摘要：Atrial fibrillation (AF) is the most common arrhythmia observed in patients with hypertrophic cardiomyopathy (HCM). Development of AF in patients with HCM is associated with worsening of signs and symptoms and progression of heart failure. In this article a case report of successful surgical treatment of HOCM and AF is presented. Preoperative examination was performed according to protocol approved in our clinic: electrocardiography, ECG Holter monitoring, echocardiography, chest X-ray, cardiac MRI with gadolinium enhancement, cardiac CT-angiography, heart catheterization and EP study. After median sternotomy intraoperative epicardial atrial mapping was performed. Surgical procedure included septal myectomy from the right ventricle and epicardial modification of cryo-maze procedure. At discharge there were no episodes of AF according to ECG Holter monitoring data. According to echocardiography LOVT peak gradient was 25 mm Hg.
