The cardiovascular professional may be involved in their angiographic diagnosis, fimctional assessment and eventual endovascular treatment. A complete angiographic definition is mandatory in order to understand the functional effects and plan any intervention in CAAs： computed tomography and magnetic resonance imaging are useful non-invasive tools to detect three-dimensional morphology of the anomalies and its relationships with contiguous cardiac structures, whereas coronary arteriography remains the gold standard for a definitive anatomic picture. A practical idea of the possible functional sig- nificance is mandatory for deciding how to manage CAAs： non-invasive stress tests and in particular the invasive pharmacological stress tests with or without intravascular ultrasound monitoring can assess correctly the functional significance of the most CAAs. Finally, the knowledge of the particular endovascular techniques and material is of paramount importance for achieving technical and clinical success. CAAs represent a complex issue, which rarely involve the cardiovascular professional at different levels. A timely practical knowledge of the main issues regarding CAAs is important in the management of such entities.展开更多

Coronary anomaly will further increase difficulties in performing PCI for the patient. We present such a case as ostial occlusion of an right coronary artery with high takeoff. A 77-year-old male was referred to our institution with a diagnosis of non-ST elevated acute myocardial infarction. Selective coronary angiography and nonselective ascending aortography could not identify the origin of the right coronary artery. Multi-slices computed tomography showed RCA ostial totally occluded. A successful PCI was performed and a perfect final result was achieved utilized with many tips and tricks, including buddy wtre technique and focused-force angloplasty（J Genatr Cardio12009, 6：189-192）.展开更多
