BACKGROUND: Papillary fibroelastomas are rare, benign cardiac tumors that are often found on cardiac valvular surfaces. Most are incidental discoveries during surgery or autopsy. The clinical presentation of fibroelastoma varies widely, ranging from clinically asymptomatic to severe thromboembolic events. CASE PRESENTATION: We report a case of 65-year-old white man diagnosed with scattered, bilateral acute cerebral hemisphere infarcts with a history of chronic angina...

BACKGROUND: The prognostic value of N-terminal fragment of pro B-type natriuretic peptide (Nt-proBNP) in aortic stenosis (AS) is still being debated. We sought to evaluate the determinants of Nt-proBNP in AS and its prognostic value in asymptomatic patients. METHODS: Patients with pure isolated at least mild degenerative AS enrolled in our prospective cohort (2006-2013) constituted our population. Clinical and biological measurements as well as echocardiographic evaluations were performed at study entry for all patients...

BACKGROUND: We aimed to identify the clinical and echocardiographic determinants of symptoms and their prognostic implications in patients with moderately dysfunctional bicuspid aortic valves (BAVs). METHODS: Among 1,019 subjects in the BAV registry treated in a single tertiary care center, the records of 127 patients (85 men, age 58±13 years) with moderately dysfunctional BAVs were comprehensively reviewed. The patients were divided into two groups based on symptom status: asymptomatic (n = 80) vs...

Transcatheter aortic valve replacement (TAVR) is an effective, nonsurgical treatment option for patients with severe aortic stenosis. The optimal treatment strategy for treating concomitant coronary artery disease (CAD) has not been tested prospectively in a randomized clinical trial. Nevertheless, it is standard practice in the United States to perform coronary angiography and percutaneous coronary intervention for significant CAD at least 1 month before TAVR. All existing clinical trials were designed using this strategy...

BACKGROUND: There remains much controversy on impact of preoperative coronary artery disease (CAD) and necessity of preoperative coronary revascularization on postoperative outcomes in patients undergoing transcatheter aortic valve replacement (TAVR). METHODS: Data were collected retrospectively for 364 consecutive patients undergoing TAVR at Newark Beth Israel Medical Center, New Jersey, from May 15, 2012 to September 17, 2015. Preoperative CAD burden was calculated by three different measures of CAD: SYNTAX score, Duke Myocardial Jeopardy score (DMJS), and number of diseased coronary arteries...

BACKGROUND: Objective assessment of maximal aerobic capacity using peak oxygen consumption (peak VO2) can be helpful in the management of patients with asymptomatic aortic stenosis (AS). The relationship between peak VO2 and AS severity criteria derived from rest and supine exercise echocardiography (SEE) has never been explored. OBJECTIVES: We aimed to determine whether low peak VO2 (<85% of predicted value) is associated with severity parameters in SEE, and poor clinical outcome...

BACKGROUND: Current guidelines define severe aortic stenosis in patients with aortic valve area normalized to body surface area (AVA/BSA) <0.6 cm(2)/m(2); yet, this cutoff has never been validated. Moreover, it is not known whether AVA normalization to other body size indexes allows improved outcome prediction. We aim to test the value of AVA normalized to body size for outcome prediction in asymptomatic aortic stenosis. METHODS AND RESULTS: We included 289 patients with asymptomatic aortic stenosis, preserved ejection fraction, and AVA<1...

BACKGROUND: Transition from an asymptomatic to symptomatic state in severe aortic stenosis is often difficult to assess. Identification of a morphological sign of increased hemodynamic load may be important in asymptomatic aortic stenosis to identify patients at risk. METHODS AND RESULTS: Thirty-nine patients with asymptomatic severe aortic stenosis (aortic valve area <1 cm(2), peak jet velocity >3.5 m/s) underwent exercise testing with simultaneous invasive hemodynamic monitoring and Doppler echocardiography...

INTRODUCTION: Tissue Doppler imaging (TDI) and N-terminal-pro-Brain Natriuretic Peptide (NT-proBNP) provides useful non-invasive information about left ventricle filling pressures and both have demonstrated to be a prognostic marker in some valve disease as aortic stenosis (AS). OBJECTIVES: To assess the clinical value of combined TDI and NT-proBNP information in asymptomatic AS patients. MATERIAL AND METHODS: Prospective study of 350 initially asymptomatic moderate to severe AS patients with: Mean aortic valve area 0...

BACKGROUND: The ACC/AHA guidelines introduced a new classification of severe aortic stenosis (AS) mainly based on maximum jet velocity (Vmax) and mean pressure gradient (mPG), but not on aortic valve area (AVA). However, prognostic value of this new classification has not yet been fully evaluated. METHODS AND RESULTS: We studied 1512 patients with asymptomatic severe AS enrolled in the CURRENT AS registry in whom surgery was not initially planned. Patients were divided into 2 groups: Group 1 (N=122) comprised patients who met the recommendation for surgery; high-gradient (HG)-AS (Vmax≥4...

BACKGROUND: Auckland City Hospital (ACH) established a Heart Murmur Clinic (HMC) with the aim of providing prompt assessment of patients with asymptomatic systolic murmurs. This may lead to early intervention and improved outcomes if significant structural heart disease is detected and reassurance if no significant findings found. Similar clinics for children have proven beneficial; the benefit of a HMC in an adult population has been difficult to determine. OBJECTIVES: To review the clinical demographics and echocardiographic information of patients presenting to our HMC and to assess what proportion had significant structural heart disease and determine the common structural abnormalities in this population...

Most young patients with mild-to-moderate aortic stenosis show no symptoms, and sudden death appears only occasionally. We hypothesised that malignant ventricular arrhythmias could be responsible for the high incidence of sudden death in such patients. If multiple factors such as asymptomatic aortic stenosis in association with arrhythmia-provoking agents are involved, could it be sufficient to account for sudden unexpected death? In this study, eight cases of sudden death in young adults, with ages ranging from 22 to 36 years, who had never reported any symptoms that could be related to aortic stenosis, were investigated...

OBJECTIVE: Intracranial arterial stenosis (ICAS) is a common cause of ischemic stroke in Asians, whereas whites tend to have more extracranial lesions. Lipoprotein-associated phospholipase A2 (Lp-PLA2) has been associated with ischemic stroke by a large amount of work. However, there are few studies focusing on the relationship of Lp-PLA2 and asymptomatic ICAS or extracranial arterial stenosis (ECAS). We hereby sought to explore the relationship of Lp-PLA2 and ICAS, ECAS and concurrent stenosis in stroke-free hypertensive patients in Chinese population...

BACKGROUND: Controversial results on maternal risk and fetal outcome have been reported in women with aortic stenosis (AS). OBJECTIVES: The authors sought to investigate maternal and fetal outcomes in patients with AS in a large cohort. METHODS: The Registry on Pregnancy and Cardiac Disease (ROPAC) is a global, prospective observational registry of women with structural heart disease, providing a uniquely large study population. Data of women with moderate (peak gradient 36 to 63 mm Hg) and severe AS (peak gradient ≥64 mm Hg) were analyzed...

BACKGROUND: The management of patients with asymptomatic severe aortic stenosis (ASAS) is still under discussion. Therefore, it is advisable to search for the parameters of early damage to left ventricular function. AIM: The aim of the study was to assess exercise-induced changes in left ventricular global longitudinal strain (GLS) in ASAS. METHODS: The ASAS group consisted of 50 patients (26W/24M, aged 38.4±18.1) meeting the echocardiographic criteria of severe aortic stenosis (AVA<1cm², AVAI<0...

PURPOSE: Valvuloarterial impedance (ZVA ), estimating left ventricle (LV) afterload, has been proposed in transthoracic echocardiography (TTE) as a predictor of mortality in aortic valve stenosis (AVS). However, its calculation differs from arterial characteristic impedance (ZC ). Our aim was to apply the concept of ZC calculation to estimate ZVA from MR with carotid tonometry and to evaluate these indices through their associations with symptoms, LV diastolic function and aortic stiffness...
