To assess long-term survival and anticoagulant-related complications after mechanical valve replacement in adolescents with rheumatic heart disease, 88 patients aged 18 years were prospectively followed up for 10 years (404.2 patient-years). There were 58 (65.9%) boys and 30 (34.1%) girls, with a mean age of 15.4 ± 2.1 years. Mitral regurgitation was detected in 39 (44.3%) patients, and both mitral and aortic regurgitation in 15 (17%). Ball valves were inserted in 52 (59.1%) patients, bileaflet valves in 31 (35.2%), and single-disc valves in 5 (5.7%). There were 4 (4.5%) hospital deaths and 11 late deaths. Patient survival at 30 days, 3 months, 1, 5, and 10 years was 95.5%, 93.2%, 87.5%, 82.9%, and 82.9%, respectively. Mechanical valve thrombosis occurred in 4 patients; it was fatal in 3 of them. Three patients died from stroke. Severe hemorrhage required hospital admission in 4 (4.5%) patients. Mechanical valve replacement in adolescents, with careful follow-up and anticoagulation, has acceptable long-term results.
