OBJECTIVE: This study sought to analyze outcomes in patients with moderate-severe tricuspid regurgitation (TR) undergoing transcatheter aortic valve replacement (TAVR). The consequences of uncorrected significant TR in patients undergoing TAVR remain undefined. METHODS: Between 2009 and 2014, 369 patients underwent TAVR at our institution, and 58 of these had baseline moderate-severe TR. Preoperative, 30-day, and 1-year transthoracic echocardiograms were analyzed...

OBJECTIVES: Left atrial appendage thrombus (LAT) was an exclusion criterion in the seminal transcatheter aortic valve replacement (TAVR) trials; however, such patients do undergo TAVR in the 'real-world' setting. This study sought to analyse outcomes after TAVR in patients with LAT or spontaneous echo contrast (SEC). METHODS: All patients undergoing TAVR at our institution between March 2009 and December 2014 were prospectively analysed. The presence of LAT or SEC was determined via a retrospective chart review...

Aims: In patients randomized to transcatheter or surgical aortic valve replacement (TAVR, SAVR), we sought to determine whether SAVR is associated with worsening right ventricular (RV) function and whether RV deterioration is associated with mortality. Methods and results: In 1376 patients from PARTNERIIA with paired baseline and 30-day core lab echocardiograms, worsening RV function was defined as decline by at least one grade from baseline to 30 days. Our primary outcome was all-cause mortality from 30 days to 2 years...

BACKGROUND: Eccentric valve deployment after transcatheter aortic valve replacement (TAVR) has been associated with abnormal leaflet shear stresses that may accelerate structural valve deterioration (SVD). This phenomenon has not been studied in patients receiving Sapien 3 prostheses (Edwards Lifesciences). METHODS: A retrospective cohort analysis of 100 patients who received Sapien 3 valves between 2013 and 2015 at a single institution was performed. Axial fluoroscopic images from the co-planar view were used to assess TAVR asymmetry, which was defined as a ratio of left-to-right valve heights ≤0...

BACKGROUND: Global longitudinal strain (GLS) has incremental value in assessing left ventricular (LV) function in severe aortic stenosis and is related to clinical outcome after transcatheter aortic valve replacement (TAVR). We sought to identify relevant echocardiographic predictors of GLS improvement and myocardial function recovery after TAVR. METHODS: We analyzed baseline and 12-month follow-up echocardiograms for LV strain analysis from 123 patients who underwent at Emory University Hospital with the Edwards SAPIEN valve between 7/2007 and 7/2013...

An 88-year-old woman with a prior history of aortic stenosis and history of valvuloplasty presented with worsening symptoms of heart failure and dizziness. She underwent successful transcatheter aortic valve replacement (TAVR) without complications. Follow-up echocardiograms revealed a small fistula connecting aorta to the right ventricle. The patient was initially asymptomatic but 3 months later developed overload of the right ventricle and heart failure and chose to continue medical therapy. She died of progressive heart failure at 9 months from onset of fistula...

BACKGROUND: Recent reports of leaflet abnormalities (detected using advanced imaging) have raised questions regarding transcatheter aortic valve replacement (TAVR) durability. We sought to determine the incidence of valve hemodynamic deterioration (VHD) and its association with cardiovascular outcomes. METHODS AND RESULTS: Consecutive cases with paired postimplant and follow-up echocardiograms from November 2011 to March 2015 in the STS/ACC TVT Registry were allocated into 2 overlapping cohorts: early (paired echocardiograms at 0 and 30 days) and late (paired echocardiograms at 30 days and 1 year)...

An 87-year-old female with symptomatic severe aortic stenosis underwent transcatheter valve replacement (TAVR) via the transfemoral approach with a 29mm self-expanding device. Moderate to severe paravalvular regurgitation led to the development of congestive heart failure and hospital readmission 1 month following TAVR. A second 29mm valve was placed to abolish the paravalvular regurgitation. Routine follow-up computed tomography (CT) imaging demonstrated leaflet thickening and decreased leaflet mobility suggesting valve thrombosis, despite adherence to Factor Xa inhibitor...

OBJECTIVES: To describe patients with severe symptomatic aortic stenosis with normal flow and low gradients and determine whether they benefit from intervention. BACKGROUND: Severe symptomatic aortic stenosis is a progressive disease with high mortality. Although surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR) are indicated for patients with high gradients (>40 mm Hg) or low gradients due to low flow, the approach for patients with normal flow and low gradients is poorly defined...

Background: Transcatheter aortic valve replacement (TAVR) has been shown safe and feasible in patients with bicuspid aortic valve (BAV) morphology. Evaluation of inter-ethnic differences in valve morphology and function and aortic root dimensions in patients with BAV is important for the worldwide spread of this therapy in this subgroup of patients. Comparisons between large European and Asian cohorts of patients with BAV have not been performed, and potential differences between populations may have important implications for TAVR...

In the United States, valvular heart disease (VHD) has a prevalence of 2.5%, most commonly presenting as aortic stenosis (AS) or mitral valve regurgitation (MR) and increasingly observed to be of a degenerative etiology. Women frequently have latent symptoms despite significant disease, and it is therefore pertinent to consider both clinical symptoms and imaging findings for decision-making on treatment. Indeed, significant advances have been made in noninvasive imaging allowing for more accurate diagnosis and disease prognostication...

Transcatheter aortic valve replacement (TAVR) has revolutionized the treatment of symptomatic aortic stenosis. The number of TAVR procedures is expected to increase exponentially in the next decade. Therefore, patients will inevitably present with signs and symptoms attributable to TAVR bioprosthesis failure many years after an acutely successful procedure. Their management will become increasing important moving forward. Areas covered: The aim of this article is to review the causes of bioprosthesis failure and outline optimal management strategies in elderly patients...

Echocardiography is the cornerstone in the diagnosis of any valvular heart disease. The accurate diagnosis of aortic stenosis, the left ventricle function and the other heart valves evaluation are currently done by ultrasound alone. Prosthetic valve choice and dimensions prior to implantation can be done solely by proper use of echocardiography. The emergence of new methods to cure aortic stenosis such as trans-catheter aortic valve replacement (TAVR) emphasized the diagnostic value of cardiac ultrasound. The usefulness of echocardiography in TAVR can be divided in the baseline assessment (common to patients treated by conventional surgery), intra-procedural guidance of valve deployment and post-procedural follow-up...
