AI Article Synopsis
- A 33-year-old woman underwent myocardial perfusion scintigraphy (MPS) to check for coronary artery disease, revealing an unexpected heart orientation known as dextrocardia.
- The electrocardiogram (ECG) indicated a right axis deviation, suggesting abnormalities in heart function.
- Upon reviewing her medical history, it was found that she had undergone surgery for transposition of the great arteries, causing the right ventricle to function as the systemic ventricle, which explained the MPS findings.
Article Abstract
We report a case of a 33-year-old woman who underwent stress and rest myocardial perfusion scintigraphy (MPS) to exclude coronary artery disease. MPS images showed an apparent dextrocardia with a right-sided septal wall uptake. The electrocardiograph showed a right axis deviation with dominant R waves at leads aVR and V1. Upon retrieval of the patient's medical records, she had an underlying transposition of great arteries and underwent a Senning atrial switch surgery. Hence, the MPS images demonstrated a prominent right ventricular wall due to its function as the "systemic" ventricle with minimal uptake in the "pulmonary" left ventricle.
