As mitral stenosis progresses, increased left atrial pressure is required to maintain stroke volume. This pressure increase is generated primarily by the right heart and results in increased ...

"If the heart isn't relaxing, the filling pressure increases, which means the atrial pressure increases, and that can lead to hypertrophy and fibrosis of the atrium, both of which increase the ...
