| Popis: | Percutaneous transluminal coronary angioplasty (PTCA) for total occlusions frequently fails, because the guidewire fails to pass the occlusion. With the use of the Probe exchange catheter (PEC), however, stiffness of the guidewire is increased and a higher pushability is obtained in order to manipulate the guidewire beyond the lesion. Once the guidewire has passed, the PEC is advanced and a non-over-the-wire dilatation catheter can be introduced through the PEC. This paper describes the technique in a representative case. The results of this technique in 19 consecutive patients with class III-IV/IV(NYHA) angina due to an occluded coronary artery are presented. In 16 patients the PEC reached the lesion (84%) and in all these patients the guidewire could pass the occlusion. A successful PTCA was performed in 14 patients (74%). |
