Capillary blood flow enters venules that join to form cardiac veins that drain into the coronary sinus on the posterior side of the heart which drains into the right atrium There are also anterior cardiac veins and T hebesian veins drain directly into the cardiac chambers The coronary circulation consists of three main arteries LAD LCx and RCA and one main vein the coronary sinus The most exciting feature of this regional circulation is its ability to autoregulate its blood flow in a way which permits the heart to massively increase its metabolic demand As myocardial oxygen extraction is already quite

With transesophageal echocardiography color flow mapping identified coronary sinus flow in all patients Coronary sinus flow velocity could be quantified with pulsed Doppler in 25 63 of 40 patients Figure 2 C Failure to measure flow velocity adequately resulted from the inability to maintain the sample Regulation of Blood Flow into the Right Atrium The coronary sinus is responsible for delivering deoxygenated blood into the right atrium where it joins blood returning from the systemic circulation via the superior and inferior venae cavae The opening of the coronary sinus into the right atrium is guarded by a small valve the
Recall that blood returning from the systemic circuit enters the right atrium Figure 20 5 2 via the superior and inferior venae cavae and the coronary sinus which drains the blood supply of the heart muscle These vessels will be described more fully later in this section At rest the mean coronary sinus blood flow did not differ from that of controls but after maximal coronary artery vasodilation with intravenous dipyridamole CFR was significantly reduced coronary arteriograms were normal and endomyocardial biopsies showed fibrosis and vascular lesions with concentric intimal hypertrophy 38

The coronary sinus is the largest cardiac venous structure It returns the majority of the blood supply for the left ventricle to the right atrium The coronary sinus courses along the posterior wall of the left atrium into the left atrioventricular groove It The Thebesian valve prevents regurgitant blood flow from the right atrium from entering the coronary sinus during diastole 3 As the major tributary of the greater cardiac venous system the coronary sinus returns approximately 55 of the coronary blood supply into the right atrium
Coronary sinus ASD i e unroofed coronary sinus is a defect in the atrial wall that allows blood to flow from the left atrium to right atrium through the coronary sinus Explore the coronary sinus origin course tributaries and its function of delivering deoxygenated blood from the myocardium to the right atrium The coronary sinus is located in the posterior portion of the coronary sulcus on the diaphragmatic or posterior surface of the heart The coronary sinus empties directly into the right atrium near the conjunction of the posterior interventricular sulcus and the coronary sulcus crux cordis area located between the inferior vena cava and
