65Utilization of percutaneous left atrial appendage closure in patients with atrial fibrillation in the United States: analysis from national inpatient sample 2016
Abstract Introduction/Background In recent years, the percutaneous left atrial appendage closure (LAAC) has been gaining its popularity in the US. However its use in the US in recent years has not been well described. Purpose To provide an updated cross-sectional survey of performance of percutaneous LAAC in the US at national database level. Methods We use ICD-10 disease and procedure code to identify all the percutaneous LAAC performed in 2016 in US from national inpatient sample database. The demographic feature, comorbidity, mean time to procedure, mortality, complication rate, length of stay, total cost were described. Procedure related complication Including any vascular, cardiac, respiratory, neurologic and renal complications defined by AHRQ as patient safety indicators. Results There is approximately a total of 7550 percutaneous LAAC performed in the US in 2016. The majority of the patients were elderly (mean age 66.83±0.34), white (80.41%) male (59.04%). The mean Charlson Comorbidity Index score is 1.74, with hypertension (76.75%), diabetes (29.23%) being the most common comorbidity. The mean time to procedure is 1.98±0.11 days. The procedure related mortality is 2.06%, whereas the complication rate is 19.6%. The average length of stay is 10.77 day, with an average total cost of 239.67 thousand dollars. Baseline characterlistisc and outcomes Total percutaneous LAAC (estimated from sample) 7550 Age, years 66.83±0.34 Male, % 59.04 White, % 80.41 Mean Charlson Comorbidity Index 1.74±0.31 Hypertension, % 76.75 Diabetes, % 29.23 CKD, % 21.42 Mean Time to procedure, days 1.98±0.11 Mortality, % 2.06 Length of Stay, days 10.77±0.25 Any Complication, % 19.6 Total Cost, thousand dollars 239.67±10.01 Values are reported as mean ± SD. Categorical variables are represented as frequency. Conclusion A total of 7550 percutaneous LAAC was performed in US in 2016. The procedure related mortality is 2.06%, with an average time to procedure of 1.98 days and a length of stay of 10.77 days.
