Objectives: The presence of a mechanical aortic valve has been a contraindication to the use of an arch branch aortic endograft due to the risk of damaging the valve, resulting in acute aortic regurgitation, or a trapped endograft.

Methods: We present a 67-year-old woman, with a background of Marfan's syndrome and a previous Bentall's procedure, who presented with a symptomatic enlarging aortic arch and descending thoracic aortic aneurysm, with a type 1A endoleak.

Results: Using an inner branch arch endograft (Cook Medical, Bloomington, Indiana), the nose cone of the delivery system was passed laterally through the semi-circular aperture of the mechanical aortic valve to facilitate deployment just distal to the coronary buttons.

Conclusions: With advancement of endovascular technology, techniques and experience, endovascular aortic arch repair in the presence of a mechanical aortic valve is feasible.

This study employed large eddy simulation (LES) with the wall-adapting local eddy-viscosity (WALE) model to investigate transitional flow characteristics in an idealized model of a healthy thoracic aorta. The OpenFOAM solver pimpleFoam was used to simulate blood flow as an incompressible Newtonian fluid, with the aortic walls treated as rigid boundaries. Simulations were conducted for 30 cardiac cycles and ensemble averaging was employed to ensure statistically reliable results.

Objective: Frailty has become an increasingly recognized perioperative risk stratification tool. While frailty has been strongly correlated with worsening surgical outcomes, the individual determinants of frailty have rarely been investigated in the setting of aortic disease. The aim of this study was to examine the determinants of an 11-factor modified frailty index (mFI-11) on mortality and postoperative complications in patients undergoing endovascular aortic aneurysm repair (EVAR).

: Enhanced recovery after surgery (ERAS) protocols aim to improve clinical outcomes, shorten hospital length of stay (LOS), and reduce costs through a multidisciplinary perioperative approach. Although introduced in colorectal surgery, they are less established in cardiac surgery, especially in combination with on-table extubation (OTE). This study evaluates the impact of a novel ERAS concept with OTE (RERACS) in elective aortic-valve-replacement and coronary bypass surgery.

Desmoid tumors are a rare entity, especially in the pediatric population. There are no reports of such a tumor in newborns. They are associated with high rates of morbidity and mortality, even though they are benign soft tissue tumors.

: In-hospital mortality associated with myocardial infarction complicated by cardiogenic shock (MI-CS) remains critically high. A particularly challenging form, mixed shock (MS), combines features of cardiogenic shock (CS) with distributive elements such as vasodilation and reduced vascular resistance. MS is associated with elevated mortality rates and presents unique diagnostic and therapeutic challenges.
