Choice PTTM guidewire for recanalization of total occlusive coronary arteries

Objective: To evaluate the therapeutic effects of 0. 014" Choice PTTM wire in chronic total occlusion angioplasty. Methods: Balloon angioplasty was attempted in 25 arteries with chronic total occlusion, with the mean time of occlusion of 17±13 months (ranging from 2 to 84 months) and mean length of 14±6 mm (ranging from 5 to 25 mm). The morphology of the lesions included bridging collaterals (4 cases), calcification (3 cases) and major side branch at the lesion (4 cases) . Choice PT?wire was used electively in all the cases. Results: Lesion was crossed successfully in 92% (23/25) cases, without incidences of dissection of the coronary artery with subintimal entry. Balloon angioplasy and stenting (n = 21) were performed with good immediate angiograghic results. Acute myocardial infarction or death occurred in none of the patients. Conclusion Successful recanalization of chronic coronary total occlusions using Choice PTTM wire can be achieved with good safety.     

ChoICE PT导引钢丝在冠脉完全闭塞病变血管重建中的应用

目的观察在慢性完全闭塞病变血管成形术中应用ChoICEPT导入钢丝的效果。方法应用ChoICEPT导入钢丝为25例阻塞时间为(17±13)(2~84)个月、病变长度为(14±6)(5~25)mm的冠状动脉慢性完全闭塞病人行血管成形术。结果手术成功率为92%(23/25)。无1例发生冠状动脉夹层、急性心肌梗死和死亡。经皮冠状动脉血管成形术联合支架的植入获得了良好的即刻血管造影结果。结论在冠脉慢性完全闭塞病变血管成形术中应用ChoICEPT导入钢丝可获得较好的安全性,但其远期疗效仍有待进一步研究。
