Successful percutaneous coronary intervention with GuideLiner   catheter for XXXX in the right coronary artery with anomalous origin from the left sinus of Valsalva: a case report.

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. CASE PRESENTATION: A 58-year-old Japanese @entity1 was admitted to our hospital complaining of worsening exertional @entity662 . He was suspected of having unstable @entity951 and underwent cardiac catheterization. We found a @entity432 in the mid-portion of his right coronary artery that originated from the left sinus of Valsalva. On the previous percutaneous coronary intervention, we failed to cannulate the guiding catheter to the anomalous orifice of the right coronary artery. Therefore, we decided to use the GuideLiner catheter for stable back-up support from the beginning. A 6Fr GuideLiner catheter was introduced into the right coronary artery by anchoring it coaxially with a semi-compliant balloon catheter. And we successfully deployed two drug-eluting stents by crossing over the posterior-descending artery. Final angiography demonstrated favorable dilatation of the @entity75 , and native blood flow in the right coronary artery was completely recovered. CONCLUSION: GuideLiner is a monorail-type " @entity1 " 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.
