I have mitral valve prolapse and am severely depressed.i don't have health insurance, but i have been feeling so depressed.is it due to mvp?

Doubt it: Mitral valve prolapse is a disorder of the mitral valve where the leaflets close abnormally. The majority of prolapse patients have no issues with their prolapse. It does increase the risk of developing mitral regurge in the future. It affects nearly 10% of people. Depression is also common at 3-5% of people. There are many more likely stressors leading to depression. There is no proven connection.
