Management of patients with transcatheter implantable aortic valve

open access: yesKlinicist, 2023
Valvular heart disease remains one of the causes of cardiovascular morbidity and mortality worldwide. Aortic stenosis is the most common valvular pathology requiring cardiac surgery.

Cardiovascular Risk Factors and Hemodynamic Measures as Determinants of Increased Arterial Stiffness Following Surgical Aortic Valve Replacement

open access: yesFrontiers in Cardiovascular Medicine, 2021
Valvular and arterial function are tightly intertwined, both in terms of structural changes and hemodynamics. While proximal valvulo-vascular coupling contributes to the cardiovascular consequences of aortic stenosis, less is known on how peripheral ...

Layered Plaque in Organic Lesions in Patients With Coronary Artery Spasm

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Coronary artery spasm plays a vital role in the pathogenesis of coronary plaques. We sought to investigate the plaque characteristics of co‐existing organic lesions in patients with coronary artery spasm in comparison to those without coronary

Segmental Tissue Speckle Tracking Predicts the Stenosis Severity in Patients With Coronary Artery Disease

open access: yesFrontiers in Cardiovascular Medicine, 2022
ObjectiveTwo-dimensional speckle tracking echocardiography (2D-STE) has been used as a diagnostic tool for coronary artery disease (CAD). However, whether vessel supplied myocardial strain and strain rate (SR) predict the severity of coronary artery ...

Anatomic and Hemodynamic Plaque Characteristics for Subsequent Coronary Events

open access: yesFrontiers in Cardiovascular Medicine, 2022
ObjectivesWhile coronary computed tomography angiography (CCTA) enables the evaluation of anatomic and hemodynamic plaque characteristics of coronary artery disease (CAD), the clinical roles of these characteristics are not clear.

Concertina Phenomenon in the Left Anterior Descending Artery: An Unexpected Circumstance in an Unexpected Vessel

open access: yesJournal of Tehran University Heart Center, 2018
The concertina phenomenon is the occurrence of new and transient angiographic series of pseudolesions in a tortuous vessel induced mainly by a stiff guide wire.
