Radiofrequency ablation of XXXX during mitral valve surgery.

@entity1 @entity64 @entity339 @entity75 @entity956 @entity955 @entity4794
Twenty-three @entity1 underwent endocardial radiofrequency ablation of @entity955 ( @entity955 ) during mitral valve procedures with a previously described left @entity75 pattern. A temperature-controlled 7-coil surgical probe delivered 60-second lesions at 80 degrees C. The left atrial appendage was oversewn after ablation. Ages ranged from 28 to 88 years. Nineteen @entity1 had chronic @entity955 that was present for over 1 year in 74%; 12 @entity1 had @entity4794 . Mean left atrial diameter was 5.4 +/- 0.7 cm. There was 1 operative death unrelated to the ablation, and no @entity64 or ablation-related complications were observed. At mean follow-up of 32.5 weeks, 86% of the 22 survivors were in sinus rhythm. All 18 @entity1 with left atrial diameter <6 cm are in sinus rhythm. All postoperative @entity956 was transient, and no @entity1 required subsequent transcatheter ablation. This lesion pattern is safe and effective when applied in the method described here. It appears to be a reasonable alternative to the complete Maze 3 lesion pattern in @entity1 with @entity339 .
