Management of general anesthesia for tricuspid valve replacement in an adult patient with a corrected transposition of the great arteries with no associated cardiac anomalies: A case report

Abstract

　Corrected transposition of the great arteries (cTGA) is a very rare congenital heart defect that accounts for <1% of all congenital heart disorders; only a few case reports describe general anesthesia in patients with this condition. We report a case of general anesthesia in an adult patient with cTGA who underwent successful tricuspid valve replacement due to severe tricuspid regurgitation. Since the right ventricle supports systemic circulation in cTGA, such patients have a low tolerance for increasing preload and afterload. In the anesthetic care of these patients, personalized hemodynamic management is required, which is based on comprehensive evaluation of the right ventricle with transesophageal echocardiography, pulmonary artery catheterization, and intraoperative findings.
