✦ Synopsis

The conus artery has long been recognized as an important source of collateral blood supply to a significantly diseased left anterior descending artery. This artery which arises 50% of the time from a separate orifice in the right sinus of Valsalva may also provide collateral circulation to a diseased right coronary artery. To date, there have been no reported instances of the conus artery supplying collateral flow to a totally occluded circumflex artery. In this report we describe such a case in a patient with severe three vessel disease. The implications of such a finding in patient management are also discussed.

We report a case of a 39-year-old woman with an upper posterior mediastinal tumor. The tumor was demonstrated by echocardiography and further defined by computerized tomography and magnetic resonance imaging. The tumor was fed by a large atrial branch of the left circumflex artery.

## Abstract Two direct branches of the brachiocephalic artery are frequently present in the dog. These are described in 33 dogs and their incidence recorded. One supplies the lower cervical trachea and esophagus and the other the thymus gland and sometimes the pericardium. Suggested names are β€œTrac
