- BACKGROUND Coarctation of the aorta (CoA), a congenital narrowing of the proximal descending thoracic aorta, is a relatively common form of congenital heart disease. Untreated significant CoA has a major impact on morbidity and mortality. In the past 3 decades, transcatheter intervention (TCI) for CoA has evolved as an alternative to surgery.OBJECTIVES The authors report on all TCIs for CoA performed from 2000 to 2016 in 4 countries covering 25 million inhabitants, with a mean follow-up duration of 6.9 years.METHODS During the study period, 683 interventions were performed on 542 patients.RESULTS The procedural success rate was 88%, with 9% considered partly successful. Complications at the intervention site occurred in 3.5% of interventions and at the access site in 3.5%. There was no in-hospital mortality. During follow-up, TCI for CoA reduced the presence of hypertension significantly from 73% to 34%, but despite this, many patients remained hypertensive and in need of continuous antihypertensive treatment. Moreover, 8% to 9% of patients needed aortic and/or aortic valve surgery during follow-up.CONCLUSIONS TCI for CoA can be performed with a low risk for complications. Lifetime follow-up after TCI for CoA seems warranted. (J Am Coll Cardiol Intv 2023;16:444-453) & COPY; 2023 by the American College of Cardiology Foundation.

- Involvement of gut immune system has been implicated in the pathogenesis of type 1 diabetes. However, few studies have been performed on the gut mucosa from patients with type 1 diabetes. Thus, we characterized the stage of immune activation in jejunal biopsy samples from 31 children with type 1 diabetes by immunohistochemistry, in situ hybridization, and RT-PCR. We found enhanced expressions of HLA-DR, HLA-DP, and intercellular adhesion molecule-1 by immunohistochemistry even on structurally normal intestine of patients with type 1 diabetes and no signs of celiac disease. In addition, the densities of IL-1a- and IL-4-positive cells detected by immunohistochemistry and IL-4 mRNA-expressing cells evaluated by in situ hybridization were increased in the lamina propria in patients with type 1 diabetes and normal mucosa. Instead, the densities of IL-2, ?-interferon (IFN-?), and tumor necrosis factor a-positive cells, the density of IFN-? mRNA positive cells, and the amounts of IFN-? mRNA detected by RT-PCR correlated with the degree of celiac disease in patients with type 1 diabetes. Our study supports the hypothesis that a link exists between the gut immune system and type 1 diabetes.
