“…Bentall is more popular than the AVS because its learning curve is less steep rendering it more reproducible. The use of AVS, however, has expanded in the last years due to encouraging reported results (28,29) and has been embraced with enthusiasm. Specialized centers report reduced cardiac mortality and valve-related morbid event rates for AVS when compared with composite valve graft surgery (30).…”

Background: We retrospectively reviewed our experience with the modified Bentall procedure and evaluated the short-and long-term results over a period of 18 years. Methods: Between 1999 and 2017, 89 patients with a mean age of 57.3±13.9 years underwent the modified Bentall operation with a slight modification for the correction of aortic root disease.Results: The operative mortality was 1.1% while the overall early mortality rate, defined as death within 30 days of initial hospitalization, was 2.2% (2/89). Logistic regression analysis revealed that increased Euroscore and aortic cross-clamp times were associated with greater likelihood for complications. The overall survival rates for the 89 patients (including deaths occurred at the initial hospitalization) were 93.0% (SE =3.0%) at 6 months, 93.0% (SE =3.0%) at 1 year, 89% (SE =5.0%) at 5 years and 73.0% (SE =5.0%) at 10, 15 and 18 years. Multiple Cox regression analysis for survival identified that increased aortic crossclamp time, increased age, having a concomitant cardiac procedure and increased NYHA Class were associated with greater hazard. Left ventricular remodeling was assessed by means of echocardiography preoperatively and 1, 3, 6 and 12 months postoperatively. Conclusions: According to our experience, the Bentall procedure is a safe procedure, provides optimal long-term survival and can still be regarded as the gold standard procedure for aortic root replacement.

BACKGROUND: Aortic stenosis (AS) itself is a common disease in patients of older populations, and its combination with a narrow aortic root puts the surgeon in front of choosing the most optimal option. The advantages of Ozaki's operation include hemodynamics close to the native aortic valve (AV) and the absence of the need for lifelong anticoagulant therapy. AIM: To evaluate the hospital and long-term results of surgical treatment of patients with AS and a narrow fibrous ring who underwent Ozaki surgery or AV prosthetics with a biological prosthesis. MATERIALS AND METHODS: In total, 836 isolated Ozaki operations or combined interventions of this kind were performed at the Federal Center for Cardiovascular Surgery (Penza). This retrospective single-center study included 150 patients with critical AC (effective opening area ≤1 cm2) in whose surgical treatment tactics Ozaki surgery or prosthetics with a biological prosthesis were used. RESULTS: In the early postoperative period, group 1 patients had significantly lower values of the average and maximum gradients on the aortic valve and a larger area of the effective opening of the aortic valve. Also, in group 1 patients, the postoperative period of stay in intensive care is significantly higher, which is a consequence of the longer duration of the operation, the time of artificial circulation and myocardial ischemia. Long-term mortality is higher in the group with prosthetics of AV (Log Rank=0.006). Freedom from re-operation according to the analysis, there was no significant difference between the groups (Log Rank=0.226). CONCLUSION: Ozaki surgery demonstrates the best hemodynamic characteristics on AV in comparison with a biological prosthesis in patients with a narrow fibrous ring of AV in the early and long-term follow-up periods.
