Percutaneous Coronary Intervention in Anomalously arising Coronary Arteries

ABSTRACT

Objective: Anomalous origin of coronary arteries (ACA) is rare. The objective of this communication is to describe the difficulties in angiographic recognition and challenges in percutaneous management. Methods: The material for this retrospective study was provided by contributing interventional cardiologists practicing in tertiary care centers. Results: From 2010 to 2019, 27 patients underwent percutaneous coronary intervention (PCI) for ACA. Four groups were encountered including anomalous origin from opposite sinus [left anomalous coronary artery from opposite sinus (L-ACAOS, n = 5), right anomalous coronary artery from opposite sinus (R-ACAOS n = 4)], origin of left circumflex from right sinus (n = 12), and origin of right coronary artery from posterior sinus (n = 6). The selection of a guiding catheter is the crucial step and a wide range of accessories was required to achieve an excellent outcome. Radial access may have an advantage in R-ACAOS, although the majority had a successful procedure from the femoral approach. Conclusion: Percutaneous management of patients with anomalous coronary arteries is challenging but can be accomplished with an excellent immediate outcome.
