Great cardiac vein variations

Area of Science:

• Anatomy
• Cardiovascular Science
• Embryology

Background:

• Variations in the great cardiac vein's course are not extensively studied.
• Common variations involve its relationship with the anterior interventricular and circumflex arteries.
• A novel intertwined relationship between the great cardiac vein and circumflex artery was observed.

Purpose of the Study:

• To document and describe a rare, intertwined anatomical variation between the great cardiac vein and circumflex artery.
• To review known variations of the great cardiac vein.
• To discuss potential implications of this variation.

Main Methods:

• Observation of a unique anatomical variation in a cadaver heart.
• Detailed description of the spatial relationship between the great cardiac vein and circumflex artery.
• Literature review of existing great cardiac vein variations.

Main Results:

• A novel case where the great cardiac vein and circumflex artery were intertwined, each looping around the other.
• This variation was observed in an otherwise normal heart and not associated with pathology.
• Existing literature primarily describes simpler variations in vessel proximity or crossing.

Conclusions:

• The observed intertwined vascular variation is rare and unique.
• This finding may offer insights into vasculo-angiogenesis mechanisms.
• Clinical relevance for coronary sulcus procedures and surgeries is suggested.
