Myxoma is the most common type of cardiac tumour in all age groups. It may simulate infective endocarditis but is rarely infected. We describe one case of infected left atrial myxoma caused by Enterococcus faecalis. Combined therapy, consisting of surgical management and antimicrobial therapy, was used. Histological examination of the excised tumour revealed a typical myxoma with infiltrates of neutrophils. Few cases of infected atrial myxomas have been reported in the literature.

Cardiac implantable electronic devices (CIEDs), including pacemakers, implantable cardiac defibrillators (ICD), and cardiac resynchronization therapy (CRT) devices, regulate heart rate and rhythm in patients with cardiac conditions. With an aging population, CIED-related complications, especially pacemaker pocket infections, are rising. Risk factors include frailty, older age, and superficial device fixation, while risk mitigation involves larger pocket sizes, submuscular fixation, and absorbable antibacterial envelopes.

Background: This case report highlights the conduction disorder anomalies associated with dengue infection, particularly bradyarrhythmias due to dysfunction of the sinus node and atrioventricular node, which may require cardiac stimulation such as pacemaker implantation. This case emphasizes the importance of continuous monitoring and the use of additional diagnostic techniques to detect complications in a timely manner.
Case Summary: A 31-year-old male patient was admitted to our institution with symptoms of dyspnoea, orthopnoea, and severe bradycardia.

People living with HIV are at higher risk of heart failure and associated left atrial remodeling compared to people without HIV. Mechanisms are unclear but have been linked to inflammation and premature aging. Here we obtain plasma proteomics concurrently with cardiac magnetic resonance imaging in two independent study populations to identify parallels between HIV-related and aging-related immune dysfunction that could contribute to atrial remodeling and clinical heart failure.

Background: The risk of thrombosis increases after SARS-CoV-2 infection. This study aimed to assess associations between pre-infection anticoagulant exposure and SARS-CoV-2 infection-related outcomes in a population-based cohort.
Methods: Members of the "Meuhedet" health maintenance organization aged >45 years who tested positive for SARS-CoV-2 infection (03/2020-04/2022) were followed.

Rationale: Patients with atrial fibrillation and a large goiter have high perioperative risks and often cannot tolerate general anesthesia, making it necessary for us to explore new safe and effective anesthesia methods.
Patient Concerns: The patient presented with atrial fibrillation accompanied by rapid ventricular rate, a thrombus attached to the left atrial appendage, and a massive thyroid goiter compressing the airway.
Diagnosis: After the left humerus fracture surgery, the patient's internal fixation loosened and fractured, accompanied by infection, formation of sinus tracts, and suppuration.
