Abstract Background  Anomalous aortic origin of a coronary artery (AAOCA) is a rare congenital disease associated with an increased risk of myocardial ischaemia, ventricular arrhythmias, and heart failure. Case summary  A 75-year-old Caucasian man was referred for invasive coronary angiography (ICA) due to atypical chest pain. Invasive coronary angiography demonstrated non-significant atherosclerotic disease of the left coronary artery and an anomalous origin of the right coronary artery (RCA); without selective intubation. Coronary computed tomography angiography (CCTA) revealed a right-AAOCA with interarterial and intramural course, and a soft plaque in the distal RCA. Subsequent physical-stress single-photon emissions computed tomography (SPECT) showed exercise-induced inferoapical myocardial ischaemia, giving a Class IC level of evidence for surgical correction of the AAOCA. Repeated ICA with selective R-AAOCA intubation confirmed an 80% distal atherosclerotic stenosis, which was treated with direct stenting. Subsequent invasive physiologic evaluation under maximal dobutamine-volume challenge (gradually increasing dose of dobutamine max. 40 μg/kg per body weight/min, 3000 mL ringer lactate and 1 mg atropine was given until the patient reached a maximum of 145 b.p.m.), revealed a haemodynamically non-relevant anomalous segment with a fractional flow reserve (FFR) of 0.91. A follow-up SPECT was normal, and the patient was completely symptom-free at 1 month. Discussion  We present the sequential diagnostic approach in a symptomatic patient with a right anomalous coronary artery and concomitant atherosclerotic disease. Using this approach, the patient could be deferred from guideline recommended open-heart surgery of the AAOCA, as direct invasive dobutamine/volume FFR revealed haemodynamic non-relevance of the anomalous segment after stenting the concomitant atherosclerotic stenosis in the distal segment within the same coronary artery.

AbstractWe report the case of an adolescent who was presented with long-standing exertional symptoms, and was diagnosed with an anomalous right coronary arterial origin arising above the commissural junction between the left and right aortic sinus, with inter-arterial and intramural compression. The precise origin of this lesion outside the aortic sinuses is unusual, and multi-detector computed tomography gave excellent definition and spatial resolution of the anomalous origin and course. It is crucial to have a high index of suspicion of exertional symptoms, as sudden death may be the first manifestation of an anomalous coronary artery.

Coronary angiography and dual-source computed tomography are complementary methods in diagnosis of significant stenosis of the right coronary artery originating from the left aortic sinus

AbstractAnomalous origin of the right coronary artery from the contralateral aortic sinus is a rare but potentially fatal congenital abnormality. We analyzed 8.066 consecutive coronary angiograms and found 4 cases demonstrating this anomaly. In 2 cases the right coronary artery was without significant atherosclerotic lesions and coursed between the aorta and pulmonary trunk. In the 2 other cases the right coronary artery was significantly stenosed. In the last case, diagnosis was based on angiographic and dual-source computed tomographic examinations. Dual-source computed tomography showed precisely the origin and course of the right coronary artery between the ascending aorta and pulmonary artery. Moreover, stenoses of the anomalous coronary artery were depicted. Subsequent coronary interventions required modification of the Amplatz left guiding catheter, which enabled a sufficient support even for coronary artery stenting. Both methods seem to be complementary in the diagnostic and therapeutic process of this coronary anomaly.
