An 83-year-old man with severe symptomatic aortic valve stenosis underwent transcatheter aortic valve implantation (TAVI) using a 29 mm SAPIEN XT valve. He was haemodynamically stable, but developed haemolytic anaemia. Transthoracic echocardiography conducted 7 days after TAVI revealed an abnormal continuous flow from the right sinus of Valsalva adjacent to the implanted valve to the right ventricle. The amount of shunt flow was considered small and the patient was managed with diuretics successfully. He was discharged from the hospital 35 days after TAVI...

Aims: Scarce data are available on the long-term structural and functional changes of prosthetic valves after transcatheter aortic valve implantation (TAVI). The objective was to evaluate with echocardiography the long-term structural and functional changes of prosthetic valves after TAVI. Methods and results: Structural valve deterioration (SVD) was defined as leaflet thickening ≥3mm, presence of calcification and abnormal leaflet motion. Five-year echocardiographic follow-up was available in 96 out of 318 patients who underwent TAVI with a balloon-expandable device between April 2008 and December 2011...

OBJECTIVE: Transcatheter aortic valve implantation (TAVI) is a minimally invasive therapy for elderly patients with severe aortic valve stenosis who were refused surgical aortic valve replacement because of the high perioperative risk. Traditionally, this procedure has been done under general anesthesia, but more recently local anesthesia and sedation have become popular. This research assessed the effectiveness of transfemoral TAVI under bispectral index (BIS)-guided sedation. METHODS: In this single-center retrospective control analysis, clinical data, including demographic characteristics, echocardiography, periprocedural data, and main complications, were collected and assessed in 113 patients undergoing TAVI through the femoral artery under general anesthesia (GA group, n=36) and under BIS-guided sedation (SED group, n=77)...

Aims: High aortic valve calcification (AVC) assessed with CT may be used to differentiate between severe and non-severe aortic stenosis (AS). Nonetheless, in some cases patients with low calcification are diagnosed with haemodynamically severe AS. The prevalence, mechanism of valve stenosis and implications for transcatheter aortic valve implantation (TAVI) of low AVC severe AS remain unclear. We assessed the clinical and haemodynamic characteristics and the outcome of patients with severe AS and low AVC that undergo TAVI...

OBJECTIVES: : The aim of this study was to prove technical feasibility and document haemodynamic and clinical outcomes of transcatheter aortic valve implantation (TAVI) with the latest generation repositionable and retrievable Lotus™ transcatheter heart valve (THV) without prior balloon-aortic valvuloplasty (BAV). It has been demonstrated for self-expandable and balloon-expandable THV that implantation without prior BAV is not only feasible and safe but also results in lower fluoroscopy times and amounts of contrast agent while yielding non-inferior haemodynamic and clinical outcome...

REVIEW
Caroline Bleakley, Mehdi Eskandari, Mark Monaghan
Transcatheter aortic valve implantation (TAVI) was initially proven as an alternative to valve replacement therapy in those beyond established risk thresholds for conventional surgery. With time the technique has been methodically refined and offered to a progressively lower risk cohort, and with this evolution has come that of the significant imaging requirements of valve implantation. This review discusses the role of transoesophageal echocardiography (TOE) in the current TAVI arena, aligning it with that of cardiac computed tomography, and outlining how TOE can be used most effectively both prior to and during TAVI in order to optimise outcomes...

AIM: The role of transoesophageal echocardiography in cardiac interventional structural procedures is well established and appreciated. However, the need for general anaesthesia (GA) throughout the procedure remains a controversial issue. The aim of the present study is to assess the feasibility and imaging quality of using a transnasal microrobe that allows the usage of conscious sedation in patients that undergo cardiac structural interventional procedures without missing the benefits, guidance and navigation of conventional trans-procedural TEE...

BACKGROUND: Dual antiplatelet therapy (DAPT) is commonly used after transcatheter aortic valve implantation (TAVI); however, the supporting evidence is limited. To determine if aspirin alone is a better alternative to DAPT, we compared the outcomes of patients treated with DAPT or aspirin alone after TAVI.Methods and Results:We analyzed a total of 144 consecutive patients (92 females, mean age 83±6 years) who underwent implantation of a balloon-expandable transcatheter valve (SAPIEN or SAPIEN XT, Edwards Lifesciences)...

AIMS: While TAVI is the treatment of choice in patients with aortic stenosis considered inoperable or at high risk, interventional replacement of the mitral valve is still in the preclinical or early clinical phase. Our aim was to report on the first transcatheter double valve replacement into native valves from a transapical access. METHODS AND RESULTS: A 67-year-old, highly symptomatic female patient considered inoperable due to severe calcification of the mitral annulus and comorbidities was scheduled for transcatheter double valve replacement by the local Heart Team...

Severe device landing zone calcification (DLZ-CA) predicted paravalvular leak (PVL) and post-dilatation (PD) after transcatheter aortic valve implantation (TAVI). The aim of this study was to determine the influence of DLZ-CA on PVL or PD rates after SAPIEN XT (XT) versus CoreValve (CV).We analyzed patients undergoing TAVI who had severe DLZ-CA. Severe DLZ-CA defined the upper left ventricular outflow tract calcification; the cross-sectional region 2 mm inferior to the annular plane. PVL was evaluated at 30days using transthoracic echocardiography...

INTRODUCTION: Aortic stenosis (AS) is more than only a degenerative disease, it could be also an atherosclerotic-like process involving the valve instead of the vessels. Little is known about the relation of arterial stiffness and AS. AIM: We sought to determine wether pulse wave velocity (PWV), is related to AS severity and to the procedures response, both as surgical aortic-valve-replacement (AVR) and trascatheter-aortic-valve-implantation (TAVI). METHODS: 30 patients with severe AS were treated (15 AVR, 15 TAVI)...

BACKGROUND: Severe aortic stenosis (AS) is a common, serious valve disease in which no effective medical therapy is available and, if not treated by intervention, has a 5-year survival of only 40-60%. Despite the availability of guidelines supporting the effective use of surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI) to treat the majority of these patients, adherence to these guidelines in clinical practice is still unsatisfactory. Several recent studies have emphasised the necessity for improved communication between multidisciplinary teams, with the aim to ensure that severe AS patients receive appropriate treatment...
