The use and diagnostic significance of thallium-201 SPECT imaging in a case of anomalous left coronary artery.
A 6-year-old female with an anomalous left coronary artery (ALCA) originating from the main pulmonary artery underwent a resting Tl-201 SPECT examination before and after surgical reimplantation. Preoperative Tl-201 SPECT images demonstrated decreased perfusion to the anterior wall and a dilated left ventricle. Post operative Tl-201 SPECT images showed marked improvement of perfusion to the anterior wall as well as a decreased left ventricular size. This is one of the few documented demonstrations of a perfusion defect due to an ALCA in a young child using Tl-201 SPECT imaging methods in conjunction with other tests.
