24 consecutive patients (mean age 68.6±6.1 years, 58% men) underwent
redo procedure after previous successful EIVM for persistent AF (n=21;
88%) or PMLAF (n=5; 21%). In each case, EIVM had an acute effect, with
a post-EIVM scar in the VOM (median 12.4 cm2[interquartile range (IQR) 7.6–15.7]). MI bidirectional block was
obtained in 20/24 patients (83%). In each patient, the EIVM-related
lesion persisted, with a chronic scar in the VOM region (median 13.1
cm2 [IQR 8.1–15.9]). One quarter of patients
(5/20) had late MI reconnection, which was located at the mitral annulus
edge or in the coronary sinus.
