摘要

OBJECTIVES: To investigate the feasibility of integration of the dual source computed tomography (DSCT) and magnetic navigation system (MNS) to guide percutaneous coronary intervention (PCI). BACKGROUND: MNS has proven to be feasible for yielding high rates of procedural success for PCI. DSCT coronary angiography (DSCT-CA) may provide a roadmap of a target vessel and serve as a reference route for MNS. Combination of these two technologies might decrease the contrast use, fluoroscopy exposure, and be beneficial to the intervention of the totally occluded lesions. METHODS: Twenty-five patients with positive results of DSCT-CA and indications for PCI were included. CT images were transferred to MNS, and target vessels were extracted and registered to X-ray system as a roadmap. RESULTS: DSCT-CA and MNS-assisted PCIs were successfully performed in 25 of the 26 target vessels (96.2%), with the mean guidewire crossing time of 100.0 (25-75% inter-quartile ranges (IQR): 70.7-157.8) sec, mean total radiation dosage of 268.1 (IQR: 150.5-527.0) muGym(2) , or 42.0 (IQR: 23.0-70.0) mGy, respectively. The contrast usage for guidewire positioning was 0 (IQR: 0-3.0) ml for the successfully crossed lesions. Both of the two totally occluded lesions in this study were successfully crossed with guidewires under the guidance of the DSCT-CA derived roadmap. CONCLUSION: Integration of DSCT with MNS for PCI is feasible. This integration of advanced modalities might decrease contrast usage, lower fluoroscopy exposure for guidewire positioning, and might also play a role in totally occluded lesions.
