Voltage-based electroanatomic mapping system for MR-guided cardiac electrophysiology: preliminary swine validations
Background MRI produces images that serve as luminal, edema, & scar maps to assist in the Electrophysiological (EP) treatment of ventricular and atrial arrhythmias [1]. Until MR-compatible EP devices are widely available, there will be a need to perform EP partially in the MRI for imaging, and partially outside the MRI for ablation, puncture & navigation. An MR-conditional voltage-based Electro...
متن کاملMRI-compatible voltage-based electroanatomic mapping system for 3T MR-guided cardiac electrophysiology: swine validations
Background MRI provides luminal, edema, & scar images which assist in the Electrophysiological (EP) treatment of ventricular and atrial arrhythmias]. Until a complete set of MR-compatible EP-devices is available, patients must be repeatedly moved between the MRI, where imaging and mapping occur, to the conventional EP suite, where puncture, navigation and Radio-Frequency Ablation occur. MRI-con...

متن کاملCardiac resynchronization therapy device implantation guided by electroanatomic mapping system when contrast medium infusion is contraindicated
Introduction The implantation of transvenous leads for pacemakers and defibrillators is traditionally performed using fluoroscopic guidance. When cardiac resynchronization therapy (CRT) is indicated, iodine contrast medium (ICM) infusion for coronary sinus (CS) branch visualization is also needed. Adverse reactions to ICM during cardiac catheterization and coronary interventions are common. Chr...
متن کاملVURTIGO: Visualization Platform for Real-Time, MRI-Guided Cardiac Electroanatomic Mapping
Guidance of electrophysiological (EP) procedures by magnetic resonance imaging (MRI) has significant advantages over x-ray fluoroscopy. Display of electroanatomic mapping (EAM) during an intervention fused with a prior MR volume and DE-MRI derived tissue classification should improve the accuracy of cardiac resynchronization therapy (CRT) for ventricular arrhythmias. Improved accuracy in the sp...
