourable utilization of the valve orifice for transvalvar forward flow. Angiography demonstrated optimal disc opening and minor valvar regurgitation. A significant clinical improvement and improvement of left ventricular function were observed postoperatively.
