Aortic isthmus massive calcifications: an unusual case of secondary hypertension.

We present the case of a 63-year-old woman who was hospitalized five times in 4 months for episodes of heart failure, associated with a sustained hypertension despite a fivefold therapy. The pathophysiological mechanism of the hypertension was a secondary hyperaldosteronism linked to a renal hypoperfusion due to the narrowing of the thoracic aorta by a huge calcified plaque, mimicking an aortic coarctation.

Implantation of ascyrus medical dissection stent, our first-hand experience.

Background: Acute type A aortic dissection is associated with high perioperative morbidity and mortality. Ascyrus Medical Dissection Stent (Cryolife, Kennesaw, USA) is a novel uncovered hybrid stent graft developed to be used as an adjunct to standard surgical approach to promote true lumen expansion and enhance aortic remodeling.

Methods: From March 2021 to March 2022, four consecutive patients presented with acute Debakey type I aortic dissection and underwent emergent surgical repair with Tirone David procedure and implantation of Ascyrus Medical Dissection Stent.

Does extracorporeal life support influence outcome after surgical management of post infarct ventricular septal rupture? A monocenter retrospective study.

Background: Ventricular septal rupture (VSR) is an uncommon but life-threatening complication of acute myocardial infarction. Extra corporeal life support (ECLS) use in the preoperative setting allows hemodynamic stabilization for a delayed surgery. We aimed to assess the role of ECLS in the preoperative period of post infarction VSR surgery.

Bicolor K-edge spectral photon-counting CT imaging for the diagnosis of thoracic endoleaks: A dynamic phantom study.

Purpose: The purpose of this study was to investigate the feasibility of identifying and characterizing the three most common types of endoleaks within a thoracic aorta aneurysm model using bicolor K-edge imaging with a spectral photon-counting computing tomography (SPCCT) system in combination with a biphasic contrast agent injection.

Materials And Methods: Three types of thoracic endoleaks (type 1, 2 and 3) were created in a dynamic anthropomorphic thoracic aorta phantom. Protocol consisted in an injection of an iodinated contrast material followed 80 seconds after an injection of a gadolinium-based contrast agent (GBCA).
