Background:Magnetic navigation system (MNS) allows calculation of the vessel coordinates in real space within the patient's chest for percutaneous coronary intervention (PCI). However, its impact on the procedural parameters and clinical outcomes is still a matter of debate. To derive a more precise estimation of the relationship, a meta-analysis was performed.Methods and Results:Studies exploring the advantages of MNS were identified in English-language articles by search of Medline, Web of Science, and Cochrane Library Databases (inception to October 2015). A standardized protocol was used to extract details on study design, region origin, demographic data, lesion type, and clinical outcomes. The main outcome measures were contrast consumption, procedural success rate, contrast used for wire crossing, procedure time to cross the lesions, and the fluoroscopy time fluoroscopy time. A total of 12 clinical trials involving 2174 patients were included for analysis (902 patients in the magnetic PCI group and 1272 in the conventional PCI group). Overall, contrast consumption was decreased by 40.45 mL (95% confidence interval [CI] −70.98 to −9.92, P = 0.009) in magnetic PCI group compared with control group. In addition, magnetic PCI was associated with significantly decreasing procedural time by 2.17 minutes (95% CI −3.91 to −0.44, P = 0.01) and the total fluoroscopy time was significantly decreased by 1.43 minutes (95% CI −2.29 to −0.57, P = 0.001) in magnetic PCI group. However, procedural success rate, contrast used for wire crossing, procedure time to cross the lesions, and the fluoroscopy time to cross the lesions demonstrated that no statistically difference was observed between 2 groups.Conclusion:The present meta-analysis indicated an improvement of overall contrast consumption, total procedural time, and fluoroscopy time in magnetic PCI group. However, no significant advantages were observed associated with procedural success rate.

Comparison of magnetic wire navigation with the conventional wire technique for percutaneous coronary intervention of chronic total occlusions: a randomised, controlled study

Wire crossing of a chronic total coronary occlusion (CTO) is time consuming and limited by the amount of contrast agent and time of radiation exposure. Magnetic wire navigation (MWN) might accelerate wire crossing by maintaining a coaxial vessel orientation. This study compares MWN with the conventional approach for recanalization of CTOs. Forty symptomatic patients with CTO were randomised to MWN (n = 20) or conventional approach (n = 20) for antegrade crossing of the occlusion. In the intention-to-treat analysis, MWN showed a shorter crossing time (412 versus 1131 s; p = 0.001), and, consequently, lower usage of contrast agent (primary endpoint 42 versus 116 ml; p = 0.01), and lower radiation exposure (dose-area product: 29 versus 80 Gy*cm(2); p = 0.002) during wire crossing compared to the conventional approach. Accordingly, in the per-protocol analysis, the wire-crossing rate was, in trend, higher using the conventional approach (17 of 31) compared to MWN (9 of 28; p = 0.08). The use of MWN for revascularisation of CTOs is feasible and reduces crossing time, use of contrast agent, and radiation exposure. However, due to a broader selection of wires, the conventional approach enables wire crossing in cases failed by MWN and seems to be the more successful choice.

Initial Experience with a Magnetic Navigation System for Invasive Treatment in Patients with Non-ST-Segment Elevation Acute Coronary Syndromes

Abstract: MNS assisted technique appears to be feasible and effective in NSTE-ACS patients with more complex lesions; however, it probably offers little benefit in simple lesions like ACC/AHA type A/B1.
