The New York Heart Association (NYHA) classification, which assesses the severity of heart failure (HF), is a key factor influencing TAVR outcomes. However, its impact on procedural success, complications, and outcomes remains underrepresented in recent studies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In this multicenter study, data from 2,256 patients who underwent TAVR between 2017 and 2022 at two high-volume German Heart Centers were analyzed. Demographics, comorbidities, and peri-procedural parameters were evaluated to determine the influence of pre-procedural NYHA classification on complications, hospital stay, and outcomes. Multivariable logistic regression analyses were performed to assess the independent prognostic impact of pre-procedural NYHA class on 30-day and 1-year mortality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      NYHA class III\/IV prior to the procedure was associated with higher peri-procedural complication rates, prolonged hospital stays, and increased mortality compared to class NYHA I\/II.
