“…The special configuration of the ostium and the elastic type artery in the beginning of the RC (small aorta) probably keeps the ostium and the artery open during the cardiac cycle. The orifice was not collapsed as a slit-like ostium and there was no diastolic entrapment from the initial investment in aortic adventitia as referred to in the literature (Cheitlin et al, 1974;Roberts et al, 1982;Mahowald et al, 1986;Ness and McManus, 1988;Lipsett et al, 1994;Rinaldi et al, 1994;Becker, 1995).…”

Anatomic and postmortem angiographic findings of a previously unreported case of ectopic origins and unusual courses of the right coronary (RC) artery and the left coronary (LC) artery were demonstrated. This specimen was unique among 450 angiographies and 60 corrosion castings of the human hearts examined in this study. The ostium of the RC artery was pocket-like, located in the left aortic wall at roughly 180°to the long axis of the ascending aorta and 19 mm above the rim of the sinotubular junction (SJ). Initially, the RC runs to the right and downward, passing high in the cleft between the aorta and the pulmonary trunk, thereby avoiding a possible compression from them. The ostium of the LC faced upward and originated from the left aortic wall 7 mm above the SJ. The LC ran to the left and downwards for 16 mm until its division. Histologically, the first 11 mm of the RC were elastic. This observation, together with its high course between the great vessels, combined to make this case benign. The best x-ray projections to show the characteristic findings of the present case were anteroposterior and lateral, which were of practical importance for the correct determination and interpretation of this case. The cardiac surgeon should be aware that high cannulation will be required to locate the RC to avoid accidentally cross-clamping or transecting the vessel during surgery where this anomaly may be encountered.

“…8 The majority of these complications may be exacerbated during or immediately after exercise, as exercise leads to compression of coronary arteries as well as increasing the preexisting angulation of the proximal portion of the anomalous vessel. 9 Clinical presentation of these patients ranges from asymptomatic for non-significant anomalies to syncope, chest pain, myocardial infarction and sudden cardiac death in significant anomalies. Diagnosis of anomalous coronary arteries may be suggested by echocardiography and a high index of suspicion.…”

“…These events are probably because of myocardial ischaemia even in the absence of atherosclerosis. An association with coronary events has been well documented for the case of a left coronary branches arising from a single RCA and coursing between the aorta and the pulmonary artery (intertruncal course) [9,10]. The pathophysiological mechanism in this scenario is most likely a transient occlusion of coronary artery branches because of an increase in blood flow through the aorta and the pulmonary artery resulting in kinking or pinching of the vessel [11].…”

This is the first description of treatment with coronary stenting of a patient with a single coronary artery originating from the right Sinus Valsalvae and suffering from acute inferior myocardial infarction. Angiography showed the following: the right coronary artery (RCA) had a normal course, whilst the left anterior descending (LAD) as well as the left circumflex (LCX) branches both originated separately from the proximal RCA, which served as a common mixed trunk. The LAD crossed to the left in front of the right ventricular outflow tract, whilst the LCX, taking a retroaortic course to the atrioventricular groove, had a distal occlusion. According to an anatomically based classification considering all imaginable variations, this configuration corresponds to a II-D-1 pattern, which previously has been described only in a single postmortem case. After the LCX was reopened with a guide wire, a coronary stent was successfully inserted, resulting in TIMI-3 flow. Recovery was uneventful.
