Abstract
ObjectiveTo assess the technical challenges in percutaneous coronary intervention of Anomalous right coronary artery arising from the left sinus of valsalva. MethodsBetween year 2008 and 2012, a total of 17 patients underwent PCI for an angiographically significant lesion in the right coronary artery of an anomalous origin in the LSOV. Their procedure details such as usage of catheters, radiation time, amount of contrast used were assessed. ResultsA total of 17 patients with anomalous right coronary artery underwent PCI during the above mentioned period. 8 patients had type A origin, 3 had type B origin and the remaining 6 had type C origin. Type A origin RCA were successfully cannulated in 6 patients with Judkins left 5.0 and in 2 patients using Judkins left 4.0. Extra back up (EBU) 3.5 were doing well in 2 patients of Type B origin and the remaining one patient was successfully cannulated using Judkins left 4.0. In type C origin 4 patients had successful cannulation with Amplatz Left 1.0, 1 patient with Amplatz Left 2.0 and 1 patient with Judkins left 4.0. The mean fluoroscopic time was 20.7 min and amount of contrast used was 210 ml. ConclusionPCI of anomalous RCA origin from LSOV requires appropriate guide catheter selection according to the anatomy of origin for successful cannulation and to reduce the contrast usage and radiation exposure.
