To evaluate the results obtained in coronary angioplasty using the new very low profile monorail catheter.
A retrospective study to define the causes and frequency of successful and unsuccessful coronary angioplasty on proximal and distal lesions located in the three coronary vessels.
Patients referred to the Hemodynamic Unit for coronary angioplasty.
Coronary angioplasty was performed in 106 patients with cardiac ischemic disease (stable angina, unstable angina and myocardial infarction after thrombolytic therapy).
To perform coronary angioplasty using a monorail system, including dilatation of vessels (angioplasty) and to measure the intracoronary gradient.
A high success rate was achieved (92%) independent of vessel dilated or of the position of the stenosis. There was a lower success rate in complex lesions.
In this study, this newly modified system for coronary angioplasty with balloon catheter and monorail pressure catheter gave a very high performance.
评估使用新型超薄壁单轨导管进行冠状动脉血管成形术的效果。
一项回顾性研究，以确定位于三支冠状动脉的近端和远端病变进行冠状动脉血管成形术成功与失败的原因及频率。
被转至血流动力学科进行冠状动脉血管成形术的患者。
对106例心脏缺血性疾病（稳定型心绞痛、不稳定型心绞痛和溶栓治疗后的心肌梗死）患者进行了冠状动脉血管成形术。
使用单轨系统进行冠状动脉血管成形术，包括血管扩张（血管成形术）并测量冠状动脉内压力阶差。
无论扩张的血管或狭窄部位如何，均取得了较高的成功率（92%）。复杂病变的成功率较低。
在本研究中，这种新改良的使用球囊导管和单轨压力导管的冠状动脉血管成形术系统表现出非常高的性能。
