ABSTRACT Background Speckles tracking echocardiography imaging enables clinicians to detect subtle systolic dysfunction. The aim of the present study was elucidate differences in speckle echocardiographic findings between immunoglobulin light chain amyloid cardiomyopathy (AL‐CM) and transthyretin (TTR‐CM). Methods patients with a confirmed diagnosis cardiac amyloidosis through biopsy from March 2013 October 2022 were included. relative apical sparing index (RASI) calculated using by...
Abstract Background Manual interpretation of echocardiographic data is time-consuming and operator-dependent. With the advent artificial intelligence (AI), there a growing interest in its potential to streamline reduce variability. This study aimed compare time taken for measurements by AI that human experts after converting acquired dynamic images into DICOM data. Methods Twenty-three consecutive patients were examined single operator, with varying image quality different medical...
Importance The characteristics and treatment strategies of atrial functional mitral regurgitation (AFMR) are poorly understood. Objective To investigate the prevalence, clinical characteristics, outcomes valve (MV) surgery in AFMR. Design, Setting, Participants This retrospective cohort study, called Real-World Observational Study for Investigating Prevalence Therapeutic Options Atrial Functional Mitral Regurgitation (REVEAL-AFMR), was conducted across 26 Japanese centers (17 university...
Abstract Background Patients with severe aortic valve stenosis undergoing transcatheter replacement (TAVR) present a high prevalence of heart failure preserved ejection fraction (HFpEF). An elevated left atrial stiffness index (LASI) has recently been recognized as potential prognostic factor for worsened outcomes in HFpEF patients. Purpose This study investigates whether the LASI is following TAVR Methods In this single-center retrospective study, patients who underwent at our center from...
The aim of this study was to assess the role clinically available vascular function tests as predictors cardiovascular events and decline in kidney function.One hundred fourteen patients who had at least 2 risk factors were recruited for assessment including ankle-brachial blood pressure index (ABI), brachial-ankle pulse wave velocity (baPWV), cardio-ankle (CAVI) flow-mediated vasodilatation (%FMD). During a median period 51 months, 35 reached primary endpoint (29 6 cardiac deaths), 30...
Background Left atrial ( LA ) strain analysis using speckle tracking echocardiography is useful for assessing function. However, there no established procedure this method. Most investigators have determined the electrocardiographic R‐wave peak as starting point analysis. To test our hypothesis that P‐wave onset should be used point, we measured 2 different points and compared values with corresponding volume indices obtained by three‐dimensional (3D) echocardiography. Methods We enrolled 78...
Background Concurrent presence of aortic stenosis and regurgitation is termed mixed valve disease ( MAVD ). Although multiple articles have addressed patients with “isolated” or regurgitation, the natural history, impact, outcomes are not well defined. Here, we evaluate long‐term in cardiovascular adaptations to chronic . Methods Results This observational cohort study evaluated 862 adult (56.8% male) preserved left ventricular ejection fraction at least moderate stenosis. Primary outcome...
Obesity leads to an increased risk of cardiovascular disease morbidity and death, including heart failure. Bariatric surgery has been proven be the most effective long-term weight management treatment. This study investigated changes in cardiac structure function after bariatric surgery, left ventricular global longitudinal strain.
Abstract Aims Risk assessment of developing cardiac involvement in systemic sarcoidosis can be challenging because limited data. Recently, attention has been given to left ventricular and right (LV RV) (CS) its prevalence, relevance, prognostic value. The aim this study was assess the role biventricular strain predict prognosis confirmed patients. Methods results LV RV longitudinal strains (LSs) were evaluated by 2D speckle tracking 139 consecutive patients without other pre-existing...
High prevalence of frailty and diastolic dysfunction (DD) in heart failure high mortality frail adults have been noted. We characterized by quantifying differences on echocardiography, assessed the added prognostic utility DD grade an elderly population.One hundred ninety-one patients ≥65 years who had at least 1 cardiovascular risk factor were prospectively recruited for clinically indicated echocardiography present institute. Weight loss, exhaustion, deficits physical activity, gait speed,...
Background The management of mixed aortic valve disease (MAVD), defined as the concomitant presence stenosis (AS) and regurgitation, remains a clinical challenging. present study assessed impact transcatheter replacement (TAVR) on cardiac geometry prognosis in patients with MAVD. Methods Results A retrospective multicenter TAVR registry was conducted, including who underwent for severe symptomatic AS between January 2015 March 2019. Patients were subdivided into 2 groups according to...
Background— The projected aortic valve area (AVA proj ) at a normal transvalvular flow rate using dobutamine is helpful to determine the actual severity of stenosis (AS) and predict risk adverse events in low-gradient AS cases with unclear surgical indication. Our study aimed identify independent incremental value preload stress echocardiography-derived AVA outcomes patients preserved ejection fraction AS. Methods Results— We prospectively performed echocardiographic studies 79 (age, 77±7...
Objective The aim of our study was to assess the association between risk cancer-therapy-related cardiac dysfunction (CTRCD) after first follow-up and difference in echocardiographic measures from baseline follow-up. Methods We retrospectively enrolled 87 consecutive patients (58±14 years, 55 women) who received anthracycline underwent examinations both before (baseline) initial administration (first follow-up). measured absolute values global longitudinal strain (GLS), apical (LS), mid-LS...
We sought to assess the relationship between left atrial (LA) strain mechanics and exercise intolerance, evaluate prognostic impact of LA on clinical deterioration necessitating septal reduction therapy in hypertrophic cardiomyopathy (HCM).Consecutive HCM patients who underwent stress echocardiography cardiopulmonary testing same day October 2015 April 2019 were enrolled prospectively. analysed using speckle tracking echocardiography. stiffness was calculated as ratio E/e' reservoir strain....
