Cardiac Arrest Secondary to Traumatic Aortopulmonary Window During Transcatheter Pulmonary Valve Implantation in Supported Ross.

We present a patient with a supported Ross procedure and severe pulmonary homograft stenosis who developed cardiac arrest while undergoing transcatheter pulmonary valve replacement and was found to have a large iatrogenic aortopulmonary window. Cardiopulmonary resuscitation was initiated followed by covered stent placement, extracorporeal membrane oxygenation support, and ultimately emergent surgery with a good outcome. ().

Identifying self-reported neurocognitive deficits in the adult with congenital heart disease using a simple screening tool.

Objective: Children with congenital heart disease (CHD) and adults with acquired heart disease are at an increased risk of neurocognitive impairment. The objective of this study was to determine the prevalence of self-reported neurocognitive impairment and its risk factors in the adult congenital heart disease (ACHD) population.

Design: The Wisconsin Adult Congenital Heart Disease Program recently began screening ACHD patients to identify those with significant self-perceived neurocognitive impairments.

A retrospective chart review of patients who underwent AR for CCTGA from 2001 to 2015 was performed. The cohort consisted of 15 patients (74% male).

The prevalence of sexual dysfunction and its association with quality of life in adults with congenital heart disease.

Background: The prevalence of sexual dysfunction (SD) and its impact on quality of life (QOL) in adults with congenital heart disease (CHD) is not well known. The aims of this study were to: determine the prevalence of SD, evaluate the risk factors associated with SD, and determine the association between SD and QOL in adults with CHD.

Methods: This was a cross-sectional study of adults (≥18years) with CHD presenting for routine follow-up at our institution.

Center Variability in Timing of Stage 2 Palliation and Association with Interstage Mortality: A Report from the National Pediatric Cardiology Quality Improvement Collaborative.

For infants with single-ventricle lesions with aortic arch hypoplasia, the interstage period from discharge following stage 1 palliation (S1P) until stage 2 palliation (S2P) remains high risk. Significant variability among institutions exists around the timing of S2P. We sought to describe institutional variation in timing of S2P, determine the association between timing of S2P and interstage mortality, and determine the impact of earlier S2P on hospital morbidity and mortality.

Growth Trajectory in Children with Trisomy 21 with and without Atrioventricular Septal Defect.

Objective: Trisomy 21 is associated with poor weight gain and atrioventricular septal defects. The impact of atrioventricular septal defects on weight gain in the setting of Trisomy 21 has not previously been described in the recent era. This study aimed to determine if such an association is present.

The Impact of Obesity on Postoperative Outcomes in Adults with Congenital Heart Disease Undergoing Pulmonary Valve Replacement.

Objective: The impact of obesity on surgical morbidity in adults with congenital heart disease is currently unknown. The aim of our study was to investigate the impact of obesity on postoperative outcomes in adults with congenital heart disease undergoing reoperation for pulmonary valve replacement.

Methods: A retrospective analysis was performed assessing the influence of obesity on surgical outcomes.

Tricuspid repair at pulmonary valve replacement does not alter outcomes in tetralogy of Fallot.

Background: Chronic pulmonary regurgitation after tetralogy of Fallot repair often leads to progressive right ventricle dilation, dysfunction, and frequently, pulmonary valve replacement. For those with significant tricuspid regurgitation at the time of pulmonary valve replacement, it is unknown whether concomitant tricuspid valve repair improves postoperative outcomes.

Methods: This is a retrospective review of patients after tetralogy of Fallot repair who underwent pulmonary valve replacement between 1999 and 2012.

Improving interstage survival after Norwood operation: outcomes from 10 years of home monitoring.

Objective: Infants who undergo Norwood stage 1 palliation (S1P) continue with high-risk circulation until stage 2 palliation (S2P). Routine care during the interstage period is associated with 10% to 20% mortality. This report illustrates the sustained reduction of interstage mortality over 10 years associated with use of home monitoring.

Effect of feeding modality on interstage growth after stage I palliation: a report from the National Pediatric Cardiology Quality Improvement Collaborative.

Objectives: Achieving adequate growth after stage 1 palliation for children with single-ventricle heart defects often requires supplemental nutrition through enteral tubes. Significant practice variability exists between centers in the choice of feeding tube. The impact of feeding modality on the growth of patients with a single ventricle after stage 1 palliation was examined using the multiinstitutional National Pediatric Cardiology Quality Improvement Collaborative data registry.

Feeding dysfunction in children with single ventricle following staged palliation.

Objective: To determine the prevalence of feeding dysfunction in children with single ventricle defects and identify associated risk factors.

Study Design: Patients aged 2-6 years with single ventricle physiology presenting for routine cardiology follow-up at the Children's Hospital of Wisconsin were prospectively identified. Parents of the patients completed 2 validated instruments for assessment of feeding dysfunction.

The spectrum of congenital heart disease and outcomes after surgical repair among children with Turner syndrome: a single-center review.

Turner syndrome (TS), a genetic abnormality affecting 1 in 2,500 people, is commonly associated with congenital heart disease (CHD). However, the surgical outcomes for TS patients have not been well described. This study reviewed the spectrum of CHD in TS at the authors' center.

Extracardiac complications in adults with congenital heart disease.

With the increasing number of adults living with repaired, or unrepaired, congenital heart disease, there is a growing incidence of extracardiac comorbidities. These comorbidities can affect various organ systems in complex ways, and may have a significant impact on a patient's quality of life and survival. Many of these potential complications may go undiagnosed until there is already a significant bearing on the patient's life.

Significant response to oral Etoposide in the treatment of an unresectable cardiac sarcoma.

Primary cardiac sarcomas are rare and carry a poor prognosis. The standard of care is complete resection. Outcomes for patients without complete resection are dismal, and the benefit of adjuvant therapy is uncertain.

Feeding dysfunction in single ventricle patients with feeding disorder.

Purpose: To determine whether caregivers of children with single ventricle heart defects identified as having feeding disorder will report more frequent feeding dysfunction, or maladaptive mealtime behavior and/or interactions, when compared with reference populations.

Methods: As part of routine evaluation, parents of children evaluated at the Feeding, Swallowing, and Nutrition Center at the Children's Hospital of Wisconsin completed previously validated questionnaires to assess feeding dysfunction and parental stress. Parental responses for single ventricle patients were compared with all other children evaluated with a feeding disorder.

Atrial tachyarrhythmias and the Cox-maze procedure in congenital heart disease.

Introduction: Atrial tachyarrhythmias, particularly atrial flutter and fibrillation, are commonly associated with congenital heart disease and are a major cause of morbidity and mortality. The Cox-maze procedure, introduced by Dr. James Cox in 1987, is effective at controlling atrial fibrillation in structurally normal hearts.

Long-term outcomes of the neoaorta after arterial switch operation for transposition of the great arteries.

Background: After the arterial switch operation (ASO) for transposition of the great arteries (TGA), the native pulmonary root and valve function in the systemic position, and the long-term risk for neoaortic root dilation and valve regurgitation is currently undefined. The aim of this study was to determine the prevalence and progression of neoaortic root dilation and neoaortic valve regurgitation in patients with TGA repaired with the ASO.

Methods: Measurements of the neoaortic annulus, neoaortic root at the level of the sinuses of Valsalva, and the degree of neoaortic regurgitation were assessed by serial transthoracic echocardiograms on 124 patients with TGA at a median follow-up of 7.

Myocardial infarction due to a retained epicardial pacing wire.

A 20-year-old man with a temporary epicardial pacing wire retained after infant repair of an atrioventricular septal defect presented with cardiopulmonary arrest. After resuscitation with extracorporeal membranous oxygenation, a coronary angiogram demonstrated a retained epicardial pacing wire compressing the left anterior descending artery and obtuse marginals. Owing to poor prognostic findings on a computed tomography scan of his head, he was terminally withdrawn from mechanical support.

Restrictive lung disease is an independent predictor of exercise intolerance in the adult with congenital heart disease.

Background/objectives: Following repair of congenital heart disease (CHD), adult patients are at risk for reduced exercise capacity. Restrictive lung disease (RLD) may contribute to reduced exercise capacity in this population. The aim of this study was to determine the prevalence of RLD and its impact on exercise tolerance in the adult with CHD.

Predicting left ventricular recovery after replacement of a regurgitant aortic valve in pediatric and young adult patients: is it ever too late?

The management of pediatric and adolescent patients with pure aortic valve regurgitation remains challenging and controversial (Christos et al., Eur J Cardiothorac Surg 17:125-133, 2000; Gersony and Sommerville, ACC Curr J Rev 31:97-98, 2000; Hasaniya et al., J Thorac Cardiovasc Surg 127:970-974, 2004; Sabet et al.
