Purpose
Coronary artery anomalies are categorised uncommon cardiac diseases in general population,
which reported %1-2 prevalance.
Usually diagnosed incidentally,
because of being asymptomatic (1).
Coronary artery anomalies are the underlying cause in 2/3 of suddden deaths caused by cardiac related reasons (2).
Diagnosing the coronary artery diseases,
coronary CT angiography is superior modality.
Recently,
by the use of coronary CT angiography,
the frequency of diagnosing incidental findings accompanying coronary anomalies is increasing.
In our case,
there are atrial septal pouch and left atrial diverticula,
which accompanying...
Methods and Materials
20 years old male patient was admitted our clinic with atypical chest pain.
With 128 slice CT scanner (GE Healthcare Medical Systems,
Revolution),
coronary CT angiography was performed.
Results
RCA and LCX was seen arising with single root from right coronary sinus (Figure 1).
LCX was retroaorticaly located and descending in left atrioventricular groove.
Additionally,
there were left atrial septal pouch and a milimetric diverticula at left atrial superior wall (Figure 2,3).
Conclusion
The prevalance of left circunflex coronary artery origin and course variants was defined as % 0.3-0.8 by various angiographic and cadaver studies.
Variants of the LCX,
arising from left coronary artery,
were defined in three patterns.
RCA and LCX arise from right coronary sinus as different roots (type 1),
RCA and LCX arise from same root (type 2) or LCX arise from proximal RCA (type 3) (4).
In our case there was type 2 variation.
Atrial septal pouch is a recess at atrium,
which is...
