Aortic coarctation is among the most common cardiovascular congenital abnormalities requiring repair after birth. Besides mortality, morbidity remains an important aspect. Accordingly, we reviewed our 20-year experience of aortic coarctation repair by thoracotomy, with emphasis on both short- and long-term outcomes.

From 1995 through 2014, 214 patients underwent coarctation repair via left thoracotomy. Associated arch lesions were distal arch hypoplasia (n = 117) or type A interrupted aortic arch (n = 6). Eighty-four patients had isolated coarctation (group 1), 66 associated ventricular septal defect (group 2), and 64 associated complex cardiac lesions (group 3). Median follow-up was 8.4 years.

There was one (0.5%) procedure-related death. Nine (4.2%) patients died during index admission. In-hospital mortality was 0.7% in group 1 and 2 and 12.5% in group 3 (

< .001). No patient had paraplegia. Actuarial five-year survival was 97.5% in group 1, 94% group 2 and 66% in group 3. Recurrent coarctation developed in 29 patients, all but four (1.8%) successfully treated by balloon dilatation. Freedom from reintervention (dilatation or surgery) at five years was 86%. At hospital discharge, 28 (13.5%) patients were hypertensive. At follow-up, hypertension was present in 11 (5.3%) patients.

Long-term results of aortic coarctation repair by thoracotomy are excellent, with percutaneous angioplasty being the procedure of choice for recurrences. Patient prognosis is dependent on associated cardiac malformations. In this study, the prevalence of late arterial hypertension was lower than previously reported.

Neonates undergoing congenital heart defect repair require optimized nutritional support in the perioperative period. Utilization of a gastrostomy tube is not infrequent, yet optimal timing for placement is ill-defined. The objective of this study was to identify characteristics of patients whose postoperative course included gastrostomy tube placement to facilitate supplemental tube feeding following neonatal repair of congenital heart defects.

A single-institution, retrospective chart review identified 64 consecutive neonates who underwent cardiac operations from 2012 to 2016. Perioperative variables were evaluated for significance in relation to gastrostomy tube placement.

A total of 27 (42%) underwent gastrostomy tube placement. Diagnosis of a genetic syndrome was associated with the likelihood of placement of gastrostomy tube (

= .032), as were patients with single ventricle physiology (

= .0013) compared to those felt to be amenable to eventual biventricular repair. Aortic arch reconstruction is study. Early recognition of such characteristics in future patients may allow for reduced time to gastrostomy tube placement, which in turn may improve perioperative growth and outcomes.

The timing and nature of and risk factors for reoperation after the arterial switch operation in the setting of d-transposition of the great arteries requires further elucidation.

A total of 403 patients who underwent arterial switch operation from 1986 to 2017 were reviewed. Institutional preference was for pulmonary artery reconstruction using a pantaloon patch of fresh autologous pericardium. The targets for coronary artery reimplantation were identified by intermittent root distension. Multivariable analysis was used to identify risk factors for reoperation.

Median follow-up was 8.6 years (interquartile range [IQR] 2-16.9). Pulmonary arterioplasty was the most common reoperation (n = 11, 2.7%) at 3.3 years (IQR 1.4-11.4) postoperatively. Subvalvar right ventricular outflow tract reconstruction (RVOTR) was required in nine (2.2%) patients at 2.5 years (IQR 1.1-5.3) postoperatively. Aortic valve repair or replacement (AVR/r) was required in seven (1.7%) patients at 13.6 years (IQR 10.0-15.8) postoperaroot distension during coronary reimplantation have minimized respective outflow tract reoperations. Certain anatomic subsets carry different risks for late reoperation, and pulmonary artery and/or RVOT reinterventions tend to occur sooner than aortic reinterventions. Special attention to these higher risk subpopulations will be critical to optimizing lifelong outcomes.

The purpose of this study was to assess autograft function after the Ross procedure and to review surgical outcomes associated with autograft reoperations.

This is a retrospective study of patients undergoing the Ross procedure since 1993. Autograft function and autograft reoperation were studied. Autograft failure was defined as more than moderate autograft regurgitation or autograft dilatation to more than 50 mm diameter or z-score of more than +4 in children. One hospital death was excluded from analysis as were patients with unknown late autograft status.

Among 75 patients analyzed, preoperative diagnosis before the Ross procedure included aortic regurgitation in 26, aortic stenosis in 19, combined lesions in 28, and 2 mechanical valve malfunctions. Median age at the Ross procedure was 12.1 (0.4-43.6) years with 44 children less than 15 years old. Six patients had greater than mild autograft regurgitation at post-Ross hospital discharge. During median follow-up of 14.9 years, there were 23 autograft failures. Eighteen autograft reoperations were performed on 17 patients (13 children), including 12 aortic valve replacements, 5 aortic root replacements (including 1 valve-sparing root replacement), and 1 Konno procedure. Freedom from autograft failure and autograft reoperation at 20 years after the Ross procedure was 52.0% and 66.3%, respectively. Multivariate analysis identified greater than mild autograft regurgitation at hospital discharge from Ross procedure as a risk factor for autograft failure (

< .01). All patients who underwent autograft reoperation survived and had good health status at a median of 6.9 years after the reoperation.

The Ross procedure is effective in delaying prosthetic aortic valve replacement, although the time-related risk of autograft failure is a real consideration.

Restenosis after aortic arch reconstruction is a known complication in neonates and infants. Homograft is the most commonly used patch material for aortic arch reconstructions in our center. Since 2014, tissue-engineered bovine pericardium (CardioCel) has been used as an alternative. The aim of our study was to determine whether the choice of material affected the development of restenosis in these patients.

Data of all neonates and infants who underwent aortic arch reconstruction with the use of any patch material between 2005 and 2016 were analyzed. Restenosis was defined by the need for reintervention, either percutaneous or surgical.

Forty-one patients underwent aortic arch repair. Excluding the 30-day mortality, 36 patients represented the study population. At primary repair, the aortic arch was reconstructed with homograft (n = 26) or CardioCel (n = 10). Restenosis was documented during the first year of life in 13 patients Six (23%) patients in the homograft group and seven (70%) patients in the CardioCel group (

= .01). In the homograft group, the median time from operation to first intervention for restenosis was 22.0 (range 14-32) weeks, as compared to 14.0 (range 7-21) weeks in the CardioCel group (

= .04).

We conclude that choice of patch material is likely to be an important determinant for the risk of restenosis needing reintervention following reconstruction of the aortic arch in neonates and infants.

We report two pediatric patients, status-post explantation, who developed true left ventricular apical aneurysms diagnosed by cardiac magnetic resonance imaging. Imaging also suggested laminated thrombus versus postoperative changes which were treated with antiplatelet therapy.Measuring outcomes in pediatric cardiac care has been one of the more widespread, and at the same time controversial and often polarizing, quality improvement initiatives undertaken in the medical field. Risk models, such as the Society of Thoracic Surgeons Congenital Heart Surgery Risk Model, have been developed to account for comorbidities while predicting the expected mortality for a given surgical encounter. In this issue of the journal, Bertsimas and colleagues report on machine learning approaches to predict adverse outcomes in congenital heart surgery using the European Congenital Heart Surgeons Association's congenital database. A head-to-head comparison of machine learning models and the currently available risk models utilizing the same data set are required to better understand the strengths and weaknesses of each of these approaches. Such a focused analysis will shed light on future approaches for risk modeling, which will undoubtedly continue to benefit from the guidance provided by expert clinical intuition.

The purpose was to explore the experience, information and support needs, and decision-making of parents of children with congenital heart disease (CHD), as well as the children/young people themselves, during the COVID-19 crisis.

A survey study of parents of children with CHD, children and young people, capturing experiences, decision-making, information, and support needs during the COVID-19 crisis was conducted. The survey launched for one month (April 9, 2020) during the first infection wave in the United Kingdom and subsequent restriction of free movement under lockdown rules from March 23, 2020, until May 31, 2020.

One hundred eighty-four parents and 36 children/young people completed the survey. Parents were more likely to worry about the virus (86.4%) than children/young people (69.4%), while (89%) parents were more vigilant for symptoms of the virus versus children/young people (69.4%). A thematic analysis of the qualitative comments covered 34 subthemes, forming eight overarching themes Virus-er, were frustrated with the lack of specific and pediatric-focused information and guidance, expressing disappointment with the adult-centric information available. Parents also felt alone, especially with their concerns around the implications of cardiac service suspension and the implication for their child's health. In order to better support children and their families, resources need to be developed to address families' and children/young people's concerns for their health during this pandemic.

Loss of laryngeal function after congenital cardiac surgery causes morbidity and prolongs hospitalization. Early diagnosis of vocal fold immobility (VFI) and referral to pediatric otolaryngology (pOTO) aids in laryngeal rehabilitation. Cyclopamine Understanding the incidence and recovery rates of VFI enables counseling for families of infants undergoing high-risk surgery.

A retrospective chart review from November 2014 to July 2019 of infants postcardiac surgery where the aortic arch or surrounding structures were manipulated and were screened via flexible fiberoptic laryngoscopy (FFL) at a single institution was performed. Patients were divided into five surgical categories Norwood procedure, aortic arch augmentation via median sternotomy, arterial switch operation, coarctation repair via lateral thoracotomy, and cardiac surgeries including ligation of a patent ductus arteriosus (PDA). Patients undergoing isolated PDA ligation were excluded.

One hundred ninety-nine qualifying operations occurred during this period; 28 patients did not undergo FFL before discharge and were excluded from the analysis.
