Cx. Pimentel et al., THE USE OF THE TRACKER CATHETER AS A GUIDEWIRE SUPPORT DEVICE IN ANGIOPLASTY OF ANGULATED AND TORTUOUS CIRCUMFLEX CORONARY-ARTERIES, The Journal of invasive cardiology, 7(3), 1995, pp. 66-71
Marked angulation and tortuosity of the coronary arteries, particularl
y the circumflex, can limit coronary angioplasty. Despite the use of a
dequate guide catheter support and high performance guidewires, it is
often difficult or even impossible to reach the distal segment of the
target vessel with the guidewire. We describe three cases of successfu
l complex circumflex coronary artery angioplasty where guidewire advan
cement through proximal angulated and tortuous anatomy was facilitated
by the Tracker-18 Hi-Flow catheter after failure of conventional angi
oplasty hardware.
