Intermittent coronary sinus occlusion after coronary arterial ligation results in venous retroperfusion.
Coronary sinus occlusion retards necrosis of ischemic myocardium. To test the hypothesis that coronary sinus occlusion induces retrograde venoarterial flow, the coronary arteriovenous pressure gradient and the coronary arterial oxygen saturation were measured distal to a left anterior descending coronary artery ligature in dogs. In parallel, we constructed a mathematical model of known coronary...

Aim: To study the anatomy of the coronary venous system in cadaveric hearts, to ascertain various morphological features of the coronary sinus in order to compare male and female coronary sinus.In addition to provide anatomical basis for the cannulation of coronary sinus and its tributaries. Methods; The study was performed on 40 hearts from embalmed cadavers in different age group varies from ...
متن کاملUnroofed coronary sinus defect.
Subsequent echocardiogram showed a dilated right ventricle with moderate tricuspid regurgitation. There was pulmonary hypertension (estimated pulmonary arterial systolic pressure, 55 mm Hg). Transthoracic Doppler studies showed a left-to-right shunt with a shunt ratio of 2:1. However, the ductus arteriosus was not patent and there were no septal defects. The coronary sinus was dilated and there...
متن کاملAneurysm of the coronary sinus.
Two patients, an adult and a baby, with an aneurysm of the coronary sinus are described. This unusual anomaly was detected in the baby during angiographic investigations for congenital heart disease. The aneurysm was an unexpected postmortem finding in the adult. Although the adult died suddenly, there was no evidence that this could be linked to the presence of the aneurysm.
متن کاملArrhythmogenicity of the Coronary Sinus
The coronary sinus (CS) is the cardiac venous system that begins at its ostium in the right atrium and ends at the origin of the great cardiac vein.1,2,3 The major tributaries of the CS include the great cardiac vein (anterior cardiac vein), the left obtuse marginal vein, the posterior (or inferior) left ventricular vein, the middle cardiac vein, and the right coronary vein. In addition, atrial...
