Epicardial adipose tissue (EAT) can play an important role in the occurrence and development of atrial fibrillation and stroke. In this study, we explored the relationship between left atrial epicardial adipose tissue (LA-EAT) and left atrial appendage flow velocity (LAA-FV) in patients with nonvalvular atrial fibrillation (NV-AF). A total of 145 patients with NV-AF who underwent their first radiofrequency ablation were enrolled. They underwent left aortopulmonary vein computed tomography angiography (CTA) and transesophageal echocardiography (TEE) before AF ablation. Left atrial (LA) electroanatomical mapping was performed intraoperatively to assess left atrial voltage. Univariate regression analysis showed that LAA-FV was lower in patients with a low voltage zone (LAA-FV; 35.02 ± 10.78 cm/s vs. 50.60 ± 12.17 cm/s, P < 0.001). A multiple linear regression model showed that the left atrial low voltage zone (β = - 0.311 P < 0.001), LA-EAT volume (β = - 0.256 P < 0.001), left atrial appendage shape (β = - 0.216 P = 0.041), LAVI (β = - 0.153 P = 0.041), and type of atrial fibrillation (paroxysmal vs. persistence) (β = - 0.146 P < 0.048) were independent predictors of LAA-FV. In NV-AF patients, the increase in LA-EAT volume is related to the decrease in LAA-FV.

Usefulness of Artificial Pneumothorax during Totally Endoscopic Off-Pump Left Atrial Appendage Closure and Surgical Ablation.
Ann Thorac Cardiovasc Surg

Purpose: In totally endoscopic off-pump left atrial appendage (LAA) closure and surgical ablation, securing the operative field is sometimes difficult in some patients because of a narrow working space caused by an elevated diaphragm or ventricles. In this study, we aimed to investigate the effectiveness of a method that facilitates securing the operative field using an artificial pneumothorax.
Methods: We analyzed 71 consecutive patients who underwent totally endoscopic off-pump LAA closure and bilateral pulmonary vein isolation.

Background: The net benefit of oral anticoagulation in patients with end-stage renal disease on hemodialysis (HD) is uncertain. In recent years, left atrial appendage closure (LAAC) has emerged as an alternative to oral anticoagulation; however, there is scant evidence of LAAC in patients on HD.
Objectives: This study aimed to assess the feasibility and safety of LAAC in patients on HD.

Background: In patients with structurally normal hearts, algorithms using surface electrocardiographic P-wave morphology are helpful to predict focal atrial tachycardia (FAT) location. However, these algorithms have not been formally assessed in patients with adult congenital heart disease (ACHD).
Objectives: This study sought to assess the efficacy of FAT-location prediction algorithms in an adult population of patients with ACHD.

Our patient presented to the emergency room following a motor vehicle accident. The traumatic tricuspid valve rupture was diagnosed by transthoracic echocardiogram, and his respiratory status declined rapidly. He was placed on veno-venous extracorporeal membrane oxygenation (VV ECMO) to bridge him to surgical repair.

Introduction: Heart failure with preserved ejection fraction (HFpEF) is characterised by severe exercise intolerance, particularly in those living with obesity. Low-energy meal-replacement plans (MRPs) have shown significant weight loss and potential cardiac remodelling benefits. This pragmatic randomised trial aims to evaluate the efficacy of MRP-directed weight loss on exercise intolerance, symptoms, quality of life and cardiovascular remodelling in a multiethnic cohort with obesity and HFpEF.
