This controlled clinical study investigates arterial blood pressure and vascular remodling before and 4 weeks after catheter interventional treatment of re-stenosis of the aortic isthmus (Recoarctatio Aortae).
Patients with treated aortic isthmus stenosis during their first year of life often develop a Recoarctatio Aortae (re-stenosis of the aortic isthmus) in the long term followed by arterial hypertension. The Recoarctatio Aortae can be treated during a cather intervention by balloon dilatation or stent implantation. Patients with arterial hypertension often develop vascular remodeling with increased central systolic blood pressure and increased pulse pressure. Vascular remodling predics cardiovascular events and increases mortality. Vascular remodeling can be assessed non-invasively by using scanning laser doppler flowmetry (SLDF)), pulse wave analysis and measurement of flow-dependent vasodilation. In this controlled clinical study we investigate arterial blood pressure and vascular remodling before and 4 weeks after catheter interventional treatment of Recoarctatio Aortae.
