Oblique vein of the left atrium
Oblique vein of the left atrium
The Oblique vein of the left atrium, also known as Marshall's vein, is a small vessel in the heart that drains blood from the left atrium and empties into the coronary sinus. It is a remnant of the left superior vena cava which regresses during fetal development.
Structure[edit | edit source]
The oblique vein of the left atrium originates from the posterior part of the left atrium and courses obliquely downwards to join the coronary sinus near its right atrial orifice. It is typically 1-2 cm in length and is covered by a fold of serous pericardium, known as the vestigial fold of Marshall.
Function[edit | edit source]
The oblique vein of the left atrium serves to drain blood from the left atrium into the coronary sinus, which then empties into the right atrium. This helps to maintain the balance of blood flow within the heart.
Clinical significance[edit | edit source]
The oblique vein of the left atrium is of clinical significance as it can be a source of arrhythmias. It can also be used as a landmark during certain cardiac procedures, such as catheter ablation.
