The Time-Dependent Role of Bisphosphonates on Atherosclerotic Plaque Calcification.

J Cardiovasc Dev Dis 2022 May 25;9(6). Epub 2022 May 25.

Department of Biomedical Engineering, Florida International University, Miami, FL 33174, USA.

Atherosclerotic plaque calcification directly contributes to the leading cause of morbidity and mortality by affecting plaque vulnerability and rupture risk. Small microcalcifications can increase plaque stress and promote rupture, whereas large calcifications can stabilize plaques. Drugs that target bone mineralization may lead to unintended consequences on ectopic plaque calcification and cardiovascular outcomes. Read More

Mechanisms and Drug Therapies of Bioprosthetic Heart Valve Calcification.

Front Pharmacol 2022 3;13:909801. Epub 2022 Jun 3.

Department of Cardiovascular Surgery, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.

Valve replacement is the main therapy for valvular heart disease, in which a diseased valve is replaced by mechanical heart valve (MHV) or bioprosthetic heart valve (BHV). Since the 2000s, BHV surpassed MHV as the leading option of prosthetic valve substitute because of its excellent hemocompatible and hemodynamic properties. However, BHV is apt to structural valve degeneration (SVD), resulting in limited durability. Read More

Shockwave lithotripsy for treatment of calcific renal artery stenosis after an inadequately expanded renal artery stent.

Future Cardiol 2022 Jun 9. Epub 2022 Jun 9.

Mercy One, Iowa Heart Center, Des Moines, IA 50314, USA.

Renal artery calcifications can be associated with insufficient stent expansion and in-stent restenosis. Intravascular lithotripsy (IVL) uses shockwaves to disrupt calcium and treat calcific renal in-stent restenosis. Herein, the authors present a case to treat resistant reno-vascular hypertension and in-stent restenosis of an inadequately expanded renal stent in a patient with severe calcific renal artery stenosis.

Coronary Artery Calcium Scoring: Current Status and Future Directions.

Radiographics 2022 Jun 3:210122. Epub 2022 Jun 3.

From the Department of Radiology (Amit Gupta, K.B., E.K., J.D.P., J.G., M.R., L.M.C., R.C.G.) and Harrington Heart & Vascular Institute (S.R.), University Hospitals Cleveland Medical Center/Case Western Reserve University School of Medicine, 11100 Euclid Ave, Cleveland, OH 44106; and Department of Medicine, Mercy Health-St. Elizabeth Youngstown Hospital, Youngstown, OH (Aekta Gupta).

Coronary artery calcium (CAC) scores obtained from CT scans have been shown to be prognostic in assessment of the risk for development of cardiovascular diseases, facilitating the prediction of outcome in asymptomatic individuals. Currently, several methods to calculate the CAC score exist, and each has its own set of advantages and disadvantages. Agatston CAC scoring is the most extensively used method. Read More

Importance of Non-Newtonian Computational Fluid Modeling on Severely Calcified Aortic Valve Geometries-Insights From Quasi-Steady State Simulations.

J Biomech Eng 2022 Nov;144(11)

Department of Biomedical Engineering, Florida International University, Miami, FL 33174.

The Newtonian model has commonly been used to represent the viscosity of blood in the aorta, despite blood itself being a non-Newtonian fluid. This is justified where shear rates tend to be large. However, we hypothesized that using the Newtonian model to predict the hemodynamics on the aortic valve, particularly in those with severe calcifications, is inaccurate owing to valve leaflet geometry irregularities inducing multiple regions of low shear rates, <100 s-1, where a Newtonian model is invalid.

Assessment of post-dilatation strategies for optimal stent expansion in calcified coronary lesions: Ex vivo analysis with optical coherence tomography.

Cardiovasc Revasc Med 2022 May 6. Epub 2022 May 6.

Interventional Cardiology Center, Heart and Vascular Institute, University of South Florida, Tampa, FL 33606, USA.

Introduction: Interventional cardiologists make adjustments in the presence of coronary calcifications known to limit stent expansion, but proper balloon sizing, plaque-modification approaches, and high-pressure regimens are not well established. Intravascular optical coherence tomography (IVOCT) provides high-resolution images of coronary tissues, including detailed imaging of calcifications, and accurate measurements of stent deployment, providing a means for detailed study of stent deployment.

Objective: Evaluate stent expansion in an ex vivo model of calcified coronary arteries as a function of balloon size and high-pressure, post-dilatation strategies. Read More

The Role of Multimodality Imaging for Percutaneous Coronary Intervention in Patients With Chronic Total Occlusions.

Front Cardiovasc Med 2022 2;9:823091. Epub 2022 May 2.

Centro Cardiologico Monzino, Istituto di Ricerca e Cura a Carattere Scientifico (IRCCS), Milan, Italy.

Background: Percutaneous coronary intervention (PCI) of Chronic total occlusions (CTOs) has been traditionally considered a challenging procedure, with a lower success rate and a higher incidence of complications compared to non-CTO-PCI. An accurate and comprehensive evaluation of potential candidates for CTO-PCI is of great importance. Indeed, assessment of myocardial viability, left ventricular function, individual risk profile and coronary lesion complexity as well as detection of inducible ischemia are key information that should be integrated for a shared treatment decision and interventional strategy planning.

Assessment of age, gender, and anxiety on ECG waveform morphology in a large population of domestic dogs.

Sci Rep 2022 05 5;12(1):7339. Epub 2022 May 5.

IDEXX Laboratories, Inc., Westbrook, ME, USA.

Cardiovascular diseases are major causes of death in the western world and this incidence increases in the elderly population. With aging, there are physiologic changes to the cardiac structure secondary to adipose tissue deposition, calcification of valve leaflets and changes in the structure of the heart including atrial remodeling. Such changes can make the myocardium more susceptible to stress leading to a higher prevalence of cardiovascular diseases in the aging population. Read More

Cardiac Calcifications: Phenotypes, Mechanisms, Clinical and Prognostic Implications.

Biology (Basel) 2022 Mar 9;11(3). Epub 2022 Mar 9.

Laboratory for Technologies of Advanced Therapies (LTTA), Department of Translational Medicine, University of Ferrara, Via Fossato di Mortara 64/B, 44121 Ferrara, Italy.

There is a growing interest in arterial and heart valve calcifications, as these contribute to cardiovascular outcome, and are leading predictors of cardiovascular and kidney diseases. Cardiovascular calcifications are often considered as one disease, but, in effect, they represent multifaced disorders, occurring in different milieus and biological phenotypes, following different pathways. Herein, we explore each different molecular process, its relative link with the specific clinical condition, and the current therapeutic approaches to counteract calcifications. Read More
