Percentage of durable lesions confirmed at the beginning of the redo
ablation procedure.
The analysis of PV durability was performed in 42 patients including
three patients with an LCPV who underwent redo ablation procedures. PV
recurrence was confirmed in 4, 4, 9, and 11 patients at the LSPV, LIPV,
RSPV, and RIPV, respectively. The durability of the LA roof line, LAPW
bottom line, and CTI line was analyzed in patients who had obtained
complete conduction block in the index ablation procedure (25 patients
for the LA roof line, 21 patients for the LAPW bottom line, and 37
patients for the CTI line). CTI,
cavotricuspid isthmus; LA, left atrial; LAPW, left atrial posterior
wall; LCPV, left common pulmonary vein; LIPV, left inferior pulmonary
vein; LSPV, left superior pulmonary vein; PV, pulmonary vein; RIPV,
right inferior pulmonary vein; RSPV, right superior pulmonary vein.
