Derived from more than 1000 procedures the long wire technique has proven to facilitate coronary angioplasty. Maneuvering of the wire is unhindered because the wire is introduced without balloon catheter. Optimal contrast display is possible during crossing of the stenosis. Precision and safety of the procedure is therefore considerably improved. Balloon catheters can be exchanged without recrossing the stenosis including super low profile catheters of small diameter. In case of acute coronary occlusion occurring during angioplasty the long wire allows reintroduction of catheters without danger of via falsa. If necessary a 4.5 f perfusion catheter can be introduced and coronary perfusion with 60-100 ml per minute blood from the femoral artery can be performed by hand. In contrast to the monorail technique the ability to measure pressures through the balloon catheter including intracoronary gradients and coronary capillary pressure is preserved.
长钢丝技术源于1000多次手术，已被证明有助于冠状动脉血管成形术。由于钢丝是在没有球囊导管的情况下插入的，因此钢丝的操作不受阻碍。在穿过狭窄部位时可以实现最佳的造影剂显影。因此，该手术的精确性和安全性得到了显著提高。球囊导管可以在不再次穿过狭窄部位的情况下进行更换，包括超小直径的超薄型导管。在血管成形术期间发生急性冠状动脉闭塞的情况下，长钢丝允许在无经假腔风险的情况下重新插入导管。如有必要，可插入一根4.5F的灌注导管，并通过手动操作从股动脉以每分钟60-100毫升的速度进行冠状动脉灌注。与单轨技术不同的是，通过球囊导管测量压力的能力得以保留，包括冠状动脉内梯度和冠状动脉毛细血管压力。
