Abstract:
BACKGROUND: The aim of this study is to evaluate our clinical experience with the Carbomedics heart valve prosthesis. MATERIAL AND METHOD: Between Aug. 1988 and Dec. 1998, 294 Carbomidics valves were implanted in 235 patients(mitral; 143, mitral and aortic; 59, aortic; 33) The mean age at operation is 40.0+/-12.3 years(range 7 to 68 years); 63.8% (150patients) were woman. Follow up was 97.4% complete and mean follow up time was 5.7years with a total of 1209.2 patient-years. RESULT: The hospital mortality was 8.9%(mitral; was 95.2+/-1.6%(mitral ; 94.9+/-2.1%, mitral and aortic 95.0+/-3.7%, aortic 96.2+/-3.8%). Actual freedom rates from complications(linearized rates in parentheses) were fllowings; thromboembolism 96.2+/-1.5%(0.59%pt-yr), valve thrombosis 96.7+/-1.4%(0.5%/pt/yr), anticoagulant related hemorrhage 98.3+/-1.0%(0.25%/pt-yr), perivalvular leak 99.0+/-1.4%(0.5%/pt-yr), endocarditis 98.7+/-1.0%(0.25%/pt-yr), perivalvular leak 99.0+/-0.7%(0.17%pt-yr), endocarditis 98.7+/-1.0%(0.17%+/-pt-yr) and overall valve-related complications 88.9+/-2.5%(1.68%/pt-yr). CONCLUSION: The clinical performance of the Carbomedics valve was quite satisfactory with a low incidence of valve related mortality and morbidity.
