Wild-type transthyretin cardiac amyloidosis (ATTRwt-CA) occurs at a high prevalence in older patients with left ventricular (LV) hypertrophy. However, detecting ATTRwt-CA using echocardiography is challenging. This study identified echocardiographic findings characterizing compared monoclonal immunoglobulin light chain (CA) and hereditary CA. We conducted multicenter, retrospective on the ATTRwt-CA. J-CASE (Japan Cardiac Amyloidosis Survey of typical Echocardiographic findings) analyzed data...
Background: Cardiac power output is a measure of cardiac performance, and its prognostic significance has been shown in heart failure (HF) with reduced ejection fraction. Patients HF preserved fraction may have altered but the relevance unknown. This study sought to determine association between clinical outcomes compare effect other measures performance including ventricular-arterial coupling mechanical efficiency. Methods: normalized left ventricular mass was assessed by echocardiography...
2 JCS/JSCVS/JCC/CVIT 2023 Guideline Focused Update on Indication and Operation of PCPS/ECMO/IMPELLA individual facilities.Therefore, in this Focus Update, specific classes or levels evidence are not strictly mandatory, but rather they presented as expert consensus.However, we strongly hope that will (1) serve a guideline for the standardization PCPS, ECMO, IMPELLA therapy within Japan, (2) be widely used by various healthcare professionals including physicians, nurses, clinical engineers,...
Abstract Aims Higher left ventricular (LV) ejection fraction (EF) is related to unfavourable prognosis in patients with heart failure (HF) preserved (HFpEF). The cause of this finding needs be haemodynamically explained. Thus, we investigated crucial issue from the perspective LV–arterial (A) and right (RV)–pulmonary arterial (PA) coupling. Methods results Study were derived our prospective cohort study hospitalized due acute decompensated HF LVEF > 40%. We divided 255 into three...
Background: Adaptive servo-ventilation (ASV) improves cardiac function in patients with heart failure (HF). We compared the hemodynamics of control and HF patients, identified predictors for acute effects ASV HF. Methods Results: performed baseline echocardiographic measurements hemodynamic at after 15min during catheterization 11 34 patients. Heart rate blood pressure did not change either or group. Stroke volume index (SVI) decreased from 49.3±7.6 to 41.3±7.6ml/m2 controls (P<0.0001) but...
Background:Speckle-tracking echocardiography (STE)-derived parameters may have better correlation with left ventricular (LV) relaxation and filling pressure than tissue Doppler-derived parameters. However, it has not been elucidated which parameter – strain or rate direction of myocardial deformation longitudinal circumferential is the most useful marker LV pressure.Methods Results:We conducted a prospective multicenter study compared Doppler- STE-derived time constant decay (τ) mean...
Heart failure (HF) causes organ congestion, which is thought to increase stiffness. The virtual touch quantification (VTQ) method can be used assess liver stiffness in patients with chronic diseases. This study aimed measure and kidney using VTQ determine its value for assessing congestion HF.This included 10 normal subjects 38 HF (age 52.3±16.7 years, left ventricular ejection fraction 27.0±9.4%, plasma B-type natriuretic peptide [BNP] 1,297.3±1,155.1 pg/ml). We investigated the...

Abstract Introduction Accurate assessment of the left ventricular (LV) filling pressure in patients with atrial fibrillation (AF) remains difficult. Novel echocardiographic scoring system, visually assessed time difference between mitral valve (MV) and tricuspid (TV) opening (VMT) score based on visual sequence early-diastolic atrioventricular valves opening, is expected to be applied for these patients. Purpose This study aimed test diagnostic accuracy VMT AF. Methods We analyzed 119...
Abstract Introduction Assessment of right ventricular systolic function plays an important role in management cardiovascular disease. Tricuspid annular plane excursion (TAPSE) is the most widely used quantitative parameter; however, there a lack evidence regarding appropriate cut for its measurement. Purpose This study aimed to elucidate optimal TAPSE measurement, focusing on incidence angle M-mode cursor and relationship angle-independent parameter. Methods retrospective included 113 adult...
Background:Although longitudinal strain (LS) is known to be reduced in patients with hypertrophic cardiomyopathy (HCM), it has not been elucidated whether or circumferential (CS) reduced. We aimed determine multidirectional and layer-specific myocardial nonobstructive HCM.Methods Results:Speckle-tracking echocardiography was performed 41 HCM 27 control subjects. Segmental global LS CS were measured the inner, mid, outer layers. Global significantly lower group than controls inner (−10.3±2.9...
This longitudinal study was performed to determine changes in echocardiography parameters association with various biomarker levels pregnancy/postpartum.Fifty-one healthy pregnant women underwent simultaneous determination of blood five biomarkers at each the first, second and third trimesters pregnancy, immediately postpartum within 1 week after childbirth approximately month postpartum. Data on 255 scans (five times per woman) were analysed.Left ventricular end-diastolic dimension, left...
Abstract Aims The prognostic implication of left ventricular outflow tract velocity time integral (LVOT‐VTI) on admission in hospitalized heart failure with preserved ejection fraction (HFpEF) patients has not been determined. We sought to investigate whether LVOT‐VTI is associated worse clinical outcomes HFpEF. Methods and results studied consecutive 214 HFpEF who had accessible data admission, from a prospective HFpEF‐specific multicentre registry. primary outcome interest was the...
Abstract Aims Right‐sided filling pressure is elevated in some patients with heart failure (HF) and preserved ejection fraction (HFpEF). We hypothesized that right atrial (RAP) would represent the cumulative burden of abnormalities left heart, pulmonary vasculature, heart. Methods results Echocardiography was performed 399 HFpEF. RAP estimated from inferior vena cava morphology its respiratory change [estimated (eRAP)], were divided according to eRAP (3 or ≥8 mmHg). Patients higher displayed...
Newly introduced drugs for heart failure (HF) have been reported to improve the prognosis of HF with preserved ejection fraction (HFpEF) in lower range left ventricular (LVEF). We hypothesized that a higher LVEF is related an unfavourable patients HFpEF.We tested this hypothesis by analysing data from prospective multicentre cohort study 255 admitted hospital due decompensated (LVEF > 40% at discharge). The primary endpoint was composite outcome all-cause death and readmission HF, secondary...
Pre- and post-procedural hemodynamic changes which could affect adverse outcomes in aortic stenosis (AS) patients who undergo transcatheter valve replacement (TAVR) have not been well investigated. Four-dimensional (4D) flow cardiovascular magnetic resonance (CMR) enables accurate analysis of blood dynamics such as velocity, pattern, wall shear stress (WSS), energy loss (EL). We sought to examine the with severe AS underwent TAVR.
