摘要
Purpose: Left atrial calcification (LAC) is found in long-lasting rheumatic valvular disease and is almost always accompanied by atrial fibrillation (AF). In the presence of LAC, endoatriectomy is required when performing the maze procedure. However, the technical feasibility of endoatriectomy and the long-term outcomes of the maze procedure in patients with LAC are uncertain.Methods: The medical records of 18 consecutive patients who underwent combined endoatriectomy and maze procedure were analyzed retrospectively.Results: Accompanying operations were mitral valve replacement (n = 16) and commissurotomy (n = 2). There was 1 operative death from sepsis following mediastinitis. When patients were divided into "broad" (n = 11) and "limited" (n = 7) groups, with the extent of LAC either greater or less than half of the left atrium, respectively, there was no intergroup difference in postoperative complications. During follow-up (median, 11.4 years), AF recurred in 11 patients. At the last follow-up visits, electrocardiography revealed significantly fewer patients in the broad group maintaining sinus rhythm (1/11 vs 4/6, P = 0.03). The 10-year AF recurrence-free survival rates were 13.9% and 66.7% in the broad and limited groups, respectively (P = 0.01). Conclusions: The maze procedure combined with endoatriectomy seems technically feasible with acceptable long-term rhythm outcomes if the LAC extent is limited.
