Evaluating the Feasibility of Bioresorbable Iron-Based Covered Stent: A Clinical Trial

A single-center, feasible clinical study to Evaluate the Treatment of Iron Bioresorbable Covered Scaffold System in patients with Coarctation of the Aorta Diseases

Target Organ Damage in Patients With Repaired Coarctation of Aorta and Exercise Induced Hypertension

The goal of this observational study is to obtain data on the effect of exercise induced hypertension on target organs in adult patients with repaired coarctation of the aorta. The main questions it aims to answer are: * patients with exercise induced hypertension have signs of hypertensive heart disease? * patients with exercise induced hypertension have increased arterial stiffness? * patients with exercise induced hypertension have signs of hypertensive renal damage? Participants will be invited for an outpatient appointment during which medical history and physical investigation will be performed. They will undergo cardiopulmonary exercise testing during which blood pressure will be measured regularly. Transthoracic echocardiography will also be performed as well as assessment of arterial stiffness by measuring pulse wave velocity. Renal function will be assessed by blood and urine analysis.

Growth Trial: Study of the Renata Minima Stent

The objective of the clinical investigation is to access clinical safety and effectiveness of the Minima Stent in neonates, infants, and young children requiring intervention for common congenital vascular stenosis (i.e., coarctation of the aorta and/or pulmonary artery stenosis) who are indicated for treatment.

The Arch Watch Study: An Integrated Evaluation of Hemodynamics in Infants With Suspected Coarctation of the Aorta

Unrecognized coarctation of the aorta (CoA) is a life-threatening component of congenital heart disease (CHD) in which narrowing of the aorta causes obstructed blood flow to the lower half of the body; it can occur in isolation or in combination with other defects. CoA is the type of CHD most likely to be missed by current newborn screening. An evolving coarctation (during closure of the ductus arteriosus) can be challenging to diagnose until often devastating end-organ injury manifests, even in the ICU setting. This study will evaluate currently used tools, such as four extremity blood pressures and pulse oximetry, and the investigators will test new tools - resonance Raman spectroscopy (RRS) and photoplethysmography analysis- to assess the adequacy of oxygen delivery in newborns who are at risk for aortic arch obstruction. The investigators hypothesize that combining an assessment of commonly used non-invasive monitoring tools, new components of these traditional tools, and RRS, will have improved sensitivity in detecting critical impairments to tissue oxygen delivery in newborns with suspected critical aortic arch obstruction.
