Background: Adults with congenital heart disease (ACHD) and atrial arrhythmias (AA) face an increased risk of thromboembolic events. Limited data exist on the use of non-vitamin K oral anticoagulants for thromboprophylaxis in ACHD. We aimed to assess the effectiveness and safety of apixaban in ACHD patients with AA.

The purpose of this study was to define whether there is any clinical impact on the occurrence of ischemic and hemorrhagic events in patients with AHREs and initiation of oral anticoagulation (OAC). Methodology Patients with AHREs who had received cardiac implantable electronic devices (CIEDs, i.

- Patients with diabetes mellitus (DM), particularly type II DM (T2DM), are at a higher risk for developing heart failure (HF), yet there is limited data on how prevalent different stages of HF are among this group in Greece.
- This study aims to investigate the occurrence and progression of HF stages in T2DM patients diagnosed in the last decade (with no prior HF history) and to identify factors that may lead to symptomatic HF in these patients.
- Using a multi-center, prospective cohort design involving 300 patients across 11 specialized cardiology centers, the study will track various health data over 24 months to determine the rates of symptomatic HF and other HF stages in this population.
This research aims to develop a consistent computational model of a normal mitral valve (MV) and describe mitral regurgitation (MR) geometry based on Carpentier's classification. MV geometry was assessed by 2D transthoracic echocardiogram in 100 individuals. A 3D parametric geometric model of the MV was developed.

Article Synopsis
- Heart failure (HF) is a major reason for unplanned hospital admissions globally, often complicated by other health issues, leading to many patients being treated in Internal Medicine Departments (IMD) rather than Cardiology Departments (CD).
- A study involving 302 patients with acutely decompensated HF examined the differences in demographics, treatment, and short-term outcomes between those admitted to IMD and CD, revealing that IMD patients were older and had less severe symptoms upon admission.
- Results showed higher in-hospital mortality (21% in IMD vs. 6% in CD) and increased rates of rehospitalization for HF within 30 days and 6 months for patients admitted to IMD, indicating poorer short-term
