|A 67-year old male was presented with effort chest
pain for 3 months. Risk factors included hypertension and hypercholesterolemia.
Echocardigraphic examination was normal and treadmill test was positive
at stage 3.
|Baseline Coronary Angiography
|The diagnostic coronary angiography revealed a severe
stenosis in the proximal segment of right coronary artery (Figure
1). Left coronary angiography was normal.
|A 7F Judkins guiding catheter was engaged at the
ostium of the RCA. A Floppy guidewire was placed into the RCA. The lesion
was predilated with a 2.5 x 20 mm conventional balloon at 10 atm (Figure
2). After predilatation, the lesion was stented with a 3.0 x 13 mm sirolimus-eluting
stent at 20 atm (Figure
3). After stent implantation, adjunctive high pressure dilatation with
a 3.5 x 9 mm balloon at 16 atm was performed for angiographic optimization.
Final angiography showed well deployed stent without residual stenosis or
dissection and the presence of TIMI 3 flow (Figure
| Six-month follow-up angiography showed that the
stent was completely fractured at the point of stent shaft. However, both
the stent-covered and fracture sites were patent (Figure
