Fig. 3From: Successful case of complex atrial flutter occurring in a patient with congenitally corrected transposition of the great arteries, aberrant left atrial appendage, and situs inversusThe first ablation line. a The first ablation line was performed from 12’ clock of tricuspid annulus to right superior pulmonary vein (RSPV). During ablation of this line, CL of atrial flutter prolonged from 260 to 275 ms. b CL of atrial flutter increased to 290 ms but tachycardia did not terminate when the first ablation line accomplishedBack to article page
