title: Acute right heart failure due to adenotonsillar hypertrophy.
abstract: A case is presented in which a child with underlying chronic lung disease, developed cor pulmonale and severe pulmonary hypertension as a result of adenotonsillar hypertrophy. His cardiac function acutely decompensated with an upper respiratory infection which exacerbated his obstructive sleep symptoms. Pre and postoperative documentation of cardiopulmonary function was critical in the peri-operative management of this patient. His severe pulmonary hypertension was stabilized using a nasopharyngeal airway and medications pre-operatively, in order to minimize his risk of anesthesia. He continued to require careful monitoring and manipulation of his medications after adenotonsillectomy and bronchoscopy. Serial echocardiograms documented the effects of the various interventions implemented in this patient. Severe acute right heart failure is an unusual complication of obstructive sleep apnea. However, this may become more common as more children survive prematurity and its associated chronic lung disease. These children may have subclinical lung disease and/or chronic pulmonary hypertension even after they no longer require supplemental oxygen and bronchodilators. Because these children are often tenuous, with regard to their cardiopulmonary function, they may be at increased risk to develop significant complications related to obstructive sleep apnea. It is important that a physician familiar with the management of pulmonary hypertension be involved in the care of these patients.
