A patient with chest pain and inferoseptal ischemia at Rubidium-82 Positron Emission Tomography (82RbPET) was revascularized in a stenosis in the LAD/D1 bifurcation, while a CTO RCA was left untreated. One-year follow-up with Seattle Angina Questionnaire and repeat 82RbPET revealed symptom relief and improved inferoseptal perfusion likely through LAD collateralization.

It is rare to detect single coronary arteries during angiography and rarer still to detect abnormal origins of the right coronary artery (RCA) from the left anterior descending artery (LAD). A 49-year-old man with hypertension and hyperlipidemia presented to our hospital with a chief complaint of exertion-induced chest pain in the month leading up to presentation. Inverted T-waves were seen in leads V1–V5 on the electrocardiogram, and coronary computed tomography (CT) demonstrated that all three major coronary arteries originated from the same ostium in the left sinus of Valsalva. An anomalous RCA arose from the LAD as a separate branch and then coursed anteriorly down the right atrioventricular groove. Coronary angiography showed a high-grade stenosis (>90%) in the proximal LAD and mid-distal RCA. The cardiology team discussed the treatment plan and consequently performed complete revascularization with percutaneous coronary intervention (PCI). The approach was successful, and at the 10-month follow-up, the patient was symptom-free and coronary CT showed no restenosis.
