Abstract: (8662 Views)
In recent socio-economic state it is not possible to have different sets of prosthetic cardiac valves available in the operating room before open-heart surgery for valvular replacement. In this study the diameter of the aortic valve ring measured in 2-D echocardiography was compared with the size of the aortic prosthetic valves implanted for the patients with aortic valvular disease. The purpose was to find a logical correlation to help the surgeons to order the correct size of aortic prosthetic valve in advance of surgery. 26 patients with aortic valve disease were studied from 1972 till 1974 who underwent aortic valve replacement surgery. Now, it is possible to predict the accurate size of aortic mechanical valve prosthesis before surgery
