Multimodality Imaging of the Anatomy of the Aortic Root

Journal of Cardiovascular Development and Disease, 2021
The aortic root has long been considered an inert unidirectional conduit between the left ventricle and the ascending aorta. In the classical definition, the aortic valve leaflets (similar to what is perceived for the atrioventricular valves) have also ...

Aqueously Upcycled Lignin with Emergent Tribonegativity for Skin‐Integrated Triboelectronics

Advanced Materials, EarlyView.
Aqueously upcycled lignin is transformed into a printable ink that self‐assembles into a nanotextured surface during printing with the highest reported biopolymer‐based tribonegativity. The resulting skin‐integrated triboelectric sensor enables high‐fidelity cardiovascular monitoring and objective mental workload classification, demonstrating a ...

Full-root Aortic Valve Replacement by Stentless Aortic Xenografts in Patients with Small Aortic Roots [PDF]

Journal of Visualized Experiments, 2017
In patients with small aortic roots who need an aortic valve replacement with biological valve substitutes, the implantation of the stented pericardial valve might not meet the functional needs. The implantation of a too-small stented pericardial valve, leading to an effective orifice area indexed to a body surface area less than 0.85 cm2/m2, is ...

Transarterial coil embolization of an aortic root pseudoaneurym in a patient with Loeys-Dietz syndrome: a case report

CVIR Endovascular, 2020
Background Loeys-Dietz syndrome (LDS) is a rare autosomal-dominant connective tissue disorder characterized by arterial aneurysms and vascular friability. Surgical intervention for LDS patients carries significant morbidity and mortality.

Measurement of aortic root dimensions by transesophageal echocardiography in adult patients undergoing cardiac surgery

Annals of Cardiac Anaesthesia, 2020
Background: Normal aortic root dimensions were established from studies from Western countries. As the body size is significantly associated with the aortic root dimensions, Thai populations may have smaller aortic root diameters.
