BACKGROUND: Transcatheter aortic valve replacement (TAVR) is typically performed under general anesthesia (GA). However, there is increasing data supporting the safety of performing TAVR under local anesthesia/conscious sedation (LA). We performed a meta-analysis to gain better understanding of the safety and efficacy of LA versus GA in patients with severe aortic stenosis undergoing TAVR. METHODS AND RESULTS: We comprehensively searched EMBASE, PubMed, and Web of Science...

OBJECTIVES: This study sought to determine if indexed effective orifice area (EOAi), using left ventricular outflow tract measured from computed tomography (EOAiCT), reclassified prosthesis-patient mismatch (PPM) compared with conventional echocardiogram-defined measurements (EOAiTTE). BACKGROUND: PPM does not predict mortality following transcatheter aortic valve replacement (TAVR). However, it is unknown if the EOAiCT of the left ventricular outflow tract improves risk stratification...

OBJECTIVES: This study sought to assess the influence of baseline right bundle branch block (RBBB) on all-cause and cardiovascular mortality as well as sudden cardiac death (SCD) among patients undergoing transcatheter aortic valve replacement (TAVR). BACKGROUND: Few data exist regarding the late clinical impact of pre-existing RBBB in TAVR recipients. METHODS: A total of 3,527 patients (mean age 82 ± 8 years, 50.1% men) were evaluated according to the presence of RBBB on baseline electrocardiography...

INTRODUCTION AND OBJECTIVES: There is uncertainty on the correct management of antithrombotic therapies after transcatheter aortic valve replacement (TAVR), with dual antiplatelet therapy (DAPT) being currently recommended on an empirical basis. The aim of the present meta-analysis was to assess the safety and effectiveness of DAPT in patients undergoing TAVR. METHODS: Studies comparing different antithrombotic regimens after TAVR were included. The primary endpoint was 30-day overall mortality...

Access options for transcatheter aortic valve replacement (TAVR) currently include transfemoral, transaortic, transapical, transsubclavian, and other approaches. Transsubclavian access for balloon expandable valves is gaining popularity when transfemoral access is not suitable, given its peripheral access compared with central access. With the transsubclavian approach, second femoral or radial artery access is necessary for pigtail catheter placement. We describe a "double-stick" transsubclavian technique that eliminates secondary arterial access...

Prosthetic valve endocarditis is a very grave and often terminal disease. Surgical valve replacement remains the cornerstone treatment for this disease. However, it is often contraindicated. Herein, we describe the implantation under direct visualization of a self-expandable transcatheter heart valve in a prohibitive surgical risk patient with homograft aortic valve endocarditis.

In the last few years, several studies, each with different aim and modeling detail, have been proposed to investigate transcatheter aortic valve implantation (TAVI) with finite elements. The present work focuses on the patient-specific finite element modeling of the aortic valve complex. In particular, we aim at investigating how different modeling strategies in terms of material models/properties and discretization procedures can impact analysis results. Four different choices both for the mesh size (from  20 k elements to  200 k elements) and for the material model (from rigid to hyperelastic anisotropic) are considered...

Patients with inoperable, high-risk, and intermediate-risk aortic stenosis can now be treated with transcatheter aortic valve replacement. Centers for Medicare and Medicaid Services and the Food and Drug Administration selectively choose centers based on experience and require a collaborative, multidisciplinary team approach in the treatment and decision making for these patients. The work-up has been streamlined. Gated multislice computed tomography angiogram has emerged as the gold standard for assessment of valve anatomy and sizing of the transcatheter heart valve...

BACKGROUND: Randomized trials support the use of transcatheter aortic valve replacement (TAVR) for the treatment of aortic stenosis in high- and intermediate-risk patients, but the generalizability of those results in clinical practice has been challenged. OBJECTIVES: The aim of this study was to determine the safety and effectiveness of TAVR versus surgical aortic valve replacement (SAVR), particularly in intermediate- and high-risk patients, in a nationally representative real-world cohort...

OBJECTIVES: The aim of this study was to examine the frequency, timing, and association of access-site and non-access-site bleeding with mortality in the setting of transcatheter aortic valve replacement (TAVR) during long-term follow-up. BACKGROUND: Bleeding is frequent and associated with impaired prognosis in patients undergoing TAVR. It is currently unknown whether the site of bleeding differentially influences the outcomes of TAVR patients. METHODS: In total, 926 consecutive patients undergoing TAVR from 2007 through 2014 were evaluated...

OBJECTIVES: The study sought to examine the effect of coronary artery disease (CAD) on mortality in patients undergoing transcatheter aortic valve replacement (TAVR). BACKGROUND: CAD is common in the TAVR population. However, there are conflicting data on the prognostic significance of CAD and its treatment in this population. METHODS: The authors analyzed 1,270 consecutive patients with severe aortic stenosis (AS) undergoing TAVR at 3 Israeli centers...

Involvement of the coronary ostia is a rare complication after transcatheter aortic valve replacement (TAVR). This complication has been more commonly described immediately after valve deployment. This is the first reported case of delayed coronary obstruction caused by TAVR 6 months after the procedure.

Background -Transcatheter heart valve (THV) thrombosis has been increasingly reported. In these studies, thrombus quantification has been based on 2D assessment of a 3D phenomenon. Methods -Post-procedural four-dimensional, volume-rendered CT (4DCT) data of CoreValve, Evolut R, and SAPIEN 3 transcatheter aortic valve replacement (TAVR) patients enrolled in the RESOLVE trial were included in this analysis. Patients on anticoagulation were excluded. SAPIEN 3 and CoreValve/Evolut R patients with and without hypo-attenuated leaflet thickening (HALT) were included in order to study differences between groups...

BACKGROUND: The role of three-dimensional transesophageal echocardiography (3DTEE) vs multidetector computed tomography (MDCT) in aortic annular sizing has been poorly defined in patients undergoing transcatheter aortic valve replacements (TAVR). We set to determine the correlation between 3DTEE and MDCT in measuring the aortic annulus prior to TAVR. METHODS: In an observational, retrospective study, we compared aortic annular areas measured by MDCT and 3DTEE in TAVR patients...

BACKGROUND: As transcatheter aortic valve replacement (TAVI) becomes more straightforward, a larger proportion of patients will be well enough to be discharged early. This study sought to characterise the clinical features that allowed patients to be discharged early after TAVI and to evaluate the safety of an early discharge policy. METHODS: All patients undergoing TAVI at the above cited centre from August 2007 to March 2015 were included in this study. Baseline characteristics, in-hospital outcomes, re-admissions and mortality were compared...

BACKGROUND: Early experience with leadless pacemakers has shown a low rate of complications. However, little is known about system revision in patients with these devices. OBJECTIVE: To describe the system revision experience with the Micra Transcatheter Pacing System (TPS). METHODS: Implanted patients from the Micra TPS and the Micra Continued Access study (N = 989) were analyzed and compared to 2667 patients with transvenous pacemakers (TVP)...
