heal.abstractPURPOSE: To compare the damage caused by vibrating guidewire manipulation and conventional guidewire manipulation of soft coronary wires in normal sheep coronary arteries. METHODS: Using an intact sheep model the two methods of passing a coronary guidewire down a normal coronary artery under fluoroscopic screening control were studied. The resulting arterial damage caused by the two techniques was studied histologically. The severity of damage was scored from 1 (no damage) to 4 (severe damage) and expressed as: (a) percentage of damaged sections, (b) mean damage score per section and (c) percentage of sections suffering the most severe degree of damage (scores 3 and 4). RESULTS: One hundred and sixty-eight sections were studied. The percentage of damaged sections was lower in the vibrating guidewire group (p = 0.004). The mean damage score and the percentage of sections with a damage score of 3 or 4 were smaller in the vibrating guidewire group than in the conventional guidewire manipulation group (p = 0.001 and p = 0.009, respectively). CONCLUSIONS: Both methods of guidewire manipulation cause identifiable vascular damage. The extent and severity of damage appear greater when the guidewire is manipulated manually.en
