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...

The coronary haemodynamic effects of nifedipine and glyceryl trinitrate were compared in 22 patients undergoing investigations for suspected coronary artery disease. Myocardial blood flow was estimated by the coronary sinus thermodilution technique. In sinus rhythm nifedipine increased mean coronary sinus flow from 135 ml/min to 152 m/min, and reduced arterio-coronary sinus oxygen difference fr...

BACKGROUND Ventricular tachyarrhythmias are the most common and often the first manifestation of coronary heart disease and lead to sudden cardiac death (SCD). Early detection/identification of acute myocardial ischaemic injury at risk for malignant ventricular arrhythmias in patients remains an unmet medical need. In the present study, we examined the sphingolipids level after transient cardia...

The coronary circulation of anesthetized dogs was tested for the presence of vascular waterfalls by manipulating coronary arterial and coronary venous pressures. The left main coronary artery and the coronary sinus were cannulated, and relationships between coronary artery pressure, coronary sinus pressure, and coronary flow were studied. Experiments were conducted during diastolic arrests, und...

BACKGROUND Left ventricular (LV) pacing through the coronary sinus is the standard approach for cardiac resynchronization therapy. When this route is unavailable, the alternatives have major limitations. LV endocardial pacing through the interventriuclar septum may offer a simpler solution. We describe an initial case series to demonstrate technical feasibility and to describe our refinement of...

Case report The patient had a history of coronary artery disease postcoronary artery bypass graft and was hospitalized for syncope due to atrial fibrillation with slow ventricular response, and underwent ventricular pacemaker implantation (VVIR mode). Under fluoroscopic guidance, a right ventricular screw-in lead was inserted via the cephalic vein. The course of the pacemaker leads deviated fro...

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...

INTRODUCTION Anomalous origin of coronary arteries from opposite sinus of Valsalva is rare finding. The incidence of anomalous origination of the left coronary artery from right sinus is 0.15% and the right coronary artery from the left sinus is 0.92%. The ectopic origin of left coronary artery or right coronary artery from opposite sinus depending on pathways and considering atherosclerotic ch...
