Background. Acute kidney injury (AKI) is a well-known complication following a transcatheter aortic valve replacement (TAVR) and is associated with higher morbidity and mortality. Objective. We aim to compare the risk of developing AKI after transfemoral (TF), transapical (TA), and transaortic (TAo) approaches following TAVR. Methods. We searched Medline and EMBASE databases from January 2009 to January 2021. We included studies that evaluated the risk of AKI based on different TAVR approaches. After extracting each study’s data, we calculated the risk ratio and 95% confidence intervals using RevMan software 5.4. Publication bias was assessed by the forest plot. Results. Thirty-six (36) studies, consisting of 70,406 patients undergoing TAVR were included. Thirty-five studies compared TF to TA, and only seven investigations compared TF to TAo. AKI was documented in 4,857 out of 50,395 (9.6%) patients that underwent TF TAVR compared to 3,155 out of 19,721 (16%) patients who underwent TA-TAVR, with a risk ratio of 0.49 (95% CI, 0.36–0.66; p < 0.00001 ). Likewise, 273 patients developed AKI out of the 1,840 patients (14.8%) that underwent TF-TAVR in contrast to 67 patients out of the 421 patients (15.9%) that underwent TAo-TAVR, with a risk ratio of 0.51 (95% CI, 0.27–0.98; p = 0.04). There was no significant risk when we compared TA to TAo approaches, with a risk ratio of 0.89 (95% CI, 0.29–2.75; p = 0.84). Conclusion. The risk of post-TAVR AKI is significantly lower in patients who underwent TF-TAVR than those who underwent TA-TAVR or TAo-TAVR.
Sex‐stratified analysis of the safety of percutaneous left atrial appendage occlusion
AbstractObjectives and BackgroundThere is insufficient current evidence about whether sex impacts outcomes of percutaneous left atrial appendage occlusion (LAAO). The aim of this study was to investigate the association between sex and short‐term outcomes of LAAO.MethodsPatients who were hospitalized and underwent LAAO from October 2015 to December 2017 in the National Readmission Database were queried. The primary endpoint of interest was major in‐hospital adverse events. Secondary endpoints included, 30‐day readmission rate, nonhome discharge, and cost of hospitalization. Propensity score matching (1:1) was performed to compare the outcomes among women and men.ResultsA total of 9,281 patients were included in the current analysis [women = 3,659 (39%); men = 5,622 (61%)]. Comparing women to men, women had lower prevalence of diabetes mellitus (30.6% vs 35.7%, p < .01), heart failure (28.6% vs 30.8%, p = .03), vascular disease (55.5% vs 69.6%, p < .01) and renal failure (18.3% vs 21.2%, p < .01), and higher CHA2DS2VASc score (5 [IQR4‐6] vs 4 [IQR3‐6], p < .01). After propensity‐score matching, women had higher rate of major in‐hospital adverse events (2.8% vs 1.9%; p < .01), and nonhome discharges (11.4% vs 6.7%; p < .01). Additionally, 30‐day readmission rate was higher among women (10% vs 8.6%, p = .03).ConclusionAmong hospitalized patients undergoing LAAO, women carry higher risk for major in‐hospital adverse events, nonhome discharge, and 30‐day readmission rates.
