It was reported that the procedure was to treat a 75% stenosed, moderately calcified lesion in the mildly tortuous distal right coronary artery.
Following pre-dilatation, the 2.
25 x 18 mm xience sierra stent was advanced without resistance and deployed.
The stent balloon was dilated twice at 12 atmospheres.
It was seen on the angiography that contrast was leaking from the balloon during the third inflation at 16 atmospheres.
The stent was deployed without issue and apposition was confirmed with intravascular ultrasound (ivus) and the procedure was completed.
No resistance was felt with the balloon during removal.
The stent balloon was dilated outside the anatomy and a leak was observed.
There were no adverse patient effects and no clinically significant delay in the procedure.
No additional information was provided.
