Key result
Endovascular stent implantation and surgical repair in patients with aortic coarctation resulted in no significant differences in aortic elasticity, left ventricular function, or myocardial T1 times.
Why the study?
Patients after aortic coarctation repair show impaired aortic bioelasticity and altered left ventricular mechanics predisposing to diastolic dysfunction, prompting evaluation of these properties by CMR following endovascular stenting versus surgery.
Does the method of aortic coarctation repair (stenting vs. surgery) affect long-term aortic elasticity and left ventricular properties?
Cross-Sectional (n=50)
No

Absolute Event Rate: 5.4% vs 4.9%
p-value: p=0.64
Aortic elasticity and ventricular mechanics do not differ significantly between patients who underwent surgical versus stent repair for aortic coarctation, suggesting intrinsic aortic abnormalities may play a larger role than the repair approach.
No takes yet. Share an insight, caveat, or question.
No differences in elasticity or function favor either repair; leaves open long-term outcome comparisons in coarctation.
Pieper et al. (2019) conducted a cross-sectional in Isolated aortic coarctation (n=50). Endovascular stent implantation vs. Surgical repair was evaluated on Aortic root distensibility (10^-3 mmHg^-1) (95% CI -2.23 - 1.37, p=0.64). Endovascular stent implantation and surgical repair in patients with aortic coarctation resulted in no significant differences in aortic elasticity, left ventricular function, or myocardial T1 times.
