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...

OBJECTIVES: We sought to assess angiographic, echocardiographic and hemodynamic grading of paravalvular leakage (PVL) after transcatheter aortic valve implantation (TAVI) with respect to prediction of 1-year mortality. BACKGROUND: Meaningful criteria for the severity of PVL are needed to allow intraprocedural guidance and patient management after TAVI. METHODS: We pooled the prospective TAVI databases of 2 German centers. During TAVI, PVL was assessed angiographically and by the aortic regurgitation index (ARI)...

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...

Aims: To assess the incidence, management and long-term outcomes of transcatheter heart valve thrombosis (THVT). Methods and results: Between August 2007 and February 2016, 1396 patients were included in the Bern TAVI Registry and prospectively followed-up through echocardiographic and clinical evaluation. THVT was suspected in case of: (i) a mean transvalvular pressure gradient greater than 20 mmHg at transthoracic echocardiography, or (ii) an increase of more than 50% of the mean transvalvular pressure gradient compared with previous measurements or (iii) new symptoms or signs of heart failure with the presence of thrombus documented by transoesophageal echocardiography or multi-slice computed tomography...

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...

A 62-year old male with pulmonary fibrosis and aortic valve stenosis underwent TAVI (Corevalve Evolut XL 34 mm) in the build-up for lung transplantation (LuTx). Following post-dilation for a large annular perimeter, moderate paravalvular aortic regurgitation (AR) was observed. After 6 weeks, he was admitted to the ICU with respiratory failure(A). TTE demonstrated residual mild AR (based on a small excentric paravalvular AR jet, <10% circumferential extent, pressure half-time was not reliably measured) and together with borderline elevated NT-pro-BNP, the consultant cardiologist authorized LuTx listing...

BACKGROUND: Post-implantation paravalvular leak (PVL) remains a significant complication of transcatheter aortic valve implantation (TAVI). More importantly, its occurrence may impact long-term mortality. AIM: We sought to evaluate the effects of balloon post-dilatation (PD) on the reduction of PVL and mortality in patients undergoing TAVI. METHODS: A total of 101 consecutive patients undergoing TAVI were enrolled. Angiography, echocardiography, and the aortic regurgitation index (ARI) were used to assess the severity of PVL before and after balloon PD...

REVIEW
Satoshi Nakatani
Although clinically significant valve thrombosis after transcatheter aortic valve implantation (TAVI) is rare, the incidence of subclinical leaflet thrombosis has been reported to be up to about 10%-15%. It is mostly found 1-3 months after procedure in any type of transcatheter heart valve. Leaflet thrombosis is detected by high-resolution CT in the form of limited valve opening/closure and hypoattenuated leaflet thickening. Transthoracic or transesophageal echocardiography is capable of detecting limitations of valve motion, leaflet thickening, increased flow velocity across the valve...

AIMS: In the minimalist transcatheter aortic valve implantation (TAVI) era, the usage of transesophageal echocardiography becomes restricted. Conversely, aortography gains clinical ground in quantifying prosthetic valve regurgitation (PVR) during the procedure. In a mock circulation system, we sought to compare the contrast volume required and the accuracy of aortographic videodensitometric PVR assessment using a synchronized diastolic and standard (non-synchronized) injection aortography...

Transcatheter aortic valve implantation (TAVI) has proven to be the standard of care for patients with prohibitive and high operative risk; today, it is considered a reasonable alternative to surgical aortic valve replacement in intermediate-risk patients. As indications for TAVI move toward patients at lower risk, safety aspects are becoming even more important. Furthermore, adequate patient selection is key for predictable procedural success with minimal complications, translating into an optimal clinical outcome...
