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.
Background: The GORE CARDIOFORM ASD Occluder (GCA, W. L. Gore & Associates) was approved in 2019 for ostium secundum atrial septal defect (ASD) closure.

We performed a multicenter, cross-sectional evaluation of a previously assembled cohort of infants with sTOF who underwent initial intervention at ≤ 30 days of age, between 2005 and 2017. Eligible patients' parents/guardians completed an age-appropriate Pediatric Quality of Life Inventory, a Pediatric Quality of Life Inventory Cardiac Module Heart Disease Symptoms Scale, and a parental survey.

Background: A bioprosthetic valve is recommended for women of childbearing age who require cardiac valve replacement in order to minimize the risk of blood clot formation. However, it should be noted that compared to mechanical valves, bioprosthetic valves have a shorter lifespan and a higher likelihood of requiring reoperation during follow-up. To assess the long-term postoperative results, including the incidence of structural valve deterioration (SVD) and other clinical outcomes, in female patients aged 50 years and younger who underwent BalMedic bovine pericardial bioprosthetic valve replacement, a multicenter retrospective study was implemented in China.

The mechanism of fixation for the Alterra prestent is radial force from the self-expanding stent frame, combined with a unique set of flared "tines" that protrude from both ends of the stent.
Aims, Methods, And Results: In this report, we describe 6 patients who underwent uncomplicated transcatheter pulmonary valve replacement with an Alterra adaptive prestent and SAPIEN 3 valve and had surveillance chest computed tomography (CT) scans performed 1 day to 21 months after implant.

Pediatric pulmonary vein stenosis (PVS) is often progressive and treatment-refractory, requiring multiple interventions. Hybrid pulmonary vein interventions (HPVIs), involving intraoperative balloon angioplasty or stent placement, leverage surgical access and customization to optimize patency while facilitating future transcatheter procedures. We review our experience with HPVI and explore potential applications of this collaborative approach.

Methods: We reviewed 22 patients with aforementioned anatomy and PA centralization from 1995 to 2023, excluding those with biventricular repair.
Results: Median age at centralization was 9 days (minimum-maximum, 0 days-2 years).
Background: Anatomic selection for Harmony valve implant is determined with the aid of a screening report and perimeter plot (PP) that depicts the perimeter-derived radius along the right ventricular outflow tract (RVOT) and projects device oversizing. The PP provides an estimation of suitability for implant, but its sensitivity as a screening method is unknown. This study was performed to describe anatomic features and outcomes in patients who underwent Harmony TPV25 implant despite a PP that predicted inadequate oversizing.

Pulmonary embolism presents in various ways depending on the patient, the size of the embolism, and the comorbidities. Treatment decisions are often driven by the severity of the presentation and hemodynamic effects; severe presentations require more invasive and aggressive treatment.

Background: The modified Blalock-Taussig-Thomas shunt is the gold standard palliation for securing pulmonary blood flow in infants with ductal-dependent pulmonary blood flow. Recently, the ductus arteriosus stent (DAS) has become a viable alternative.
Methods And Results: This was a retrospective multicenter study of neonates ≤30 days undergoing DAS or Blalock-Taussig-Thomas shunt placement between January 1, 2017 and December 31, 2020 at hospitals reporting to the Pediatric Health Information Systems database.
