Congenitally corrected transposition of the great arteries and coronary artery disease: a case report in an 83-year-old male

In patients with CCTGA, major factors contributing to morbidity and mortality include progressive decline in systemic RV function and systemic tricuspid valve regurgitation. A retrospective study showed that 25% of uncomplicated CCTGA patients develop heart failure by age 45, while approximately two-thirds of complicated cases do. Survival beyond age 70 is rare. Prompt management of CAD through angioplasty is critical to prevent further deterioration of RV function and worsening tricuspid regurgitation. However, the atypical positioning of the aorta and coronary arteries complicates selective coronary angiography, making a challenging diagnosis and treatment.
