ANOMALOUS CORONARY ARTERY
Anomalous aortic origin of coronary artery biomechanical modeling: Toward clinical application
Mauro Lo Rito, MD, Rodrigo Maximiliano Romarowski, Eng PhD, Antonio Rosato, Eng, Silvia Pica, MD, Francesco Secchi, MD, PhD, Alessandro Giamberti, MD, Ferdinando Auricchio, Eng PhD, Alessandro Frigiola, MD, Michele Conti, Eng PhD
Computational simulations show that coronary lumen of anomalous aortic origin lack appropriate expansion during effort.

Commentary: Modeling anomalous coronaries: Hard to predict the predictability of prediction
Ronald K. Woods, MD, PhD
A creative model to predict the behavior of anomalous coronaries may enhance prediction of clinical behavior, but predictability remains to be verified.
Commentary: Are we there yet?
Camille L. Hancock Friesen, MD, Tarique Hussain, MD, PhD
Personalized medicine is coming closer to reality in congenital cardiac surgery as a result of computational modeling.
Commentary: Anomalous coronary arteries and car crash testing
Jacob R. Miller, MD, Pirooz Eghtesady, MD, PhD
Structural finite element analysis allows for the dynamic evaluation of an anomalous coronary arteries. It may, eventually, help determine if surgical intervention is necessary.

ANOMALOUS CORONARY ARTERY: INVITED EXPERT TECHNICAL REVIEW
Current surgical management of anomalous aortic origin of a coronary artery
Edward Buratto, MBBS, PhD, Igor E. Konstantinov, MD, PhD, FRACS
Surgery for anomalous aortic coronary artery carries a low risk of mortality. However, there is a risk of aortic regurgitation and new ischemia, which must be considered when counseling patients.
MITRAL VALVE
Revisiting prosthesis choice in mitral valve replacement in children: Durable alternatives to traditional bioprostheses
Perry S. Choi, BA, Lynn A. Sleeper, ScD, Minmin Lu, MS, Patrick Upchurch, MD, Christopher Baird, MD, Sitaram M. Emani, MD
Use of mechanical or stented bovine jugular vein valve for mitral valve replacement in children yields longer durability compared with fixed-diameter bioprosthetic alternatives.
Commentary: Taking innovation to heart in pediatric mitral valve replacement
Matteo Trezzi, MD
In recent years, adaptation of the Melody valve for pediatric MVR has been introduced and results are promising when compared with currently available prosthesis.
Commentary: And the winner is…
Carl L. Backer, MD
In a large series of infants and children undergoing mitral valve replacement, the best performance of an implanted valve was achieved by mechanical valves and stented bovine jugular vein valves.
Commentary: Mitral valve prosthesis in children: Is it the time to change our beliefs and practice?
Mauro Lo Rito, MD, Alessandro Frigiola, MD, Alessandro Giamberti, MD
Mitral valve replacement in children carries a high burden of reoperation, death, and adverse events. The perfect prosthesis currently does not exist, but valid alternative solutions are available.
TRUNCAL VALVE
Truncus arteriosus repair: A 40-year multicenter perspective
Phillip S. Naimo, MD, Douglas Bell, MBBS, MS, Tyson A. Fricke, MBBS, Yves d'Udekem, MD, PhD, FRACS, Christian P. Brizard, MD, Nelson Alphonso, MBBS, MS, FRACS, Igor E. Konstantinov, MD, PhD, FRACS
Neonates and coronary anomalies pose significant challenges to truncus arteriosus repair. Survival beyond the first year is associated with excellent outcomes.
Commentary: Outcomes of truncus arteriosus repair: Insights from time and numbers
Christoph P. Hornik, MD, PhD, MPH
Large patient cohorts with complete long-term follow-up provide invaluable information to inform congenital cardiac care. Novel strategies to scale up complete long-term follow-up should be pursued.
Commentary: Truncus among us
Christopher E. Mascio, MD
TA has been repaired successfully in the neonate for 30 years. Advances in imaging, operative techniques, and perioperative care have contributed to improving morbidity and mortality.
AORTIC VALVE: INVITED EXPERT REVIEW
Aortic valve surgery in children
Aortic valve repair in infants is the best option, whereas it gives similar outcomes to the Ross operation in older children.
TRACHEA: EVOLVING TECHNOLOGY
Preclinical evaluation of a pediatric airway stent for tracheobronchomalacia
Abhijit Mondal, PhD, Junhyoung Ha, PhD, Vickie Y. Jo, MD, Fei-Yi Wu, MD, Aditya K. Kaza, MD, Pierre E. Dupont, PhD
Preclinical testing of a new airway stent system that minimizes foreign body reaction, promotes mucus flow, and enables atraumatic removal.
Commentary: Malacia got you down? Unwind with a helical stent
Douglas M. Overbey, MD, Joseph W. Turek, MD, PhD, Nicholas D. Andersen, MD
The authors describe preclinical testing of a novel pediatric airway stent with a helical design that allows for minimal surface contact with the tracheal wall and atraumatic removal.
Commentary: Toward a more ideal pediatric airway stent for tracheobronchomalacia
Roosevelt Bryant III, MD
The helical Niti-S airway stent shows promise as a more ideal prosthesis for the management of tracheobronchomalacia.
