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.

Coarctation of the aorta (COA) is a common form of congenital heart disease with an incidence of 1 in 3000-4000 live births, characterized by the narrowing of the aorta, which leads to significant hemodynamic changes, including increased afterload, hypertension, and ultimately, adverse cardiovascular outcomes. Despite successful surgical or interventional treatment to correct the anatomical defect, patients with coarctation of the aorta often continue to experience elevated systemic blood pressure and increased aortic stiffness, which are important predictors of long-term cardiovascular morbidity and mortality. Stenting has emerged as a preferred interventional strategy for treating aortic coarctation in adults due to its less invasive nature and immediate efficacy in relieving aortic obstruction. However, the medium-term impact of stenting on aortic stiffness remains underexplored. Understanding these changes is crucial for optimizing long-term management strategies and improving patient outcomes. Cardiac magnetic resonance (CMR) imaging offers a non-invasive and highly accurate method for assessing aortic stiffness, providing detailed insights into the structural and functional properties of the aorta. The aortic stiffness index, derived from CMR measurements, serves as a valuable biomarker for vascular health and has been linked to systemic blood pressure levels. This study aims to investigate the correlation between medium-term systemic blood pressure control and aortic stiffness index in adults following coarctation stenting. By assessing patients pre- and post-stenting using CMR, we seek to determine whether improvements in aortic stiffness correspond with better blood pressure management over time. Our findings could provide valuable insights into the benefits of stenting beyond immediate hemodynamic relief, highlighting its role in the long-term cardiovascular health of patients with aortic coarctation.
