Transatrial pericardial insufflation of carbon dioxide to facilitate epicardial mapping and ablation of atrial and ventricular arrhythmias
Authors' conclusion
TAPI-CO2 is a feasible, efficient, and relatively safe technique for facilitating EA. It provides a simplified alternative to CO2 insufflation through the coronary sinus. Further studies are needed to confirm these results and to identify the populations of patients that would benefit most from this technique.
