• Coronary flow measurements in the intact animal and in man have been based principally on the amount of the coronary sinus drainage. Two assumptions are involved in the use of the coronary sinus drainage as an index of total and of left ventricular coronary flow: (1) The coronary sinus flow is a fixed percentage of total coronary flow, and (2) it represents all or a constant portion of the ve...

A 56 year old man was admitted to our center for further evaluation of typical chest pain of ten months' duration. Selective coronary angiography was done and showed a sewing needle-like foreign body which was lying in very close proximity to the anatomic location of the right coronary artery. At operation two pieces of sewing needles were removed, one from the coronary sinus and the other...

Coronary artery anomalies are found in 0.6% to 1.55% of patients who undergo coronary artery radiographic tomography [1-5] and the increasing use of diagnostic coronary angiography (CAG) is uncovering even more such abnormalities. Anomalous origin of the left main coronary artery (LMCA) from the right sinus of Valsalva is reported in 0.09% to 0.15% of cases [1-6]. Indeed, most coronary anomalie...

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 ...

A 15-year-old girl was admitted for repair of partially unroofed coronary sinus syndrome. A preoperative echocardiographic study disclosed the dilated coronary sinus and a draining blood flow into the right atrium from both the left atrium and the end of the coronary sinus. At surgery, the distal portion of the coronary sinus roof was found to be absent. The defect was repaired through the coro...

The selective administration of dopamine, norepinephrine, epinephrine and isoproterenol, into the coronary sinus region of the dog heart produced so-called coronary sinus rhythm, indicating the appearance of deep inverted P waves and frequently accompanied by an acceleration of pacemaker activity of the coronary sinus region. These effects of catecholamines were not influenced by atropine and t...

The presence of anomalous coronary arteries is observed in approximately 1% of patients undergoing coronary angiography (CAG). In these patients, identification of the stenotic ostium and revascularization is difficult, particularly in the emergency setting of primary percutaneous coronary intervention (PCI). Among the congenital coronary anomalies, separate anomalous origin of all the coronary...

AIMS To evaluate the correlation between the coronary sinus flow and the infusion volume in the coronaries and assess the performance of coronary sinus flow in predicting coronary artery occlusion in an isolated pig heart. MATERIAL AND METHODS The coronary sinus flow was measured in 16 isolated pig hearts by pulsed Doppler ultrasound. The correlation between the coronary sinus flow and the in...

The echocardiographic features of the enlarged coronary sinus are described in eight patients with a left superior vena cava draining to the coronary sinus and two patients with total anomalous pulmonary venous connection to the coronary sinus. The diagnosis was confirmed in each patient by cardiac catheterization and surgery. On the M-mode echocardiogram, a dense echo was present posterior to ...
