BACKGROUND: This study was designed to evaluate patients aged less than 40 years implanted with tissue heart valves with respect to survival, thromboembolism, structural degeneration and quality of life.
METHODS: Between January, 2000 and December, 2016, 132 patients (51 males) with rheumatic heart disease underwent mitral valve replacement using Carpentier-Edwards, perimount, pericardial bioprostheses. The patients' ages ranged between 12 and 39 years (mean±SD 30.12±5.51 years).
RESULTS: The hospital and late mortality were 1.5% and 1.5% respectively. The total cumulative follow-up period was 1330.98 patient-years with a mean of 124.78±50.3 months (range, 1-204 months). The actuarial survival and actuarial event-free survival at 204 months was 96.9% (±0.01%) and 93.4%(±0.03%) respectively. There was one episode of thromboembolism (0.32 events per 100 patient years). Six (4.7%) patients underwent redo mitral valve replacement for severe bioprosthetic degeneration with stiffening and calcification using a Medtronic mechanical prosthesis (Medtronic Open Pivot, MN, USA).
CONCLUSIONS: We conclude that Carpentier-Edwards perimount pericardial prosthesis provides satisfactory clinical performance in a young population with a low risk of degeneration and other valve-related events.
