Korean Circulation Journal, 2009 Anomalous origin of the right or left coronary artery from the contralateral sinus of Valsalva is often asymptomatic, but many patients, particularly young ones, present with sudden death or myocardial ischemia without symptoms.

Accidental finding of a giant right coronary artery aneurysm associated with a fistula to the right atrium [PDF]
, 2014 Coronary artery fistulae are uncommon but may be haemodynamically significant, being an incidental finding in 0.1-0.2% of coronary angiograms. Even rarer is the association between fistulae and non-atherosclerotic coronary artery aneurysms.

A data-driven Reduced Order Method for parametric optimal blood flow control: application to coronary bypass graft [PDF]
arXiv, 2022 We consider an optimal flow control problem in a patient-specific coronary artery bypass graft with the aim of matching the blood flow velocity with given measurements as the Reynolds number varies in a physiological range. Blood flow is modelled with the steady incompressible Navier-Stokes equations.

, 1963 Studies of survival following ligation and gradual occlusion of the right coronary artery 5 mm. from its ostium have been made in 95 pigs. The pig was selected for the experiments because its coronary artery distribution closely resembles that of the ...

American Journal of Physiology. Heart and Circulatory Physiology, 2008 Despite having almost identical origins and similar perfusion pressures, the flow-velocity waveforms in the left and right coronary arteries are strikingly different. We hypothesized that pressure differences originating from the distal (microcirculatory)
