The 6 intensities from highest to lowest are Correct Answer: 1.) SPTP 4.) SATP
2.)SPPA 5.) SAPA
3.)SPTA 6.) SATA
What tricuspid valve leaflets are noted in PLAX? Correct Answer: Anterior and medial/septal
posterior.
Formula for calculating EF? Correct Answer: EF% = (sv/edv) x 100%
Stroke Volume (SV) formula Correct Answer: EDV - ESV
What is stroke volume (SV)? Correct Answer: Amount of blood pumped out of each ventricle
during a single heart beat.
What is the chiari network? Correct Answer: Network of fibers originating from eustachian
valve.
Where can the chiari network be found Correct Answer: Right atria
What is the most anterior chamber of the heart? Correct Answer: Right ventricle
Which pair of intensities has the lowest value? Correct Answer: SATA (spatial average and
temporal average)
Where is the Eustachian valve located ? Correct Answer: In between the IVC and the right
atrium.
What's another name for the Right Ventricular Outflow Tract (RVOT) ? Correct Answer:
Infundibulum
Where is the coronary sinus located in relation to the descending aorta? Correct Answer:
Anterior
The three cusps of the tricuspid valve are? Correct Answer: Anterior
Medial
Posterior
,What's the two main layers of the pericardium? Correct Answer: 1.) Visceral = lies directly upon
external surface of the heart and is commonly referred to as the epicardium.
2,) Parietal = or fibrous pericardium is the thick outer sac.
*The pericardial cavity lies between these two layers.
What is the normal pressure for the right ventricle ? Correct Answer: 25/5 mmHg
What is the normal pressure for the pulmonary artery? Correct Answer: 25/10 mmHg
What is the normal pressure for the left atrium? Correct Answer: 10mmHg
What is the normal pressure for the aorta ? Correct Answer: 120/80 mmHg
What are the two cusps of the mitral valve ? Correct Answer: Anterior (long) and the posterior
(short)
When is the left ventricular pressure the lowest? Correct Answer: Early diastole
What is Becks Triad and what does it cause? Correct Answer: AKA cardiac tamponade. Causes
an elevated pressure in heart, hypotension and a quiet heart
What are the effects of pulmonary HTN ? Correct Answer: Dilated pulmonary artery
Severe TR
RV dilation
What happens to the size of an aneurysm during systole? Correct Answer: It increases
In patients with A-Fib which heart sound would be missing ? Correct Answer: Fourth
What is the normal O2 saturation of the left heart ? Correct Answer: 98%
What is cardiac output? Correct Answer: It is the total amount of blood ejected per minute.
*cardiac output = stroke volume x HR
*normal cardiac output = 4-8 liters/minute
Effects of left side heart failure Correct Answer: Blood backs up to lungs and patient has
shortness of breath
What part of the heart is affected when there is pulmonary edema ? Correct Answer: Left side of
heart
What is the primary cause of Congestive Heart Failure? Correct Answer: Systolic dysfunction.
What part of the heart is affected when there is peripheral edema? Correct Answer: Right side of
the heart
, When the foremen ovale closes after birth due to increased left atrial pressure the spot it was
located is now called? Correct Answer: Fossa ovalis
Mitral regurge hemodynamic evaluation is done in ? Correct Answer: Systole
Aortic stenosis evaluation is done in? Correct Answer: Systole
Tricuspid stenosis evaluation is done in ? Correct Answer: Diastole
What is Dresslers syndrome ? Correct Answer: Pericardial effusion after myocardial infarction
Is left atrial thrombus common in patients with mitral stenosis? Correct Answer: Yes, especially
in appendage
What are 3 factors affecting stroke volume? Correct Answer: Preload, after-load, contractility
What is fractional shortening? Correct Answer: It is the fraction of any diastolic dimension that
is lost in systole.
*normal range = 25-45%
If a patient has a stroke volume of 70ml and a heart rate of 90bpm what would be their cardiac
output? Correct Answer: Cardiac Output= Stroke volume x heart rate
70ml x 90bpm = 630ml/minute
What is QP and QS? Correct Answer: QP= pulmonary circulatory flow
QS= systemic circulatory flow
Atrial septal defect surgery is mainly considered when the QP/QS ratio exceed? Correct Answer:
1:5
*normal = 1:1
What are the 2 most common encountered congenital heart lesions diagnosed in adults ? Correct
Answer: Atrial septal defect
Bicuspid aortic valve
What chamber of the heart would be greater affected in patients with ventricular septal defects
and left to right shunting? Correct Answer: Right atrium
A patient with a higher blood pressure in the right arm than the left arm may have? Correct
Answer: Coarctation of aorta
How is a 2-d image of a phased array transducer created? Correct Answer: Sequentially
activating a series of adjacent crystals to angular the ultrasound beam
What is a heterograph/ xenograph? Correct Answer: Other names of bioprosthetic valves
transferred from animals to humans.
