Mystery still unresolved: Untouched "Blue heart" presenting at 40yrs of age

Area of Science:

• Cardiology
• Congenital Heart Disease
• Adult Congenital Heart Disease

Background:

• Dextro-transposition of the great arteries (d-TGA) is a severe cyanotic congenital heart disease.
• Surgical correction is typically required in infancy for survival.
• Survival into adulthood with unrepaired d-TGA is exceptionally rare.

Observation:

• This case presents a 40-year-old individual with unrepaired d-TGA.
• The patient exhibited moderately elevated pulmonary artery pressures.
• Symptoms were relatively stable despite the condition's severity.

Findings:

• The case challenges the typical lethal prognosis of unrepaired d-TGA.
• The presence of intracardiac shunts did not prevent late adult presentation.
• This highlights potential, yet unexplained, compensatory mechanisms in some d-TGA patients.

Implications:

• This case underscores the need for further research into long-term survival factors in unrepaired congenital heart disease.
• It may inform diagnostic and management strategies for adult congenital heart disease patients.
• Understanding such rare presentations can improve clinical awareness and patient care for complex cardiac conditions.
