Comprehensive assessment of the aortic valve in critically ill patients for the non-cardiologist. Part II: Chronic aortic regurgitation of the native valve

Anaesthesiology Intensive Therapy, 2021
Inadequate diastolic closure of the aortic valve causes aortic regurgitation (AR). Diastolic regurgitation towards the left ventricle (LV) causes LV volume overload, resulting in eccentric LV remodelling.

Echocardiographic Findings in Small‐Breed Dogs With Myxomatous Mitral Valve Disease and the Severity of Mitral Regurgitation, Heart Size and Clinical Signs Myxomatous Mitral Valve Disease in Dogs

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Myxomatous mitral valve disease (MMVD) is the most common acquired cardiac disorder in small‐breed dogs and is characterized by progressive mitral regurgitation that can lead to cardiac enlargement and clinical signs of heart failure. Accurate assessment of structural and hemodynamic changes using two‐dimensional, M‐mode and Doppler echocardiography is

Impact of Left Atrial Volume on Clinical Outcome in Organic Mitral Regurgitation

Journal of the American College of Cardiology, 2010
The purpose of this paper was to assess the link between left atrial (LA) volume at diagnosis and outcome of patients with mitral regurgitation (MR).Left atrial enlargement is a consequence of organic MR, but its association with clinical outcome independently of MR severity is uncertain.We prospectively enrolled 492 patients (age 63 +/- 15 years, 60 ...

Pulmonary Blood Volume in Mitral Regurgitation in Cavalier King Charles Spaniels

Journal of Veterinary Internal Medicine, 2010
Abstract Background Pulmonary edema and venous congestion are well-recognized signs of congestive heart failure (CHF) in advanced canine chronic mitral regurgitation (MR). However, little is known about pulmonary blood volume (PBV), blood pulmonary transit time (PTT), and the regulation of ...

Septaly Oriented Mild Aortic Regurgitant Jets Negatively Influence Left Ventricular Blood Flow—Insights From 4D Flow MRI Animal Study

Frontiers in Cardiovascular Medicine, 2021
Objectives: Paravalvular leakage (PVL) and eccentric aortic regurgitation remain a major clinical concern in patients receiving transcatheter aortic valve replacement (TAVR), and regurgitant volume remains the main readout parameter in clinical ...

A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

Advanced Science, Volume 13, Issue 27, 13 May 2026.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...
