Objectives: With the development of PCI techniques, the indications for stents have been expanding as well. On the other hand, we often encounter the situations where deploying a stent/stents by the conventional method is technically challenging. We report a novel stent delivery system using a newly developed 4Fr. straight catheter with Mother‐and‐Child method. Methods and results: We collected the data on coronary angioplasty in which we experienced the difficulty to deliver coronary stents and used 4Fr. KIWAMI ST01. The case number amounts to 32 cases over a six‐month period from October 2009 through March 2010;76:919‐–923. The angioplasty was performed for lesions in the RCA in 9 patients (28%), lesions in the LAD in 15 patients (47%), lesions in the LCX in 5 patients (16%), lesions in the saphenous vein grafts in 2 patients (6%), and lesions in the internal thoracic artery (LITA) grafts in 1 patient (3%). And the reasons for the difficult stent delivery by the conventional methods were as follows: severe calcification in 12 patients (37%), intense tortuosity in 7 patients (22%), poor backup support for guide catheter in 8 patients (25%), and trapping of the stent proximal to the target lesion in 5 patients (16%). The dislodgment of stent did not happened in all cases. Conclusions: KIWAMI® ST01 stent delivery system is feasible, safer, and effective in cases where stent delivery is difficult by the conventional method. © 2010 Wiley‐Liss, Inc.
