    Abstract:
    OBJECTIVES: We aimed to evaluate sex-related differences in short-term and long-term outcomes of patients undergoing balloon aortic valvuloplasty (BAV) for severe aortic stenosis (AS). METHODS: A total of 112 patients with severe AS underwent 114 BAV procedures as palliative procedure, bridge to definitive treatment, or before urgent non-cardiac surgery. Patients were followed for 24 months. RESULTS: Of the 112 patients, 70 (62.5%) were women. Women were older, and had a higher STS score and higher prevalence of chronic kidney disease and arterial hypertension. Indications for BAV did not differ by gender. Women had a higher risk of vascular complications than men (15.7% vs 0.0%; P=.01), but with a similar rate of major periprocedural complications (17.1% vs 9.5%; P=.40). Transcatheter aortic valve implantation (TAVI) was performed in 22.8% of women and 26.2% of men (P=.61) and surgical aortic valve replacement in 10% of women and 11.9% of men (P=.70). Women and men treated finally with TAVI/aortic valve replacement had lower mortality as compared with conservative treatment (P<.01). No difference in in-hospital and 24-month mortality between women and men was observed (11.4% vs 4.9% [P=.26]; 63.3% vs 39.0% [P=.22], respectively). In a multivariable Cox model, STS score above 9.8% (hazard ratio, 2.29; 95% confidence interval, 1.09-4.83; P=.03) was an independent predictor of all-cause death only in women. CONCLUSION: Despite the presence of sex-related differences in baseline and procedural characteristics as well as in the risk of vascular complications, no difference in major procedural complications and long-term mortality was confirmed for patients with severe AS undergoing BAV.
