Stenosis in single coronary artery originating from right sinus of valsalva: asymptomatic upto sixth decade of life

Among all coronary anomalies, the prevalence of single coronary artery (SCA) originating from right sinus of Valsalva is 1.3%. Here, we report a rare case of a 60-years-old male serendipitously diagnosed with SCA originating from right aortic sinus with pre-pulmonic course of anomalous left coronary artery (LCA). His angiogram revealed 90% stenosis in distal right coronary artery with normal anomalous LCA. Thus, the patient was treated with percutaneous coronary intervention using a stent and was found stable post-procedure.
