Heart failure and atrial fibrillation surgery covers the spectrum of heart failure, perioperative management, and surgical treatment of atrial fibrillation. Standard Maze IV procedure has been launched since 2003 and achieved desired clinical results during followup. The heart failure and atrial fibrillation surgical department was established last year in order to highlight the specific surgical treatment. The heart failure surgery focuses on treaments of heart failure by valve repair, valve replacement, left ventricular restoration, coronary artery bypass grafting, and even heart transplantation. The atrial fibrillation surgery aims refractory atrial fibrillation, especially those with more than two consecutive medical ablation failures, long-term persistent atrial fibrillation, large left atrial diameter, and inability to tolerate anticoagulant therapy. Combining medical electrophysiological examination, all kinds of treatments such as extracorporeal circulation support, minimally invasive thoracoscopic assistance, and simultaneous or sequential surgical hybridization therapy are available. Foundation of the Heart Failure and Atrial Fibrillation surgical department is desire to achieve more efficient clinical management, low rehabitation rate and fewer complications for certain diseases.
