Trends in vascular complications and associated treatment strategies following transfemoral transcatheter aortic valve replacement

Background: Transcatheter aortic valve replacement (TAVR) may be an effective option for high-risk AR patients. Although international experiences of TAVR for AR are published, U.S. data is limited. The primary objective of this study was to investigate periprocedural and 30-days outcomes in terms of mortality and post-procedural complications in patients undergoing TAVR for AR using large national U.S. databases. Hypothesis: TAVR is a promising option in AR Methods: Study cohorts were derived from Nationwide Inpatient Sample (NIS) and Nationwide Readmissions Database (NRD) 2016-17. TAVR and AR were identified using ICD-10-CM-codes. The key outcomes were all-cause mortality, disabling stroke, valvular complications, complete heart block (CHB)/ permanent pacemaker placement (PPM), open heart surgery, acute kidney injury (AKI) requiring dialysis, and vascular complications. Multivariate logistic regression was used to adjust for confounders. Results: 915 patients from the NIS (male-71%, age 65-84.2%) and 822 patients from the NRD (male-69.3%, age 65-80.5%) underwent TAVR for AR. The median length of stay (LOS) was 4 days for both cohorts. In-hospital mortality was 2.7% in NIS and 30-day mortality was 3.3% in NRD. Disabling strokes were noted in 0.6% peri-procedurally and 1.8% at 30-days. Valve-related complications were 18-19% with paravalvular leak being the most common. Approximately 11% of patients developed CHB and/or needed PPM in both cohorts. In NRD, 2.2% of patients required dialysis for AKI, 1.5% developed vascular complications, and 0.6% required open-heart surgery within 30-days post-procedure. Anemia was predictive of increased overall complications and valvular complications, whereas, peripheral vascular disease was predictor of increased valvular complications and CHB/PPM. Conclusion: TAVR is a promising option in AR. Further studies are necessary for the expansion of TAVR as standard treatment in AR.

Transcatheter Aortic Valve

Abstract Transcatheter Aortic valve Replacement (TAVR) has emerged as an alternative to surgical aortic valve replacement for patients considered at high or prohibitive operative risk. It is widely known the short and mid-term outcomes, however, is limited about long-term outcomes in according to age. The aim of this study was to determine the survival and the clinical outcomes on based of age. after TAVR with the CoreValve prosthesis. Methods From April 2008 to December 2017, the CoreValve and Sapiens 3 prosthesis were implanted in 667 patients with symptomatic severe aortic stenosis with deemed high risk on base to age, <80 years and ≥80 years old Results The mean age in patients <80 compared with ≥80 years, was 73.6±7 vs. 83.4±2.8 years and the logistic EuroSCORE and STS score were 16.3±11% vs. 18.1±11%. In-hospital mortality was 3.4%, and the combined endpoint of death, vascular complications, myocardial infarction, majopr bleeding or stroke had a rate of 18.3%. The late mortality (beyond 30 days) was 40.5%. When compared both groups, there were no differences for the presence of threatening bleeding 3.5% vs. 3.6% (HR = 1.033 [IC95% 0.452–2.360], p=0.557), myocardial infarction4.2% vs. 2.9% (HR = 0.67 [IC95% 0.290–1,530], p=0.0.226), stroke 8.9% vs. 9.4% (HR = 1.067 [IC95% 0.625–1.821], p=0.814) and mortality 44.5% vs. 41.1% (HR=0.971388 [IC95% 0.639–1.188], p=0.214) and there was difference in between groups in hospitalizations for heart failure 13.8% vs. 7.7% (HR = 1.374 [IC95% 1.037–1.821], p=0.008. Survival at 1, 2, 3, 4, 5 were similar in both groups (86.9% vs. 89.8%, 78.4 vs. 78.3%, 65.5 vs. 72.5%, 57.9% vs. 62.8% and 51.1 vs. 52.8%>; log Rank 0.992, p=0.319), respectively, after a mean follow-up of 43.9±27 months. Conclusions TAVR is associated with significant survival benefit throughout 3.2 years of follow-up. Survival during follow-up was similar in patients with <80 compared with ≥80 years old.
