Article Synopsis
- Subvalvular aortic stenosis (SAS) is a condition that can cause obstruction in the left ventricular outflow tract and may progress to aortic valve regurgitation; this study reviews 30 years of surgical repairs for SAS at a single center.
- A retrospective review was conducted on 103 patients (avg. age 5.5 years) who underwent surgery from 1985 to 2020, revealing a 10-year survival rate of 90.8%, with certain factors increasing mortality risk.
- The study found a significant reoperation rate for SAS, with 21.6% at 10 years, though the type of surgical approach (myectomy vs. membrane resection) did not affect
Background: Valve repair is the procedure of choice for congenital aortic valve disease. With increasing experience, the surgical armamentarium broadened from simple commissurotomy to more complex techniques. We report our 30-year experience with pediatric aortic valve repair.

Aims: We here aimed to investigate the success rates in performing ultrasound (US) guided central venous catheter insertion (CVC) in neonates and small infants undergoing cardiac surgery, and to evaluate the practicability and feasibility of thereby using a novel wireless US transducer (WUST).
Methods: Thirty neonates and small infants with a maximum body weight of 10 kg and need for CVC before cardiac surgery were included in this observational trial and were subdivided into two groups according to their weight: < 5 kg and ≥ 5 kg.
The HeartMate 3 is a ventricular assist device that supports the heart with a centrifugal continuous flow. It contains a fully levitated rotor to minimize hemolysis and was initially designed as an apical intrapericardial implant. It can be used as a bridge to a transplant, to recovery, or to destination therapy.

Methods: The primary outcome endpoint of this study was the change in copeptin concentration perioperatively in patients with congenital heart disease after surgery, with the use of a cardiopulmonary bypass.
