A 61-year-old man is frustrated because he is no longer able to walk up a flight of stairs without stopping to catch his breath. He has also been plagued by a dry cough for the past six months. He has not visited his primary care physician because he is not a smoker and does not believe that he could have a serious pulmonary condition. He ignores his symptoms for another eight months, during which time they continue to worsen. He finally visits his physician at the urging of his wife. While shaking hands, his physician notices that the patient has clubbing of the fingers. A clinical work-up and medical history fail to find a cause for this restrictive lung disease. What is the definitive therapy for this patient’s most likely condition?
(D) Lung transplantation
