Abstract
Objectives: To evaluate the quality of life and the factors influencing after cardiac valve replacement. Material and methods: After consent, the files of 119 patients, operated in Dakar over a period of 8 years and benefiting from a mechanical prosthesis were analyzed. Clinical, ultrasound and quality of life (modified SF 36), before and after surgery were collected. Results: The median age was 30 years (range 11-59), 69 % were women. Of the 119 patients, (including), 19 % were aortic and 71 % were mitral valve and 10% were double valves replacements. After a mean follow-up of 78 months, 6 patients had any oral anticoagulation. There were 24 % minor accidents and 2.5 % major accidents in patients treated by oral anticoagulants. Eight patients /82 had at least one pregnancy (10 %) of which 7 were completed. During postoperative follow-up, a significant decrease in left ventricular dimensions (p = 0.01) and pulmonary arterial pressures (p = 0.06) as well as decreased tricuspid valve regurgitation were observed (IT > II: 50 % before surgery, 26 % after surgery). Mean quality of life score before surgery was 52/80 points versus 72/80 points after. The improvement of the score was better marked for the MVR (51 before surgery, 72 after surgery) than for the AVR (55 before surgery, 71 after surgery). Persistence of ACFA, IT ≥ II and PAPS ≥ 40 mmHg negatively influenced the quality of life score. Conclusion: This study on the Senegalese population makes it possible to see the influence of mechanical heart valve replacement on the quality of life of the patients and factors that can affect it. Key words: quality of life, heart surgery
