Multivessel transradial percutaneous coronary angioplasty in a single coronary artery originating from the right sinus of Valsalva.

Percutaneous coronary intervention in patients with an anomalous coronary artery is technically challenging. Selective cannulation and coaxial positioning in the anomalous artery and optimum stability during the procedure are pivotal for successful completion of the procedure. Selection of the appropriate guide catheter is of paramount importance in these situations. In patients with congenital coronary artery anomalies, increasing use of multidetector computed tomography for cardiac imaging may yield diagnostic information not obtained with coronary angiography. Axial, multiplanar, and three-dimensional volume-rendered reconstructions aid in detecting and interpreting such anomalies and in selecting appropriate hardware during percutaneous coronary intervention in these patients. We report a case of successful stent implantation in the right coronary artery and proximal circumflex coronary artery in a patient with a single coronary artery arising from the right sinus of Valsalva.
