“…Currently, the first therapeutic choice for treating critical pulmonary stenosis is percutaneous pulmonary valvuloplasty. 1 Surgical pulmonary valvuloplasty was the only option for this case due to complex anatomy or hemodynamic instability. A median sternotomy is the standard approach; however, this longitudinal midline incision is invasive and leaves a significant scar.…”

Over the last few decades, due to evolving surgical techniques and medical management, there has been a significant decrease in the rate of mortality and complications for neonates born with critical pulmonary valve stenosis. Median sternotomy is the standard approach; however, this longitudinal midline incision is invasive and leaves a significant scar. A right mini thoracotomy approach to this surgical repair decreases recovery time and the chance of possible future psychological distress from a visible median sternotomy scar. This is the first article to describe a right mini thoracotomy approach for critical pulmonary stenosis during the neonatal period.

“…In contrast, the concept of growth accommodation via balloon dilation of a polymeric valve is based on technologies with greater acceptance in current clinical practice. Catheter‐based interventions already represent the standard of care for treating valvular disease, such as balloon valvuloplasty for valve stenosis [ 85,86 ] and post‐implantation balloon dilation of transcatheter valves. [ 87 ] Biostable polymeric valves have also been successfully translated to the clinic—ePTFE valves are commonly assembled in the operating room and then implanted with excellent results.…”

Currently available heart valve prostheses have no growth potential, requiring children with heart valve diseases to endure multiple valve replacement surgeries with compounding risks. This study demonstrates the in vitro proof of concept of a biostable polymeric trileaflet valved conduit designed for surgical implantation and subsequent expansion via transcatheter balloon dilation to accommodate the growth of pediatric patients and delay or avoid repeated open‐heart surgeries. The valved conduit is formed via dip molding using a polydimethylsiloxane‐based polyurethane, a biocompatible material shown here to be capable of permanent stretching under mechanical loading. The valve leaflets are designed with an increased coaptation area to preserve valve competence at expanded diameters. Four 22 mm diameter valved conduits are tested in vitro for hydrodynamics, balloon dilated to new permanent diameters of 23.26 ± 0.38 mm, and then tested again. Upon further dilation, two valved conduits sustain leaflet tears, while the two surviving devices reach final diameters of 24.38 ± 0.19 mm. After each successful dilation, the valved conduits show increased effective orifice areas and decreased transvalvular pressure differentials while maintaining low regurgitation. These results demonstrate concept feasibility and motivate further development of a polymeric balloon‐expandable device to replace valves in children and avoid reoperations.

“…8 In neonates, less invasive interventions are preferred because open heart surgery cannot be performed at all centres and is associated with a high mortality risk, especially in developing countries. 9 Currently, percutaneous cardiac interventions afford higher success rates with lower morbidity compared with surgery in newborns in poor general condition. 10 This study retrospectively evaluated the demographic characteristics, diagnoses, procedures, complications and early outcomes of newborns who underwent interventional cardiological procedures between January 2014 and December 2016 in a neonatal intensive care unit (NICU) at a tertiary care centre in Turkey.…”

Objective Percutaneous cardiac catheterization has been used as a diagnostic tool and as a therapeutic option in neonates with congenital heart disease (CHD). This study aimed to evaluate the procedural and short-term follow-up data of newborns who underwent cardiac catheterization procedures. Methods This retrospective study reviewed demographic, diagnostic and clinical data from the medical records of newborns who underwent percutaneous transcatheter interventions to treat CHD. Results Forty-six newborns were included in the study. The median gestational week and weight were 35.0 weeks and 2723 g, respectively. The median time to the procedure was 7.6 days. Aortic and pulmonary balloon valvuloplasty, ductal stenting, atrial balloon/blade septostomy and coronary fistula embolization procedures were used. The overall success rate was 73.9% (34 of 46 patients) with a complication rate of 28.3% (13 of 46 patients). Eleven patients (23.9%) underwent reinterventions after initial catheterization. Five patients (10.9%) died in the first 48 h after their procedures. Conclusions Interventional cardiological procedures applied during the neonatal period provide alternative life-saving methods to surgery, especially in developing countries where surgical outcomes are poor and newborn mortality rates are high.
