Journal ArticleDOI
Contemporary Outcomes after the Fontan Procedure: A Pediatric Heart Network Multicenter Study
Page A.W. Anderson,Lynn A. Sleeper,Lynn Mahony,Steven D. Colan,Andrew M. Atz,Roger E. Breitbart,Welton M. Gersony,Dianne Gallagher,Tal Geva,Renee Margossian,Brian W. McCrindle,Stephen M. Paridon,Marcy L. Schwartz,Mario Stylianou,Richard V. Williams,Bernard J. Clark +15 more
TL;DR: Moves of ventricular systolic function and functional health status, although lower on average in the cohort compared with control subjects, were in the majority of subjects within 2 standard deviations of the mean for control subjects.
Journal ArticleDOI
A Cross-Sectional Study of Exercise Performance During the First 2 Decades of Life After the Fontan Operation
Stephen M. Paridon,Paul Mitchell,Steven D. Colan,Richard V. Williams,Andrew D. Blaufox,Jennifer S. Li,Renee Margossian,Seema Mital,Jennifer L. Russell,Jonathan Rhodes +9 more
TL;DR: Higher O(2) pulse is associated with better exercise performance, whereas adolescence and male gender are associated with decreased performance compared with healthy subjects, in Fontan patients.
Journal ArticleDOI
Enalapril in Infants With Single Ventricle Results of a Multicenter Randomized Trial
Daphne T. Hsu,Victor Zak,Lynn Mahony,Lynn A. Sleeper,Andrew M. Atz,Jami C. Levine,Piers Barker,Chitra Ravishankar,Brian W. McCrindle,Richard V. Williams,Karen Altmann,Nancy S. Ghanayem,Renee Margossian,Wendy K. Chung,William L. Border,Gail D. Pearson,Mario Stylianou,Seema Mital +17 more
TL;DR: Administration of enalapril to infants with single-ventricle physiology in the first year of life did not improve somatic growth, ventricular function, or heart failure severity, and the results of this randomized trial do not support the routine use of enAlapril in this population.
Journal ArticleDOI
Longitudinal Outcomes of Patients With Single Ventricle After the Fontan Procedure.
Andrew M. Atz,Victor Zak,Lynn Mahony,Karen Uzark,Nicholas Dagincourt,David J. Goldberg,Richard V. Williams,Roger E. Breitbart,Steven D. Colan,Kristin M. Burns,Renee Margossian,Heather T. Henderson,Rosalind Korsin,Bradley S. Marino,Kaitlyn Daniels,Brian W. McCrindle +15 more
TL;DR: Interim transplant-free survival over 12 years in this Fontan cohort was 90% and was independent of ventricular morphology; exercise performance decreased and was associated with worse functional health status; future interventions might focus on preserving exercise capacity.
Journal ArticleDOI
Comparison of echocardiographic and cardiac magnetic resonance imaging measurements of functional single ventricular volumes, mass, and ejection fraction (from the Pediatric Heart Network Fontan Cross-Sectional Study).

TL;DR: Echocardiographic and CMR measurements ofFSV EF demonstrate similar interobserver reproducibility, whereas measurements of FSV mass and LV diastolic volume are more reproducible by CMR.
