Matrix-assisted laser desorption/ionization mass spectrometric imaging the spatial distribution of biodegradable vascular stents using a self-made semi-quantitative target plate.

J Pharm Biomed Anal 2022 Jun 11;219:114888. Epub 2022 Jun 11.

Instrumental Analysis Center, Shanghai Jiao Tong University, Shanghai 200240, China. Electronic address:

In recent years, the development and optimization of biodegradable coronary stents have become the research focus of many medical device manufacturers and scientific research institutions since they can be completely degraded and absorbed, and they restore vascular function. However, there is a lack of in situ quantification of these stents spatially in tissue in vivo. In this study, matrix-assisted laser desorption/ionization (MALDI) Fourier transform ion cyclotron resonance (FT ICR) and time-of-flight (TOF) mass spectrometric imaging (MSI) were used to analyze the time-dependent distributions of a biodegradable vascular scaffold, which consisted of copolymers of lactic acid and glycolic acid (PLGA) and its degradation products in cross-sections and longitudinal sections of blood vessels.

Giant coronary aneurysms in an infant: Dilemma of MIS-C.

Echocardiography 2022 Jun 25. Epub 2022 Jun 25.

Washington State University/Elson S. Floyd College of Medicine, Spokane, Washington, USA.

COVID-19 related multisystem inflammatory syndrome in children (MIS-C) can present with cardiovascular complications like shock, arrhythmias, pericardial effusion, and coronary artery dilatation. The majority of MIS-C associated coronary artery abnormalities are dilation or small aneurysms which are transient and resolve in a few weeks. We present here a case of a 3-month-old child who was noted to have giant aneurysms of her coronary arteries (LAD and RCA) 26 days after testing positive for COVID-19. Read More

Mitral annular calcification: The incremental diagnostic value of 3D transesophageal echocardiography.

Echocardiography 2022 Jun 24. Epub 2022 Jun 24.

Medical College of Georgia, Augusta University, Augusta, Georgia, USA.

Three-dimensional (3D) echocardiography is an important tool in the evaluation of mitral valve anatomy. We illustrate a case of a 67-year-old female who was admitted for non-ST-elevation myocardial infarction (NSTEMI) and underwent two-vessel coronary artery bypass grafting for surgical disease. Her two-dimensional (2D) echocardiographic images intraoperatively demonstrated a mass on the posterior mitral valve leaflet which created a diagnostic challenge; 3D transesophageal imaging was crucial in identifying the true nature of the pathology to be mitral annular calcification with supra-annular extension.

Identification of a circulating microRNAs biomarker panel for non-invasive diagnosis of coronary artery disease: case-control study.

BMC Cardiovasc Disord 2022 Jun 24;22(1):286. Epub 2022 Jun 24.

Medical Genetics Unit, Department of Histology and Cell Biology, Faculty of Medicine, Suez Canal University, Ismailia, 41522, Egypt.

Background: Circulating microRNAs (miRNAs) are considered a hot spot of research that can be employed for monitoring and/or diagnostic purposes in coronary artery disease (CAD). Since different disease features might be reflected on altered profiles or plasma miRNAs concentrations, a combination of miRNAs can provide more reliable non-invasive biomarkers for CAD.

Subjects And Methods: We investigated a panel of 14-miRNAs selected using bioinformatics databases and current literature searching for miRNAs involved in CAD using quantitative real-time PCR technique in 73 CAD patients compared to 73 controls followed by function and pathway enrichment analysis for the 14-miRNAs.

Utility of sirolimus coated balloons in the peripheral vasculature - a review of the current literature.

CVIR Endovasc 2022 Jun 24;5(1):29. Epub 2022 Jun 24.

Department of Vascular Surgery, Singapore General Hospital, Singapore, Singapore.

Sirolimus-coated balloons (SCB) have demonstrated much promise as an alternative drug eluting device to the existing paclitaxel coated balloon platforms for the treatment of peripheral arterial disease (PAD). They have been well tested pre-clinically and have demonstrated anti-restenotic effects as well as clinical safety in its use for treatment of coronary artery disease. The existing approved SCBs have thus far demonstrated good short-term patency (12-months) and did not exhibit any major adverse events or device related shortcomings in its use for treatment of PAD.

COVID-19-associated hepatic artery pseudoaneurysms.

Liver Int 2022 Jun 24. Epub 2022 Jun 24.

AP-HP, Hôpital Necker Enfants Malades, Service d'Imagerie Adulte, Paris, France.

Cases of coronary and pulmonary artery pseudoaneurysms secondary to COVID-19 have been reported in the literature and are supposed to be secondary to inflammatory and vasculitis processes linked to a viral multisystem inflammatory syndrome. Although the incidence of COVID-19-associated liver injury ranges from 14% to 53% in hospitalized patients [5], COVID-19-associated hepatic artery pseudoaneurysms have never been reported so far. We present the case of a patient whose follow-up CT after cryoablation of renal cell carcinoma revealed seven fusiform pseudoaneurysms of the two hepatic arteries secondary to COVID-19. Read More

Heparin-free distal radial artery approach to cardiac catheterisation and the small radial recurrent artery.

Br J Cardiol 2021 1;28(3):39. Epub 2021 Sep 1.

Fellow in Interventional Cardiology Department of Cardiology, St. George's University Hospitals NHS Foundation Trust, London, SW17 0QT.

Radial artery access has transformed cardiac catheterisation, allowing it to be performed in a daycase setting, saving both hospital beds, and nursing care costs. However, there are two common and seemingly diametrically opposite complications. These are radial artery occlusion and forearm haematoma; the former could be reduced by heparin, but at the expense of precipitating the latter. Read More

Fang Qin Goh

Br J Cardiol 2021 2;28(3):30. Epub 2021 Jun 2.

House Officer (Postgraduate Year 1) Department of Internal Medicine, Singapore General Hospital, Outram Road, Singapore 169608.

Exercise prevents and aids treatment of coronary heart disease, hypertension, heart failure, diabetes mellitus, obesity and depression, reduces cardiac events and improves survival. However, evidence suggests that the relationship between exercise and mortality may be curvilinear, with modest additional benefit at higher levels. Intensive exercise has also been associated with increased atrial fibrillation risk, although its clinical implications are not well understood. Read More
