BACKGROUND: We aimed to assess the relationship between echocardiographic characteristics and mortality in patients with chronic obstructive pulmonary disease (COPD). METHODS: We prospectively studied 154 patients (mean age 71 ± 10 years, 71% male) with COPD. All patients underwent transthoracic Doppler echocardiography within 48 hours of hospital admission. Primary endpoint was all-cause mortality during a median period of 22 months. RESULTS: Mildly elevated tricuspid regurgitation pressure and mitral E/e' ratio were the most commonly encountered echocardiographic abnormalities, observed in 60% and 56% of patients, respectively...

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...

: Rivaroxaban, a selective inhibitor of active factor X belongs to the group of direct-acting oral anticoagulants (DOAC), more and more often replacing vitamin K antagonists (VKA) in venous thromboembolic disease and nonvalvular atrial fibrillation. Attempts are also being made to use DOAC to treat locally formed intracardiac thrombi, mainly in the left atrium and its appendage, in atrial fibrillation and in heart failure. Rarely diagnosed local right ventricular thrombus (RVT) may be a complication of dilated cardiomyopathy (DCM)...

BACKGROUND: -Although HF disproportionately affects older adults, little data exist regarding the prevalence of American College of Cardiology/American Heart Association heart failure (HF) stages among older individuals in the community. Additionally, the role of contemporary measures of longitudinal strain (LS) and diastolic dysfunction in defining HF stages is unclear. METHODS: -HF stages were classified in 6,118 participants in the Atherosclerosis Risk in Communities study (age 67 - 91 years) at the fifth study visit as follows: stage A (asymptomatic with HF risk factors but no cardiac structural or functional abnormalities), B (asymptomatic with structural abnormalities, defined as left ventricular hypertrophy, dilation or dysfunction, or significant valvular disease), C1 (clinical HF without prior hospitalization), and C2 (clinical HF with prior hospitalization)...

BACKGROUND: Chronic aortic regurgitation can be well tolerated for a long time. Some patients with normal ventricular function can even reach high levels of sporting performance. How the severity of regurgitation may change during exercise, however, is little known, although some studies suggest it diminishes. The present work examines, during exercise, the functional capacity, ventricular function, and regurgitation fraction (RF) in asymptomatic subjects with moderate or severe aortic regurgitation with preserved ejection fraction...

Because subclinical alterations in cardiovascular structure reflect cumulative damage induced by risk factors and represent an intermediate stage between risk factor exposure and cardiovascular events, this damage is regarded as a marker of increased cardiovascular risk in different clinical settings, including the general population. The Pressioni Monitorate e Loro Associazioni (PAMELA) is an originally designed research study aimed at assessing the normal values and prognostic significance of ambulatory and home blood pressure in a representative sample of the Northern Italian general population...

The aim of the present study was to confirm the effect of Tanshinone IIA (TAN) on the prevention of AF in chronic heart failure (CHF), and to elucidate the underlying electrophysiological mechanisms for the antiarrhythmic effects of TAN at the level of the atrium in an experimental model of CHF. In 10 female rabbits, CHF was induced by rapid ventricular pacing, leading to a significant decrease in ejection fraction in the presence of a dilated left ventricle and atrial enlargement. Twelve rabbits were sham-operated and served as controls...

BACKGROUND: Segmental and global mitral valve prolapse (MVP) comprise 2 representative phenotypes in this syndrome. While mitral regurgitation (MR) severity is a major factor causing left atrial (LA) remodeling in MVP, prominent mitral valve (MV) annulus dilatation in global MVP may specifically cause inferiorly predominant LA remodeling. We compared MV annulus and LA geometry in patients with segmental and global MVP.Methods and Results:LA volume as well as inferior, middle, and superior LA cross-sectional areas (CSA) were measured on 3-D echocardiography in 20 controls, in 40 patients with segmental MVP, and in 18 with global MVP...

Marfan syndrome (MFS) is an autosomal-dominant disorder of connective tissue caused by mutations in the fibrillin-1 (FBN1) gene. Mortality is often due to aortic dissection and rupture. We investigated the structural and functional properties of the heart and aorta in a [Fbn1C1039G/+] MFS mouse using high-resolution ultrasound (echo) and optical coherence tomography (OCT). Echo was performed on 6- and 12-month old wild type (WT) and MFS mice (n = 8). In vivo pulse wave velocity (PWV), aortic root diameter, ejection fraction, stroke volume, left ventricular (LV) wall thickness, LV mass and mitral valve early and atrial velocities (E/A) ratio were measured by high resolution echocardiography...

The left atrium plays an important role in the maintenance of cardiovascular and neurohumoral homeostasis in heart failure. However, with progressive left ventricular dysfunction, left atrial (LA) dilation and mechanical failure develop, which frequently culminate in atrial fibrillation. Moreover, LA mechanical failure is accompanied by LA endocrine failure [deficient atrial natriuretic peptide (ANP) processing-synthesis/development of ANP resistance) and LA regulatory failure (dominance of sympathetic nervous system excitatory mechanisms, excessive vasopressin release) contributing to neurohumoral overactivity, vasoconstriction, and volume overload (global LA failure)...

OBJECTIVES: The purpose of our study is to verify, whether percutaneous mitral annuloplasty results in reverse remodeling in patients with functional mitral regurgitation (FMR) and impaired ejection fraction (EF) and to investigate which echo parameters may help in prediction of the efficacy of the procedure. BACKGROUND: FMR exacerbates left ventricular (LV) dilatation and contributes to both LV remodeling and heart failure. METHODS: We analyzed baseline and 1 month follow-up data in 22 consecutive patients with FMR, who underwent successful percutaneous trans-coronary venous mitral annuloplasty with the Carillon device...

BACKGROUND: Detection of atrial fibrillation after ischemic stroke is challenging due to its paroxysmal nature. We aimed to assess predictors of paroxysmal atrial fibrillation using non-invasive surface ECG and transthoracic echocardiography to select candidates for atrial fibrillation screening. METHODS: Ischemic stroke patients without documented atrial fibrillation (n = 110, 67 ± 10 years, 40 female) and a control group of age- and gender-matched patients with history of paroxysmal atrial fibrillation prior to stroke (n = 55, 67 ± 10 years, 19 female) comprised the study sample...

Heart transplant is the only definitive treatment of end-stage heart failure. Venoarterial extracorporeal membrane oxygenation may be used as a bridge to heart transplant. Among 31 patients who underwent heart transplant between January 2014 and June 2016, we present our experiences with 3 patients who received venoarterial extracorporeal support as a bridge to heart transplant. The first patient was a 51-year-old male with ischemic dilated cardiomyopathy. Transplant was performed after 6 days of extracorporeal support, and the patient was discharged and alive at follow-up...

Left atrial (LA) dilation has been shown to be associated with atrial fibrillation (AF) in the adult population, with some studies indicating that larger LAs are more prone to AF recurrence. The relation of LA size to AF in the pediatric and young adult population has not been investigated. In this study, all pediatric patients (aged ≤22 years) who presented to Boston Children's Hospital from January 2002 to December 2012 with AF were reviewed. Patients with significant congenital heart disease, cardiomyopathies, proven channelopathies, previous cardiac surgery, end-stage renal disease, or severe lung disease/cystic fibrosis were excluded...

Radiosurgery to the pulmonary vein antrum in the left atrium (LA) has recently been proposed for non-invasive treatment of atrial fibrillation (AF). Precise real-time target localization during treatment is necessary due to complex respiratory and cardiac motion and high radiation doses. To determine the 3D position of the LA for motion compensation during radiosurgery, a tracking method based on orthogonal real-time MRI planes was developed for AF treatments with an MRI-guided radiotherapy system. Four healthy volunteers underwent cardiac MRI of the LA...
