Background: Lung transplantation is an advanced medical therapy reserved for patients with end-stage lung disease. Relative to other solid organ transplants, lung transplantation in children is infrequently performed. The most common etiologies for pediatric lung transplantation worldwide are cystic fibrosis, pulmonary hypertension, and children’s interstitial lung disease.

Objectives: To describe our experience in pediatric lung transplants at Israel's largest transplant center.

Methods: We performed a retrospective review of all pediatric lung transplantations conducted in our center since 1997. We recorded demographic characteristics, indication for transplantation, clinical and laboratory parameters, post-transplant complications, and survival rates.

Results: Of 965 lung transplants, 29 (3.0%) were pediatric patients who underwent lung or heart-lung transplants for end-stage lung disease. Age at transplantation ranged from 2 to 18 years, with a median of 14.0 years (IQR 11–15). Primary etiologies for transplantation were cystic fibrosis (44%), pulmonary hypertension (17%), and children’s interstitial lung disease (10%). Survival at 1, 5, 10, and 15 years post-transplant were 90%, 65%, 55%, and 20%, respectively, which is consistent with data reported by pediatric lung transplantation registries. The primary cause of mortality post-transplant was chronic lung allograft dysfunction. Four patients (13.8%) underwent re-transplant. There was no association between survival and transplant indication, nor between survival and type of procedure (lung vs. heart-lung transplant).

Conclusions: The short- and long-term outcomes from our program are consistent with published registry data. These outcomes may reflect the benefits of a centralized pediatric lung transplant program, supported by a multidisciplinary team trained in high-capacity international centers.

Background: Ventricular assist devices (VADs) play a critical and increasing role in treating end-stage heart failure in pediatric patients. A growing number of patients are supported by VADs as a bridge to heart transplantation. Experience with VADs in the pediatric population is limited, and experience in Israel has not been published.

Objectives: To describe this life-saving technology and our experience with VAD implantation in children with heart failure, including characteristics and outcomes.

Methods: We conducted a retrospective chart review of all patients who underwent VAD implantation at Schneider Children's Medical Center from 2018 to 2023.

Results: We analyzed results of 15 children who underwent VAD implantation. The youngest was 2.5 years old and weighed 11 kg at implantation. In eight patients, HeartMate 3, a continuous-flow device, was implanted. Seven patients received Berlin Heart, a pulsatile-flow device. Three children required biventricular support; 11 underwent heart transplants after a median duration of 169 days. Two patients died due to complications while awaiting a transplant; two were still on VAD support at the time of submission of this article. Successful VAD support was achieved in 86.6% of patients. In the last 5 years,79%  of our heart transplant patients received VAD support prior to transplant.

Conclusions: Circulatory assist devices are an excellent bridge to transplantation for pediatric patients reaching end-stage heart failure. VADs should be carefully selected, and implantation techniques tailored to patient's weight and diagnosis at a centralized pediatric cardiac transplantation center. Israeli healthcare providers should be cognizant of this therapeutic alternative.

Background: neonatal cardiac surgery has evolved over the last 50 years with a large percentage of the patients achieving complete physiological repair in the neonatal period. The remaining patients achieve staged palliation with an increasing amount of success. 

Objectives: To report our experience with 1000 neonatal cardiac surgical procedures performed in the last 10 years.

Methods: We conducted a retrospective analysis of surgical outcome in all neonatal patients who underwent cardiac surgery between January 2007 and July 2016 at Schneider Children's Medical Center of Israel.

Results: A total of 1003 neonates aged < 30 days underwent surgery for congenital heart defects at our center. Neonatal surgery accounted for 22.5% of all cardiac surgeries. Neonatal operative mortality was 7.3%, Operative mortality for individual lesions were: simple aortic coarctation (CoA) (198 patients, 2.5%), CoA with hypoplastic arch (24, 4%), CoA with ventricular septal defect (VSD) (84, 2.3%), transposition of the great arteries (TGA, simple and complex, 185, 6.3%), TGA with VSD (37, 0%), truncus arteriosus (26, 3.8%), interrupted aortic arch (25, 4%), Norwood Sano (71, 19.7%), neonatal tetralogy of Fallot (41, 0%), and shunt (131 patients, 12%).

Conclusions: Neonatal surgical capabilities have improved substantially over the last decades. Excellent results can be expected for lesions that can be repaired to create biventricular circulation. Improved results can be attributed in part to the evolution of surgical strategies and assistive technologies, but essential is the collaborative effort of surgeons, cardiologists, anesthesiologists, and intensive care specialists acting as a cohesive team whose performance far exceeds the sum of its individual members’ contributions.
