Popis: Muscular and cardiac performance was assessed a spirometry and bicycle ergometry in two groups of patients aged 25-55 with mitral xenobioprostheses functioning normally. 36 patients were examined 1-3 years following surgery (group I), 23 patients in 3.5-8 years. Functional results were found not inferior in group II. Stable parameters were more characteristic for patients having preoperative functional classes I-III.
