| description | Computed tomography coronary angiography (CTCA) has been successfully integrated with the magnetic navigation system (MNS) to facilitate a roadmap-assisted percutaneous coronary intervention (PCI). The aim of this study was to compare this new approach of PCI versus conventional PCI regarding the difference of contrast usage, x-ray exposure, procedure success, and in-hospital expenses.
Thirty-eight patients with stable coronary artery disease and coronary artery lesions of ≥70% diameter stenosis diagnosed by both pre-procedure CTCA and coronary angiography (CAG) were enrolled to receive the MNS and CT roadmap-assisted PCI. Another 38 patients were consecutively recruited to receive conventional PCI, matched with the MNS group by the vessel and lesion type base on American College of Cardiology/American Heart Association criteria.
Regarding the process of the guidewire placement, wherein the technical difference of the two procedures exists, the median contrast usage for guidewire crossing was significantly lower in the MNS group than in the conventional group [0.0 mL (interquartile range [IQR], 0.0-3.0 mL) vs 5.0 mL (IQR, 3.1-6.8 mL); P |

There were no significant differences between the two groups concerning the total contrast usage, total radiation dosage of the PCI, the procedural fees, or the overall in-hospital expenses. All of the enrolled vessels were successfully intervened in both groups.
In PCI of simple lesions, the application of CT guidance and magnetic navigation had modest impacts on radiation dosage and contrast usage for wire crossing, but no impact on overall radiation dosage or contrast usage for the procedure. In addition, the use of CT roadmap and MNS was likely more expensive compared to PCI using conventional radiographic technique.</description><identifier>EISSN: 1557-2501</identifier><identifier>PMID: 23549490</identifier><language>eng</language><publisher>United States</publisher><subject>Aged ; Contrast Media ; Coronary Artery Disease - economics ; Coronary Artery Disease - therapy ; Female ; Hospital Costs ; Humans ; Magnetics - economics ; Magnetics - methods ; Male ; Middle Aged ; Percutaneous Coronary Intervention - economics ; Percutaneous Coronary Intervention - methods ; Radiation Dosage ; Retrospective Studies ; Tomography, X-Ray Computed - economics ; Tomography, X-Ray Computed - methods ; Treatment Outcome</subject><ispartof>The Journal of invasive cardiology, 2013-04, Vol.25 (4), p.177-181</ispartof><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/23549490$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Hao, Ruina</creatorcontrib><creatorcontrib>Zhang, Qiu</creatorcontrib><creatorcontrib>Xu, Zhuowen</creatorcontrib><creatorcontrib>Tang, Lijun</creatorcontrib><creatorcontrib>Yang, Zhijian</creatorcontrib><creatorcontrib>Cao, Kejiang</creatorcontrib><creatorcontrib>Li, Chunjian</creatorcontrib><title>Magnetic navigation system and CT roadmap-assisted percutaneous coronary intervention: a comparison to the conventional approach</title><title>The Journal of invasive cardiology</title><addtitle>J Invasive Cardiol</addtitle><description>Computed tomography coronary angiography (CTCA) has been successfully integrated with the magnetic navigation system (MNS) to facilitate a roadmap-assisted percutaneous coronary intervention (PCI).
