Age‐related changes in the coronary microcirculation influencing the diagnostic performance of invasive pressure‐based indices and long‐term patient prognosis

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1195-1205, December 1, 2022., 2022
Abstract Objectives Investigate age‐related changes in coronary microvascular function, its effect on hyperemic and non‐hyperemic indices of stenosis relevance, and its prognostic implications. Background Evidence assessing the effect of age on fractional flow reserve (FFR), resting mean distal intracoronary pressure/mean aortic pressure (Pd/Pa), and ...

An Improved Approach for Cardiac MRI Segmentation based on 3D UNet Combined with Papillary Muscle Exclusion [PDF]

arXiv
Left ventricular ejection fraction (LVEF) is the most important clinical parameter of cardiovascular function. The accuracy in estimating this parameter is highly dependent upon the precise segmentation of the left ventricle (LV) structure at the end diastole and systole phases.

Wearable Hyperspectral Photoplethysmography Allows Continuous Monitoring of Exercise‐Induced Hypertension

Advanced Science, EarlyView.
A wearable hyperspectral photoplethysmography (HS‐PPG) is reported for continuous blood pressure (BP) monitoring. The HS‐PPG module integrates an ultrathin double‐folded solid immersion grating microspectrometer (DFSIG‐µSPEC), achieving a high spectral resolution of 3.4 nm.

Transcatheter valve repair of tricuspid regurgitation with the PASCAL system: TriCLASP study 30‐day results

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1291-1299, December 1, 2022., 2022
Abstract Background Severe tricuspid regurgitation (TR) is independently associated with increased morbidity and mortality. Percutaneous transcatheter approaches may offer an alternative for patients not amenable to surgery. Methods TriCLASP is a prospective, single‐arm, multicenter European post‐market clinical follow‐up study (NCT04614402) to ...

Diastolic function in hypertrophic cardiomyopathy: effects of propranolol and verapamil on diastolic stiffness [PDF]

, 2017
In patients with hypertrophic cardiomyopathy (HCM), impaired left ventricular (LV) relaxation and diastolic filling have been reported. Therefore, we determined LV diastolic stiffness in nine patients with HCM before and 10 to 15 min after 0·15 mg/kg ...

Flavonifractor Plautii or Its Metabolite Desaminotyrosine as Prophylactic Agents for Alleviating Myocardial Ischemia/Reperfusion Injury

Advanced Science, EarlyView.
The gut microbiome is a potential target for treating cardiovascular disease. It is found that prophylactic administration of Flavonifractor plautii or its metabolite desaminotyrosine (DAT) exerts pleiotropic cardioprotective effects via promoting cardiomyocyte survival and attenuating cardiac inflammation against myocardial ischemia/reperfusion (I/R ...

Fish Swim Bladder‐Derived ECM Hydrogels Effectively Treat Myocardial Ischemic Injury through Immunomodulation and Angiogenesis

Advanced Science, EarlyView.
A unique hydrogel based on extracellular matrix from fish swim bladder, which is suitable for transcatheter delivery and possesses remarkable reparative capabilities for treating heart failure, is developed. It emerges as a multi‐effect factor profoundly influencing inflammation regulation, angiogenesis, and myocardial metabolism.

Deep Neural Networks for ECG-free Cardiac Phase and End-Diastolic Frame Detection on Coronary Angiographies [PDF]

arXiv, 2018
Invasive coronary angiography (ICA) is the gold standard in Coronary Artery Disease (CAD) imaging. Detection of the end-diastolic frame (EDF) and, in general, cardiac phase detection on each temporal frame of a coronary angiography acquisition is of significant importance for the anatomical and non-invasive functional assessment of CAD.
