The circumflex artery, which branches off from the left main artery, runs along the atrioventricular groove around the left atrium, giving rise to left marginal branches in the process.
Caption: FIGURE 4: Axial contrast-enhanced CT image of the chest shows nodular soft tissue thickening overlying the right atrium posteriorly (arrow) and extending to the atrioventricular groove (arrowhead).
In conclusion, we report a very rare case of cardiac hemangioma located on the left atrioventricular groove. Surgical excision of tumor mass had a favorable outcome.
The great cardiac vein and the coronary sinus were commonly embedded in the subepicardial fat of the posterior atrioventricular groove. The coronary sinus as it passed to the right deviated slightly superiorly to become more related to the back of the left atrium before it coursed inferiorly to open into the right atrium.
