Abstract
Pericardial cyst is a rare disorder with incidence of 1:100000 and is usually asymptomatic. Atrial septal defect on the other hand has incidence of 1.6:1000 live births with 97% chance of survival till adulthood and rarely causes Eisenmenger syndrome in early adulthood. We present a case where there was dramatic occurrence of sudden hypoxia and features of right heart failure in otherwise healthy adult because of the combination of these two entities.
Highlights
Most pericardial cysts are asymptomatic and detected during other investigations of the chest
We present a case where there was dramatic occurrence of sudden hypoxia and features of right heart failure in otherwise healthy adult because of the combination of these two entities
Sometimes hypoxia and right to left shunt in Atrial septal defect (ASD) in absence of pulmonary artery hypertension has been reported in patients due to well developed eustachian valve directing the venous blood to left atrium[8]
Summary
Most pericardial cysts are asymptomatic and detected during other investigations of the chest. We present a case where there was dramatic occurrence of sudden hypoxia and features of right heart failure in otherwise healthy adult because of the combination of these two entities. Hemorrhage into a pericardial cyst following blunt trauma to the chest results in tamponade. Compression and right ventricular failure has been reported[2].
