Balloon aortic valvuloplasty as a palliative treatment in patients with severe aortic stenosis and limited life expectancy: a single center experience

Figure 4. Mirror period for the evaluation of days of heart failure hospitalization. The figure is describing the method to assess the number of days of hospitalization before/after BAV. Patients 1 and 2 died before 1-year post BAV, thus the time period used to record the number of days of HF hospitalization was less than 1 year in these patients. Patient 3 survived more than 1 year, thus the entire year before BAV was used to collect number of days of HF hospitalization.
