- Abstract
- This case illustrates the reopening of foramen ovale in a young patient with chronic pulmonary hypertension caused by bronchiectasis and chronic pulmonary fibrosis, which resulted in a prominent right-to-left shunt and severe hypoxia. Her clinically unsuspected right-to-left shunt was discovered during ventilation-perfusion scan, which was performed for the evaluation of pulmonary embolism. She had common variable immune deficiency, a primary immunodeficiency disease in which B-lymphocytes produce few or no antibodies. Most patients with this syndrome have an intrinsic defect in their B-lymphocytes that results in reduced immunoglobulin production. In these patients, recurrent respiratory tract infections are common and may result in chronic lung disease, fibrosis, particularly bronchiectasis (20-30%) and even cor pulmonale as happened in our patient [J. Clin. Immunol. 9 (1989) 22-33.].
