title: [Coaxial catheterization with an ultra-flexible catheter (Tracker) in coronary angioplasty].
abstract: After experiencing problems of catheterisation during coronary angioplasty, the authors tried using a 3.2 F ultraflexible catheter with a 2.2 F tapered tip. In 2 patients, initial attempts at coronary catheterisation were failures but when this new catheter was used, angioplasty could be performed without any difficulty. This catheter was then used in 4 other patients and in all cases the Tracker enabled the operators to catheterise the coronary arteries and to perform angioplasty in 3 of the 4 cases. Therefore, this new ultraflexible catheter would seem to be a valuable alternative for catheterising particularly sinuous coronary arteries in which angioplasty is often technically difficult.
