Risk factors analysis on failure of maze procedure: mid-term results☆

Abstract: The results of our maze procedure during the last decade showed an acceptable success rate and the patients who were restored to sinus rhythm after maze procedures showed better long-term survival rates. For the patients who have independent biological risk factors, more thorough ablation lesion set is recommended for better long-term results.

“…The impact of the Maze procedure without mitral valve surgery at discharge was calculated by multivariate logistic regression analysis, adjusting for established predictors included left atrial diameter (LAD), left ventricular ejection fraction and age. [10][11][12] Freedom from AF was estimated using the Kaplan-Meier survival method and compared with a log-rank test. Furthermore, multivariate Cox proportional-hazard analyses were performed to calculate adjusted hazard ratios between groups.…”

“…Some authors have established the cutoff values of LAD as 50 mm or 60 mm, roughly, to determine the prediction of AF recurrence. 13,14 However, we derived the optimal cutoff value from the statistically warranted ROC curve. This value will be utilized when the patient is not tolerant of a longer aortic cross-clamp time or has lower amplitude of F-wave in V1, which was also a signifi cant predictor in univariate analysis for the late-term recurrence of AF.…”

“…Необходимо отметить, что эффективность метода РЧА как сохранение стабильного синусового ритма или отсутствие рецидивов ФП значительно варьирует, и это зависит от множества различных факторов, в том числе, от характера аритмии (пароксизмальная, персистирую-щая и постоянная) и модификаций операции Maze [5][6][7][8][11][12][13]. Также показано, что эффективность РЧА по поводу пароксизмальной формы ФП при продолжи-тельных наблюдениях постепенно снижается и в период от 1 года до 5 лет составляет 69-57% [5,6,10,11].…”

“…В России этому также способствовало расширение сети федераль-ных учреждений по оказанию высокотехнологичных видов медицинской помощи населению. Наиболее часто применяется радиочастотная аблация (РЧА) аритмогенных зон в виде различных модификаций операции Cox-Maze, эффективность которой у боль-ных с пароксизмальной ФП варьирует от 45 до 95% [5][6][7][8]. Физиологическое обоснование проведения РЧА и ее высокая антиаритмическая эффективность у больных с ФП связаны с установлением эктопиче-ских фокусов в области устьев легочных вен до 80-90% случаев [2,5,9].…”
