Balloon inflation caused by contrast injection through the guiding catheter: an unusual observation during coronary angioplasty.
Balloon inflation caused by contrast injection through the guiding catheter has been observed during several angioplasty procedures. The phenomenon is observed when employing an 8F USCI guiding catheter in combination with an ACS dilatation catheter. Two cases demonstrating the phenomenon are described in detail, together with an in vitro experiment that illustrates and quantifies the mechanism.
