Summary
A rare case of a divided right atrium and abnormal coronary veins in a young woman highlights potential embryological links. This condition, potentially caused by venous valve regression failure, led to exertional dyspnea post-surgery.
Area of Science:
- Cardiovascular Medicine
- Embryology
- Congenital Heart Disease
Background:
- A patient with a history of surgical repair for a divided right atrium and atrial septal defect presented with exertional dyspnea.
- The patient developed symptoms 8 years after initial surgical intervention.
Observation:
- Selective coronary angiography revealed significant coronary artery and vein abnormalities.
- Findings included a dilated right coronary artery with a fistulous connection to the right atrium.
- Tortuous coronary veins were observed draining directly into cardiac chambers, with absence of the coronary sinus.
Findings:
- The study identified a complex congenital heart anomaly involving both atrial septation and anomalous venous drainage.
- Coronary angiography demonstrated a rare combination of coronary artery fistula and generalized coronary vein ectasia.
Implications:
- The findings suggest a potential embryological basis, possibly due to the regression failure of the right venous valve.
- This case underscores the importance of comprehensive cardiovascular assessment in patients with complex congenital heart defects.
- Understanding these embryological links may inform future diagnostic and therapeutic strategies for similar rare conditions.
