In 100 patients who underwent coronary angioplasty with more than one
balloon catheter for a lesion, these over-the-wire balloon catheters
were changed by using a regular-length guidewire. In order to change
to another balloon, the inflation device was connected to the central
guide wire lumen of the catheter after pulling back the catheter until
the proximal end of the regular length guide wire disappeared. By
pulling back the balloon catheter from the guiding catheter by
applying a pressure with the inflation device, the balloon was taken
out of the guiding catheter leaving the wire in the coronary artery.
One hundred forty-nine of 163 attempted procedures were completed
successfully. Our technique helped in performing a fast, safe, and
reliable changing procedure compared to the procedure with an extended
guidewire.
