Transcatheter aortic valve implantation (TAVI) has become the mainstream treatment for severe aortic stenosis. Despite improvement in device iteration and operator experience rigorous outcome data outside the scope of clinical trials is lacking. Nationwide readmission database 2016 and 2017 was utilized to identify the study population. ⋯ Multivariate analysis showed that nonagenarians, patients undergoing transapical TAVI, and patients with a higher comorbidity burden were more likely to be readmitted within 90 days. In conclusion, almost half of TAVI patients in the US are discharged within 48 hours after their procedure and 20% of all TAVI patients are readmitted within 90 days. Most readmissions are due to noncardiac causes.

We compared the long-term outcomes and difference in dilatation rates of the ascending aorta after aortic valve (AV) replacement (AVR) between bicuspid and tricuspid AV patients, and evaluated risk factors associated with ascending aorta dilatation and aortic events during the follow-up. Of 1,127 patients who underwent AVR from 1995 to 2015, 259 patients with a dilated ascending aorta (≥40 mm in diameter) were included. The patients were divided into those with bicuspid (group bicuspid aortic valve [BAV], n = 105) and with tricuspid (group tricuspid aortic valve [TAV], n = 154) AV, and a propensity score-matched analysis was performed to match 98 patients in each group. ⋯ Preoperative ascending aorta diameter showed a linear relationship with the dilatation rate of ascending aorta (p <0.001) and was related to progressive aortic dilatation and aortic events (odds ratio: 1.25, p <0.001 and hazard ratio = 1.56, p <0.001, respectively). In conclusion, the long-term outcomes and ascending aorta dilatation rate were similar between the BAV and TAV patients up to 15 years after AVR. Bicuspid AV was not a risk factor of mortality or aortic events.
