Presentation
Unspecific chest pain. Positive stress ECG.
Patient Data
Coronary CTA shows an anomalous origin of the left coronary artery from the right coronary sinus (common ostium with the right coronary artery) and a subpulmonic course of the short left main stem. Early bifurcation with a long transseptal course of the thin left anterior descending artery (LAD) and subpulmonic course of the circumflex artery.
No coronary calcifications or visible plaques.
Case Discussion
A case of a left coronary artery anomaly with anomalous origin from the right coronary sinus (single ostium together with the right coronary artery) a long transseptal course of the thin left anterior descending artery and a subpulmonic course of the left main stem and the circumflex artery.
In the absence of any significant coronary plaques, the unspecific chest pain and the positive ECG stress test result can be best explained by dynamic compression of the proximal transseptal segment of the left anterior descending artery.
The patient was then transferred to the cath lab for further investigations.
