Aortic stenosis TAVR

Lars Sondergaard
During the last decade transcatheter aortic valve replacement (TAVR) has been established as a treatment for patients with severe aortic stenosis, who are at particularly high surgical risk. As compared with surgical aortic valve replacement (SAVR), TAVR has been associated with lower early risk of mortality, atrial fibrillation, acute kidney injury and bleeding. Furthermore, device and peri-procedural improvements have addressed most of the initial limitations for TAVR, including the Achilles' heel, paravalvular leakage...

BACKGROUND: Right ventricular (RV) dysfunction and tricuspid regurgitation (TR) may coexist with aortic stenosis. The aim of this study was to assess the association between RV dysfunction, TR, associated comorbidities, and outcomes following transcatheter aortic valve replacement (TAVR). METHODS: A retrospective analysis was conducted of baseline and 6-month clinical and echocardiographic parameters, including TR grade, RV size (grade, end-diastolic and end-systolic areas, annular diameter), and function (grade, tricuspid annular plane systolic excursion [TAPSE], fractional area change, Tei index), in 519 consecutive TAVR patients...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) exposes the systemic vasculature to increased mechanical forces. Endothelial adaptation to mechanical stimuli is associated with angiogenic activation through various growth factors. We studied the potential angiogenic shift evoked by TAVR. METHODS: From a cohort of 69 consecutive patients undergoing TAVR, we excluded patients with conditions known to affect angiogenic factors, and serum vascular endothelial growth factor (VEGF) and angiopoietin (Ang)-1 and Ang-2 were assessed by ELISA...

BACKGROUND: Screening for internal carotid artery stenosis (ICAS) with Doppler ultrasound is commonly used before cardiovascular surgery. Nevertheless, the relationship between ICAS and procedure-related stroke in isolated aortic valve replacement is unclear. METHODS: We retrospectively reviewed patients with artery stenosis who underwent ICAS screening before surgical (SAVR) or transcatheter aortic valve replacement (TAVR) between January 2007 and August 2014. Logistic regression models were used to determine the relation between post-procedure stroke and total (sum of left and right ICAS) and maximal unilateral ICAS...

In recent years, the use of transcatheter aortic valve replacement (TAVR) has extended beyond the treatment of native aortic valve stenosis in patients with high surgical risk. TAVR is increasingly being performed for bioprosthetic aortic valve failure, i.e., the valve-in-valve (VIV) procedure. Establishing the success of a VIV procedure can be challenging in these cases. Furthermore, the limited availability of prostheses sizes further complicates the management of these patients. We present an unusual case of a repeat TAVR in a patient who previously had a VIV procedure in an aortic homograft...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has revolutionized management of high-risk patients with severe aortic stenosis. However, survival and the incidence of severe complications have been assessed in relatively small populations and/or with limited follow-up. OBJECTIVES: This report details late clinical outcome and its determinants in the FRANCE-2 (FRench Aortic National CoreValve and Edwards) registry. METHODS: The FRANCE-2 registry prospectively included all TAVRs performed in France...

Transcatheter aortic valve replacement (TAVR) is conventionally performed under general anesthesia (GA) allowing intraoperative transoesophageal echocardiogram imaging. We present our experience in patients having the procedure under local anesthesia (LA), who were subsequently transferred to a low dependency unit postprocedure, to assess safety and length of hospital stay. We retrospectively assessed all the transfemoral TAVR procedures conducted at our center from January 03, 2011. Of 216 patients, 145 had the procedure under GA and 71 under LA...

The superiority of transcatheter aortic valve replacement (TAVR) compared with medical therapy for patients with aortic stenosis (AS) who are not suitable candidates for surgery had been proven. Cardiopulmonary bypass (CPB) is rarely used in TAVR. Reports of early use of extracorporeal membranous oxygenator (ECMO) have promising outcomes. ECMO offers the option of cardiac support rescue in case of intraoperative hemodynamic instability and can be instituted in advance when hemodynamic instability is expected...

In older adults with aortic stenosis, we evaluated whether accelerometer-measured physical activity provides distinct clinical information apart from self-reported surveys or performance-based function tests. We employed wrist-mounted accelerometry in 52 subjects with severe aortic stenosis prior to transcatheter aortic valve replacement (TAVR). Daily daytime activity was estimated using the maximum 10 h of daily accelerometer-measured activity (M10) reported in activity counts. Subjects completed baseline surveys (New York Heart Association (NYHA), Short Form 12 (SF12), Kansas City Cardiomyopathy Questionnaire (KCCQ), EuroQol-5D (EQ-5D), Revised Life Orientation Test (LOT-R), Life Space, Detailed Activity Form) and performance-based function tests (Short Physical Performance Battery, 6-min walk test distance, grip strength) to estimate functional status...

Transcatheter aortic valve replacement (TAVR) with percutaneous coronary intervention (PCI) has emerged as a less-invasive therapeutic option for high surgical risk patients with aortic stenosis and coronary artery disease. The aim of this study was to determine the outcomes of TAVR when performed with PCI during the same hospitalization. We identified patients using the International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes from the Nationwide Inpatient Sample between the years 2011 and 2013...

Unicuspid aortic valve (UAV) offers unique challenges to transcatheter aortic valve replacement (TAVR), due to asymmetric expansion and apposition of the prosthesis during implantation. Although TAVR in bicuspid is now a well described experience, TAVR in unicuspid valve has not yet been described. A challenging case is described with TAVR in UAV using a Edwards Sapiens prosthesis via transapical approach. © 2016 Wiley Periodicals, Inc.

In the current era, 10-15 % of transcatheter aortic valve replacement (TAVR)-eligible high and prohibitive risk patients with severe symptomatic aortic stenosis are not candidates for transfemoral arterial access. Knowledge of the various alternative access options can enable TAVR teams to provide improved quality of life and potentially life-saving treatment for a group of patients who otherwise have no viable options. In this article, we review approach to patients with unfavorable femoral arterial anatomy and provide an in-depth discussion on the various alternative routes for TAVR...

BACKGROUND: Aortic valve replacement is indicated in patients with severe symptomatic aortic stenosis (AS). Transcatheter aortic valve replacement (TAVR) has evolved as a potential strategy in a growing proportion of patients in preference to surgical aortic valve replacement (SAVR). This meta-analysis aims to assess the differential outcomes of TAVR and SAVR in patients enrolled in published randomised controlled trials (RCTs). METHODS: A systematic literature search of Cochrane Library, EMBASE, OVID, and PubMed MEDLINE was performed...

The treatment of both aortic and now mitral valvular disease has been transformed through transcatheter valvular interventions. TAVR has rapidly become the treatment of choice for symptomatic severe aortic stenosis in both high, and now intermediate-risk patients. Building upon this success the last two years have seen the clinical introduction of transcatheter mitral valve replacement (TMVR), with a number of devices being utilised in first-in-man and feasibility studies. These experiences have helped determine the anatomical requirements and specifications that enable successful device deployment and avoidance of complications...

BACKGROUND: The use of transcatheter aortic valve replacement (TAVR) to treat aortic stenosis in the United States is growing, yet little is known about the variation in procedural outcomes in community practice. We developed a TAVR in-hospital mortality risk model and used it to quantify variation in mortality rates across United States (US) TAVR centers. METHODS AND RESULTS: We analyzed data from 22 248 TAVR procedures performed at 318 sites participating in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry (November 2011 to October 2014)...

BACKGROUND: Few studies have evaluated the clinical outcomes of transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve stenosis (AS). Particularly, limited data exist comparing the results of TAVR with new-generation devices versus early-generation devices. OBJECTIVES: This study sought to evaluate the clinical outcomes of TAVR for bicuspid AS with early- and new-generation devices. METHODS: The Bicuspid TAVR Registry is an international multicenter study enrolling consecutive patients with bicuspid AS undergoing TAVR between April 2005 and May 2015...

OBJECTIVES: The Registry of the Utilization of the TAo-TAVR approach using the Edwards SAPIEN Valve (ROUTE) was established to assess the effectiveness and safety of the use of transaortic (TAo) access for transcatheter aortic valve replacement (TAVR) procedures (NCT01991431). BACKGROUND: TAVR represents an alternative to surgical valve replacement in high-risk patients. Whereas the transfemoral access route is used commonly as the first-line approach, transapical access is an option for patients not suitable for transfemoral treatment mainly due to anatomic conditions...

Following the first successful transcatheter aortic valve replacement (TAVR) in 2002, TAVR has globally evolved to become a standard procedure in high-risk patients. Surgical aortic valve replacement in non-high-risk patients remains the gold standard for treatment of severe aortic stenosis. However, a paradigm shift appears to be occurring in the direction of treating lower-risk patients, and several studies have suggested its impact on clinical outcomes. In this review, we highlight the current status of TAVR in intermediate-risk patients and review major trials including Placement of AoRTic TraNscathetER (PARTNER) 2A randomized intermediate-risk trial using SAPIEN XT (Edwards Lifesciences Corp, Irvine, CA) recently presented with excellent outcomes and the lowest major complications rate at the American College of Cardiology's 65th Annual Scientific Session in Chicago...

BACKGROUND: Very elderly patients represent a distinct patient group in clinical setting in terms of a decision for trans-catheter aortic valve replacement (TAVR) when one considers the potential improvement in the quality of life (QoL) on one hand and the benefit to risk ratio on the other. This study aimed to compare functional and QoL outcomes of TAVR between octogenarians and septuagenarians. METHODS: This prospective cohort study included 136 elderly patients (70 to 89 years of age), who underwent transfemoral TAVR due to degenerative aortic stenosis...
