Abstract The initial “Frontiers in Fontan Failure” conference in 2015 in Atlanta, Georgia, provided an
opportunity for experts in the field of pediatric cardiology and adult congenital heart disease
to focus on the etiology, physiology, and potential interventions for patients with “Failing
Fontan” physiology. Four types of “Fontan Failure” were described and then published by Dr
Book et al. The acknowledgment that even Dr Fontan himself realized that the Fontan proce‐
dure “imposed a gradually declining functional capacity and premature late death after an initial
period of often excellent palliation.” The purpose of the second “Frontiers in Fontan Failure”

Abstract The purpose of this study was to determine the optimal age for performing Fontan
operation using data from the National Inpatient Sample. Our results showed that
although the Fontan operation was most commonly performed at age 2 in the United
States, age 3 is the optimum age for this procedure as evident by lower rate of in‐hospital mortality, procedure‐related complications, and rate of nonroutine home discharge when procedure is performed at age 3 years. More >

Abstract Objective: Gated cardiac MRI offers the most detailed and accurate noninvasive
method of assessing cardiac anatomy, particularly in patients with complex congenital
heart disease. The proposed benefits of using cMRI as a routine screening tool in the
Fontan population include early recognition of asymptomatic, postoperative anatomic
and physiologic changes. In 2011, we therefore instituted at our center a recommended
practice of cMRI screening in patients with Fontan physiology at 3 and 8 years postFontan operation. The purpose of this study was to determine the impact of this standardized practice of cMRI screening on the clinical management of a Fontan
population.

Abstract Aim: The Fontan circulation is highly dependent on ventilation, improving pulmonary
blood flow and cardiac output. A reduced ventilatory function is reported in these
patients. The extent of this impairment and its relation to exercise capacity and qual‐
ity of life is unknown and objective of this study.
Methods: This multicenter retrospective/cross‐sectional study included 232 patients
(140 females, age 25.6 ± 10.8 years) after Fontan palliation (19.8% atrioventricular
connection; 20.3% atriopulmonary connection; 59.9% total cavopulmonary connec‐
tion). Resting spirometry, cardiopulmonary exercise tests, and quality‐of‐life assess‐
ment (SF‐36 questionnaire) were performed between 2003 and 2015.

Abstract Dysautonomia is an increasingly recognized yet still poorly understood disease within
the field of pediatrics. Symptoms, including dizziness, headaches, fatigue, joint pain,
anxiety, and intolerance of heat or cold, are often significant and difficult to sort,
especially in terms of their relation to each other. This often leads to referral to multiple subspecialists, who then proceed to treat seemingly familiar symptoms in kind.
In the authors’ experience, this leads to more frustration on the part of the patients
and their physicians when symptom improvement does not follow (or can even
worsen). On the other hand, by understanding the pathophysiology, treatment… More >

follow‐up outcomes for right anterolateral minithoracotomy (RAMT) vs full sternot‐
omy (FS) in surgical aortic valve replacement (AVR) among adolescents with bicuspid
aortic valve (BAV).
Methods: Patients were retrospectively enrolled from January 2008 to December
2017. Inclusion criteria were patients with BAV who had to undergo to AVR. They
were divided in two groups: RAMT and FS. The choice of RAMT was based on indi‐
vidual surgeon’s preferences or when expressly requested by patient that was in‐
formed of nonconventional approach.

Abstract Objective: The recognition of fluid retention is critical in treating heart failure (HF).
Bioelectrical impedance analysis (BIA) is a well-known noninvasive method; however,
data on its role in managing patients with congenital heart disease (CHD) are limited.
Here, we aimed to clarify the correlation between BIA and HF severity as well as the
prognostic value of BIA in adult patients with CHD.
Design: This prospective single-center study included 170 patients with CHD admitted
between 2013 and 2015. We evaluated BIA parameters (intra- and extracellular water,
protein, and mineral levels, edema index [EI, extracellular water-to-total body water

Abstract Objective: The number of adults with congenital heart disease (CHD) has increased
substantially because of medical advances that are extending life expectancy beyond
childhood. A historical investigation is timely not only because of this significant demographic shift, but also because stakeholder engagement is increasingly important
in shaping research directions. The study questions were: From the perspective of
stakeholders, what is known about the medical treatment for the adult CHD cohort
in Canada and how has it changed over time?

Abstract Background: High levels of vasoactive inotrope support (VIS) after congenital heart
surgery are predictive of morbidity in pediatric patients. We sought to discern if this
relationship applies to adults with congenital heart disease (ACHD).
Methods: We retrospectively studied adult patients (≥18 years old) admitted to the
intensive care unit after cardiac surgery for congenital heart disease from 2002 to
2013 at Mayo Clinic. Vasoactive medication dose values within 96 hours of admis‐
sion were examined to determine the relationship between VIS score and poor out‐
come of early mortality, early morbidity, or complication related morbidity.

Abstract Background: Traditional indices to evaluate biventricular (BiV) pacing are load dependent, fail to
assess dynamic changes, and may not be appropriate in patients with congenital heart disease
(CHD). We therefore measured the force‐frequency relationship (FFR) using tissue Doppler‐de‐
rived isovolumic acceleration (IVA) to assess the dynamic adaption of the myocardium and its vari‐
ability with different ventricular pacing strategies.
Methods: This was a prospective pilot study of pediatric and young adult CHD patients with
biventricular or multisite pacing systems. Color‐coded myocardial velocities were recorded at
the base of the systemic ventricular free wall. IVA was calculated at resting heart rate… More >

Abstract Background: Catheter ablation is commonly performed to treat atrial arrhythmias in
adult congenital heart disease (ACHD). Despite the frequency of ablations in the
ACHD population, predictors of recurrence remain poorly defined.

Abstract Objective: Maternal anti-Ro/SSA and anti-La/SSB antibodies can lead to fetal complete heart block (CHB). Current guidelines recommend weekly echocardiographic
screening between 16 and 28 weeks gestation. Given the cost of screening and the
rarity of conduction abnormalities in fetuses of mothers with low anti-Ro levels
(<50 U/mL), we sought to identify a strategy that optimizes resource utilization.
Design: Decision analysis cost-utility modeling was performed for three screening
paradigms: “standard screening” (SS) in which mid-gestation mothers are screened
weekly, “limited screening” (LS) in which fetal echocardiograms are avoided unless
the fetus develops bradycardia, and “targeted screening by maternal antibody level”

Abstract Introduction: In the pediatric Appropriate Use Criteria (AUC), abnormal electrocardiogram (ECG) in an asymptomatic patient has been rated as an “Appropriate” indication for transthoracic echocardiogram (TTE). We hypothesized that the yield of

American Heart Association guidelines recommend systematic developmental screening for

Abstract Ligation of a hemodynamically significant ductus arteriosus results in significant
changes in loading conditions which have predictable consequences. Postligation
cardiac syndrome, defined as hypotension requiring inotropic support and failure of
oxygenation and ventilation, may occur 6‐12 hours following ligation due to left ven‐
tricular systolic and diastolic failure, respectively. Afterload is the primary driver of
this decompensation. In this review, we describe the pathophysiological changes in
loading conditions associated with postligation cardiac syndrome and other contrib‐
utors to cardiovascular dysfunction following ductal ligation. We present strategies
for perioperative optimization and a physiology‐based algorithm for postoperative
management guided by targeted neonatal… More >
