PURPOSE: Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure in which a prosthetic heart valve is placed and expanded within a defective aortic valve. The device placement is commonly performed using two-dimensional fluoroscopic imaging. Within this work, we propose a novel technique to track the motion and deformation of the prosthetic valve in three dimensions based on biplane fluoroscopic image sequences. METHODS: The tracking approach uses a parameterized point cloud model of the valve stent which can undergo rigid 3D transformation and different modes of expansion...

BACKGROUND: Previous studies have demonstrated that three-dimensional (3D) transesophageal echocardiography (TEE) is an alternative to multi-detector computed tomography (MDCT) for aortic valve sizing in transcatheter aortic valve replacement (TAVR). However, conventional cross-sectional analysis of aortic annulus by 3D TEE has some limitations such as lengthy analytical time. A novel software for automated valve measurement has been developed for 3D TEE. We evaluated the accuracy and analytical time of aortic annular measurements using this novel automated software in the clinical setting...

BACKGROUND: Accurate aortic annulus (AoA) sizing is crucial for transcatheter aortic valve implantation planning. Three-dimensional (3D) transesophageal echocardiography (TEE) is a viable alternative to the standard multidetector row computed tomography (MDCT) for such assessment, with few automatic software solutions available. The aim of this study was to present and evaluate a novel software tool for automatic AoA sizing by 3D TEE. METHODS: One hundred one patients who underwent both preoperative MDCT and 3D TEE were retrospectively analyzed using the software...

Adaptation and evolution of transcatheter aortic valve replacement (TAVR) technologies has led to approval of TAVR for consideration in patients at intermediate risk for surgical aortic valve intervention. As TAVR becomes more mainstream, attention is shifting toward percutaneous mitral valve (MV) repair and transcatheter MV replacement (TMVR) techniques. Transcatheter heart valves (both purpose-built and off-label-use TAVR valves) are being implanted during TMVR procedures to treat clinically significant MV disease (native disease, degenerated bioprosthetic valves, and dysfunctional surgical MV annuloplasty repairs) when the risk of open heart MV surgery is prohibitive...

Aims: Echocardiography and tomographic imaging have documented dynamic changes in aortic stenosis (AS) geometry and severity during both the cardiac cycle and stress-induced increases in cardiac output. However, corresponding pressure gradient vs. flow relationships have not been described. Methods and results: We recruited 16 routine transcatheter aortic valve implantations (TAVI's) for graded dobutamine infusions both before and after implantation; 0.014″ pressure wires in the aorta and left ventricle (LV) continuously measured the transvalvular pressure gradient (ΔP) while a pulmonary artery catheter regularly assessed cardiac output by thermodilution...

We report the first successful valve-in-valve (ViV) implantation into a failed Edwards Biophysio surgical prosthesis (Edwards Lifesciences, Irvine, CA) and also the first use of the J-Valve system (Jie Cheng Medical Technologies, Suzhou, China) in a ViV configuration. A 77-year old male had symptomatic severe aortic stenosis secondary to failure of a 25 mm Biophysio bioprosthetic valve implanted 11 years previously, along with concomitant coronary artery bypass grafting. Transthoracic echocardiography (TTE) revealed calcified leaflets, a mean aortic gradient of 50 mm Hg, and an estimated valve area of 0...

OBJECTIVE: Performing transfemoral transcatheter aortic valve implantation (TAVI) without general anaesthesia (GA) has been increasingly adopted. We sought to study the impact of GA and non-GA approaches on procedural outcome and 30-day and 1-year mortality in transfemoral TAVI. METHODS: The UK TAVI registry holds information for every TAVI procedure in the UK. We analysed the data for patients implanted during 2013-2014 using either an Edwards Sapien or a Medtronic CoreValve prosthesis...

Leaflet motion abnormalities are a relatively new entity in the field of transcatheter aortic valve implantation and are associated with a range of different conditions, the extreme being prosthetic valve dysfunction with high gradients or central regurgitation and possibly early thrombotic degeneration. Another extreme condition is the incidental finding of leaflet thickening, but with normal transvalvular gradients. Transthoracic echocardiography is a useful screening tool for the detection of symptomatic thrombosis, but it has limited use in the detection of subclinical thrombosis and/or motion abnormalities alone...

BACKGROUND:  Paravalvular aortic regurgitation (PVAR) remains a frequent postprocedural concern following transcatheter aortic valve replacement (TAVR). Persistence of flow turbulence results in the cleavage of high-molecular-weight von Willebrand multimers, primary haemostasis dysfunction and may favour bleedings. Recent data have emphasized the value of a point-of-care measure of von Willebrand factor-dependent platelet function (closure time [CT] adenosine diphosphate [ADP]) in the monitoring of immediate PVAR...

INTRODUCTION: Aortic stenosis is the most common significant valvular disease in the western world. These patients are treated operatively unless they are at high operative risk or inoperable. During the last decade an alternative approach has evolved - transcatheter aortic valve implantation (TAVI). This method was shown to be at least as effective and safe as the operative one. However, very little data exists on long term follow-up (5 years and above), especially regarding valve durability and patient survival...

BACKGROUND: The new CoreValve Evolut R has an improved design to minimize paravalvular leakage (PVL) and allows repositioning of the valve. For patients with degenerated bioprosthetic aortic valves, transcatheter aortic valve implantation (TAVI) represents a less invasive option. Herein reported are valve-in-valve (ViV) implantations of this new valve. METHODS: A total of 26 patients (mean age 79.4 ± 6.1 years, 17 males and 9 females) were treated for severe prosthesis stenosis (n = 9), severe regurgitation (n = 8) or severe combination of stenosis and regurgitation (n = 9)...

BACKGROUND: Few data exist on patients with low-flow, low-gradient aortic stenosis (LFLG-AS) undergoing transcatheter aortic valve replacement (TAVR). Also, very scarce data exist on the usefulness of dobutamine stress echocardiography (DSE) before TAVR in these patients. OBJECTIVES: The authors sought to evaluate clinical outcomes and changes in left ventricular ejection fraction (LVEF) following TAVR in patients with classical LFLG-AS. METHODS: This multicenter registry included 287 patients with LFLG-AS undergoing TAVR...

This original clinical research study id focused on description of baseline anatomy and outcomes after transcatheter aortic valve implantation (TAVI) in patients presenting with severe aortic stenosis (AS) and bicuspid aortic valve (BAV). We compared this BAV population with a population of patients with AS and tricuspid aortic valves after a propensity score matching developed by a multivariate logistic regression according to a non-parsimonious approach. Baseline anatomical characteristics were obtained by transthoracic echocardiography (TTE) and multi-sliced computed tomography (MSCT) and compared by chi-square and t-student tests...

Transcatheter aortic valve implantation (TAVI) is an effective and less invasive treatment for the increasing population of individuals with severe aortic stenosis (AS). Echocardiography is crucial in the assessment of AS patients from pre- to post-procedure. Transthoracic echocardiography (TTE) may be used to assess patient suitability for TAVI, as well as evaluate the severity of AS, the aortic valve complex, aortic valve morphology, mitral regurgitation (MR), and left ventricular function. Transesophageal echocardiography (TEE) is usually used as an intra-procedural monitoring tool to provide feedback during the procedure, to assess prosthetic valve function, and to detect complications rapidly before and after balloon aortic valvuloplasty (BAV) or transcatheter heart valve (THV) deployment...

An 18-month-old male Akita Inu dog developed fever and lameness 8 months after successful transcatheter closure of a patent ductus arteriosus with an Amplatz Canine Duct Occluder (ACDO). Corynebacterium species were cultured from 3 blood samples. Echocardiography showed a vegetative process on the aortic valves. The dog died spontaneously 3 days after development of the initial signs. Necropsy confirmed the presence of bacterial ductal arteritis and myocarditis, and revealed an incomplete endothelialization of the intraductal metal implant...
