Models and Techniques to Study Aortic Valve Calcification , and . An Overview.

Front Pharmacol 2022 2;13:835825. Epub 2022 Jun 2.

Department of Molecular Medicine, Institute of Basic Medical Sciences, University of Oslo, Oslo, Norway.

Aortic valve stenosis secondary to aortic valve calcification is the most common valve disease in the Western world. Calcification is a result of pathological proliferation and osteogenic differentiation of resident valve interstitial cells. To develop non-surgical treatments, the molecular and cellular mechanisms of pathological calcification must be revealed. Read More

Multiparametric MRI identifies subtle adaptations for demarcation of disease transition in murine aortic valve stenosis.

Basic Res Cardiol 2022 05 29;117(1):29. Epub 2022 May 29.

Cardiovascular Research Laboratory, Division of Cardiology, Pulmonary Diseases and Vascular Medicine, Medical Faculty, Heinrich Heine University, Düsseldorf, Germany.

Aortic valve stenosis (AS) is the most frequent valve disease with relevant prognostic impact. Experimental model systems for AS are scarce and comprehensive imaging techniques to simultaneously quantify function and morphology in disease progression are lacking. Therefore, we refined an acute murine AS model to closely mimic human disease characteristics and developed a high-resolution magnetic resonance imaging (MRI) approach for simultaneous in-depth analysis of valvular, myocardial as well as aortic morphology/pathophysiology to identify early changes in tissue texture and critical transition points in the adaptive process to AS.

Severe Aortic Valve Stenosis and Pulmonary Hypertension: A Systematic Review of Non-Invasive Ways of Risk Stratification, Especially in Patients Undergoing Transcatheter Aortic Valve Replacement.

J Pers Med 2022 Apr 8;12(4). Epub 2022 Apr 8.

Department of Internal Medicine II, Division of Cardiology, Paracelsus Medical University of Salzburg, 5020 Salzburg, Austria.

Patients with severe aortic valve stenosis and concomitant pulmonary hypertension show a significantly reduced survival prognosis. Right heart catheterization as a preoperative diagnostic tool to determine pulmonary hypertension has been largely abandoned in recent years in favor of echocardiographic criteria. Clinically, determination of echocardiographically estimated systolic pulmonary artery pressure falls far short of invasive right heart catheterization data in terms of accuracy. Read More

Paravalvular Leak.

Methodist Debakey Cardiovasc J 2022 1;18(1):7-9. Epub 2022 Apr 1.

Houston Methodist DeBakey Heart & Vascular Center, Houston, Texas, US.

Despite improvements and advancements in surgical technique, paravalvular leaks (PVL) continue to present a challenge when caring for patients with prosthetic valve disease. Paravalvular leaks result from dehiscence of the surgical ring from the mitral annulus. Some theories suggest that uneven distribution of collagen fibers in the mitral annulus leaves the posterior mitral annulus without a well-formed fibrous structure, which may predispose it to recurrent mechanical injury that leads to PVL.

Transcatheter closure of tubular patent ductus arteriosus using muscular ventricular septal defect devices in infants and small children with congestive heart failure.

Arch Cardiovasc Dis 2022 Mar 24;115(3):134-141. Epub 2022 Feb 24.

Paediatric Cardiology Services, Royal Brompton Hospital and Harefield NHS Foundation Trust, London SW3 6NP, UK; National Heart and Lung Institute, Guy Scadding Building, London SW3 6LY, UK. Electronic address:

Background: Transcatheter closure of a patent ductus arteriosus in children is widely performed to reduce symptoms and decrease the risk of endocarditis. Most arterial ducts are closed successfully with dedicated devices. However, in a tubular or "type C" patent ductus arteriosus with congestive heart failure, the occlusion is more challenging with these devices, with a higher risk of complications, such as aortic or left pulmonary stenosis and device embolization.

Physical activity and exercise recommendations for patients with valvular heart disease.

Heart 2022 Mar 2. Epub 2022 Mar 2.

Cardiovascular Clinical Academic Group, St George's University of London, London, UK

There is a paucity of studies looking at the natural history of valvular heart disease (VHD) in exercising individuals, and exercise recommendations are largely based on expert consensus. All individuals with VHD should be encouraged to avoid sedentary behaviour by engaging in at least 150 min of physical activity every week, including strength training. There are generally no exercise restrictions to individuals with mild VHD. Read More

Timing of pulmonary valve replacement: can we use the same volumetric thresholds in repaired tetralogy of Fallot and pulmonary stenosis?

Cardiol Young 2022 Mar 2:1-6. Epub 2022 Mar 2.

Schneeweiss Adult Congenital Heart Center, Columbia University Irving Medical Center, New York, NY, USA.

The timing of pulmonary valve replacement in patients with pulmonary regurgitation following treatment of pulmonary stenosis is undefined. Although cardiac magnetic resonance-based right ventricular volumes in tetralogy of Fallot patients have been used as a guide in pulmonary stenosis patients, anatomic differences between tetralogy of Fallot and pulmonary stenosis patients complicate their application to pulmonary stenosis patients and could result in late referral for pulmonary valve replacement. We sought to determine if pulmonary stenosis patients referred for pulmonary valve replacement were at greater risk for morbidity or need for tricuspid valve intervention at the time of pulmonary valve replacement.
