Quadricuspid aortic valve: a rare cause of aortic regurgitation and stenosis

The Turkish Journal of Pediatrics, 2008
Quadricuspid aortic valve is a rare congenital condition that occurs not only as an isolated anomaly, but also with other cardiac defects. We describe a 10-year-old boy whose aortic stenosis was diagnosed during infancy.

Macrophage‐targeted cerium‐tannic acid metal‐polyphenol framework nanoenzyme promotes in situ heart valves regeneration through adaptive immunomodulation

BMEMat, EarlyView.
A novel nanoenzyme based on cerium ions‐tannic acid metal‐polyphenol framework (FCT) has been developed and loaded onto DHVs for targeting M1 macrophages to reduce their ROS level and reprogram macrophage phenotype, thereby eliminating inflammation, promoting endothelialization and adaptive matrix remodeling of scaffolds, offering a promising strategy ...

The normal ranges of cardiovascular parameters measured using the ultrasonic cardiac output monitor [PDF]

, 2017
The ultrasonic cardiac output monitor (USCOM) is a noninvasive transcutaneous continuous wave Doppler method for assessing hemodynamics. There are no published reference ranges for normal values in adults (aged 18– 60 years) for this device.

A Meta‐Analysis and Simplified Nomenclature for Diagonal Coronary Artery and Ramus Intermedius Across Adult and Pediatric Hearts

Clinical Anatomy, EarlyView.
ABSTRACT Anatomical descriptions of left‐sided oblique coronary branches remain inconsistent, hindering imaging interpretation and surgical planning. To quantify the prevalence, branching patterns and morphometry of the ramus intermedius (RI) and diagonal branches, and propose a unified nomenclature.

P7 TELOMERE LENGTH AND AORTIC VALVE CALCIFICATION

Artery Research, 2018
Background: Short telomere length (TL) is associated with atherosclerosis development. Aortic valve stenosis, an age-related disease characterized by narrowing of the aortic opening, is mainly caused by aortic valve calcification.

Adipocytes in Aortic Stenosis: Association With Clinical and Morphological Indices

Clinical Anatomy, EarlyView.
ABSTRACT Recently, great attention has been given to understanding the new pathogenetic mechanisms underlying aortic stenosis (AS). The study aims to understand the role of mature adipocytes in AS and their association with histologic, clinical, and echocardiographic data, an area previously overlooked in AS research.
