Intravascular ultrasound (IVUS) has been routinely used in some centers to investigate cardiac allograft vasculopathy in pediatric heart transplant recipients. We present an alternative method using more sophisticated imaging software. This study presents a comparison of this method with an established standard method. All patients who had IVUS performed in 2014 were retrospectively evaluated. The standard technique consisted of analysis of 10 operator-selected segments along the vessel. Each study was re-evaluated using a longitudinal technique, taken at every third cardiac cycle, along the entire vessel...

Patients with hypoplastic left heart syndrome (HLHS) can have associated genetic abnormalities. This study evaluated the incidence of genetic abnormalities among infants with HLHS and the short-term outcomes of this population during the first hospitalization. This is a retrospective analysis of the multi-center Pediatric Heath Information System database of infants with HLHS who underwent Stage I Norwood, Hybrid, or heart transplant during their first hospitalization from 2004 through 2013. We compared clinical data between infants with and without genetic abnormality, among the three most common chromosomal abnormalities, and between survivors and non-survivors...

Prolonged graft ischemia may be a risk factor for early rejection post-HTx, but this has not been well studied in children. Furthermore, factors moderating the association between IT and early rejection have not been investigated. From 2004 to 2012, pediatric HTx recipients (n = 2381) were identified from the UNOS database. A ROC curve determined the optimal IT discriminating patients by the presence of early rejection. Separate univariate analyses identified factors associated with: (i) early (prior to hospital discharge) rejection, and (ii) IT...

The outcomes of pediatric ventricular assist device support in patients with diastolic heart failure have not been well described. This study reviews the North American experience with Berlin Heart EXCOR(®) ventricular assist device implants in children with such physiology. The Berlin Heart clinical database was reviewed. Patients with primary diastolic dysfunction are included in this study. Twenty pediatric patients with restrictive cardiomyopathy (n = 13), hypertrophic cardiomyopathy (n = 3), or congenital heart disease with restrictive physiology (n = 4) who were supported with EXCOR(®) were identified...

BACKGROUND: We hypothesized C1q binding de novo donor specific antibody (DSA) after heart transplant (HT) is a higher risk for development of coronary artery vasculopathy (CAV) in children. METHODS: A retrospective analysis of 127 pediatric heart transplant (HT) recipients transplanted between January 2005 and December 2014 was used to determine complement (C1q)-binding de novo DSA on the outcomes of HT and the ability of the C1q assay to predict CAV development...

BACKGROUND: Children with heart disease may require repeated X-Ray cardiac catheterization procedures, are more radiosensitive, and more likely to survive to experience oncologic risks of medical radiation. Cardiovascular magnetic resonance (CMR) is radiation-free and offers information about structure, function, and perfusion but not hemodynamics. We intend to perform complete radiation-free diagnostic right heart catheterization entirely using CMR fluoroscopy guidance in an unselected cohort of pediatric patients; we report the feasibility and safety...

Orthotopic heart transplantation is a well-established and effective therapeutic option for children with end-stage heart failure. Multiple modalities, including noninvasive cardiac imaging, cardiac catheterization, angiography, and endomyocardial biopsy, are helpful to monitor these patients for graft dysfunction, rejection, and vasculopathy. Because of morbidities associated with invasive monitoring, noninvasive imaging plays a key role in the surveillance and evaluation of symptoms in pediatric transplant recipients...

A VAD is a mechanical pump used to support the functioning of a failing heart. As a pediatric therapy, a VAD is used as a temporary solution for poor heart function, a bridge to transplantation or recovery, or a destination therapy. The goal of this qualitative study was to explore the perspectives of family and professional caregivers of children who are supported by VADs in outpatient settings. Semi-structured interviews were conducted with 22 caregivers of school-aged children discharged home on VAD support...

Success after solid organ transplantation is dependent on the proper balance of immunosuppression to prevent rejection of the allograft while limiting the risk of developing infections and malignancy. We present a 9-year-old girl, remote from transplant, who presented with airway plaque after a change in immunosuppression to include the mTOR inhibitor sirolimus. Differential diagnosis included direct medication side effect, infection, and neoplasia.

Evidence suggests that outcomes in pediatric cardiac surgery are improved by consolidating care into centers of excellence. Our objective was to determine if outcomes are equivalent in patients across a large regional referral base, or if patients from centers without on-site surgery are at a disadvantage. Since 1996, all pediatric cardiac surgery has been offered at one of two centers within the region assessed, with the majority being performed at Stollery Children's Hospital. All patients who underwent a Fontan between 1996 and 2016 were included...

OBJECTIVES: This study sought to determine outcomes of adult recipients of early adolescent (EA) (10 to 14 years) donor hearts. BACKGROUND: Despite a shortage of donor organs, EA donor hearts (not used for pediatric patients) are seldom used for adults because of theoretical concerns for lack of hormonal activation and changes in left ventricular mass. Nonetheless, the outcomes of adult transplantation using EA donor hearts are not clearly established. METHODS: All adult (≥18 years of age) heart transplant recipients in the United Network for Organ Sharing database between April 1994 and September 2015 were eligible for this analysis...

Hemodynamic instability is generally considered as a contraindication to liver splitting, in particular when using an in-situ technique. We describe the cases of two young donors with brain death in whom refractory cardiac arrest and hemodynamic instability were supported by veno-arterial extracorporeal membrane oxygenation (VA-ECMO), allowing uneventful in situ splitting. Two adult and two pediatric liver recipients were successfully transplanted with immediate graft function. Favorable outcomes were also observed for the other transplanted organs, including one heart, two lungs and four kidneys...

OBJECTIVES: We sought to evaluate outcomes of stent implantation (SI) for recurrent coarctation of the aorta (RC) following the Norwood operation. BACKGROUND: RC is common following the Norwood operation. Balloon angioplasty (BA) is standard treatment but may result in unsatisfactory relief of RC. SI may improve RC, but outcome data are limited. METHODS: We performed a multi-center retrospective study of patients who underwent SI for RC between the Norwood operation and Fontan completion...
