AOV Anatomy Flashcards
The “normal” AOV has how many cusps?
Three.
Apart from being tricuspid, the AOV can also be what?
Bicuspid, Unicuspid or Quadricuspid.
What are the Sinuses of Valsalva?
An expanded region, upstream of the AOV, from which the coronary arteries originate.
The AOV cusps are named according to their relationship with the coronary arteries; what are they?
Right, Left and Non.
The right coronary cusp lies adjacent to the Sinus giving rise to which coronary artery?
The RCA.
The left coronary cusp lies adjacent to the Sinus giving rise to which coronary artery?
The left coronary artery.
Why is the non coronary cusp named that way?
As it lies adjacent to the third Sinus that does not have a coronary artery.
The point where adjacent cusps meet is called what?
A commissure.
Each cusp has a small nodule at its centre on the free edge, called what?
The nodule of Arantius.
The nodule of Arantius is more prominent in which population?
The elderly.
The ventricular surface of the cusps often carry small mobile filaments called what?
Lambl’s excrescences.
True or False; Lambl’s excrescences are of no clinical significance.
True.
Lambl’s excrescences should not be mistaken for what?
Vegetations or papillary fibroelastomas.
In the PLAX view, which AOV cusps are visualised?
The right and non coronary cusps.
In the PSAX view, which AOV cusps are visualised?
All of them (Ronny Loves Nancy).
The blind/pencil probe is also referred to as what?
A pedoff probe.
In the apical 3-chamber view, which AOV cusps are visualised?
The right and non coronary cusps.
