Transthoracic echocardiography (TTE) is widely used in clinics to evaluate left ventricular hypertrophy (LVH). However, TTE usually insufficient for the etiological diagnoses when morphological and functional features are nonspecific. With booming of computer science artificial intelligence (AI), previous literature has reported application radiomics based on cardiac magnetic resonance imaging, computed tomography diagnosing several myocardial abnormalities, such as infarction, myocarditis,...

<b><i>Background:</i></b> Heart failure may induce atrial dyssynchrony. We aim to investigate whether preimplantation left (LA) dyssynchrony could predict newly detected high-rate episodes (AHRE) after receiving cardiac resynchronization therapy defibrillator (CRT-D). <b><i>Methods:</i></b> conducted a retrospective analysis of consecutive patients who received CRT-D for standard indications and without history fibrillation. The deviation the...

Mini‐Abstract Right atrial appendage aneurysm ( RAAA ) is a rare malformation of the heart. Here, we present case in an elderly man, who has remained asymptomatic for over 10 months follow‐up. The was initially discovered by echocardiography, and confirmed further investigations using cardiac magnetic resonance CMR imaging 320‐row detector computed tomography (320R‐ CT ).

Abstract Aims Recurrent heart failure hospitalization (HFH) is an important feature of the progression (HF). In Treatment Preserved Cardiac Function Heart Failure with Aldosterone Antagonist (TOPCAT) trial, we analysed risk factors for recurrent HFH events in HF patients preserved ejection fraction (HFpEF) and developed a prediction model HFH. Methods results This analysis focused on subset TOPCAT participants enrolled Americas ( n = 1767). was defined as two or more hospitalizations during...

Cardiac resynchronization therapy (CRT) improves heart function and prognosis in third-degree atrioventricular block (AVB) patients with failure (HF). However, it is still unclear how to screen for appropriate before implantation. This study aimed evaluate the value of using QRS duration predict CRT efficacy.This enrolled a total 72 AVB HF who received The were divided into Groups A (QRS < 120 ms, 33 cases), B (120 ms ≤ 150 22 C ≥ 17 cases) according their baseline duration. effects...

This study investigated whether tissue Doppler imaging parameters, especially the peak systolic velocity of left ventricular lead-implanted segment (Ss), affect cardiac resynchronization therapy response.In this case-control study, 110 enrolled patients were divided into cases (responder group, n=65) and controls (nonresponder n=45) based on their end-systolic volume was reduced by ≥15% at 6 months after surgery. Preoperative clinical echocardiographic data collected. Multivariate logistic...

Objective: To investigate the safety and efficacy of percutaneous left atrial appendage closure (LAAC) in nonvalvular fibrillation patients (NVAF) with spontaneous echocardiographic contrast (LA SEC). Methods: A total 95 NVAF treated Department Cardiology Ningbo First Hospital from July 2018 to June 2019 were enrolled this study. The study population was divided into two group according presence or absence LA SEC detected by transesophageal echocardiography (TEE). TEE scheduled 45 days...

The influence of different right ventricular lead locations on arrhythmias (VTA) in patients with a cardiac resynchronization therapy (CRT) is not clear. This study aimed to evaluate the VTA CRT when was positioned at middle septum (RVMS) and apical (RVA).A total 352 implanted CRT-defibrillator (CRT-D) between May 2012 July 2016 Department Cardiology Anhui Provincial Hospital were included. Two-year clinical pacemaker follow-up data collected location VTA. Patients divided into RVMS group (n...

Objective To evaluate the role of real-time three-dimensional transesophageal echocardiography(RT-3D TEE) in left atrial appendage (LAA) occlusion. Methods Consecutive 10 fibrillation (AF) patients (CHADS2≥2) with high risk bleeding underwent LAA occlusion under guidance TEE. The orifice shape and characteristics lobes were assessed, size RT-3D TEE wee measured before closer implanation, position device evaluated by TEE.The correlational analysis between diameter occluder was...

Objective To evaluate the efficacy of a quadripolar left ventricular(LV) lead in improving response to cardiac resynchronization therapy(CRT).
