What is the diagnosis?
Extensive coronary collateralisation with occluded arteries
ARCAPA (Anomalous Right Coronary Artery (RCA) from Pulmonary Artery (PA)
Takayasu’s disease
Correct! The correct answer is "ARCAPA (Anomalous Right Coronary Artery (RCA) from Pulmonary Artery (PA)".
 
ARCAPA is a rare congenital disease with .002 % incidence. The angiogram and the CTCA demonstrate RCA originating from PA. The left system is ectatic and extensive collateralisation is seen between the two, suggesting retrograde filling.
Good try! The correct answer is "ARCAPA (Anomalous Right Coronary Artery (RCA) from Pulmonary Artery (PA)".
