PAH: Yes it can. In Pulmonary Hypertension, imagine the right side of the heart as a pump and the pulmonary arteries as a dam. When pulmonary artery pressures keep going up, the blood backs up into the pump (heart) and can affect both chambers of the right side of the heart. The Right Atrium can enlarge and the Right Ventricle can enlarge, become thick, or lose ability to pump properly.
