This condition typically occurs alongside chronic bronchitis and leads to breathing difficulties and discomfort affecting both the lungs and the heart. In its advanced stages, it is identifiable by the chest taking on a barrel-like shape and severely limited chest expansion, which may be as little as half an inch. It is also referred to as pneumonectasia or pneumonectasis.
