Cox-Maze IV in Total Anomalous Pulmonary Venous Drainage After Sutureless Repair.

Modifications of conventional ablation strategies can make arrhythmia surgery more efficient after primary sutureless repair of total anomalous pulmonary venous drainage. We present a surgical technique performed in a 3-year-old patient who experienced ongoing atrial arrhythmia after sutureless repair. A new modified Cox-Maze IV procedure was performed, which respects the special characteristics of patients after sutureless repairs, showing good short-term results.
