BACKGROUND: The current study aims to identify predictors of extended postoperative length of stay (PLOS) after uncomplicated transcatheter aortic valve replacement (TAVR).
METHODS: Patients who underwent TAVR at a single center between June 2012 and June 2016 were analyzed. Patients were stratified by time into an early cohort (EC; 2012-2014) and current cohort (CC; 2015-2016). Those who had complications post procedure were excluded. The CC group was dichotomized based on its median PLOS. Factors associated with a longer PLOS were investigated by using multivariable logistic regression analysis.
RESULTS: Mean age of the 686 patients (299 in the EC group and 387 in the CC group) was 82 ± 8 years. PLOS in the CC group was significantly lower than in the EC group (4 days vs 6 days, respectively; P<.001). Median PLOS in the CC group was 2 days. Dichotomizing the CC group by median PLOS resulted in 148 patients (54%) ≤2 days vs 128 patients (46%) >2 days. Of these, PLOS was 1 day in 71 patients (26%) and 2 days in 61 patients (28%). Independent predictors of PLOS >2 days were non-transfemoral approach, non-elective admission, female sex, low mean transaortic gradient, presence of chronic renal failure, and pulmonary hypertension.
CONCLUSION: Experience coupled with improvements in TAVR technology over the past few years have led to a significant decrease in PLOS after TAVR. In the current TAVR era, 1 out of every 2 patients stays for a day or two in the absence of perioperative adverse events.
