RESUMO
OBJECTIVE: To assess the occurrence of late thromboembolism after surgical repair of chronic atrial fibrillation (AF) simultaneously with repair of mitral valve using the Cox-Maze procedure. METHODS: 69 patients underwent Cox 3 procedure, with no cryoablation simultaneously with mitral valvuloplasty or prosthesis. Mean age was 49.9±13.2 years. Mean follow-up was of 31.7±19 months. Types of lesion were as follows: 33 (48 percent) stenoses, 23 (33 percent) insufficiencies, and 13 (19 percent) double lesions. Procedures were: 64 (93 percent) valvuloplasties, 3 (4 percent) biological and 2 (3 percent) mechanical prosthesis placement. There were 9 (13 percent) patients with previous systemic embolism and 2 (3 percent) had left atrial thrombi. RESULTS: Early mortality was 7 percent and late 1 percent. 2 patients (3 percent) were reoperated for mitral placement. At last evaluation, 10 patients (15 percent), were in AF. The remaining 59 (85 percent) were either in sinus / atrial rythm (74 percent) or under pacing (12 percent). There were no occurrence of early or late, systemic or pulmonary embolism. Permanent anticoagulation was employed in 16 cases, 10 in regular rythm and 6 in AF. The remaining 47 (75 percent), 2 in AF and 45 in regular rythm, did not receive anticoagulants. CONCLUSIONS: These results are in accordance with others series, where the occurrence of embolism was rare after maze procedure. Permanent systemic anticoagulation seems to be unnecessary in those cases
