Disorders of the pulmonic valve (PV) receive considerably less attention than other forms of valvular heart disease. Due to the dramatically improved survival of children with congenital heart disease over the last 5 decades, there has been a steady increase in the prevalence of adults with congenital heart disease, which necessitates that clinicians become familiar with the anatomy and the evaluation of right ventricular outflow tract and PV anomalies. A multimodality imaging approach using echocardiography, cardiac computed tomography, and magnetic resonance imaging is essential for a comprehensive evaluation of the anatomy and function of the right ventricular outflow tract, PV, and supravalvular region.

- The study explores how sitting for long periods (sedentary behavior) can increase the risk of heart-related issues like atrial fibrillation and heart failure.
- Researchers analyzed data from over 89,000 participants using accelerometers to measure daily sedentary time and its impact on cardiovascular health.
- Results indicated that those sitting more than 10.6 hours a day faced significantly higher risks for heart failure and cardiovascular death, and moving more (even a little) could help reduce these risks.
Article Synopsis
- Achieving at least 150 minutes of moderate-to-vigorous physical activity weekly lowers the risk of cardiovascular events and is a key public health goal, but the impact of different activity patterns (like "weekend warrior" vs. regular) on disease incidence is unclear.
- A study involving 89,573 UK Biobank participants who wore accelerometers found that both weekend warriors and those who engage in regular physical activity had significantly lower risks of developing various diseases compared to inactive individuals.
- Stronger protective effects were noted for cardiometabolic conditions, with the weekend warrior pattern showing lower risks for hypertension, diabetes, obesity, and sleep apnea, indicating the health benefits of any physical activity, even if concentrated on weekends.
