Feasibility and safety of three-dimensional electroanatomical cardiac mapping, mapping-guided biopsy and transseptal puncture in dogs

Successful high-resolution three-dimensional electroanatomical mapping and radiofrequency catheter ablation of a posteroseptal accessory pathway in a dog using CARTO 3

“…Right and left atrial 3D EAM was performed under anaesthesia as described earlier [1]. After anaesthesia supraventricular tachycardia occurred spontaneously and was inducible by burst pacing from the coronary sinus (CS 9-10).…”

Three-dimensional electroanatomical mapping for guidance of pulmonary vein isolation as treatment for persistent atrial fibrillation in a dog

“…Pre-anaesthetic bloodwork (biochemistry and haematology) including cardiac Troponin I i (cTnI) (0.02 ng/mL; reference < 0.06 ng/mL) was normal. A cardiac computed tomography (CT) scan j was performed as described earlier [1]. Mapping was done under general anaesthesia using the CARTO 3 System k .…”

“…Patient positioning and preparation was performed as previously described [1] and is shown in Supplemental allows both surfaces to be viewed even when fully merged. An anatomical right atrial map (561 points) was generated using a Pentaray p mapping catheter.…”

“…Subsequently, a 6 Fr coronary sinus catheter p was placed (jugular approach) to serve as a timing reference. Transseptal puncture was performed as described earlier [1]. Next, a bipolar voltage map of the left atrium and the ostia and distal part of the pulmonary veins (3472 points) was created during AF using the Pentaray (Fig.…”
