Objectives: This study sought to determine the association of chronic kidney disease (CKD) with in-hospital outcomes of transcatheter aortic valve replacement (TAVR)., Background: CKD is a known independent risk factor for worse outcomes after surgical aortic valve replacement (SAVR). However, data on outcomes of patients with CKD undergoing TAVR are limited, especially in those on chronic dialysis., Methods: The authors used data from the 2012 to 2014 National Inpatient Sample database to identify all patients ≥18 years of age who underwent TAVR. International Classification of Diseases-Ninth Revision-Clinical Modification codes were used to identify patients with no CKD, CKD (without chronic dialysis), or end-stage renal disease (ESRD) on long-term dialysis. Multivariable logistic regression models were constructed using generalized estimating equations to examine in-hospital outcomes., Results: Of 41,025 patients undergoing TAVR from 2012 to 2014, 25,585 (62.4%) had no CKD, 13,750 (33.5%) had CKD, and 1,690 (4.1%) had ESRD. Compared with patients with no CKD, in-hospital mortality was significantly higher in patients with CKD or ESRD (3.8% vs. 4.5% vs. 8.3%; adjusted odds ratio [no CKD as reference]: 1.39 [95% confidence interval: 1.24 to 1.55] for CKD and 2.58 [95% confidence interval: 2.09 to 3.13] for ESRD). Patients with CKD or ESRD had a higher incidence of major adverse cardiovascular events (composite of death, myocardial infarction, or stroke), net adverse cardiovascular events (composite of major adverse cardiovascular events, major bleeding, or vascular complications), and pacemaker implantation compared with patients without CKD. Acute kidney injury (AKI) and AKI requiring dialysis were associated with several-fold higher risk-adjusted in-hospital mortality in patients in the no CKD and CKD groups. Moreover, the incidence of AKI and AKI requiring dialysis did not decline during the study period., Conclusions: Patients with CKD or ESRD have worse in-hospital outcomes after TAVR. AKI is associated with higher in-hospital mortality in patients undergoing TAVR and the incidence of AKI has not declined over the years., (Copyright © 2017 American College of Cardiology Foundation.

Background: ST-segment elevation myocardial infarction (STEMI) in patients with concomitant multivessel (MV) coronary artery disease (CAD) is associated with poor outcomes. Percutaneous coronary intervention (PCI) of the culprit-lesion only (CLO) as compared with a MV PCI approach to revascularization remains uncertain. Our objective is to gain a better understanding of the efficacy and safety of CLO as compared with MV PCI in patients with STEMI by conducting an updated meta-analysis., Methods: A comprehensive search of PubMed, CENTRAL, EMBASE, The Cochrane Central Register, the ClinicalTrials.gov Website, and Google Scholar databases of randomized controlled trials (RCTs) was performed., Results: Seven RCTs were included, enrolling a total of 2006 patients. We found that there was a significant reduction in major adverse cardiovascular events (MACE) (OR, 0.62; 95% CI, 0.43-0.90), cardiovascular mortality (OR, 0.46; 95% CI, 0.27-0.80), and repeat revascularization (RRV) (OR, 0.39; 95% CI, 0.30-0.51) favoring MV over the CLO approach for patients undergoing primary PCI. The number needed to treat in order to prevent one CV mortality, RRV, or MACE event is 47, 11, and 16 patients, respectively. No differences were observed between MV vs. CLO PCI for subsequent myocardial infarction (OR, 0.74; 95% CI, 0.40-1.39), all-cause mortality (OR, 0.78; 95% CI, 0.53-1.15), non-cardiovascular mortality (OR, 1.35; 95% CI, 0.74-2.48), all-bleeding events (OR, 0.82; 95% CI, 0.40-1.65), contrast-induced nephropathy (OR, 0.72; 95% CI, 0.33-1.54), and stroke (OR, 1.28; 95% CI, 0.47-3.46)., Conclusions: MV PCI significantly reduces the rate of MACE, CV mortality, and RRV without significant harm as compared to CLO PCI., (Copyright © 2016 Elsevier Ireland Ltd.
