Modified Maze Procedure for Atrial Fibrillation as an Adjunct to Elective Cardiac Surgery: Predictors of Mid-Term Recurrence and Echocardiographic Follow-Up

The radiofrequency maze procedure achieves sinus rhythm in 45%-95% of patients treated for atrial fibrillation. This retrospective study evaluates mid-term results of the radiofrequency maze-performed concomitant to elective cardiac surgery-to determine sinus-rhythm predictive factors, and describes the evolution of patients' echocardiographic variables.
