4D‐Flow MRI intracardiac flow analysis considering different subtypes of pulmonary hypertension

open access: yesPulmonary Circulation, 2023
Intracardiac flow hemodynamic patterns have been considered to be an early sign of diastolic dysfunction. In this study we investigated right ventricular (RV) diastolic dysfunction between patients with pulmonary arterial hypertension (PAH) and pulmonary

Endovascular Stenting for Pulmonary Vein Stenosis Following Atrial Fibrillation Ablation: From Diagnosis to Intervention

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Pulmonary vein stenosis (PVS) is an uncommon but serious complication of atrial fibrillation (AF) ablation, often misinterpreted as primary pulmonary disease. Timely identification is essential to prevent irreversible injury and to guide appropriate referral for interventional management. Case Presentations Through the discussion of

In Vivo Dynamic Coronary Arteries Blood Flow Imaging Based on Multi‐Cycle Phase Clustering Ultrafast Ultrasound

open access: yesAdvanced Science
Echocardiography is the most primary clinical modality for dynamic cardiac imaging. However, the vigorous motion of myocardial tissue inherently causes inevitable signal aliasing between blood flow and myocardial tissue in traditional Doppler ultrasound ...

Metabolic changes during cardiac regeneration in the axolotl

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The axolotl is a prominent model organism of heart regeneration due to its ability to anatomically and functionally repair the heart after an injury that mimics human myocardial infarction. In humans, such an injury leads to permanent scarring. Cardiac regeneration has been linked to metabolism and the oxygenation state, but so far,

Progression and prognostic significance of electrocardiographic findings in patients with cardiac amyloidosis

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 809-818, April 2025.
Abstract Aims This study aimed to evaluate the change of the main electrocardiographic (ECG) characteristics and their prognostic role across the main subtypes of cardiac amyloidosis [light‐chain amyloidosis (AL) and hereditary (ATTRv) and wild‐type transthyretin amyloidosis (ATTRwt)].

Right Heart Remodeling in Patients with End-Stage Alcoholic Liver Cirrhosis: Speckle Tracking Point of View [PDF]

open access: yes, 2019
BACKGROUND: Data regarding cardiac remodeling in patients with alcoholic liver cirrhosis are scarce. We sought to investigate right atrial (RA) and right ventricular (RV) structure, function, and mechanics in patients with alcoholic liver cirrhosis.

Application of Echocardiography on Transgenic Mice with Cardiomyopathies

open access: yesBiochemistry Research International, 2012
Cardiomyopathies are common cardiac disorders that primarily affect cardiac muscle resulting in cardiac dysfunction and heart failure. Transgenic mouse disease models have been developed to investigate the cellular mechanisms underlying heart failure and
