title: Deep seating of 5 Fr. guiding catheter across the stenosis with 5 in 7 method was effective for severely calcified lesion.
abstract: A 57-year-old male with end stage renal disease underwent coronary angiography (CAG). The CAG revealed two vessel disease with severe calcification. A week after the percutaneous coronary intervention (PCI) to the left anterior descending coronary artery (LAD), we performed PCI to the right coronary artery (RCA). Because of the calcification, no devices could be crossed. We then performed 5 in 7 method using Heartrail ST01, and inserted it across the stenosis, with dilatation balloon at the distal RCA as anchoring. Finally we managed to implant two stents. We report that 5 in 7 method and deep seating of 5 Fr. guiding catheter were effective for the severely calcified lesion.
