(172 cards)
What is the crista terminalis
is a ridge of myocardium within the right atrium that extends along the posterolateral wall of the right atrium between the orifice of the superior vena cava to the orifice of the inferior vena cava
What is the ligamentum arteriosum aka** Botallo’s ligament **aka Harvery’s ligaement aka Botallo’s duct?
is a small ligament attaching the aorta to the pulmonary artery. It serves no function in adults but is the** remnant of the ductus arteriosus** formed within three weeks after birth
What is the eustachian valve
an embryologic remnant that lies at the junction of the inferior vena cava (IVC) and inferior right atrium (RA).
In fetal development, the valve directs incoming oxygenated blood towards the foramen ovale and away from the right atrium
What anatomical structure prevents blood from going back up the coronary veins when the right atria contracts?
the thesbian valve aka the coronary sinus
What is the triangle of Koch and what are the 3 deliminations?
Found in the Right atrium. Helps us find the AVN
Tendon of Todaro
Septal side of Tricuspid
Valve of tebesio
If you want to ablate the AVN (in case of pacemake implantation in A fib patients) you go into this triangle
Why is the auricle/appendage in the left atrium important?
90% of intracavitary thrombi form here
Virchow triad determines the likelihood of thrombi development. It includes
statis
hypercoagulability
endothelial damage
What is transposition of the greater vessels
is a congenital heart defect in which the position of the two major vessels that carry blood away from the heart, the aorta and the pulmonary artery, is switched
MUST OPERATE!!
What happens to the coronary circulation for the RV in systoli?
maintenence of circualtion (but note that the refilling of the vessel occurs in the diastolic phase)
What happens to the coronary circulation of the LV in systole?
decrease the circulation bc the muscle of the LV squishes the vessel
Where is the pulmonary trunk located with respect to the aorta?
infront of the aorta
What are the first and second most common valvulopathies?
1st: aortic stenosis
2nd: mitral insufficiency
another name for semilunar valves is (aortic/pulmonary)
sigmoid valves
which heart valve pathology has the highest risk of getting bacterial endocarditis?
bicuspid aortic valve
which condition has a higher likelihood of a person having a bicuspid aortic valve?
marfan syndrome
arteria coronaria sinistra gives the segno of valsalva sinistra
arteria coronaria destra gives the segno of valsalva destra
both signs of the valsalva are on the aortic valve
Which coronary artery is dominant
IVP - interventriculare posteriore aka discendente posteriore
which has an origin in the coronaria destra
whats the origin of the anterior interventricular artery? heart?
coronary sinistra
what is an absolute contradiction for coronagrophy
Nothing
If pt is allergic to iodinated contrast give cortisone and proceed
if pt has iper or ipothyroidism, schedule dialysis after proceedure but proceed
Coronary right
gives off the Interventricular posteriores (descenging postereior) which is for dominance
coronary left
has atrunoc commune then w2 branches. one with the interventrular anterior and the other is the circomflex artery
veins of the heart
coronary sinus (seno coronarico) - with valve names Tebesio
- vene cardiache anteriore o magna e parva
- vene minime di tebesio
Conduction system of the heart
sinoatrial node - 2 interatrial branches - join back at AVNode- split into bundle of Hiss then split into brnaca destra and sinistra (sinistra is bigger so it divides furhter into fascicolo anteriore and fascicolo posteriore)
do pacemaker cells have a fase di riposo?
no
