A 3-year-old boy underwent right ventricular outflow tract reconstruction and arterial duct closure due to pulmonary artery atresia (PA) 3 years ago. Postoperative cardiac CT showed the main pulmonary artery stenosis. He was scheduled to undergo cardiac magnetic resonance imaging (MRI) to clarify the diagnosis. Due to the long duration and loud noise during the MRI examination, oral chloral hydrate and intranasal dexmedetomidine were given to facilitate procedural sedation for the MRI examination.

摘要

A 3-year-old boy underwent right ventricular outflow tract reconstruction and arterial duct closure due to pulmonary artery atresia (PA) 3 years ago. Postoperative cardiac CT showed the main pulmonary artery stenosis. He was scheduled to undergo cardiac magnetic resonance imaging (MRI) to clarify the diagnosis. Due to the long duration and loud noise during the MRI examination, oral chloral hydrate and intranasal dexmedetomidine were given to facilitate procedural sedation for the MRI examination.
