Magnetic-guided percutaneous coronary intervention enabled by two-dimensional guidewire steering and three-dimensional virtual angioscopy: initial experiences in daily clinical practice

摘要: Aims:Percutaneous coronary intervention (PCI) has been broadly established and often includes highly complex stenoses that require difficult navigation. The purpose of this study is to assess the feasibility a new magnetic navigation system (MNS) enable intracoronary guidewire deployment PCI in daily clinical practice compare 2D guidance virtual 3D angioscopy feature. Methods Results:We included 30 consecutive patients (pt) whom 36 arteries were targets. Patients randomized steering by either or (33%). In 31/36 (86%) interventions MNS successfully passed culprit stenosis procedure was accomplished PCI. In 5/30 pt an multivessel performed. Three 5 unsuccessful procedures failed due recanalization subtotal chronic occlusion including 1 who required surgical intervention. 2/36 guided performed effectively after prior conventional failure related anatomy. contrast medium amount needed position 60 ± 101 mL vs. 14 15 (p < 0.05). 3 did not harm implanted pacemaker defibrillator system. Conclusion:Magnetic useful selected patients. our experience, success less likely evidence occlusion.
