It was reported that the procedure was to treat a moderately calcified, 80-99% stenosed lesion in the mid anterior interventricular artery (iva).
A 2.
5x20mm trek rx balloon dilatation catheter (bdc) was advanced to the target lesion for pre-dilatation.
The initial inflation was to 14 atmospheres (atm) and held for 14 seconds.
The bdc was then moved a few millimeters to pre-dilatate a more proximal part of the lesion when resistance was noted.
The second inflation was to 20 atm and held for 10 seconds.
Subsequently, imaging was performed, and it was noted that the balloon only partially deflated.
The balloon was able to be successfully removed from the anatomy while it was partially inflated.
There was no adverse patient effect and no clinically significant delay in the procedure.
