A deep learning approach to using wearable seismocardiography (SCG) for diagnosing aortic valve stenosis and predicting aortic hemodynamics obtained by 4D flow MRI [PDF]

open access: yesarXiv, 2023
In this paper, we explored the use of deep learning for the prediction of aortic flow metrics obtained using 4D flow MRI using wearable seismocardiography (SCG) devices. 4D flow MRI provides a comprehensive assessment of cardiovascular hemodynamics, but it is costly and time-consuming.

Interactive-Automatic Segmentation and Modelling of the Mitral Valve [PDF]

open access: yes, 2019
Mitral valve regurgitation is the most common valvular disease, affecting 10% of the population over 75 years old. Left untreated, patients with mitral valve regurgitation can suffer declining cardiac health until cardiac failure and death. Mitral valve repair is generally preferred over valve replacement. However, there is a direct correlation between

Ease of sutureless aortic valve replacement in a patient with unexpected ochronosis: a case report

open access: yesJournal of Cardiothoracic Surgery
Background Alkaptonuria is a rare congenital metabolic disorder characterized by homogentisic acid accumulation in body cartilage and connective tissues due to a deficient homogentisic acid dioxygenase enzyme.

Reduced-order modeling of left ventricular flow subject to aortic valve regurgitation [PDF]

open access: yesPhysics of Fluids, 31(3), 031901 (2019), 2019
The present focus of heart flow studies is largely based on flow within the left ventricle and how this flow changes when subject to disease. However, despite recent advancements, a simple tractable model of even healthy left ventricular flow has not been produced and made available.

Bicuspid Aortic Valve: Morphology, Clinic, Diagnosis, Complications

open access: yesРациональная фармакотерапия в кардиологии, 2021
Bicuspid aortic valve refers to common (0.5-2% of the population) congenital heart defects that are asymptomatic throughout life, with valve dysfunction and/or aortopathy (pathia- from Greek pathos disease), manifested by expansion, aneurysm or ...

Fluid dynamics of heart valves during atrial fibrillation: a lumped parameter-based approach [PDF]

open access: yes, 2015
Atrial fibrillation (AF) consequences on the heart valve dynamics are usually studied along with a valvular disfunction or disease, since in medical monitoring the two pathologies are often concomitant. Aim of the present work is to study, through a stochastic lumped-parameter approach, the basic fluid dynamics variations of heart valves, when only ...

Valvulopathies and Genetics: Where are We?

open access: yesReviews in Cardiovascular Medicine
Valvulopathies are among the most common cardiovascular diseases, significantly increasing morbidity and mortality. While many valvular heart diseases are acquired later in life, an important genetic component has been described, particularly in mitral ...

Almanac 2011: Valvular heart disease. The national society journals present selected research that has driven recent advances in clinical cardiology

open access: yesThe Egyptian Heart Journal, 2012
With an ageing population and improved diagnostic modalities, the number of patients with valvular heart disease is dramatically increasing. We are faced with more complex decisions in patients with advanced age and increasing comorbidities.

Antithrombotic Treatment After Surgical and Transcatheter Heart Valve Repair and Replacement

open access: yesFrontiers in Cardiovascular Medicine, 2021
New antithrombotic drugs have been developed, new valve types have been designed and minimally invasive transcatheter techniques have emerged, making the choice of antithrombotic therapy after surgical or transcatheter heart valve repair and replacement ...

Molecular Analysis of Oral Bacteria in Heart Valve of Patients With Cardiovascular Disease by Real-Time Polymerase Chain Reaction

open access: yesMedicine, 2015
Structural deficiencies and functional abnormalities of heart valves represent an important cause of cardiovascular morbidity and mortality, and a number of diseases, such as aortic stenosis, have been recently associated with infectious agents.
