Item does not contain fulltext OBJECTIVES: This study examines the outcome and procedural outcomes of percutaneous stent angioplasty for aortic coarctation in patients with Turner syndrome (TS). BACKGROUND: TS occurs in 1 in 2,500 live-born females and is associated with aortic coarctation. METHODS: In this multicenter, retrospective cohort study, all patients with TS and a coarctation of the aorta, treated with percutaneous stent implantation were included. The procedural strategies were dictated by local protocols. Adverse events at short- and long-term follow-up and qualitative parameters concerning the stent implantation were assessed. RESULTS: In the largest study to date of TS patients receiving aortic stents, a total of 19 patients from 10 centers were included. Twelve patients were treated for native and 7 for recurrent coarctation. Age at intervention was 16.9 (7-60) years (median; min-max). The coarctation diameter increased significantly from 8.0 mm (2-12) pre-intervention to 15.0 mm (10-19) post-intervention (P < 0.001). Three (15.8%) adverse events occurred within 30 days of the procedure, including two dissections despite the use of covered stents, one resulting in death. At long-term follow-up (6.5 years, min-max: 1-16), two additional deaths occurred not known to be stent-related. CONCLUSIONS: Though percutaneous treatment of aortic coarctation in TS patients is effective, it is associated with serious morbidity and mortality. These risks suggest that alternative treatment options should be carefully weighed against percutaneous stenting strategies. (c) 2016 Wiley Periodicals, Inc.

BackgroundPulmonary artery (PA) aneurysms are rare and their related complications like dissection or rupture have been so far reported in a few reports, and a systematic description of the disease is lacking. To identify patients with PA aneurysm, at high-risk for complications, is critical. We performed a systematic review of the literature to determine characteristics that could identify high-risk patients. MethodA systematic search strategy was established and executed in Pubmed, Embase, Cochrane Central Register of Controlled Trials and Google scholar. Case reports were included if a minimal set of data were described. ResultsAfter executing the search strategy and exclusion of non-relevant or duplicate articles, 38 original articles, reviews and 169 case reports could be included. Articles were classified in high and low-pressure PA aneurysms and subdivided in six groups on basis of the causative mechanisms. PA dilatation was most common in association with pulmonary hypertension, but only one dissection was reported in 6 original articles containing 153 patients. Analysis of the case reports suggests that predictors of high-risk patients are: pulmonary hypertension in congenital heart disease, fast PA diameter growth (>2 mm/year), tissue weakness due to infection and possibly pregnancy especially in combination. Except for 2 cases, PA dissection did not occur, when the PA diameter was
