Disclosed herein are devices and methods for addressing elevated left-sided filling pressures to mitigate the effects of diastolic dysfunction. The disclosed technologies decrease the temporal increase in blood flow and pressure into the heart from the venous system (which drains from the body). Under exertion, there is a shift of blood from the 'unstressed' reservoir of vasculature to the 'stressed' reservoir. By inhibiting this acute shift of blood from the unstressed reservoir to the stressed reservoir, an undesirable influx of blood volume to the already overloaded left heart can be avoided. Certain embodiments provide ways to maintain or to increase atrial elasticity, or atrial compliance using devices implanted in the left atrium and / or left atrial appendage. This increase or enhancement of atrial compliance enables the atrium to absorb the energy of short bursts of high left atrial pressure.
