Adjunctive Techniques for Repair of Ischaemic Mitral Regurgitation

Cardiac Failure Review, 2021
Ischaemic mitral regurgitation is a complex process with debate in the literature as to the optimal treatment pathway. Multiple therapies are available to alleviate mitral regurgitation including medical management, transcatheter edge-to-edge repair ...

Soft Beats: A Dielectric Elastomer‐Based Ventricular Assist Device for Next‐Gen Heart Failure Management

Advanced Engineering Materials, EarlyView.
The dielectric elastomer‐based electropneumatic device (DE‐EPD) is a vacuum‐assisted ventricular assist device (VAD) that delivers high performance (85 mmHg, 6.8 L min−1) with low power consumption. Unlike traditional motor‐driven VADs, it is lightweight, quiet, energy‐efficient, and provides pulsatile flow. Validated in a simulated circulation system,

Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

Advanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...

Changes in hemodynamics of pulmonary artery using Flowire in a canine model of acute pulmonary thromboembolism

Animal Models and Experimental Medicine, EarlyView.
This study investigated changes in pulmonary artery hemodynamics using a Flowire catheter and evaluated the accuracy of Doppler echocardiography in dogs with acute pulmonary thromboembolism (PTE). Ten healthy beagles were anesthetized, and acute pulmonary hypertension (PH) was induced by injecting 300‐μm dextran microspheres.

Mitral Anterior Leaflet Perforation Due to Jet Flow in Aortic Valve Insufficiency

Kardiyovasküler Tıp E Dergisi/E Journal of Cardiovascular Medicine
Mitral valve disease is one of the most common pathologies of heart valve diseases. Mitral regurgitation may develop due to pathologies in the valve apparatus (primary regurgitation) or due to pathologies related to the atrium and/or ventricle (secondary

Segmentation of jet area to quantity the severity of mitral regurgitation by color Doppler echocardiography

International Journal of Noncommunicable Diseases, 2018
Mitral regurgitation (MR) is a disorder of mitral valve and it is one of the most common causes of cardiovascular morbidity and mortality. Mitral valve allows blood to flow from left atrium, to the left ventricle and Mitral Valve regurgitation results in

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

The Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.
