TL;DR: MVR may be an appropriate strategy for children <5 years old despite the risk of second MVR in the youngest patients in whom the smallest prostheses are used, according to the experience of the Pediatric Cardiac Care Consortium.
Abstract: Background— Prosthesis survival, growth, and functional status after initial mechanical mitral valve replacement (MVR) in children <5 years of age are poorly defined Methods and Results— The experience of the Pediatric Cardiac Care Consortium (45 centers, 1982 to 1999), which included 102 survivors after initial MVR, was analyzed Median follow-up: 60 years (interquartile range: 30 to 106 years; 96% complete) Twenty-nine survivors had undergone a second MVR at an interval of 48±38 years after initial MVR Reasons for second MVR were prosthetic valve stenosis 24 (83%), thrombosis 4 (14%), and endocarditis 1 (3%) For those who had second MVR, prosthesis sizes were: first MVR 19±2 mm and second MVR 22±3 mm, and their body weight increased from 74±28 kg to 168±105 kg To identify risk factors for having a second MVR, the 29 second MVR survivors were compared with the 73 who did not have a second MVR on first-MVR demographic and perioperative variables By univariate analysis, patients with shorter
