Severe pulmonary hypertension as a diagnostic challenge: a case of congenitally corrected transposition of the great arteries with dextrocardia in an elderly patient

Congenitally corrected transposition of the great arteries is a rare congenital heart defect that may remain undiagnosed well into adulthood. We present the case of a 71-year-old male with dextrocardia and exertional dyspnoea, initially diagnosed with severe pulmonary hypertension. Further evaluation revealed an underlying congenitally corrected transposition of the great arteries. This case highlights the importance of considering CHD in older adults with unusual cardiac findings.
