Sex-based differences in outcomes have been shown to affect caregiving in medical disciplines. Increased spending due to postacute care transfer policies has led hospitals to further scrutinize patient outcomes and disposition patterns after inpatient admissions. We examined sex-based differences in rehabilitative service utilization after transcatheter aortic valve implantation (TAVI). ⋯ On multivariable logistic regression, female sex was an independent predictor for disposition to rehabilitation facilities after TAVI (odds ratio 2.17; 95% confidence interval: 1.88 to 2.50; p < 0.001). Other independent predictors for females discharged to rehabilitation included the presence of rheumatoid arthritis and collagen vascular disease, body mass index greater than 30 kg/m2, depression, and sum of Elixhauser co-morbidities (all p < 0.001). In conclusion, nonhome discharge TAVI patients added LOS and hospital costs compared to home discharge TAVI patients, and female sex was one of the major predictors despite the lower co-morbidities.

Comparative Study
Comparison of Outcomes of Transcatheter Versus Surgical Aortic Valve Replacement in Patients ≥80 Years of Age.
Transcatheter aortic valve implantation (TAVI) procedures have increased exponentially since FDA approval in 2011. Older patients who underwent aortic valve replacement, either TAVI or surgical aortic valve replacement (SAVR), have elevated risk. Using the National Readmission Database, we included patients ≥80 years who underwent either TAVI or SAVR from 2011 to 2015. ⋯ Overall, the number of SAVR procedures remained two thirds higher than TAVI. In conclusion, in octo- and nonagenarians, TAVI is an effective and safer alternative to SAVR as it is associated with lower in-hospital mortality, lower major in-hospital complications, lower 30-day readmission rate, and hospital costs. Despite this, SAVR remained the most common approach in octogenarians, although the trends in this data set, suggest a shift in practice patterns for this cohort.

Association of Autoimmune Connective Tissue Disease and Outcomes in Patients Undergoing Transcatheter Aortic Valve Implantation.
Patients with autoimmune connective tissue disease (CTD) are at higher risk for developing aortic valve pathology, but the safety and value of transcatheter aortic valve implantation (TAVI) in this population has not been investigated. This study evaluated mortality, complication, and readmission rates along with length of stay and total costs after TAVI in patients with CTD. We retrospectively reviewed 47,216 patients who underwent TAVI from the National Readmissions Database between January 2011 and September 2015. ⋯ However, CTD patients were more frequently readmitted for postoperative infection (9.4 vs 5.6%, p = 0.042) and septicemia (8.2 vs 4.5%, p = 0.019). After multivariable adjustment, CTD patients faced lower mortality at index hospitalization (odds ratio [OR] 0.56 [0.38 to 0.82], p = 0.003) but were more frequently readmitted for septicemia (OR = 1.95 [1.10 to 3.45], p = 0.023) and postoperative infection (OR = 3.10 [1.01 to 9.52], p = 0.048) relative to non-CTD patients. In conclusion, CTD is not a risk factor for in-hospital mortality but is an independent risk factor for infectious complications post-TAVI.

Randomized Controlled Trial Multicenter Study
Usefulness of Clopidogrel Loading in Patients Who Underwent Transcatheter Aortic Valve Implantation (from the BRAVO-3 Randomized Trial).
P2Y12-inhibitor initiation with clopidogrel using a loading dose (LD) versus no LD (NLD) provides more rapid inhibition of platelet activation and reduced risk of ischemic events after coronary stenting. Whether a similar beneficial effect is achieved in the setting of transcatheter aortic valve implantation (TAVI) is unknown. We evaluate the effects of preprocedural clopidogrel LD versus no NLD on 48-hour and 30-day clinical outcomes after TAVI. ⋯ Multivariable adjustment showed that clopidogrel LD did not affect any of the studied clinical events, including major vascular complications (odds ratio 0.91, 95% confidence interval 0.60 to 1.39, p = 0.67). Also patients on clopidogrel maintenance therapy and thus considered in steady state were not at reduced risk of major adverse cardiovascular events compared with patients not on clopidogrel (3.7% vs 5.2%, p = 0.36). In conclusion, in patients who underwent TAVI, use of clopidogrel LD was associated with higher vascular complications and otherwise similar clinical events compared to NLD patients.

Multicenter Study
In-Hospital Outcomes of Transcatheter Aortic Valve Implantation in Patients With Mitral Valve Stenosis.
Little is known about the outcome of patients with mitral stenosis (MS) who underwent transcatheter aortic valve implantation (TAVI). Therefore, we sought to evaluate the potential impact of MS on the outcome of patients who underwent TAVI using the US national cohort. Using weighted data from the National Inpatient Sample database between 2011 and 2015, we identified patients who had undergone a TAVI as a primary procedure. ⋯ A total of 62,110 patients underwent TAVI (mean age 81 ± 8.72, 47.4% females, and 3.7% African-Americans) and 887 patients had MS (1.43%). Patients with concomitant MS had higher in-hospital mortality (5.1% vs 3.5% adjusted odds ratio [aOR] 1.455; 95% confidence interval [CI] 1.059 to 2.001, p = 0.021), major adverse cardiac events (9.0% vs 7.1% aOR 1.297; 95% CI 1.012 to 1.663, p = 0.040), major bleeding (16.3% vs 12.1% aOR 1.303; 95% CI 1.067 to 1.593, p = 0.010), cardiac complications (21.8% vs 16.0% aOR 1.536; 95% CI, 1.300 to 1.815, p < 0.001), and acute myocardial infarction (4.5% vs 2.8% aOR 1.783; 95% CI 1.249 to 2.545, p = 0.007) when compared with patients without MS. In conclusion, MS is an independent risk factor for mortality and morbidity after TAVI procedure for patients with severe aortic stenosis.
