Do You Have to Refrigerate Peanut Butter? Q: My family kept peanut butter in the fridge, but in college all my roommates kept peanut butter at room temperature and I loved how easy it was to spread! Now I keep my peanut butter at room temp too but I recently read you need to keep it in the fridge.
Mitral valve prolapse and regurgitation. When your heart is working properly, the mitral valve closes completely during contraction of the left ventricle and prevents blood from flowing back into your heart's upper left chamber (left atrium).he bulging may keep the valve from closing tightly. When blood leaks backward through the valve, it's called mitral valve regurgitation. This may not cause problems if only a small amount of blood leaks back into the atrium.
Treatment of mitral valve regurgitation depends on how severe your condition is, whether it's getting worse and whether you have symptoms. For mild leakage, treatment may not be necessary. You may need heart surgery to repair or replace the valve for severe leakage or regurgitation.Left untreated, severe mitral valve regurgitation can cause heart failure or heart rhythm problems (arrhythmias).or mild leakage, treatment may not be necessary. You may need heart surgery to repair or replace the valve for severe leakage or regurgitation.
