LIPV | PV dorsal-caudal comparing to dorsal-cranial orientation (HR 3.447, 95% CI 1.180 to 10.070, p=0.024).10 PV ventral-caudal to dorsal-cranial orientation (HR 3.391, 95% CI 1.088 to 10.571, p=0.035).10
|
RSPV | RSPV diameter: 21.6±2.8 mm at AF recurrence group vs 15.8±2.1 mm at no AF recurrence group (p<0.001).11
|
RIPV | RIPV‐TS frontal angle (°): 45±17° at persistent RIPV isolation group vs 30±14° at RIPV reconnection group.12
|
A score for predicting unfavourable left atrium and PV anatomy | Score consists of RSPV ovality index >1.32, LSPV ovality index >1.2, RSPV antral circumference >69.1 mm, RIPV antral circumference >61.38 mm, RSPV >22.7°, LA diameter and right middle PV.13 Score of ≥4 predicted needs for longer cryoenergy ablation.13
|
No association between anatomy and AF recurrence | No relationship with anatomy (PV ovality, the presence of anatomical variants (right middle PVs, common ostia), shared carina nor carina width).14.
