Figure 3. Analysis of LET during CBA.
A: Percentage of patients in whom LET reached 15°C during CBA.
B: LA roof height from the point where the LAPW and esophagus make
contact were compared between patients in whom LET reached 15°C during
CBA of the LA roof (Group A) and others (Group B).
C: The distance between the LA roof and esophagus was compared between
Groups A and B.
The analysis described in Panels B and C was performed in patients in
whom the esophagus passed the posterior of the LA roof (46 patients,
including six with GH).
CBA, cryoballoon ablation; GH, gastric hypomotility; LA, left atrial;
LAPW, left atrial posterior wall; LET, luminal esophageal temperature;
LIPV, left inferior pulmonary vein; RIPV, right inferior pulmonary vein.
