It has been reported that this type of anomaly is observed in approximately 10% of the population with an anomalous An anomalous origin of the right coronary artery (RCA) from the left sinus of Valsalva is uncommon but occasionally noted in association with potentially serious sequelae such as sudden death. Keywords: Anomaly of coronary artery, Complex coronary intervention, GuideLiner, Left sinus of ValsalvaĪnomalies of the coronary artery are a diverse group of congenital disorders that have been investigated by many authors. Final angiography demonstrated favorable dilatation of the target lesion, and native blood flow in the right coronary artery was completely recovered.Ĭonclusion: GuideLiner is a monorail-type "child" support catheter that facilitates coaxial guiding catheter engagement and an appropriate back-up force, achieving successful device delivery to target lesions in this kind of complex percutaneous coronary intervention. And we successfully deployed two drug-eluting stents by crossing over the posterior-descending artery. A 6Fr GuideLiner catheter was introduced into the right coronary artery by anchoring it coaxially with a semi-compliant balloon catheter. Therefore, we decided to use the GuideLiner catheter for stable back-up support from the beginning. On the previous percutaneous coronary intervention, we failed to cannulate the guiding catheter to the anomalous orifice of the right coronary artery. We found a subtotal occlusive lesion in the mid-portion of his right coronary artery that originated from the left sinus of Valsalva. ![]() He was suspected of having unstable angina pectoris and underwent cardiac catheterization. Introduction: Because of the unusual anatomy of an anomalous origin of the right coronary artery from the left sinus of Valsalva, selective cannulation of the guiding catheter in percutaneous coronary intervention for these cases is always challenging.Ĭase presentation: A 58-year-old Japanese man was admitted to our hospital complaining of worsening exertional chest pain.
