Allele-specific expression (ASE) is differential expression of each of the two chromosomal alleles of an autosomal gene. We assessed ASE patterns in the human left atrium (LA, n = 62) and paired samples from the left ventricle (LV, n = 76) before and after ischemia, and tested the utility of differential ASE to identify genes associated with postoperative atrial fibrillation (poAF) and myocardial ischemia.

To describe the morphological characteristics of left atrial appendage (LAA) on multislice computed tomography in patients with atrial fibrillation. Materials and methods: A prospective descriptive study on 44 patients diagnosed with atrial fibrillation (AF) and underwent multislice computed tomography at Bach Mai Hospital from August 2022 to July 2023.

While it is the most common thoracic venous anomaly, a persistent left vena cava superior may present in atypical variations, which are important to consider during clinical management. To the best of our knowledge, this is the first report of a persistent left vena cava superior draining into the left atrial appendage.

Acute cardiac tamponade is a rare event during any type of interventional or surgical procedure. It can occur during electrophysiology procedures due to radiofrequency ablation, lead or catheter manipulation, transseptal puncture, laser lead extractions, or left atrial appendage occlusion device positioning.

For patients with heart failure combined with complete left bundle branch block, cardiac resynchro‑ nization therapy is an important therapeutic method. If these patients also have atrial tachycardia, how to choose a treatment strategy deserves discussion.

Insulin resistance is an overlapping risk factor for both heart and breast cancer, while its interaction with cardiotoxicity in breast cancer (BC) patients is not clear. This study investigated the impact of insulin resistance on cardiac remodeling in patients with human epidermal growth factor receptor 2 (HER2)-positive BC during and after trastuzumab therapy in real-world clinical practice.

Novel oral anticoagulants (NOACs) have made the use of anticoagulation in patients with atrial fibrillation (AFib) much more convenient and predictable. It is a very common practice to hold anticoagulation either in anticipation of surgical procedures (to prevent excessive bleeding) or in case of acute bleeding episodes.

Cardiac lymphoma is a rare neoplasm involving heart, pericardium or both, usually seen in immunocompromised patients. We report a 61-year-old male presenting with worsening shortness of breath and 20-pound weight loss. Investigations showed right-sided tumor with interatrial septal wall perforation and left atrial expansion.

Primary cardiac tumors are an incredibly rare finding. Cardiac myxomas are the most primary cardiac tumors that often occur within the left atrium. When left untreated, they pose a high risk of causing hemodynamic collapse by obstruction or can embolize and result in thromboembolic stroke. The presentation of cardiac myxoma varies greatly and can be associated with significant morbidity and mortality when undiagnosed.

To compare the efficiency of atrial fibrillation (AF) ablation combined with mitral valve (MV) surgery through port-access with through traditional approach. From July 2019 to October 2021, 81 patients with long-standing persistent rheumatic AF underwent biatrial ablation using monopolar radiofrequency devices combined with MV surgery.

Intra-atrial right coronary artery and anomalous origin of left circumflex artery found concurrently
Coronary artery anomalies (CAAs) are known to be anatomical aberrations in the origin and structure. Due to the diverse anatomical variants, surgeons and angiographers have struggled when faced with patients who have CAA.

Radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) in patients with prosthetic valve is still a challenge because of the higher recurrence rate and difficult manipulation of catheters in the left atrium which may lead to higher risk of complications. We presented the first AF ablation in Vietnam of a patient who had mitral and aortic mechanical valves.

Restrictive cardiomyopathy (RCM) is a common myocardial disease in cats, characterized by diastolic dysfunction and atrial enlargement without myocardial hypertrophy. Especially, endomyocardial form of RCM, one of the subtypes in RCM, is characterized by endocardial fibrosis, endocardial scar bridging the interventricular septum and left ventricular (LV) free wall, and deformation and distortion of the LV.

Left atrial (LA) function plays an important role in diastolic dysfunction in cats with hypertrophic cardiomyopathy (HCM). Two-dimensional speckle tracking echocardiography (2D-STE) is a technique for assessing LA function. This study aimed to evaluate the LA function in HCM cats compared to normal cats, using 2D-STE.

Prior studies have suggested that pimobendan is associated with several positive effects in cats, including improved survival in cats with congestive heart failure and improved left atrial function in research colony cats with hypertrophic cardiomyopathy (HCM) and normal cats. However, there is still a paucity of pharmacodynamic data refuting or supporting the use of pimobendan in a clinical cat population.

The left atrium (LA) is an important prognostic parameter in cardiac pathologies of cats. Its size is currently measured in one-dimensional methods, while human medicine considers two- and three-dimensional echocardiography as standard.

Myxomas are rare tumours but are the most common benign tumours of the heart. They can arise from any heart chamber. However, they arise more frequently from the inter-atrial septum of the left atrium. When diagnosed, these need to be surgically excised as early as possible as these are known to cause dangerous complications, e.g. intracardiac obstruction and embolism.

Anemia and echocardiographic systolic and diastolic parameters are useful predictors of cardiovascular outcomes in patients with atrial fibrillation (AF). However, no studies have evaluated the use of anemia for predicting cardiovascular outcome in AF patients when the important echocardiographic parameters are known.
