Anesthetic Management of a Patient with Unruptured Sinus of Valsalva Aneurysm with Right Ventricular Outflow Tract Obstruction

抄録

Sinus of Valsalva aneurysm (SVA) is a rare cardiac defect that can be congenital or acquired through infection, trauma, or degenerative diseases. A 79-year-old man was diagnosed with upper jaw cancer and in preoperative transthoracic echocardiography and computed tomography was found to have an unruptured right SVA causing right ventricular outflow obstruction. Under general anesthesia, surgical repair was performed after instituting cardiopulmonary bypass. We successfully performed the anesthetic management of the SVA surgical repair using transesophageal echocardiography.
