4.2 Study limitations
Our study findings should be interpreted in light of our study
limitations, the first of which is its execution as a study involving a
fairly small number of patients. Second, the recorded bipolar voltages
might have been affected by various factors, such as catheter
orientation, contact force, electrode area, and interelectrode spacing.
We note, however, that the best performing currently available mapping
catheter was used. Third, gaps might have been caused by various other
factors, such as the catheter contact angle, circulating blood flow, and
trabecula in the LA. All of these factors need to be considered to
ensure lesion durability.
