1

What is Cardioplegia?

The intentional and temporary cessation of the heart, to produce asystole.

2

Where is the specialized cardioplegia solution introduced and why?

Into the coronary circulation.
To slow the metabolism of the heart and prevent damage to the LV and RV myocardium, to protect the tissue.

3

When are septal occluders used and where is the procedure performed?

They close septal defects, PDA or PFO.
Procedure is done in the Cath lab.

4

Which septal defect does not produce a loud murmur and so is sometimes not detected until patient is symptomatic and in their 20's or 30's?

Atrial Septal Defect: ASD

5

Name two types of valves used for replacements:

Prosthetic/mechanical valves
Tissue valves: bovine or porcine

15

What is dextroversion?

The heart is displaced to the right side of the thorax, apex pointing to the right, without mirror transposition of the cardiac chambers.

16

What is mirror image dextrocardia?

Another name for situs inversus where the heart is positioned to the right side of the thorax and chambers are reversed/mirrored.
