We report our initial experience with an animal model, using a new mechanical catheter‐based dilatation system, the FullFlow (FF) catheter. The primary purpose of this study was to compare coronary flow achieved using the FF perfusion catheter and a traditional balloon angioplasty perfusion catheter. Baseline average peak velocity (APV) measurements were obtained using the FloWire Doppler guide wire. Either a Surpass Perfusion balloon (PB) or an FF catheter was advanced to a coronary segment. Doppler measurements were made before, during, and after full device expansion. Simultaneous heart rate, EKG, and blood pressure readings were recorded. Significant 36.1% and 29% reductions in mean APV were found for PB when comparing baseline to device‐up measurements and when comparing device‐down to device‐up measurements, respectively. In contrast, significant 12.2% and 18.5% increases were seen in mean APV for the FF. No significant differences were found in heart rate, systolic blood pressure, diastolic blood pressure, or ST‐segment changes. The FF system produces superior downstream coronary perfusion with side‐branch coronary patency compared with results using a contemporary perfusion balloon angioplasty catheter. Cathet. Cardiovasc.
