An 80-year-old man received stent implantation for severe stenosis of the right renal artery. During the procedure, the proximal edge of the stent was successfully positioned at the ostium of the renal artery. After 6 months, follow-up renal angiography showed transverse stent fracture without restenosis.

With the improvement of percutaneous coronary intervention (PCI), the miniaturization of devices has continued. We have developed a virtual 2-Fr system that is the slenderest system to date. The outer diameter of the system using a 4-Fr sheathless guiding catheter is ∼2-Fr size.

Background: Although drug-eluting stents dramatically reduce revascularization after percutaneous coronary intervention (PCI), it is still unclear whether they increase the risk of stent thrombosis. Late stent thrombosis (>30 days) was a very rare complication after bare metal stent implantation. Four cases of confirmed late angiographic stent thrombosis (LAST) after sirolimus-eluting stent (SES) implantation are presented and the incidence, promoting factors and outcomes of such cases in Japan, where clopidogrel has not been approved, are described.

Stenting of anomalous coronary artery is technically challenging both from the femoral and radial approaches because of difficulty in cannulating the artery by the guiding catheters with enough back-up support for delivering the stent. We report the first case in the literature of transradial coronary angioplasty and stenting to an anomalous left main coronary artery originating from the right sinus of Valsalva. Left Amplatz guidance from the radial approach provided an adequate platform to advance the stent using a dummy guidewire technique, and a self-expandable RADIUS stent was successfully deployed in a tortuous lesion of the anomalous artery.
