CIRCULATION OF BLOOD THROUGH HEART AND MAJOR VESSELS

coronary circulation

Movement of blood through the vessels of the heart, specifically from the ascending aorta to the epicardial coronary arteries to the penetrating arteries of the myocardium, the coronary arterioles, capillaries, veins, coronary sinus, and into the right atrium. A few of the small veins open directly into the atria and ventricles.

Finally, compared with CCA, MSCT is unable to accurately assess the speed and direction of blood flow in the coronary circulation and across stenotic lesions (64).
Adenovectors are also considered to be significantly more efficient than naked plasmid DNA for gene transfer; and naturally-occurring biological receptors for adenovectors are believed to facilitate its binding to a broad area of heart muscle supplied by the infused coronary circulation. Employing this readily-accessible coronary delivery route to the myocardium avoids the need for any mechanical devices or approaches that require entry into the heart chambers or piercing of the surrounding heart muscle, or that result in delivery and gene expression concentrated along needle tracks in the injected myocardium.

SNOWMASS COLO -- Sirolimus-eluting stents show some promise for the treatment of obstructive superficial femoral artery lesions, although it must be said the results aren't nearly as impressive as in the coronary circulation.
More recently, clinical studies using adenoviral vectors encoding angiogenic factors, VEG[F.sub.121]) and FGF4, have targeted coronary circulation. The ongoing study with FGF4 has the benefit of randomization, but carries the risk of administering a first-generation adenoviral vector directly into the coronary circulation.
Like all other body tissues, the heart must have its own blood supply, delivered via the coronary circulation system.
Dissection occurred in the left coronary circulation in 32 (66.7%) and right coronary circulation in 16 (33.3%) patients.
Given the ecological importance of the cougar, the functional significance of the coronary circulation, the scarcity of descriptions related to wild felids, and the controversial coronary dominance in felids, the objective of this study was to describe the anatomy of the coronary arteries and their main branches in P.
