An atrial septal defect (ASD) is a common congenital heart anomaly that results in irregular blood flow between the systemic and pulmonary circulations due to an opening in the atrial septum. Ostium secondum ASD accounts for a large proportion of these defects and often goes unnoticed during childhood and adolescence. Pulmonary hypertension (PH), affecting a significant number of patients with ostium secondum ASD, is associated with functional limitations, heart failure, and tachyarrhythmias.

Aims: Outcome in pulmonary arterial hypertension (PAH) is determined by right ventricular (RV) function adaptation to increased afterload. Echocardiography is easily available to assist bedside evaluation of the RV. However, no agreement exists about the feasibility and most relevant measurements.

Pulmonary arterial hypertension (PAH) is a rare and potentially fatal condition characterized by progressive increases in blood pressure in the arteries of the lungs. Oral selexipag, approved by the Food and Drug Administration (FDA) in 2015 for the treatment of PAH, targets prostacyclin receptors on pulmonary arterial vascular smooth muscle and endothelial cells to improve blood flow through the lungs and reduce pulmonary vascular resistance. Oral selexipag is effective, but may be discontinued due to factors like side effects, emergency conditions, or inability to take oral medication, potentially leading to severe adverse events, such as rebound pulmonary hypertension and right heart failure.

The relationship between cancer and thrombosis was initially highlighted in the 19th century. Vascular complications in oncology can be arterial or venous thrombosis, and incidental pulmonary embolism is a growing challenge. We aimed to describe the frequency and clinical characteristics of cancer patients with incidental venous thromboembolism (iVTE).

The waning immunity following the COVID-19 vaccination become a significant concern and the immunological dynamics of vaccine-induced antibodies after vaccination need to be explored. The aim of this study was to compare anti-SARS-CoV-2 receptor-binding domain (RBD) antibody levels before and after a booster dose with heterologous COVID-19 vaccine and to identify factors influencing the levels after receiving the booster dose. A cross-sectional study was conducted in which individuals who received primary doses of CoronaVac and a booster dose with an mRNA-based vaccine were recruited using a purposive sampling technique.
