Insights
Congenitally corrected transposition of the great arteries (ccTGA) is a rare heart defect. This case highlights ccTGA diagnosis in an active duty service member, emphasizing its impact on quality of life.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Medical Imaging
Background:
- Congenitally corrected transposition of the great arteries (ccTGA) is a rare congenital heart disease, affecting less than 1% of cases.
- ccTGA involves complex atrioventricular and ventriculoarterial discordance.
- Often associated with ventricular septal defects, right ventricular outflow tract obstruction, and tricuspid valve abnormalities.
Purpose of the Study:
- To present a case of congenitally corrected transposition of the great arteries.
- To illustrate the diagnostic process using cardiac gated computed tomography.
- To underscore the clinical implications of ccTGA on patient health and quality of life.
Main Methods:
- Case report presentation.
- Diagnostic evaluation utilizing cardiac gated computed tomography.
- Clinical referral for valvular heart disease assessment.
Main Results:
- Diagnosis of congenitally corrected transposition of the great arteries in a 33-year-old active duty Air Force lieutenant.
- Identification of ccTGA during evaluation for valvular heart disease.
- The case highlights the importance of advanced imaging in diagnosing rare cardiac conditions.
Conclusions:
- Congenitally corrected transposition of the great arteries can impact exercise tolerance and quality of life.
- Cardiac gated computed tomography is effective in diagnosing ccTGA.
- Early diagnosis and management are crucial for patients with ccTGA.
Abstract:
Congenitally corrected transposition of the great arteries is a rare condition accounting for less than 1% of all congenital cardiac diseases. The fundamental nature of this condition involves a blend of atrioventricular as well as ventriculoarterial discordance. Congenitally corrected transposition of the great arteries is classically associated with three additional abnormalities, including ventricular septal defect, right ventricular outflow tract obstruction, and tricuspid valve abnormalities. Patients with this anomaly have been shown to exhibit reduced exercise tolerance as well as reduced health-related quality of life when compared to patients with normal cardiovascular anatomy. We present the case of a 33-year-old active duty lieutenant in the United States Air Force referred to the cardiology clinic for evaluation of valvular heart disease with subsequent discovery of congenitally corrected transposition of the great arteries on cardiac gated computed tomography.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
