Once in position, the balloon is carefully inflated so as to compress the obstructing plaque & restore blood flow. Appropriate drugs may be given at the same time. The whole operation, & especially the patient's vital functions, are closely monitored by a technician in an adjacent control room. Montefiore Medical Center, NYC.
