Analysis of Coronary Vessels in Cleared Embryonic Hearts. [PDF]
Whole mount visualization of the embryonic coronary plexus from which the capillary and arterial networks will form is rendered problematic using standard microscopy techniques, due to the scattering of imaging light by the thick heart tissue, as these vessels are localized deep within the walls of the developing heart.

Summary: Blood and lymphatic vessels surrounding the heart develop through orchestrated processes from cells of different origins. In particular, cells around the outflow tract which constitute a primordial transient vasculature, referred to as aortic ...

Deep learning segmentation of major vessels in X-ray coronary angiography
X-ray coronary angiography is a primary imaging technique for diagnosing coronary diseases. Although quantitative coronary angiography (QCA) provides morphological information of coronary arteries with objective quantitative measures, considerable ...

Microvascular dysfunction in the immediate aftermath of chronic total coronary occlusion recanalization [PDF]
Objectives The aim of this study was to compare microvascular resistance under both baseline and hyperemic conditions immediately after percutaneous coronary intervention (PCI) of a chronic total occlusion (CTO) with an unobstructed reference vessel in ...

Multi-vessel coronary disease and percutaneous coronary intervention [PDF]
The goal of percutaneous coronary intervention (PCI) is to provide a safe, effective, less invasive alternative to coronary artery bypass graft surgery (CABG). When introduced by Andreas Gruentzig 25 years ago, he envisioned the procedure to be a technique that would delay the need for CABG until severe multi-vessel coronary disease was present.

Interaction between anandamide and sphingosine-1-phosphate in mediating vasorelaxation in rat coronary artery [PDF]
<b>BACKGROUND AND PURPOSE</b> Anandamide and sphingosine-1-phosphate (S1P) both regulate vascular tone in a variety of vessels. This study aimed to examine the mechanisms involved in the regulation of coronary vascular tone by anandamide and ...

Evaluation of Motion Artifact Metrics for Coronary CT Angiography [PDF]
Purpose This study quantified the performance of coronary artery motion artifact metrics relative to human observer ratings. Motion artifact metrics have been used as part of motion correction and best‐phase selection algorithms for Coronary Computed ...

Synthetic Vasopressin and Oxytocin Analogs and Their Potential Use in Hemorrhagic, Traumatic and Septic Shock: A Personal Perspective [PDF]
As one of us has stated many years ago, “shock is a significant and sustained loss of effective circulating blood volume. It will eventuate in hypoperfusion of critical peripheral tissues, thus leading to a deficit in transcapillary exchange function in ...
