Abstract

Introduction: The Maze procedure using the unipolar radiofrequency devices is an efficient method for atrial fibrillation (AF) in patients undergoing mitral valve surgery : Combined retrospective and prospecctive study; 50 patients who had the mitral valve disease with AF were performed the mitral valve surgeries and/or tricuspid valve repair, left atrial reduction and the Maze procedure using the unipolar radiofrequency devices. Open or minimally invasive surgery Result: Mean age: 53,44± 10,05; 90 % persistent AF and 10 % paroxysmal AF. The left atrial diameter before surgery and at discharge: 53,65±8,22 and 42,71±6,58 mm. Open surgery 84 % and minimally invasive surgery 16 %. Mitral valve replacement 84 %, mitral valve repair 16 %. Duration of cross-clamp aorta 98,68±20 minutes. Duration of cardiopulmonary bypass 140,18±41,04 minutes. The rates of free from AF and sinus recovery after surgery immediately, at discharge, 3 months, 6 months were 86 and 64 %; 94 and 84 %; 94 and 92 %; 94 and 89,2 %. 1 patient had the pacemaker after 3 months. Postoperative complications: Re-operative hemorrhage (2 %), renal failure (2 %), wound infection (2 %) Conclusion: The Maze procedure using the unipolar radiofrequency devices had a positive early result.
