Surgical-Relevant Coronary Artery Anomalies Diagnosed by Cardiac Computed Computed Tomographic Angiography in Infants and Children with Right Ventricular Outflow Tract Obstruction

摘要

Approximately 19% of congenital heart defects involve some degree of Right Ventricular Outflow Tract (RVOT) obstruction.1 These obstructions can be at the level of the pulmonary valve, infundibulum, proximal branches, or distal branches of the pulmonary artery.2 The severity of the clinical presentation is usually dependent on the severity of RVOT obstruction and can range from an asymptomatic infant to one that is severely cyanotic.
