... There were 74 patients (mean age 74±10 years, ejection fraction [FE]: 30.07%±4 .5, Euroscore: 6.6±2.9). Results: Hospital mortality was 9.5%, with a follow up time of 59.2 ± 36 months. The survival rate at 10 years was 57%. There was also an improvement in their clinical symptoms and echocardiographic parameters (postoperative FE: 40.36%±11.2). Conclusion: In this group of patients with high operative risk, the long-term results of several studies demonstrate the superiority of surgical treatment on medical treatment.
