Over recent decades, the numerous coronary revascularisation procedures performed either by percutaneous coronary intervention (PCI), or coronary bypass surgery has led to an increasing number of patients who are no longer eligible for additional revascularisation procedures. This number of patients is expected to rise even further in view of an increase in life expectancy in patients with coro...

Anomalous origin of coronary arteries is generally asymptomatic and a rare disease. However, some cases can cause severe life-threatening events such as myocardial ischemia, arrhythmia, and acute myocardial infarction. We describe a case of a single coronary artery arising from the right sinus of Valsalva in a 48-year-old female patient with a complaint of stable angina pectoris and palpitation...

A clinical case of successful radiofrequency ablation ventricular tachycardia with para-Hisian localization the substrate by access from right coronary sinus Valsalva is presented.

OBJECTIVE To evaluate the Coronary Flow Reserve in the Coronary Sinus through transesophageal Doppler echocardiography in normal subjects. METHODS We obtained technically adequate flow samples for analysis in 10 healthy volunteers (37+/-8 years, 5 men) with no history of heart or systemic disease and with mean left ventricular mass index by transthoracic echocardiography of 87+/-18 g/m2. Coro...

BACKGROUND A growing population of patients lives with severe coronary artery disease not amenable to coronary revascularization and with refractory angina despite optimal medical therapy. Percutaneous reduction of the coronary sinus is an emerging treatment for myocardial ischemia that increases coronary sinus pressure to promote a transcollateral redistribution of coronary artery in-flow from...

An electrophysiological study was performed on a 39-year-old woman with recurrent palpitations. She initially presented in 1985 with atrial fibrillation, ventricular preexcitation, and a rapid ventricular response. At that time, she underwent open heart surgery, and mapping demonstrated multiple posteroseptal and left free wall accessory pathways. Accessory pathway conduction was abolished surg...

A 58 year old man with a history of cerebral infarction was admitted to hospital with chest discomfort and dyspnoea. He had no history of precordial chest discomfort. Angiography and left ventriculography showed that coronary fistulas connected the coronary sinus with the left circumflex and right coronary arteries. His coronary sinus did not communicate with the right atrium, draining instead ...

-----------------------------------.... Retrograde coronary sinus perfusion may provide equal if not better myocardial protection than antegrade cardioplegia during certain heart surgeries. The coronary venous system can be divided into the greater and lesser systems and veno-venous and arterio-venous anastomoses. Venous drainage varies greatly and retrograde coronary sinus perfusion depends on...

MANY excellent reviews of coronary arteriovenous fistulas have recently appeared in the literature.1 2 In the majority of these fatal cases, death was attributed to congestive heart failure. Rupture of the eoronary sinus as a coinplication of a coronary arteriovenous fistula has not, to our knowledge, been reported. The present case is thought to be unique in that the fistula was accompanied by...

Left ventricle-coronary sinus fistula and left ventricular pseudoaneurysm are unusual and frightening complications after mitral valve replacement. A 27-year-old female patient underwent mitral valve replacement 5 years previously and trans-thoracic echocardiography showed an outpouching lesion at the atrioventricular groove. It was difficult to differentiate whether the lesion was a left ventr...
