Interventional Strategies for Children with Progressive Pulmonary Hypertension Despite Optimal Therapy. An Official American Thoracic Society Clinical Practice Guideline.

Background: Pulmonary hypertension in children often progresses despite optimal therapy. This document provides an evidence-based clinical practice guideline for the management of children with progressive pulmonary hypertension despite optimal therapy.

Methods: A multidisciplinary panel identified pertinent questions regarding the management of children with pulmonary hypertension that has progressed despite optimal therapy, conducted systematic reviews of the relevant literature, and applied the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach to develop clinical recommendations.

ACTION-ARC Pediatric and Adult Congenital Heart Disease Ventricular Assist Device Adverse Event Definitions-2023.

Adverse events (AEs) experienced by children and adults with congenital heart disease (CHD) on ventricular assist devices (VADs) are sometimes unique to these populations. The Advanced Cardiac Therapies Improving Outcomes Network (ACTION) and the Academic Research Consortium (ARC) aimed to harmonize definitions of pediatric and CHD AEs for use in clinical trials, registries, and regulatory evaluation. Data from the ACTION registry and adjudication committee were used to adapt general mechanical circulatory support ARC definitions.

Impact of Functional Status at the Time of Transplant on Short-Term Pediatric Lung Transplant Outcomes in the USA.

Purpose: Poor functional status is associated with pediatric lung transplant (LTx) waitlist mortality. We investigate how pre-transplant functional status affects post-LTx survival.

Methods: A retrospective analysis was performed using The United Network for Organ Sharing (UNOS) Registry data.

Diversity and Inclusion Through Collaboration: Co-Producing a Simulation Curriculum to Address Discrimination Against Trainees.

Discrimination toward trainees is a pervasive problem, with surveys showing it is often perpetrated by patients. For several years, residents and faculty in an internal medicine residency have participated in a workshop offering a framework for responding to discriminatory behavior by patients. As part of a larger effort to reinforce this teaching and promote an inclusive environment, the authors pursued a multipronged simulation curriculum that could be incorporated into graduate medical education programs across their institution.

Resuscitation of patients with durable mechanical circulatory support with acutely altered perfusion or cardiac arrest: A scoping review.

Background: There is an increasing prevalence of durable mechanical circulatory supported patients in both the in-and-out of hospital communities. The scientific literature regarding the approach to patients supported by durable mechanical circulatory devices who suffer acutely impaired perfusion has not been well explored.

Methods: The International Liaison Committee on Resuscitation Advanced, Basic, and Pediatric Life Support Task Forces conducted a scoping review of the literature using a population, context, and concept framework.

Outcomes in Children Who Undergo Postcardiotomy Extracorporeal Membrane Oxygenation: A Report From the STS-CHSD.

Background: Children who undergo cardiac surgery may require postcardiotomy extracorporeal membrane oxygenation (ECMO). Although morbidities are considerable, our understanding of outcome determinants is limited. We evaluated associations between patient and perioperative factors with outcomes.

Kinetics of Renin Concentrations in Infants Undergoing Congenital Cardiac Surgery.

Background: Elevated renin has been shown to predict poor response to standard vasoactive therapies and is associated with poor outcomes in adults. Similarly, elevated renin was associated with mortality in children with septic shock. Renin concentration profiles after pediatric cardiac surgery are unknown.

An evaluation of the outcomes associated with peritoneal catheter use in neonates undergoing cardiac surgery: A multicenter study.

Objective: The study objective was to determine if intraoperative peritoneal catheter placement is associated with improved outcomes in neonates undergoing high-risk cardiac surgery with cardiopulmonary bypass.

Methods: This propensity score-matched retrospective study used data from 22 academic pediatric cardiac intensive care units. Consecutive neonates undergoing Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery category 3 to 5 cardiac surgery with cardiopulmonary bypass at centers participating in the NEonatal and Pediatric Heart Renal Outcomes Network collaborative were studied to determine the association of the use of an intraoperative placed peritoneal catheter for dialysis or passive drainage with clinical outcomes, including the duration of mechanical ventilation.

Outcomes of Concomitant Cardiac Surgical Procedures Performed During Pediatric Lung Transplantation in the United States.

Data on concomitant cardiac surgery (CCS) performed during pediatric lung transplantation (LTx) is limited. Therefore, we conducted a multi-institutional analysis to identify the incidence and outcomes of CCS in pediatric (< 18 years) LTx recipients by merging data (2004-2023) from the United Network for Organ Sharing (UNOS) and Pediatric Health Information System (PHIS) databases. Of the total of 596 pediatric LTx recipients, 87 (15%) underwent CCS.

Long-term outcomes following the Ross procedure in neonates and infants: A multi-institutional analysis.

Objectives: For neonates and infants with aortic valve pathology, the Ross procedure historically has been associated with high rates of morbidity and mortality. Data regarding long-term durability are lacking.

Methods: The international, multi-institutional Ross Collaborative included 6 tertiary care centers.

The Burden of Stroke in Neonates Undergoing Congenital Heart Surgery: A Large Multicenter Analysis.

Background: Stroke affects surgical decision making and outcomes of neonatal cardiac surgery (CHS). We sought to assess the burden of stroke in this population from a large multicenter database.

Methods: We analyzed neonates undergoing CHS with cardiopulmonary bypass from the Pediatric Health Information System database (2004-2022).

Predicting Stroke for Pediatric Patients Supported With Ventricular Assist Devices: A Pedimacs Report.

Background: The Pediatric Interagency Registry for Mechanical Circulatory Support (Pedimacs) provides detailed understanding on pediatric patients supported with ventricular assist devices (VADs). We sought to identify important variables affecting the incidence of stroke in pediatric VADs.

Methods: Between 2012 and 2022, 1463 devices in 1219 patients were reported to Pedimacs from 40 centers in patients aged <19 years at their first VAD implantation.

A prospective multicenter feasibility study of a miniaturized implantable continuous flow ventricular assist device in smaller children with heart failure.

Background: There is no FDA-approved left ventricular assist device (LVAD) for smaller children permitting routine hospital discharge. Smaller children supported with LVADs typically remain hospitalized for months awaiting heart transplant-a major burden for families and a challenge for hospitals. We describe the initial outcomes of the Jarvik 2015, a miniaturized implantable continuous flow LVAD, in the NHLBI-funded Pumps for Kids, Infants, and Neonates (PumpKIN) study, for bridge-to-heart transplant.

Flexible bronchoscopy in pediatric lung transplantation.

Pediatric lung transplantation represents a treatment option for children with advanced lung disease or pulmonary vascular disorders who are deemed an appropriate candidate. Pediatric flexible bronchoscopy is an important and evolving field that is highly relevant in the pediatric lung transplant population. It is thus important to advance our knowledge to better understand how care for children after lung transplant can be maximally optimized using pediatric bronchoscopy.

ECMO Bridge to Lung Transplant in Children with Idiopathic Pulmonary Arterial Hypertension.

Idiopathic pulmonary arterial hypertension (IPAH) represents an important clinical indication for lung transplant (LTx) in children. Recent trends show fewer children with IPAH are undergoing LTx nowadays compared to previous time periods, including those with most severe form of the disease. Using the UNOS Registry, we investigated if ECMO at the time of transplant impacts post-transplant survival in children with IPAH.

Transcatheter knocking of a stuck mechanical tricuspid valve.

Immobilisation of mechanical valve leaflets can be a life-threatening complication. In the acute setting, medical therapy can be attempted but is not always successful. We present the first described case of a patient with a mechanical tricuspid valve with recurrent leaflet immobilisation that was able to be mobilised using a transcatheter knocking technique.
