OBJECTIVES: This study aims to establish parameters for identifying normal function for each of the 3 iterations of balloon-expandable valves and 2 iterations of self-expanding valves. BACKGROUND: Expected transthoracic echocardiographic Doppler-derived hemodynamic data for transcatheter aortic valves inform pre-implant decision-making and post-implanted monitoring of longitudinal valve function. METHODS: We collected the Echocardiography Core Lab measured mean gradients and effective orifice area (EOA) from discharge or 30-day echocardiograms from randomized trials; the PARTNER (Placement of Aortic Transcatheter Valves) trials for the balloon-expandable valves and the Medtronic CoreValve US Pivotal trial and Medtronic CoreValve Evolut R United States IDE Clinical Study for the self-expanding valves...

A 77 year old male underwent elective bioprosthetic aortic valve replacement (23mm Carpentier-Edwards Perimount MagnaEase) for severe aortic stenosis. His pre-discharge transthoracic echocardiogram (TTE) was normal. He presented 9 days after surgery with dyspnoea and fever. He was in sinus rhythm. Blood cultures were taken and he was commenced on empirical antibiotics for possible infective endocarditis (subsequently all negative). Repeat TTE showed a well-seated prosthesis without regurgitation but elevated gradients (peak / mean gradients 49 / 22 mmHg respectively)...

The indications for catheter-based structural and electrophysiological procedures have recently expanded to more complex scenarios, in which an accurate definition of the variable individual cardiac anatomy is key to obtain optimal results. Intracardiac echocardiography (ICE) is a unique imaging modality able to provide high-resolution real-time visualization of cardiac structures, continuous monitoring of catheter location within the heart, and early recognition of procedural complications, such as pericardial effusion or thrombus formation...

An 87-year-old woman presented to the emergency department with a 2-week history of progressively worsening shortness of breath, fever and generalised myalgia. She underwent a transcatheter Portico aortic valve implantation for severe symptomatic aortic stenosis 3 months prior to this presentation. Examination revealed a temperature of 40°C and a systolic murmur in the aortic area. Inflammatory markers were elevated, and blood cultures were positive for methicillin-sensitive Staphylococcus aureus A possible diagnosis of infective endocarditis was made as one major and one minor criterion in the modified Duke criteria were fulfilled...

Background: Anderson-Fabry disease is an X-linked inherited disease, which manifests in a different manner depending on gender and genotype. Making a working diagnosis of Anderson-Fabry disease is difficult because of several reasons: (a) that it is a multiorgan disease with wide variety of phenotypes, (b) different timelines of presentation, (c) gender differences, and (d) possible coexistence with other comorbidities. Late-onset/cardiac type of presentation with minimal involvement of other organs can additionally make diagnosis difficult...

The optimal periprocedural imaging strategy during transcathether aortic valve replacement (TAVR) performed under moderate sedation is debated. Transthoracic echocardiography (TTE) provides suboptimal views due to poorer resolution and patient positioning, whereas use of transesophageal echocardiography (TEE) under moderate sedation is not widely utilized. The aim of our study was to compare the value of TTE in comparison with TEE guidance under moderate sedation during TAVR. The study population included 144 consecutive patients (mean age 83±11 years, 78(54%) females) who had TAVR under moderate sedation using either a TTE (n=96) or TEE (n=48)...

OBJECTIVES: Temporally quantify and localize paravalvular aortic leak (PVL) after transcatheter aortic valve replacement (TAVR) in the Medtronic CoreValve (MCV) versus the Edwards Sapien Valve (ESV). BACKGROUND: In order to increase the precision of THV selection and PVL intervention, an understanding of PVL characteristics is essential. METHODS: The frequency, severity, and location of post-TAVR PVL were evaluated with transthoracic echocardiography pre-discharge, one month, and one-year post-procedure in 202 patients receiving a MCV (N = 120) or ESV (N = 81)...

About 60% of patients with paradoxical low-flow, low-gradient (PLF-LG) aortic stenosis (AS) have a severe disease that justifies aortic valve replacement (AVR). The first step in patients with symptomatic PLF AS should be to rule out measurement errors and treat hypertension. The second step is to distinguish pseudo-severe from true severe AS (TSAS). The third step is to select the optimal treatment modality at the right time. Regarding the second step, projected aortic valve area calculated using stress echocardiography is superior to traditional severity criteria (AVA < 1...

BACKGROUND: Functional impairment of the aorta is a recognized complication of aortic and aortic valve disease. Aortic strain measurement provides effective quantification of mechanical aortic function, and 3-dimenional (3D) approaches may be desirable for serial evaluation. Computerized tomographic angiography (CTA) is routinely performed for various clinical indications, and offers the unique potential to study 3D aortic deformation. We sought to investigate the feasibility of performing 3D aortic strain analysis in a candidate population of patients undergoing transcatheter aortic valve replacement (TAVR)...

OBJECTIVE: Transcatheter aortic valve replacement (TAVR) reduces left ventricular (LV) afterload and improves prognosis in aortic stenosis (AS) patients. However, LV afterload consists of both valvular and arterial loads, and the benefits of TAVR may be attenuated if the arterial load dominates. We proposed a new hemodynamic index, the Relative Valve Load (RVL), a ratio of mean gradient (MG) and valvuloarterial impedance (Zva), to describe the relative contribution of the valvular load to the global LV load, and examined whether RVL predicted patient outcome following TAVR...

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...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is a minimally invasive approach to aortic valve replacement. However, critical cardiovascular collapse can occur during the procedure for various reasons. CASE PRESENTATION: A 90-year-old man with severe aortic stenosis and left circumflex artery stenosis developed acute torrential mitral regurgitation (MR) during TAVR. The valve deployment process induced left ventricular dyssynchrony due to left bundle-branch block and myocardial ischemia in the left circumflex artery region with torrential MR...
