title: Guideliner catheter facilitated percutaneous coronary artery intervention of an anteriorly displaced and heavily calcified right coronary artery.
abstract: Failure to deliver stents is one of the most common causes of procedural failure in contemporary percutaneous coronary intervention practice. The right coronary artery with an anomalous origin is an uncommon and challenging vessel for percutaneous intervention especially if this occurs in combination with heavy calcification. Choosing the appropriate guiding catheter is one important factor in determining procedural success. The technical difficulty of these anomalous vessels is reflected by the long procedure, fluoroscopy times, and high contrast volumes. Despite using the optimal guiding catheter, we may have difficulty advancing the stent in the distal part of the vessel due to the development of significant friction between the stent and the calcified vessel wall. We report a case of successful use of the Guideliner catheter (Vascular Solutions) for distal stent delivery in a patient with a right coronary artery with anomalous origin (anteriorly displaced) and heavy calcification.
