Development and manufacture of prosthetic cardiac valves. Mexican cardiac valvular prostheses

A brief account of the history of the development of cardiac valvular prostheses is given. The use of these devices is analyzed. The authors describe the successive stages of the use of the various types of mechanical prosthetic valves with special reference to the experience in Mexico. They refer to the manufacture of testing and clinical results with the Biomed valves made in Mexico. It is concluded that these devices meet the highest standards and that, given their low cost, should be the option of choice for valve implantation in cardiac patients in our country.
