Abstract

UNLABELLED

An 8 French (F) double loop guiding (DLG) catheter was developed for percutaneous transluminal coronary angioplasty (PTCA) of the right coronary artery (RCA) and tested in 80 patients: primary use in 59 patients, and after failure of an 8 F right Judkins guiding (RJG) catheter in 21 patients. Primary use resulted in stable intubation of RCA in 55 patients (93%), but PTCA was successful in 50 (91%). Five failures resulted from inability to cross or dilate the lesion. After failure of an 8 F RJG in 21 patients, successful stable intubation of RCA with a DLG was achieved in 19 patients (90%), but PTCA was successful in 17 patients (81%). Failure of RJGs in 21 patients resulted from inability to intubate the RCA in 12 patients, or inadequate back up support by the guiding in 9 patients.

CONCLUSION

DLGs increased the success rate of PTCA of the RCA after failure of RJGs.

未标记

一种8法国（F）双环引导（DLG）导管被开发用于右冠状动脉（RCA）的经皮腔内冠状动脉成形术（PTCA），并在80例患者中进行了测试：59例患者为首次使用，21例患者在8F右Judkins引导（RJG）导管失败后使用。首次使用时，55例患者（93%）实现了RCA的稳定插管，但PTCA成功的有50例（91%）。5例失败是由于无法穿过或扩张病变。在21例患者的8F RJG导管失败后，19例患者（90%）使用DLG成功实现了RCA的稳定插管，但PTCA成功的有17例（81%）。21例患者中RJG导管失败的原因是12例患者无法插入RCA，或9例患者引导导管的支撑不足。
