Galiwango et al. (1) recently provided a beautiful coronary computed tomographic angiographic illustration of a rare anomaly, which they termed “the coronary collier.” Although this single coronary artery variant (arising from the right coronary cusp and coursing the entire atrioventricular groove before terminating in the anterior interventricular sulcus) is certainly uncommon, it is not “new” to the literature. This coronary artery anomaly was previously identified on the post-mortem examination of the late basketball star Pete Maravich (2). Histology revealed patchy scarring and interstitial fibrosis in the subendocardial regions of the anterior and apical left ventricle, without significant cellular infiltrate. The pathologic findings were thought to be consistent with chronic ischemia in the distribution of the terminal circulation (left anterior descending artery territory). The authors of this earlier paper concluded that this portion of the heart had a combined ischemic blood supply coupled with an excessive demand on the limited circulation. Perhaps a similar pathophysiology contributed to the chest pain symptoms reported in their 59-year-old female patient.
