Background: Light-chain cardiac amyloidosis (AL-CA) is associated with structural and functional changes in the left atrium and left ventricle. This study aims to assess the value of the left atrioventricular coupling index (LACI) assessed by three-dimensional echocardiography (3DE) for predicting primary outcome in AL-CA.
Methods: Participants with biopsy-confirmed AL-CA from April 2022 to February 2024 were prospectively analysed.

Unlabelled: Introduction Acute heart failure (AHF) is a life-threatening condition that requires swift diagnosis and tailored management to enhance patient outcomes. In the pursuit of more precise prognostic indicators, Tricuspid Annular Plane Systolic Excursion (TAPSE) and Pulmonary Arterial Systolic Pressure (PASP) have emerged as potential significant advancements. The TAPSE/PASP ratio, a novel parameter, has recently gained attention as a promising predictor of outcomes in acute heart failure.

Background: Aortic valve sclerosis (AVS) is a progressive atherosclerotic disease associated with future cardiovascular events (CVE). However, whether its development and prognostic value are independent of arterial atherosclerosis has not been thoroughly investigated. We evaluated the determinants and prognostic value of AVS in conjunction with carotid atherosclerosis.

Background: This study aimed to determine whether artificial intelligence (AI)-based automated assessment of left atrioventricular coupling index (LACI) can provide incremental value above other traditional risk factors for predicting mortality among patients with severe aortic stenosis (AS) undergoing coronary CT angiography (CCTA) before transcatheter aortic valve replacement (TAVR).
Methods: This retrospective study evaluated patients with severe AS who underwent CCTA examination before TAVR between September 2014 and December 2020. An AI-prototype software fully automatically calculated left atrial and left ventricular end-diastolic volumes and LACI was defined by the ratio between them.

Aims: To investigate the distribution of left atrioventricular coupling index (LACI) among patients with heart failure and left ventricular ejection fraction (LVEF)<50% and to explore its association with the combined endpoint of all-cause death or HF hospitalization at long term follow-up.
Methods And Results: Patients with HF and LVEF<50% undergoing cardiac magnetic resonance (CMR) were evaluated. Patients with atrial fibrillation or flutter were excluded.
