Patients with Eisenmenger syndrome had impaired longitudinal RV and LV strain, but present a relatively important apical deformation. RV and LV remodelling, as assessed by speckle-tracking imaging, differ between patients with pre- and post-tricuspid shunt.

Native coarctation of the aorta (CoA) and recoarctation (reCoA) after initial surgical repair are frequently associated with hypertension (HT). Most CoA cases are amenable to transcatheter balloon angioplasty with stent implantation; however, the impact of stenting on arterial blood pressure (BP) is variable. We carried out a retrospective study to identify the predictive factors for residual HT despite optimal endovascular treatment. Patients who had undergone stent implantation for native CoA or reCoA with a pressure gradient of >20 mm Hg between the upper and lower limbs, between 2007 and 2015, were included. The geometry and level of hypoplasia of the aortic arch were determined by non‐invasive imaging, and BP measurements were performed pre‐ and post‐procedure. Thirty consecutive patients (median age: 18.5 years; 76.7% male) were included. Twenty‐three patients had HT before the procedure and 14 (46.7%) had post‐procedural HT despite optimal endovascular treatment. Residual HT post‐stenting was associated with longer stent length and gothic arch geometry. Age and body mass index (BMI) were also associated with residual HT. The pathologic association of abnormal arch geometry and aortic stent placement may lead to a loss of aortic compliance that is further increased by high BMI and older age. Determination of a patient's aortic arch anatomy and clinical profile can assist in defining those at high risk of residual HT despite optimized isthmic stent implantation.
