Immediate and mid-term results of the Ross and Ozaki procedures in adults

Objective. To compare the immediate and mid-term results of the AVNeo and Ross procedures for aortic valve disease in adults. Material and methods. After PSM, we distinguished 2 groups by 30 patients: group I — the AVNeo procedure (n=30), group II (n=30) — the Ross procedure. Inclusion criteria: patients aged ≥16 years who underwent the Ross or AVNeo surgery. There were no exclusion criteria. The median follow-up period was 27 [13; 76] months (24 [17; 32] and 80 [33; 103], respectively). Results. Demographic and preoperative clinical and echocardiographic characteristics after PSM did not differ between groups. Mean age of patients was 48 [37; 59] and 50 [42; 54] years, respectively (p=0.707). Surgery time was similar (220 vs 235 min, p=0.705). Cardiopulmonary bypass and myocardial ischemia time was significantly shorter after the AVNeo procedure (108 vs 148 min, p<0.001; 82 vs 115 min, p<0.001, respectively). In-hospital mortality did not differ significantly (3.3% (n=1) and 0, p=0.356). There were no differences in postoperative complications: resternotomy for bleeding (3.3% vs 0, p=1), implantation of permanent pacemaker (0 vs 3.3%, p=0.356), stroke (0 vs 3.3%, p=0.807). Sepsis, AKI and wound superficial infection were not observed in any patient. Three-year overall survival was lower in the AVNeo group (89.4% vs 100%, p=0.015). Three-year freedom from redo surgery was lower in the AVNeo group (79.7% vs 100%, p=0.034). Conclusion. In-hospital mortality and postoperative complications did not differ between groups. Overall 3-year survival and freedom from redo surgery were higher after the Ross procedure.
