Impact of Atrial Fibrillation on Outcomes of Aortic Valve Implantation
Section snippets
Methods
The study was conducted using the National Inpatient Sample (NIS) of the Healthcare Cost and Utilization Project (HCUP) data set between 2011 and 2017.14 The population selected from the NIS data set for this study were patients with AS, with and without AF, undergoing TAVI or SAVR between 2011 and 2017. These data include male and female patients >18 years of age. These timeframes were chosen to allow a sufficient run-in period for adoption of TAVI throughout the United States, as well as the
Results
A total of 742,168 patients had AS of which 645,909 patients met the exclusion criteria (Figure 1). Overall, the median (IQR) age of patients was 74 (66 to 81) years, and 62.1% (59,730 patients) were male. The most prevalent comorbidity was hypertension (65.5%; Table 1). In-hospital mortality for the complete cohort was 2.5%. The median (IQR) value of LOS and adjusted healthcare associated costs (HCAC) in the analyzed cohort were 6 (4 to 10) days and $44,299 ($34,006-59,585), respectively.
SAVR
Discussion
This study is a real-world analysis of the LOS, Healthcare associated costs, and in-hospital mortality in patients undergoing interventional procedures for significant AS. The key findings are as follows: (1) the co-existence or development of AF leads to a significantly higher inpatient LOS and Healthcare associated costs in patients undergoing both SAVR and TAVI; (2) when adjusted for all other variables, AF was not associated with increased in-hospital mortality; (3) patients undergoing SAVR
