Outcomes of interests were prosthesis failure (stenosis &amp;gt;3.5\u2009m\/s, regurgitation &amp;gt;mild or infective endocarditis) and reintervention.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>The median age at PVR was 19\u2009years. BP and MP were used in 88 (67.2%) and 43 (32.8%) patients, respectively. The median follow-up duration was 7.4\u2009years, and the 10-year survival rate was 96.4%. Risk factors for prosthesis failure were smaller body surface area [hazard ratio (HR) 0.23 per 1\u2009m2, P\u2009=\u20090.047] and smaller prosthesis size (HR 0.73 per 1\u2009mm, P\u2009=\u20090.039). Risk factors for prosthesis reintervention were smaller body surface area (HR 0.11 per 1\u2009m2, P\u2009=\u20090.011) and prosthesis size (HR 0.67 per 1\u2009mm, P\u2009=\u20090.044). Probability of prosthesis failure and reintervention at 10\u2009years were 24.6% (19.5% in BP vs 34.8% in MP, P\u2009=\u20090.34) and 7.8% (5.6% in BP vs 11.9% in MP, P\u2009=\u20090.079), respectively. Anticoagulation-related major thromboembolic events were observed in 4 patients receiving an MP.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>MP might not be superior to BP in terms of prosthesis failure or reintervention.
