Aortic Valve Surgery in Nonelderly Patients: Insights Gained From AVIATOR.

, 2021
Aortic valve surgery in non-elderly patients represents a very challenging patient population. The younger the patient is at the point of aortic valve intervention, the longer their anticipated life expectancy will be, with longer exposure to valve ...

Descriptive, stratigraphic, and morpho‐functional study of the myocardium and myocardial bridges in domestic pig hearts

The Anatomical Record, EarlyView.
Abstract The heart is the central organ of the cardiovascular system. The myocardium is composed of a three‐dimensional network of fibers arranged in clockwise and counterclockwise helices, which are essential for proper cardiac contraction. This study aimed to describe the stratigraphic and morpho‐functional pattern of the porcine myocardium to ...

Myxomatous degeneration of aortic valve causing severe aortic regurgitation. A rare case report

SAGE Open Medical Case Reports
Myxomatous degeneration of a valve is a non-inflammatory degenerative process due to the disruption of the fibrous layer of the valve with mucopolysaccharide accumulation. It is mostly seen in the mitral valve but involvement in only aortic valve is rare.

Emergency treatment of acute decompensated critical aortic stenosis with transcatheter aortic valve implantation

, 2020
Transcatheter aortic valve implantation (TAVI) is relatively contraindicated in the bicuspid aortic valve, and to our knowledge has not been tried where the true native annulus is of a size far in excess of current device capabilities.

Morphological variation of the conus arteriosus in Chondrichthyes: Implications for ecology and evolution

The Anatomical Record, EarlyView.
Abstract Cartilaginous fish have diverse morphological traits that are essential for understanding their evolutionary history and ecological adaptations. However, the conus arteriosus and its valves, key components of the heart and blood circulation, have been underexplored in phylogenetic and ecomorphological contexts.

The effect of statins therapy in aortic stenosis: Meta-analysis comparison data of RCTs and observationals

Data in Brief, 2016
Aortic stenosis has been shown to share the same risk factors as atherosclerosis which suggested a potential benefit from statins therapy. Fourteen studies which provided the effect of statins treatment on aortic stenosis (AS) were meta-analyzed ...

Anatomical and histological characterization of the heart of the scarlet ibis (Eudocimus ruber)

The Anatomical Record, EarlyView.
The graphical abstract illustrates the scarlet ibis (Eudocimus ruber) and two views of its heart (ventral and dorsal), highlighting its external morphology. The study also employed complementary approaches, including morphometric analysis, radiography, histological examination, and scanning electron microscopy, to provide a comprehensive ...

Hemangioma of the Atherosclerotic Changed Aortic Valve

Case Reports in Cardiology, 2019
The incidence of heart valve hemangioma is very low and is mostly observed in the mitral and tricuspid valve. In 2006, two cases of aortic valve hemangioma were reported for the first time, including one with calcifying aortic valve stenosis.
