The aim of our study was to evaluate the hemodynamic effects of endovascular treatment for CoA by using invasive aortic catheterization.<\/jats:p><jats:p>\n          Methods\u2003All patients with CoA who underwent treatment by aortic stent implantation between September 1, 2003, and February 1, 2019, at the \u201cOnassis Cardiac Surgery Center,\u201d in Athens, Greece, were evaluated. Patients were treated with either bare (uncovered) Cheatham-Platinum (bCP) or covered Cheatham-Platinum (cCP) stent implantations. Invasive aortic pressure measurements were recorded before and after the endovascular intervention.<\/jats:p><jats:p>\n          Results\u2003A total of 48, eight zig CP stents, comprising 24 bCP and 24 cCP stents were implanted in 47 patients. The mean aortic diameter (mm) at the CoA lesion increased from 9.7\u2009\u00b1\u20093.3 to 19.2\u2009\u00b1\u20092.9\u2009mm (p &lt;0.01) after the endovascular procedure. The invasive mean blood pressure (BP; mm Hg) from catheterization in the descending aorta increased (before\u2009=\u2009114.2\u2009\u00b1\u200912.8 vs. after\u2009=\u2009135.5\u2009\u00b1\u200928.1; p &lt;0.01), while the invasive mean BP (mm Hg) from catheterization in the ascending aorta was decreased (before\u2009=\u2009156.8\u2009\u00b1\u200925.0 vs. after\u2009=\u2009138.4\u2009\u00b1\u200927.5; p &lt;0.01) after the intervention. The mean aortic BP gradient decreased in both types of stents after intervention (BP gradient among patients with cCP stents = 30.9 +\/\u2212 23.6 mmHg and BP gradient among patients with bCP stents = 38.0 +\/\u221223.1 mmHg). However, there was no statistically significant difference between the two types of stents; p\u2009=\u20090.36.<\/jats:p><jats:p>\n          Conclusions\u2003Invasive aortic catheterization provided evidence that endovascular stenting with either bare or covered stents is efficient in treating patients with
