Pericardial Effusion. Pericardial effusion is abnormal fluid build up in the membrane surrounding the heart called the pericardial sac. The clinical signs owners report depends on the amount of fluid accumulation as well as the rate of development of the fluid. Slowly accumulating fluid allows time for the pericardial sac to stretch and expand. Since the heart has time to adjust to the new fluid accumulation the intracardiac pressure does not increase to affect the filling ability of the heart until a critical point is reached.
