In year 2016, the American Society of Echocardiography (ASE) and the European Association of Cardiovascular Imaging (EACVI) updated Recommendations for the assessment and grading of diastolic dysfunction (DD). We aimed to assess the applicability of this DD grading method and its association with prognosis in patients with severe aortic stenosis (AS) who underwent transcatheter aortic valve implantation (TAVI). We retrospectively identified 237 consecutive patients with severe AS who underwent trans-femoral TAVI...

An 82-year-old woman was referred to our hospital because of dyspnea on effort. Echocardiography revealed severe aortic valve stenosis (AS). Simultaneously, chest computed tomography (CT) revealed a 19-mm nodule in the lower lobe of the right lung, and bronchoscopic biopsy revealed adenocarcinoma. She underwent transcatheter aortic valve implantation (TAVI) for severe AS. Three weeks later, she underwent lower lobectomy of the right lung and mediastinal dissection for the lung cancer. Her postoperative course was good, and she was discharged 8 days postoperatively...

Aortic stenosis is the most common valvular heart disease and the prevalence increases with age. Common symptoms include dyspnea, angina, and syncope. Echocardiography is a cornerstone in diagnosis of aortic stenosis. Severe aortic stenosis is defined as peak aortic jet velocity ≥4 m/s, a mean transvalvular gradient ≥40 mmHg, and/or an aortic valve area <1.0 cm2. The two-year mortality in patients with symptomatic aortic stenosis is 50 percent without intervention. The only efficient treatment is intervention, either open heart valve replacement or percutaneous transcatheter implantation of an aortic valve prosthesis (TAVI), which both provide symptomatic relief and improved survival...

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...

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...

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...

Background Increased exercise capacity favourably influences clinical outcomes after transcatheter aortic valve implantation. In our SPORT:TAVI randomised pilot trial, eight weeks of endurance and resistance training (training group, TG) shortly after transcatheter aortic valve implantation resulted in significantly improved exercise capacity, muscular strength and quality of life compared to usual care (UC). However, the long-term clinical benefits of such an intervention are unknown. Design A randomised controlled trial...

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...

AIMS: Paravalvular leak(PVL) remains an important issue in TAVI. The Edwards Sapien3(S3) valve has reduced PVL but up to one-third of patients remain with mild leak. Our study aims to identify predictors of mild PVL after TAVI with S3 valve. METHODS AND RESULTS: From 10/2015 to 5/2017, 122 consecutive patients underwent S3 TAVI for symptomatic severe aortic stenosis. 33 patients with mild PVL on transthoracic echocardiography at 30-day follow-up were compared to 89 with none/trace PVL...

OBJECTIVES: Although procedure-related new cardiac conduction disturbances (CCDs) remain an important issue in transcatheter aortic valve implantation (TAVI), their effect on myocardial function and overall patient outcome remains unclear. The goal of this study was to analyze the influence of procedure-related CCDs on systolic and diastolic LV performance and on patient survival after TAVI. METHODS AND RESULTS: Ninety-five patients who underwent TAVI for severe symptomatic aortic stenosis (AS) and had a complete follow-up were evaluated with respect to procedure-related CCDs...

The transcatheter aortic valve implantation (TAVI) consist an alternative treatment in patients with severe aortic stenosis. Multimodality imaging using transthoracic echocardiography (TTE) or transesophageal echocardiography (TOE) and multislice CT (MSCT) constitute cornerstone techniques for the pre-operative management, peri-procedural guidance, follow up and recognition of possible transcatheter valve related complications. CT angiography is much more accurate regarding the total definition of aortic annulus diameter and circumferential area...

BACKGROUND:  Transcatheter aortic valve implantation (TAVI) has evolved into an alternative procedure to surgical valve replacement for high-risk patients with aortic valve stenosis. Despite technical innovations, there is still a risk of complications during and after the intervention. After a TAVI procedure, ECG-gated multidetector computed tomography (MDCT) plays an important role in the early diagnosis of local complications. In this article, we explain for the first time how the technical acquisition of MDCT in the region of the aortic root is performed as post-interventional control of the TAVI prosthesis...

Transcatheter aortic valve implantation (TAVI) has revolutionized the treatment of elderly patients with symptomatic severe aortic valve stenosis. Among the possible TAVI complications, a rare one is the annular/left ventricular outflow tract rupture. We report a rare case of a late complex ventricular septal defect (VSD) following TAVI with a balloon-expandable prosthesis, conservatively managed. Our case demonstrates the role of 3D transthoracic echocardiography (3DTTE) in the accurate diagnosis of this TAVI complication and suggests that, in some cases, it can be used as an alternative to other diagnostic tools, such as transesophageal echocardiography, cardiac catheterization, and computed tomography...
