The Magnum wire for percutaneous coronary balloon angioplasty in 723 patients.
The experience of the use of the Magnum wire in a single center is reported. Percutaneous balloon coronary angioplasty, using the Magnum 0.021 inch wire, was attempted in 723 patients with 850 lesions; of these, 453 (53%) were chronic total occlusions and 50 (7%) recent occlusions of less than 24 hours (patients presenting with acute myocardial infarction). The overall technical success rate per lesion was 655/850 (77%). It was 255/280 (91%) for non-total lesions, 311/453 (69%) for chronic total occlusions, 53/67 (79%) for functional (TIMI grade I) occlusions, and 36/50 (72%) for recent occlusions. Clinical success was achieved in 196/232 patients (84%) with non-total lesions, in 292/436 (67%) with total chronic occlusions, in 49/65 (75%) with functional occlusions, and in 34/50 (68%) with recent occlusions. Complications (significant creatine kinase rise, new Q-wave infarction, need for coronary bypass surgery or in-hospital death) occurred in 7% (3% if patients presenting with unstable ischemic syndromes were excluded from the analysis). These data confirm that the use of the Magnum wire has success rates competitive with other systems both in setting of chronic total occlusion and in that of routine percutaneous transluminal coronary angioplasty.
