Anesthetic challenges of decompressive craniotomy for the right frontal lobe abscess in a patient with Ebstein's anomaly: A rare case report.

Ebstein's anomaly is a rare congenital heart disease characterized by downward displacement of the tricuspid valve, atrialization of right ventricle, enlarged right atrium with tricuspid regurgitation, or stenosis. It is often associated with atrial septal defect (ASD) or patent foramen ovale with right to left shunt. It has a varied clinical presentation and can manifest as cyanosis, ventricular, or supraventricular arrhythmias and recurrent episodes of congestive heart failure. We describe the anesthetic management of a female patient with Ebstein's anomaly who had right frontal lobe abscess due to paradoxical embolism for decompressive craniotomy.
