Congenitally Corrected Transposition of the Great Arteries (CCTGA) is a rare form of congenital heart disease (CHD) that presents with both atrioventricular (AV) and ventriculoarterial (VA) discordance. This condition accounts for a small proportion of CHD, and its presentation in later life can be challenging due to its gradual nature. We present the case of a 74-year-old male misdiagnosed with ischemic cardiomyopathy of left ventricle, who presented with symptoms of congestive heart failure (CHF) after decades of being asymptomatic. Diagnostic work-up revealed features of CCTGA, including severe left AV valve regurgitation and evidence of left sided right ventricular dysfunction. This case highlights the importance of considering CHD in older adults, particularly those presenting with signs of heart failure, and underscores the need for early diagnosis and intervention.
