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...

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...

Intravascular hemolysis (IVH) has been identified in patients with surgical prosthetic valves, but few have been reported after transcatheter aortic valve implantation (TAVI). We conducted a prospective analysis of 64 TAVI patients. The hemolysis profiles were collected at baseline and 6 months after TAVI. The echocardiography was performed at baseline and 6 months after TAVI. There are 14 patients (21.9%) with IVH before and 24(37.5%) after TAVI. The serum haptoglobin values before and 6 months after TAVI are 126...

BACKGROUND: While transcatheter aortic valve implantation (TAVI) has traditionally been supported intraprocedurally by transoesophageal echocardiography (TOE), transthoracic echocardiography (TTE) is increasingly being used. We evaluated echocardiographic imaging characteristics and clinical outcomes in patients who underwent TTE during TAVI (TTE-TAVI). METHODS AND RESULTS: A select team of dedicated sonographers and interventional echocardiographers performed TTE-TAVI in 278 patients, all of whom underwent TAVI through transfemoral access...

Accurate aortic annulus sizing is key for selection of appropriate transcatheter aortic valve implantation (TAVI) prosthesis size. The present study compared novel automated 3-dimensional (3D) transesophageal echocardiography (TEE) software and multidetector row computed tomography (MDCT) for aortic annulus sizing and investigated the influence of the quantity of aortic valve calcium (AVC) on the selection of TAVI prosthesis size. A total of 83 patients with severe aortic stenosis undergoing TAVI were evaluated...

A 80-year-old man was admitted to catheterization room for an acute infero-lateral ST-elevation myocardial infarction (STEMI). Coronary angiography showed a thrombotic occlusion of the second left marginal branch, and normal other coronary arteries. The thrombo-embolic mechanism of the STEMI, and the infectious context in this patient who had had a transcatheter aortic valve implantation (TAVI) two months earlier, led us to suspect a bioprosthesis endocarditis. It was confirmed by transthoracic and transoesophageal echocardiography, which showed an aortic-mitral curtain abscess and aortic bioprosthesis vegetations, associated to Enterococcus faecalis bacteriemia...

Enlarging or "cracking" a surgical stented bioprosthetic valve during valve-in-valve transcatheter aortic valve implantation (TAVI) increases orifice area, reducing transvalvular energy losses. We demonstrate that TAVI with valve cracking can be used to treat paravalvular leak (PVL) while providing optimal aortic valve physiology. A 61-year-old woman with a history of aortic valve replacement with a stented bioprosthesis presented with heart failure. Transthoracic echocardiography revealed severe prosthetic aortic valve stenosis with PVL and severe regurgitation...
