Electroanatomic visualization of coronary arteries: a case series to elicit safety, feasibility, and diagnostic value in complex ablation procedures
Authors' conclusion
We demonstrated the feasibility and safety of CA visualization and integration in an EAM.
Study context
- Population
- Ablation procedures with suspected close proximity of a possible ablation site to an epicardial vessel (VT and premature ventricular contraction ablation)
- Participants
- 9 procedures
- Outcome
- Feasibility, safety and advantages of wire-based live visualization of coronary arteries in an electroanatomic mapping system, and its diagnostic information
Methodological detailssingle-centre, Uncoated-tip guidewire introduced into relevant coronary arteries after exclusion of critical stenosis by coronary angiography, connected to the electroanatomic mapping (EAM) system by clip and pin, Wire insertion and intracoronary mapping by EP specialists, assisted by an interventional cardiologist
