During the performance of 200 routine coronary angiograms, 5 patients with anatomical variants of the origin of the left circumflex coronary artery were found. The origin and course of the left circumflex coronary artery is described in each case. The practical importance of these variant vessels in patients being considered for coronary artery surgery is emphasized.

We here present the case of a rarely seen anomalous origin and retropulmonary course of the left circumflex artery from the proximal right coronary artery. The patient suffered from coronary ischemia due to stenotic lesions both in the aberrant circumflex coronary artery and in the first and second diagonal branches. Coronary bypass operation was performed.

Although coronary artery anomalies may cause some clinical symptoms, most are incidentally discovered as benign findings on coronary angiograms. A circumflex coronary artery anomalously originating from the right sinus of Valsalva is the most common coronary anomaly. However, a double circumflex coronary artery, both stenotic in their mid portions, resulting in symptomatic heart failure is a ra...

A50-year-old man died suddenly while exercising on a treadmill at a local health club. He had no known previous cardiac history. During autopsy, a radio-opaque silicone compound was injected into the coronary arteries. The explanted heart was then imaged by electron-beam computed tomography (EBCT) using 3-mm slices. A complete 3D reconstruction was then obtained using commercially available sof...

OBJECTIVE To study in swine the hemodynamic changes secondary to the use of stabilizers for off-pump coronary artery bypass graft surgeries by means of both a suction device "Octopus" and a compression device (Speroni). METHODS Ten swine underwent median sternotomy. Monitoring of ECG, continuous cardiac output, mean arterial pressure, mean pulmonary artery pressure, mean right and left atrial...

We quantitatively analyzed blood flow through the major arteries supplying the pig’s femoral head during various hip positions and following ligation of various vessels in order to identify the vascular abnormalities which may be responsible for the development of avascular necrosis during the treatment of developmental dysplasia of the hip. Our findings reveal that a decrease in total blood fl...

background: myocardial infarctions at different locations have been related to different sets of risk factors. this study was designed to examine the association between cardiovascular risk factors and specific coronary artery calcification (cac). methods: the study population comprised 573 postmenopausal women selected from a population-based cohort study. established vascular risk factors wer...

Variant origin of lateral circumflex femoral artery (FA) is important during harvesting of anterolateral thigh flaps, aortopopliteal by-pass, coronary artery grafting, and vascularised iliac transplant. The frequencies of variant origins display ethnic variations, but reports from black Africans are scarce. This study, therefore, aimed to describe the variant origins of lateral circumflex FA in...

BACKGROUND We sought to determine whether location of the second internal thoracic artery (ITA) graft used for bilateral ITA grafting affects mortality and morbidity of patients with 3-system coronary artery disease and to identify factors associated with second ITA location. METHODS AND RESULTS From January 1972 to June 2006, 3611 patients with 3-system coronary artery disease underwent bila...
