Study of the normal heart size in Northwest part of Iranian population: a cadaveric study [PDF]

Journal of Cardiovascular and Thoracic Research, 2016
Introduction: The heart is in a muscular organ in the middle mediastinum. According to our knowledge, there is no standard data about the anthropologic parameters of normal Iranian hearts. Hence, the aim of the present study was to investigate the normal

Biological niches within human calcified aortic valves. Towards understanding of the pathological biomineralization process [PDF]

, 2015
Despite recent advances, mineralization site, its microarchitecture, and composition in calcific heart valve remain poorly understood. A multiscale investigation, using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and ...

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

Non-vitamin K antagonist oral anticoagulants in atrial fibrillation accompanying mitral stenosis: the concept for a trial. [PDF]

, 2015
Patients at thromboembolic risk with non-valvular atrial fibrillation (AF) can now be managed either with a vitamin K antagonist (VKA) or with a fixed dose of a non-VKA oral anticoagulant (NOAC), while patients with valvular AF have been restricted to ...

Valvular Heart Disease and Its Association With Death in Advanced Heart Failure

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Valvular heart disease contributes to symptomatic heart failure, but its prevalence and prognostic significance in advanced heart failure is not well understood. Methods This retrospective population‐based cohort study included adult residents

Diagnosis of mitral insufficiency using impedance cardiography technique ICG

Journal of Electrical Bioimpedance, 2016
Impedance cardiography (ICG) is a non-invasive tool for assessing the hemodynamic parameters. It has been used for diagnosing several cardiovascular diseases, such as heart failure, cardio-myopathy, and valvular diseases. Particularly, the valvular heart

Improvement of Rheumatic Valvular Heart Disease in Patients Undergoing Prolonged Antibiotic Prophylaxis

Frontiers in Cardiovascular Medicine, 2021
Secondary prophylaxis of rheumatic heart diseases is efficient in reducing disease recurrence, heart damage, and cardiac impairment. We aimed to monitor the clinical evolution of a large Brazilian cohort of rheumatic patients under prolonged secondary ...
