Dexmedetomidine sedation for transesophageal echocardiography during percutaneous atrial septal defect closure in adult

Atrial septal defect [ASD] is second common congenital heart disease that often leads to adult period. Intracardiac or transesophageal echocardiography [TEE] is essential for percutaneous closure of ASD using Amplatzer septal occluder. Dexmedetomidine [DEX], which is a highly selective a-agonist, has sedative and analgesic properties without respiratory depression in the clinical dose range. We report percutaneous closure of ASD with TEE under DEX sedation
