title: Anesthetic management of a patient with obstructive prosthetic aortic valve dysfunction: a case report.
abstract: We present a 55-year-old female patient who underwent burr-hole drainage due to chronic subdural hematoma, with obstructive prosthetic aortic valve dysfunction. Anesthetic management of a patient with severe obstructive prosthetic aortic valve dysfunction can be challenging. Similar considerations should be given to patients with aortic stenosis with an additional emphasis on thrombotic complication due to discontinuation of anticoagulation, which may further jeopardize the valve dysfunction. This case emphasizes the importance of a comprehensive understanding of the etiology and hemodynamic consequences of obstructive prosthetic valve dysfunction and the adequacy of anticoagulation for patients undergoing noncardiac surgery even after a successful valve replacement.
