Native TV failure was defined as significant (\u2265moderate) tricuspid regurgitation and\/or stenosis (mean pressure gradient &amp;gt;5\u2009mmHg). Clinical outcomes, including both TV and right ventricle (RV) size and functions, were evaluated using echocardiography and magnetic resonance imaging.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>The median age and body weight at the time of surgery were 5.4\u2009years and 21.2\u2009kg, respectively. No operative mortality occurred. During the follow-up period, no late mortalities, reoperations or significant TV leaflet-related complications were observed; native TV failure was not observed in any patients, except one with significant tricuspid regurgitation. Biventricular repair was performed in all patients except one who had undergone preoperative one-and-a-half ventricle repair. After TVLA using FAP, the median TV annulus z-score remained within the normal ranges (preoperative \u22120.42 [\u22120.62 to 0.57] versus postoperative \u22120.51 [\u22120.95 to \u22120.13], mean difference: 0.231, 95% confidence interval: \u22120.338 to 0.800, P\u2009=\u20090.377) and tricuspid regurgitation improved significantly (mean difference: 2.111, 95% confidence interval: 1.510\u20132.712, P\u2009=\u20090.040). Postoperative magnetic resonance imaging showed that RV function, and cardiac output were preserved within acceptable ranges.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
