Relationship between hypoplastic right coronary artery and coronary artery anomalies [PDF]

open access: yesEuropean Heart Journal, 2013
The frequency of hypoplastic right coronary artery (HRCA) and its contribution to coronary artery anomalies (CAAs) has not been thoroughly studied. Here we aimed to investigate whether a casual relationship exists between the presence of HRCA and CAAs.We retrospectively reviewed coronary angiography records of 7500 patients.

Single Coronary Artery with Anomalous Origin of the Right Coronary Artery from the Distal Portion of Left Circumflex Artery: A Very Rare Case [PDF]

open access: yes, 2012
Congenital anomalies of coronary arteries, albeit rare, may be significant contributors to angina pectoris, hemodynamic abnormalities, and sudden cardiac death. A 47-year-old man referred to us with atypical chest pain. Electrocardiography demonstrated

Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

open access: yesAdvanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...

Nitric Oxide‐Releasing Catheters with Phenol‐Amine Catalytic Coatings for Improved Anti‐Inflammatory Performance

open access: yesAdvanced Healthcare Materials, EarlyView.
Tannic acid‐selenocystamine (TA‐SeCA) nanocoating enables stable, sustained catalytic nitric oxide (NO) release on catheter surfaces. This one‐step phenol‐amine coating improves catheter functionality by enhancing endogenous NO production, supporting vascular function, and reducing inflammation.
