Bioprosthetic valve thrombosis is associated with accelerated bioprosthesis degeneration and valve re-replacement. Whether 3-month warfarin use after transcatheter aortic valve implantation (TAVI) protects against such consequences is unknown. We aimed to investigate if 3-month warfarin treatment after TAVI is associated with better outcomes than dual antiplatelet therapy (DAPT) and single antiplatelet therapy (SAPT) at medium-term follow-up. Adults who underwent TAVI were identified retrospectively (n = 1,501) and classified into warfarin, DAPT, and SAPT groups based on antithrombotic regimen received...

BACKGROUND: Surgical management of isolated tricuspid regurgitation (TR) is associated with high morbidity and mortality, thereby creating a significant need for a lower-risk transcatheter solution. OBJECTIVES: The single-arm, multicenter, prospective CLASP TR (Edwards PASCAL TrAnScatheter Valve RePair System in Tricuspid Regurgitation [CLASP TR] Early Feasibility Study) evaluated 1-year outcomes of the PASCAL transcatheter valve repair system (Edwards Lifesciences) to treat TR...

AIMS: Tricuspid valve regurgitation (TR) is a common valvular disease associated with increased mortality. There is a need for tools to assess the interaction between the pulmonary artery (PA) circulation and the right ventricle in patients with TR and to investigate their association with outcomes. The pulmonary artery pulsatility index (PAPi) has emerged as a haemodynamic risk predictor in left heart disease and pulmonary hypertension (PH). Whether PAPi discriminates risk in unselected patients with greater than or equal to moderate TR is unknown...

We present the first case of cardiac implantable electronic device (CIED) infection due to Neisseria cinerea in a 64-year-old woman from Panama. She had a history of splenectomy, aortic valve stenosis requiring transcatheter aortic valve replacement (TAVR), and permanent pacemaker placement. She presented with relapsing N. cinerea bacteremia over a 3-month period. Transesophageal echocardiography revealed a lead vegetation in the superior vena cava. She was successfully treated with pacemaker removal and 2 weeks of IV antibiotic therapy...

Background Description of cerebral and retinal infarction in patients with bicuspid aortic valve (BAV) is limited to case reports. We aimed to characterize cerebral and retinal infarction and examine outcomes in patients with BAV. Methods and Results Consecutive patients from 1975 to 2015 with BAV (n=5401) were retrospectively identified from the institutional database; those with confirmed cerebral or retinal infarction were analyzed. Infarction occurring after aortic valve replacement was not included. Patients were grouped according to infarction pathogenesis: embolism from a degenerative calcific BAV (BAVi); non-BAV, large artery atherosclerotic or lacunar infarction (LAi); and non-BAV, non-large artery embolic infarction (nLAi)...

BACKGROUND: The recent morphologic classification of tricuspid regurgitation (TR) (ie, atrial functional, ventricular functional, lead related, and primary) does not capture underlying comorbidities and clinical characteristics. OBJECTIVES: This study aimed to identify the different phenotypes of TR using unsupervised cluster analysis and to determine whether differences in clinical outcomes were associated with these phenotypes. METHODS: We included 13,611 patients with ≥moderate TR from January 2004 to April 2019 in the final analyses...

In patients undergoing aortic valve surgery, preoperative reduced left ventricular ejection fraction is not uncommon and is associated with poor outcomes. Mechanical circulatory support (MCS) may be preemptively used in patients presenting with high periprocedural risk. The Impella 5.5 is a percutaneous left ventricular assist device that has been increasingly used in various cardiac surgeries. In this article, we present a step-by-step guide, safeguards, and pitfalls on how to replace the aortic valve and preserve this transaortic MCS device for postoperative support in patients with concomitant aortic valve pathology and left ventricular dysfunction...

OBJECTIVES: Low forced expiratory volume in 1 second (FEV1) and elevated N-terminal Pro form B-type natriuretic peptide (NT-Pro-BNP) have been individually associated with poor outcomes after transcatheter aortic valve replacement (TAVR). We hypothesized a combination of the two would provide prognostic indication after TAVR. METHODS: We categorized 871 patients who received TAVR from 2008 to 2018 into 4 groups according to baseline FEV1 (< or ≥ 60% predicted) and NT-Pro-BNP (< or ≥ 1601 pg/ml): group A (n = 312, high FEV1, low NT-Pro-BNP), group B (n = 275, high FEV1, high NT-Pro-BNP), group C (n = 123 low FEV1, low NT-Pro-BNP), and group D (n = 161, low FEV1, high NT-Pro-BNP)...

AIMS: Aortic stenosis (AS) induces characteristic changes in left ventricular (LV) mechanics that can be reversed after aortic valve replacement (AVR). We aimed to comprehensively characterize LV mechanics before and after AVR in patients with severe AS and identify predictors of short-term functional recovery and long-term survival. METHODS AND RESULTS: We prospectively performed comprehensive strain analysis by 2D speckle-tracking echocardiography in 88 patients with severe AS and LV ejection fraction ≥50% (mean age 71 ± 12 years, 42% female) prior to and within 7 days after AVR...

The prevalence and impact of atrial fibrillation (AF) versus sinus rhythm (SR) on outcomes in very severe aortic stenosis (vsAS) of the native valve is unknown. The aim of the study was to determine the prognostic significance of AF in vsAS. A total of 563 patients with vsAS (transaortic valve peak velocity ≥5 m/s) and left ventricular ejection fraction ≥50% were identified retrospectively. Patients were divided by rhythm at the time of index transthoracic echocardiogram (AF: n = 50 [9%] vs SR: n = 513 [91%])...

BACKGROUND: Atrial fibrillation (AF) is considered a risk factor for isolated tricuspid valve regurgitation (TR) in the absence of other known etiologies. OBJECTIVES: This study sought to identify the incidence of clinically significant isolated TR and its impact in patients with AF. METHODS: A population-based record linkage system was used to identify adult patients with new-onset AF. Patients with evidence of moderate or greater tricuspid valve disease, left-sided valve disease, pulmonary hypertension, prior cardiac surgery, impaired left ventricular systolic/diastolic function at baseline were excluded...

This review discusses recent advancements in the field of valvular heart disease. Topics covered include recognition of the impact of atrial fibrillation on development and assessment of valvular disease, strategies for global prevention of rheumatic heart disease, understanding and management of secondary mitral regurgitation, the updated classification of bicuspid aortic valve disease, recognition of heightened cardiovascular risk associated with moderate aortic stenosis, and a growing armamentarium of transcatheter therapies...

BACKGROUND: Doppler mean gradient (MG) can underestimate aortic stenosis (AS) severity when obtained during atrial fibrillation (AF) compared with sinus rhythm (SR). Aortic valve weight (AVW) is a flow-independent measure of AS severity. The objective of this study was to determine whether AVW or AVW/MG ratio was increased in AF versus SR in patients with AS. METHODS: Excised native aortic valves from 495 consecutive patients (median age, 77 years; interquartile range [IQR], 71-82 years; 40% women), with left ventricular ejection fractions ≥50% who underwent surgical aortic valve replacement for native valve severe AS (aortic valve area ≤ 1 cm2 or indexed aortic valve area ≤ 0...

BACKGROUND: Tricuspid regurgitation (TR) is prevalent and undertreated, with mortality and morbidity increasing with TR severity. Given poor outcomes with medical therapy and high in-hospital mortality for isolated tricuspid valve surgery, emerging transcatheter repair devices offer a promising alternative. OBJECTIVES: The Edwards Cardioband Tricuspid Valve Reconstruction System Early Feasibility study (NCT03382457) evaluates the treatment of functional TR via annular reduction with the Cardioband Tricuspid Valve Reconstruction System (Edwards Lifesciences)...

BACKGROUND: There are limited data on the predictors of death or heart failure hospitalization (HFH) in patients with heart failure (HF) with functional mitral regurgitation (FMR). OBJECTIVES: The aim of this study was to develop a predictive risk score using the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients With Functional Mitral Regurgitation) trial database. METHODS: In COAPT, 614 symptomatic patients with HF and moderate to severe or severe FMR were randomized to MitraClip implantation plus guideline-directed medical therapy (GDMT) or GDMT alone...

BACKGROUND: Current bioprostheses are considered to have improved durability and better hemodynamic performance compared with previous designs, but there are limited comparative data on late outcomes. METHODS: From 2009 through 2011, 300 adults with severe aortic valve stenosis undergoing aortic valve replacement (AVR) were randomly assigned to receive Edwards Magna, St Jude Epic, or Sorin Mitroflow bioprostheses (n = 100, n = 101, n = 99, respectively)...
