Wheezing as the sole clinical manifestation of cor triatriatum

Cardiac malformations involving low‐pressure chambers (i.e., either of the atria) are more often diagnosed later in life than lesions that involve high‐pressure systems such as ventricular septal defects or persistent ducti arteriosi. Patients with congenital heart disease involving the atria may present only symptoms suggesting lung disease. We report on a child with recurrent episodes of wheezing, which did not respond to albuterol nebulizations and intravenous corticosteroids; he was subsequently found to have cor triatriatum. When a patient suffers from recurrent episodes of lower pulmonary infection and wheezing, despite appropriate management for asthma, less common (including cardiac) causes should be considered.
