J Oleo Sci 2021 Oct 12. Epub 2021 Oct 12.

Department of Applied Biological Chemistry, Kindai University.

Women are more resistant than men to the development of vascular diseases. However, menopause is a factor leading to deterioration of female vascular integrity, and it is reported that the risk of vascular diseases such as atherosclerosis and abdominal aortic aneurysm is increased in postmenopausal women. Although it is suggested that perivascular adipose tissue (PVAT) is deeply involved in the increased risk of vascular disease development, the effect of menopause on PVAT integrity is unknown.

Outflow Through Aortic Side Branches Drives False Lumen Patency in Type B Aortic Dissection.

Front Cardiovasc Med 2021 13;8:710603. Epub 2021 Aug 13.

Department of Vascular- and Endovascular Surgery, Medical Faculty and University Hospital Düsseldorf, Heinrich-Heine-University Düsseldorf, Düsseldorf, Germany.

Thoracic endovascular aortic repair (TEVAR) for type B aortic dissection (TBAD) aims to induce false lumen (FL) thrombosis by sealing intimal tears between the true (TL) and the FL, and blocking the inflow into the FL. Incomplete thrombosis of the FL is correlated with poor clinical outcome. We hypothesize that the number of major and minor branches arising from the FL affects FL patency and may negatively influence TEVAR induced FL thrombosis. Read More

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

Front Cardiovasc Med 2021 9;8:711099. Epub 2021 Aug 9.

Institute for Biomedical Engineering, University and ETH Zürich, Zurich, Switzerland.

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 assessment. In this work we investigate the effect of jet origin and trajectory of mild aortic regurgitation on left ventricular hemodynamics in a porcine model. A pig model of mild aortic regurgitation/PVL was established by transcatheter piercing and dilating the non-coronary (NCC) or right coronary cusp (RCC) of the aortic valve close to the valve annulus.

Coronary embolism due to possible thrombosis of prosthetic aortic valve - the role of optical coherence tomography: case report.

Eur Heart J Case Rep 2021 Jul 30;5(7):ytab115. Epub 2021 Jul 30.

Department of Cardiology, Swiss Cardiovascular Center Bern, Bern University Hospital, Freiburgstrasse 18, 3010 Bern, Switzerland.

Background: Coronary embolism is an important non-atherosclerotic cause of acute myocardial infarction (AMI) that requires an individualized diagnostic and therapeutic approach. Although certain angiographic criteria exist that render an embolic origin likely, uncertainty remains. Optical coherence tomography (OCT) is a high-resolution intracoronary imaging technology that enables visualization of thrombus and the underlying coronary vessel wall, which may be helpful to distinguish between an atherosclerotic and non-atherosclerotic origin of AMI.
