Advances in CHD Corrective Flashcards
What is Cardioplegia?
The intentional and temporary cessation of the heart, to produce asystole.
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.
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.
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
Name two types of valves used for replacements:
Prosthetic/mechanical valves
Tissue valves: bovine or porcine
What is levocardia?
Normal position of the heart.
What is dextrocardia?
Location of the heart in the right side of the thorax, apex pointing to the right.
What is mesocardia?
Atypical location of the heart with the apex in the midline of the thorax.
What is concordance?
Normal chamber attachments and normal anatomy.
What is discordance?
Abnormal chamber attachment.
What is cardiac situs?
Normal cardiac position within the thorax.
What is atrial situs?
Normal atria positioning.
What is situs inversus?
Heart is positioned in the right side of the thorax and reversed, or mirrored.
What is dextroposition?
The heart is displaced to the right side of the thorax with apex pointing to the left.
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.
