Oblique vein of the left atrium
The oblique vein of the left atrium (oblique vein of Marshall) is a small vessel which descends obliquely on the back of the left atrium and ends in the coronary sinus near its left extremity; it is continuous above with the ligament of the left vena cava (lig. venæ cavæ sinistræ vestigial fold of Marshall), and the two structures form the remnant of the left Cuvierian duct. This obscure region of cardiac perfusion adjacent to the SA node rocks back and forth under systole and diastole thus further influencing cardiac autonomic innervation. Ablation of this channel seems reasonable to many observers.

gollark: They have somewhat good reasons to be 32-bit because they want one image for all Pis (except 4s now)?
gollark: Yes.
gollark: Or at least is for RPi3Bs or something?
gollark: Yep! Raspbian is indeed 32-bit.
gollark: Mine runs Void, which is 64-bit on it.
