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...

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...

CARDIAC resynchronization therapy with the placement of a left ventricular pacing electrode in the coronary sinus has been shown to be an effective treatment in selected patients with symptomatic left ventricular dysfunction. Coronary sinus leads can be removed with relative ease because of their small diameter and relatively poor fixation mechanisms. However, removal of coronary sinus electrod...

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 ...

BACKGROUND The pressure waveform of coronary sinus in human hearts has never been well described. Retrograde cardioplegia perfusion has become a popular method of myocardial protection in recent years, and identification of the pressure waveform of the coronary sinus might help intubate the coronary sinus in retrograde cardioplegia perfusion by differentiating it from that of the right atrium. ...

anomalies of origin, course, and distribution of coronary arteries, including single coronary artery, are well known in patients with tetralogy of fallot. however, to the best of our knowledge, there is no published case report of pentalogy of fallot with a single coronary artery. herein, we introduce a 22-year-old female patient diagnosed via echocardiography and cardiac catheterization preope...
