Running on empty: Factors underpinning impaired cardiac output reserve in heart failure with preserved ejection fraction

Experimental Physiology, EarlyView.
Abstract Heart failure with preserved ejection fraction (HFpEF) is frequently attributed etiologically to an underlying left ventricular (LV) diastolic dysfunction, although its pathophysiology is far more complex and can exhibit significant variations among patients. This review endeavours to systematically unravel the pathophysiological heterogeneity

Effect of Parametric Variation of Chordae Tendineae Structure on Simulated Atrioventricular Valve Closure [PDF]

arXiv
Many approaches have been used to model chordae tendineae geometries in finite element simulations of atrioventricular heart valves. Unfortunately, current "functional" chordae tendineae geometries lack fidelity that would be helpful when informing clinical decisions.

Effects of noradrenaline and phenylephrine on cerebral oxygen saturation during cardiopulmonary bypass in cardiac surgery

Experimental Physiology, EarlyView.
Abstract Cardiopulmonary bypass (CPB) in cardiac surgery is associated with a high risk of postoperative neurological complications. Perioperative use of vasopressors is common to counteract arterial hypotension in this setting. However, use of α‐agonist vasopressors has been associated with cerebral desaturations.

Advancing aortic stenosis assessment: validation of fluid-structure interaction models against 4D flow MRI data [PDF]

arXiv
Systematic in vivo validations of computational models of the aortic valve remain scarce, despite successful validation against in vitro data. Utilizing a combination of computed tomography and 4D flow magnetic resonance imaging data, we developed patient-specific fluid-structure interaction models of the aortic valve immersed in the aorta for five ...

Mitral stenosis due to rheumatic heart disease - A rare cause of massive hemoptysis

Respiratory Medicine Case Reports, 2018
Severe mitral valve stenosis caused by rheumatic heart disease presenting initially as massive hemoptysis has become a rare occurrence in contemporary western medicine. Massive hemoptysis can be due to multiple disease processes including airway diseases

Genetic testing and counseling for hypertrophic cardiomyopathy: An evidence‐based practice resource of the National Society of Genetic Counselors

Journal of Genetic Counseling, Volume 34, Issue 3, June 2025.
Abstract Hypertrophic cardiomyopathy (HCM) is a common hereditary condition affecting approximately 1 in 500 adults. It is characterized by marked clinical heterogeneity with individuals experiencing minimal to no symptoms, while others may have more severe outcomes including heart failure and sudden cardiac death.

Diagnostic value of combined heart and lung ultrasound in emergency department patients with dyspnea

Clinical Physiology and Functional Imaging, Volume 45, Issue 3, May 2025.
Abstract Background Acute dyspnea in emergency departments (ED) requires prompt and accurate diagnosis due to its high mortality and readmission rates. Conventional diagnostic methods are resource‐intensive and time‐consuming. This study aimed to evaluate the diagnostic accuracy and time to diagnosis of combined heart and lung ultrasound (HeaLus ...
