Mid-aortic syndrome (MAS) is a rare clinical entity that is characterized by coarctation involving the distal thoracic and/or abdominal aorta and its major branches accounting for 0.5–2% of all cases of coarctation of the aorta (1). Renovascular hypertension can be a significant sequelae - it is the main symptomatic presentation of this disease among children and adolescents. We describe a 9-year-old girl who presents with recurrent abdominal pain and symptomatic hypertension. Due to significant left ventricular systolic dysfunction and uncontrolled hypertension, percutaneous balloon angioplasty was performed to treat the coarctation. To our knowledge, this is the first reported case of MAS in Malaysia. This case report highlights the clinical presentation, the role of computed tomography angiogram (CTA) in the diagnosis and current options in the management of MAS.

The use of pediatric cardiothoracic CT for congenital heart disease (CHD) was traditionally limited to the morphologic evaluation of the extracardiac thoracic vessels, lungs, and airways. Currently, the applications of CT have increased, owing to technological advancements in hardware and software as well as several dose-reduction measures. In the previously published part 1 of the guideline by the Asian Society of Cardiovascular Imaging Congenital Heart Disease Study Group, we reviewed the prerequisite technical knowledge for clinical applications in a user-friendly and vendor-specific manner. Herein, we present the second part of our guideline on contemporary clinical applications of pediatric cardiothoracic CT for CHD based on the consensus of experts from the Asian Society of Cardiovascular Imaging CHD Study Group. This guideline describes up-to-date clinical applications effectively in a systematic fashion.
