We report the case of a patient with severe malignant hypertrophic obstructive cardiomyopathy (HOCM) and calcified stenosis of the proximal and middle left anterior descending (LAD) coronary artery. We elected to treat his ischemic heart disease first. We performed angioplasty of the proximal and middle LAD, after rotative atherectomy, and implanted two bare metal stents. Thirty days later we treated his HOCM by alcohol septal ablation with catheterization of the first septal branch through the mesh of the bare metal stent implanted in the LAD. To our knowledge, this is the first documented report of such a procedure.

Covalent organic frameworks (COFs) have drawn great interest in electrochemical sensing. However, most are integrated as enrichment units or reaction carriers and are co-modified with metal nanomaterials. Few studies use the single pristine COFs as an electrochemical signal amplifier.

Electronic coupling between individual redox units in a molecular assembly dictates their charge transfer efficacy. Being a well-defined crystalline structure, the metal-organic framework (MOF) ensures proper positioning of redox-active moieties and provides a unique platform to unveil their charge transfer dynamics and quantification with structural relationships. Here, we demonstrate a novel redox-active MOF with near-infrared through-space intervalence charge transfer by introducing a mixed valence state inside redox-active thiazolothiazole-based ligands (DPTTZ) upon photo- or electrochemical reduction.

Arterial diseases (ADs) are a significant health problem, with high mortality and morbidity rates. Endovascular interventions, such as balloon angioplasty (BA), bare-metal stents (BMSs), drug-eluting stents (DESs) and drug-coated balloons (DCBs), have made significant progress in their treatments. However, the issue has not been fully resolved, with restenosis remaining a major concern.

The unique redox properties of nanoscale cerium dioxide determine its diverse application in biology and medicine as a regulator of oxidative metabolism. Lipid modifiers of the nanoparticle surface change their biochemical properties and bioavailability. Complexes with lipids can be formed upon contact of the nanoparticles with the membrane.

Objective: it was to evaluate the efficacy and safety of rapamycin-eluting stents at different doses in the treatment of coronary artery narrowing in miniature pigs.
Methods: a total of 20 miniature pigs were randomly assigned into four groups: S1 group (low-dose rapamycin-coated stent, 55 µg/mm), S2 group (medium-dose rapamycin-coated stent, 120 µg/mm), S3 group (high-dose rapamycin-coated stent, 415 µg/mm), and D0 group (bare metal stent). The stent size was 3.
