Correlation of Cardiac Index Measured by the PRAM Method With NIRS and Lactate Levels in Pediatric Aortic Coarctation Surgery

This prospective observational study aims to evaluate the correlation between cardiac index measured by the MostCare™ system (Pressure Recording Analytical Method, PRAM) and cerebral/renal regional oxygen saturation measured by near-infrared spectroscopy (NIRS) and arterial lactate levels in neonates and infants (body weight 2.5-3.5 kg, age 0-3 months) undergoing surgical repair of aortic coarctation. Measurements will be recorded at four intraoperative time points: after anesthesia induction, before aortic cross-clamp, 3 minutes after cross-clamp release, and at end of surgery. No additional intervention beyond standard anesthesia and surgical care will be applied.

Minima Stent System Post- Approval Study (PAS)

This Post-Approval Study is a single arm, prospective, multi-center, open-label study of patients treated with the Renata Minima Stent System in the United States. The objective of the study is to continue the assessment of device performance and capture outcome data on use of the device in real-world use.

Electronic Archive of Patients With Diagnosis and Suspected Prenatal Diagnosis of Aortic Coarctation

The purpose of this prosective and retrospective observational study is to analyze the clinical and echocardiographic characteristics of infants with prenatal diagnosis of suspected aortic coarctation (CoAo) in order to identify clinical and instrumental elements that can predict the risk of developing aortic coarctation in the neonatal period so that we can identify patients who are at high risk and would therefore require intensive care and observation; compared with low-risk patients, for whom early discharge would be evaluable.

Aortic Stiffness by CMR in Aortic Coarctation

This study investigates the correlation between medium-term systemic blood pressure control and aortic stiffness index in adults following coarctation stenting, using cardiac magnetic resonance (CMR) imaging.
