Snake Envenomation Simulating ST Elevation Myocardial Infarction.

Envenomation syndromes following snakebites can include tissue reaction, coagulopathy, nephrotoxicity, and neurotoxicity. Cardiotoxicity is rare but usually presents with dysrhythmias. Myocardial infarction after envenomation has rarely been reported.

Myocardial Infarction Secondary to Left Internal Mammary Artery Graft Occlusion After Left Subclavian Bypass.

Cardiogenic shock is a severe, often fatal presentation of acute myocardial infarction. This report presents an unusual case of ST-segment elevation myocardial infarction with left internal mammary artery occlusion occurring after instrumentation of the left subclavian artery as part of planned repair of a complex aortic aneurysm.

Long-Term Efficacy and Safety of Everolimus-Eluting Bioresorbable Vascular Scaffolds Versus Everolimus-Eluting Metallic Stents: A Meta-Analysis of Randomized Trials.

Background: Data regarding the long-term efficacy and safety of everolimus-eluting bioresorbable vascular scaffolds (BVS) compared with everolimus-eluting stents are limited. This meta-analysis aimed to compare the long-term outcomes with both devices.

Methods And Results: Randomized trials reporting clinical outcomes beyond 1 year and comparing BVS with everolimus-eluting stents were included.

Predictors and clinical impact of pre-existing and acquired thrombocytopenia following transcatheter aortic valve replacement.

Background: Data are limited regarding transcatheter aortic valve replacement (TAVR)-related thrombocytopenia (TP). We sought to thoroughly characterize the presence, clinical impact, and severity of TP associated with TAVR.

Methods And Results: Data were collected from 90 patients who underwent TAVR using the Edwards SAPIEN valve (59 TF, 29 TA, 2 Tao).

The microfluidic multitrap nanophysiometer for hematologic cancer cell characterization reveals temporal sensitivity of the calcein-AM efflux assay.

Cytometric studies utilizing flow cytometry or multi-well culture plate fluorometry are often limited by a deficit in temporal resolution and a lack of single cell consideration. Unfortunately, many cellular processes, including signaling, motility, and molecular transport, occur transiently over relatively short periods of time and at different magnitudes between cells. Here we demonstrate the multitrap nanophysiometer (MTNP), a low-volume microfluidic platform housing an array of cell traps, as an effective tool that can be used to study individual unattached cells over time with precise control over the intercellular microenvironment.
