Usually heart failur: The most common (but not sole) cause of pulmonary edema is heart failure. When the pumping function of the left side of the heart fails, fluid backs up into the lungs. That is pulmonary edema. It causes shortness of breath associated with low amount of oxygen in blood. If the bypass failed to improve dad's heart function that could have been a cause. MANY other causes are possible.
