Percutaneous intervention on anomalous circumflex coronary arteries - a single centre experience

摘要

Background: Anomalies of the origin and course of the circumflex artery are amongst the most common seen at coronary angiography. There is limited information regarding patient and procedural characteristics, technical feasibility and outcomes associated with percutaneous intervention (PCI) to these vessels. The aim of this study is to examine our experience with PCI to anomalous circumflex vessels and compare this to some aspects of percutaneous intervention on non-anomalous circumflex vessels. Methods: Over a 41 month period, 20 PCI procedures on anomalous circumflex vessels were identified and 1550 PCI procedures on non-anomalous circumflex arteries.Results: In 9 anomalous cases, the circumflex arose from the left coronary cusp, in 7 cases from the right coronary cusp, and in the remaining 4 cases from the proximal right coronary artery.
