Arora S, Hendrickson MJ, Strassle PD, et al. - Given that costs related to transcatheter aortic valve implantation (TAVI) as well as its burden to healthcare systems will assume greater importance in association with the continuous rapid growth of TAVI as a treatment approach for aortic stenosis, therefore, researchers evaluated trends in costs as well as risk factors of 30-day readmissions for TAVI. They used the Nationwide Readmission Database to select patients receiving TAVI between January 2012 and November 2017. The following factors were related to increased odds of 30-day readmissions: index TAVI hospitalizations complicated by acute kidney injury, length of stay ≥5 days, low hospital procedural volume, and skilled nursing facility discharge. Findings revealed a significant reduction in the costs of index hospitalizations and 30-day cost burden for TAVI in the U.S. from 2012-2017. However, an increment was noted in readmissions because of arrhythmia/heart block as well as their associated costs. To optimize outcomes and expenses with the ongoing expansion of TAVI, the importance of continued strategies to avert readmissions, particularly those for conduction disturbances, was highlighted.
