The biomed caged-ball cardiac valve prosthesis. A study of 120 implants

The purpose of this study was to report our experience with 120 prosthetic valves implanted in 105 patient over an 8 year period. Their preoperative status was compared at an average follow-up period of 4 years (range 1 to 6 years) with the posoperative results. We conclude that the Mexican-made valvels (Biomed) meet the highest international quality standards: they are well tolerated by the patients; their performance is excellent and no postoperative dysfunction of the valves was ever detected. the few complications observed were no different from those reported for foreing ball caged valves. Finally, most of our patients showed a marked improvement postoperatively
