It was reported that the procedure was to treat a de novo lesion located in the proximal right coronary artery that was 90% stenosed.
The nc trek balloon catheter was advanced to the lesion without issue.
The balloon was inflated one time to 12 atmospheres (atm) for ten seconds but took more time than usual to deflate.
During removal, resistance was met inside the stent, but the device was removed without further issue.
There were no reported adverse patient effects and no clinically significant delay in the procedure.
The procedure was completed with a non-abbott device.
No additional information was provided.
