Cardiac Anatomy
Exam 1
| Question | Answer |
|---|---|
| What makes up the RVOT? | blood exiting the right ventricle through the pulmonic valve to the pulmonary artery |
| What makes up RVIT? | blood exiting the right atrium through the tricuspid valve into the right ventricle |
| What makes up the LVOT? | blood exiting the left ventricle through the aortic valve into the aorta |
| What makes up the LVIT? | blood exiting the left atrium through the mitral valve into the left ventricle |
| What valves are closed during systole? | AV valves (tricuspid & mitral) |
| What valves are closed during diastole? | Semilunar valves (pulmonic & aortic) |
| What's the thin oval region in the right atrium? | fossa ovalis |
| What is located at the superior portions of the atria? | left & right atrial appendages or auricles |
| Which ventricle is more trabeculated? | right |
| What will you only see in the right atrium? | crista supraventricularis and parietal, septal, & moderator bands, as well as Eustachian valve, Thebesian valve, & coronary sinus |
| What are the parts of the mitral valve? | anterior & posterior mitral valve leaflets |
| What are the parts of the tricuspid valve? | anterior, inferior/posterior, & septal valve leaflets |
| Where do leaflets of mitral valve attach? | mitral valve annulus |
| What are the parts of the aortic valve? | left, right, & non-coronary cusps |
| What measurements are taken in the aortic root? | sinus of Valsalva, sino-tubular junction, & ascending aorta |
| What arises from the sinus of Valsalva? | left & right Coronary arteries |
| What are the parts of the pulmonic valve? | anterior, right, & left pulmonary valve cusps |
| What does the left main coronary artery branch into? | left anterior descending (LAD) & left circumflex (LCX) |
| What does the right main coronary artery branch into? | right posterior descending (RPD), right marginal, & nodal artery |
| What structure is usually seen in the right ventricle? | moderator band |
| This valve is more inferiorly attached to the IVS? | tricuspid valve |
| The aortic arch is best seen from this window? | suprasternal |
| This window is used to view & measure the IVC: | subcostal |
| What is the valve of the coronary sinus? | Thebesian valve |
| A congenital remnant seen in the right atrium: | chiari network |
| the superior portion of each atrium: | appendage |
| This measure low velocity & high amplitude: | tissue doppler |
| The NCC intersects with the structure: | IAS |
| LV measurements are made at this level from the PLAX view: | chordal level |
| What artery courses under the aortic arch? | right pulmonary artery |
| What vein is seen from the SSN that may be confused for a dissection of the aortic arch? | left innominate vein |
| In the PLAX view, the IVS runs continuous with the: | anterior aortic root |
| What runs continuous with the AMVL? | posterior aortic root |
| This valve may be seen at the basal LV PSAX level: | mitral valve |
| This represents ventricular depolarization on an EKG: | QRS |
| Doppler assessment of both the PV & TV can be interrogated from this view: | PSAX |
| Which echo modality has the greatest temporal resolution? | M-Mode |
| This represents atrial depolarization on an EKG: | P wave |
| This represents ventricular repolarization on an EKG: | T wave |
