RESUMO
INTRODUCTION: Transcatheter aortic valve replacement (TAVR) has become a suitable alternative to surgical aortic valve replacement (SAVR) for the treatment of symptomatic severe aortic stenosis (AS). A high proportion of patients with AS have mixed aortic valve disease (MAVD) with mild or more concurrent aortic regurgitation (AR). Differential outcomes of TAVR among patients with AS and MAVD have not been well characterized. We compared 1-year mortalities following TAVR among patients with MAVD and AS. METHODS: We conducted a meta-analysis of studies published in PubMed/Medline. The primary outcome was 1-year all-cause mortality following TAVR among patients with MAVD vs. AS. Secondary endpoints were: (1) incidence of AR within 30 days following TAVR (post TAVR AR); and (2) 1-year all-cause mortality within each group stratified according to severity of post TAVR AR. RESULTS: Nine studies involving 9505 participants were included in the analysis. At 1 year following TAVR, mortality was lower in MAVD than in AS; HR 0.89, 95% CI 0.81-0.98. The mortality advantage increased when pre-TAVR AR was moderate or more; HR 0.84, 95% CI 0.72-0.99. The mortality advantage was attenuated after correction for publication bias. There was a higher risk of post TAVR AR in the MAVD group; OR 1.51, 95% CI 1.20-1.90 but the impact on mortality of moderate vs. mild post TAVR AR was greater among patients with AS than in patients with MAVD HR 1.67 95% CI 0.89-3.14 vs. 0.93 95% CI 0.47-1.85. CONCLUSIONS: Patients with MAVD have similar or improved survival 1 year after TAVR compared to those with AS.
RESUMO
INTRODUCTION: There is a paucity of data regarding the outcomes of transcatheter aortic valve replacement (TAVR) among patients with thoracic or abdominal aortic aneurysms (AA). Using the Nationwide Inpatient Sample (NIS) database, we explored the safety of TAVR among patients with a diagnosis of AA. METHODS: We queried the National Inpatient Sample database (2012-2017) for hospitalized patients undergoing TAVR, using ICD-9 and ICD-10 codes for endovascular TAVR. Reports show that > 95% of endovascular TAVR in the US is via transfemoral access, so our population are mostly patients undergoing transfemoral TAVR. Using propensity score matching, we compared the trends and outcomes of TAVR procedures among patients with versus without AA. RESULTS: From a total sample of 29,517 individuals who had TAVR procedures between January 2012 and December 2017, 910 had a diagnosis of AA. In 774 matched-pair analysis, all-cause in-hospital mortality was similar in patients with and without AA OR 0.63 [(95% CI 0.28-1.43), p = 0.20]. The median length of stay was higher in patients with AA: 4 days (IQR 2.0-7.0) versus 3 days (IQR 2.0-6.0) p = 0.01. Risk of AKI [OR 1.01 (0.73-1.39), p = 0.87], heart block requiring pacemaker placement [OR 1.17 (0.81-1.69), p = 0.40], aortic dissection [OR 2.38 (0.41-13.75), p = 0.25], acute limb ischemia [OR 0.46 (0.18-1.16), p = 0.09], vascular complications [OR 0.80 (0.34-1.89), p = 0.53], post-op bleeding [OR 1.12 (0.81-1.57), p = 0.42], blood transfusion [OR 1.20 (0.84-1.70), p = 0.26], and stroke [OR 0.58 (0.24-1.39), p = 0.25] were similar in those with and without AA. CONCLUSIONS: Data from a large nationwide database demonstrated that patients with AA undergoing TAVR are associated with similar in-hospital outcomes compared with patients without AA.
