Physiologic Studies in Congenital Absence of the Left Main Pulmonary Artery
Physiologic studies in 2 cases of congenital absence of the left pulmonary artery are presented. The significance of carbon dioxide production and oxygen uptake in the affected lung and their relationship to ventilation and perfusion are discussed. All functional and anatomic evidence points to a highly significant bronchial artery circulation substituting in part for the absent pulmonary artery.
