Invasive Cardiac Procedures in Interstage Single Ventricle Patients in Emergent Hospitalizations.

Single ventricle congenital heart disease (SV CHD) patients are at risk of morbidity and mortality between the first and second palliative surgical procedures (interstage). When these patients present acutely they often require invasive intervention. This study sought to compare the outcomes and costs of elective and emergent invasive cardiac procedures for interstage patients. Retrospective review of discharge data from The Vizient Clinical Data Base/Resource Manager™, a national health care analytics platform. The database was queried for admissions from 10/2014 to 12/2017 for children 1-6 months old with ICD-9 or ICD-10 codes for SV CHD who underwent invasive cardiac procedures. Demographics, length of stay (LOS), complication rate, in-hospital mortality and direct costs were compared between elective and emergent admissions using t test or χ2, as appropriate. The three most frequently performed procedures were also compared. 871 admissions identified, with 141 (16%) emergent. Age of emergent admission was younger than elective (2.9 vs. 4 months p < 0.001). Emergent admissions including cardiac catheterization or superior cavo-pulmonary anastomosis had longer LOS (58.7 vs. 25.8 day, p < 0.001 and 54.8 vs .22.6 days, p < 0.001) and higher costs ($134,774 vs. $84,253, p = 0.013 and $158,679 vs. $81,899, p = 0.017). Emergent admissions for interstage SV CHD patients undergoing cardiac catheterization or superior cavo-pulmonary anastomosis are associated with longer LOS and higher direct costs, but with no differences in complications or mortality. These findings support aggressive interstage monitoring to minimize the need for emergent interventions for this fragile patient population.

Increased risk of intraventricular hemorrhage in low birth weight infants with aortic coarctation.

Objective: To determine if there is an association between aortic coarctation (CoA) and intraventricular hemorrhage (IVH) in low birth weight (LBW) infants that may justify earlier intervention. While there is an increasing number of reports of successful early CoA intervention in LBW infants, there are no data to justify this approach.Material and methods: Retrospective review of the University Health System Consortium Clinical Data Base/Resource Manager, a national hospital discharge database. LBW (≤2 kg) infants, with and without IVH and isolated CoA were identified; IVH was stratified into low (grade 1 or 2) and high (grade 3 or 4) severity. Odds ratios were calculated for any, low and high-grade IVH with CoA.Results: Forty-six thousand and twenty LBW infants were identified; 3716 (8.1%) had IVH, 3001 (81%) with low, and 724 (19%) with high severity. Sixty-four infants had CoA, 13 had associated IVH (10 with low and three with high severity). The odds ratio for any IVH with CoA was 2.91 (95% CI 1.58-5.35), low severity 2.77 (95% CI 1.41-5.46) and high severity 3.45 (95% CI 1.07-11.07).Conclusions: In conclusion, this large retrospective database review found that LBW infants with CoA may be at increased risk of IVH. Further study is needed to determine if earlier catheter- or surgical-based intervention for CoA could reduce the risk of IVH in this population.

Surgical treatment for heart failure: cell-based therapy with engineered tissue.

This review will outline cell-based therapy for heart failure focusing on tissue engineering to deliver cells to the damaged heart. We will present an overview of the central approaches focusing on pluripotent stem cell-derived cells, mechanisms of action, autologous vs. allogeneic cell approaches, immunologic modulation, and safety considerations. We will outline the progress that has been made to-date and define the areas that still need to be investigated in order to advance the field.

Penetrating knitting needle through the mediastinum in a child.

Thoracic injuries are second only to central nervous system injuries as the leading cause of traumatic death in patients of all ages. Penetrating chest injury is very uncommon in children, but it comes with significant morbidity and mortality. Presentation of penetrating thoracic injury in the child is unique with inherent opportunities for learning. The purpose of this case report was to disseminate information regarding rare thoracic trauma in the pediatric patient.
