Abstract:
Objective To evaluate the potential benefits of placing intra-aortic vacant guide wire on interventional treatment of aorto-ostial lesions. Methods A total of 86 consecutive patients underwent percutaneous coronary interventions (PCI) for aorto-ostial lesions were randomly divided into conventional treatment group ( group A) and intra-aortic vacant guide wire group ( group B). Standard PCI techniques were applied in group A and an intro-aortic vacant guide wire was placed outside the guiding catheter before the guiding catheter into the target coronary artery in group B on basis of standard PCI techniques. The number of guiding catheter, guide wire, X-ray exposure time, total PCI time, the incidence of pressure drop and malignant arrhythmia, contrast agent dose and the number of failure cases were compared between the two groups. Results The number of used guide wire was similar between the groups (2. 0 ± 1. 1 vs. 2. 2 ±0.4, P>0. 05) and the number of guiding catheter used was significantly more in group A than in group B (2. 3 ± 1. 1 vs. 1.3±0. 5, P <0. 01 ). The X-ray exposure time ( 18. 8 min ±6. 9 min vs. 14. 2 min ±5.7min, P< 0.01) was significantly less in groups B and the total PCI time (31.2 min ±8. 1 min vs. 20. 1min ± 4. 5 min, P < 0. 0 1 ) and the amount of contrast agent ( 193.5 ml ± 25.4 ml vs. 130. 6 ml ± 32. 8 ml,P <0. 01 ) and the frequency of pressure drop ( 19 cases vs. 2 cases, P <0. 01 ) were all significantly higher in group A than in group B. Incidence of malignant ventricular arrhythmia (8 vs. 0) and procedure failure (6 vs. 0) was also higher in group A compared to group B. Conclusion The method of using Intra-aortic vacant guide wire is associated with reduced risk and improved success rate of PCI for aorto-ostial lesions.
