Use of the Medtronic Freestyle valve as a right ventricular to pulmonary artery conduit.

摘要: Abstract Background . We have used the Medtronic Freestyle bioprosthesis as a right ventricular to pulmonary artery conduit recently in an attempt overcome some of problems associated with homografts and stented xenografts. The aim this study was review performance prosthesis. Methods Prospectively collected data for patients having bioprostheses implanted were reviewed assess clinical outcome echocardiographic results. Results Thirteen aged 13 days 22.5 years (median, 7.9 years) underwent either primary repair (n = 5) or change 8) using bioprosthesis. One neonate truncus arteriosus died postoperatively hypertension. explanted 27 months after neonatal arteriosus. There has been no incidence significant prosthetic regurgitation, thromboembolism, endocarditis at mean follow-up 10.1 (range, 2 weeks 29 months). Conclusions valve is reliable substitute short term. Early results justify continued use device setting close follow-up.
