Pulmonary Valve Anatomy unit 3 exam

For the Pulmonic Valve what is it Essentially identical to?

Essentially identical to the Aortic valve

Describe the Pulmonic Valve how does it sit anatomically in the heart and how is it to the aorta

The pulmonary valve is the most anterior valve of the heart and is superior to the aorta

Pulmonic Valve, opens during when the cardiac cycle?

Opens in systole

when does the Pulmonic Valve close and whats the purpose of this

Closes in diastole to prevent backwards flow

Where is the Pulmonic Valve located? ( between chambers)

Located between the right ventricle and pulmonary artery

How many cusps does the Pulmonic Valve have?

3 cusps

what are the Components of the Pulmonic Valve name 4

Annulus, cusps, commissures, interleaflet triangles

The Pulmonary Valve • how many and describe the shaped cusps:, and name each one

3 half moon shaped cusps: •

Anterior cusp • Left cusp • Right cusp

the Sinuses are named after what

Sinuses are named after cusps

Components and anatomy are the same as what valve, and name

Components and anatomy are the same as Aortic valve •

Nodule of Arantius •

Lunule

what does the Pulmonic root combines? name 5

1. Pulmonary valve leaflets •

2. Sinus of Valsalva (sinuses are named with leaflets) •

3. ST Junction (not as prominent as the aorta) •

4. Commissures •

5. Interleaflet triangles

The Pulmonic root is located how to the aortic valve?

Located anterior and to the left of the aortic valve

What are the Differences between aortic and pulmonic valve? (name 3)

1. TV and PV are separated by infundibular muscle •

2. The pulmonary leaflets are not supported by the IVS. •

3. Typically we only visualize the right and anterior cusps during an echocardiogram in PSAX

The main pulmonary artery lies how to the aorta and branches into what?

The main pulmonary artery lies anterior to the aorta and branches into the right and left pulmonary arteries

The branches of the PA what size?

The branches are equal in size

The Pulmonic Valve is obtained in what view, with what o’clock rotation of the probe?

Obtained in PSAX with a 4-5 o’clock rotation of the probe
