Reconstructing left atrium (LA) anatomy for atrial fibrillation (AF) ablation with CARTOSound intracardiac ultrasound (ICE) is usually done from the right heart chambers. However, as visibility of LA structures with this method is frequently suboptimal additional point-by-point or fast anatomical mapping is needed. Therefore, our aim in this case series was to present our experience with transseptal LA imaging with CARTOSound ICE.
After initial imaging and LA anatomy reconstruction from the right heart chambers, LA access with ICE was achieved by navigating the ICE probe along the wire placed through the transseptal puncture or through the long sheath placed transseptally. With the ICE placed transseptally all LA structures relevant to PVI could be imaged in great detail.
We performed PVI in 15 patients with AF (13 paroxysmal, 2 persistent). All PVIs were successfully achieved with irrigated contact-force sensing catheter. Median procedure time was 150 min (interquartile range: 130 - 160 min) without the use of fluoroscopy.
Transseptal CARTOSound imaging allowed us to make the relevant anatomy for succesfull PVI without flouroscopy or additional contact mapping.
