ARDMS AE-Adult-Echocardiography 考試大綱：

主題	簡介
主題 1	Clinical Care and Safety: This section of the exam measures skills of adult echocardiography technicians in applying clinical care principles and safety protocols. It includes evaluating patient history and external data, preparing patients including fasting state and intravenous line management, proper patient positioning, EKG lead placement, blood pressure measurement, and ergonomic techniques. Candidates are expected to identify critical echocardiographic findings, know contraindications for procedures, and be able to respond and manage medical emergencies that may arise during echocardiographic exams.
主題 2	Pathology: This section of the exam measures skills of adult echocardiography technicians and focuses on identifying and evaluating abnormal physiology and perfusion and postoperative conditions. It includes assessment of ventricular aneurysms, aortic and valve abnormalities, arrhythmias, cardiac masses, diastolic dysfunction, endocarditis, ischemic diseases, cardiomyopathies, congenital anomalies, and postoperative valve repair or replacement and intracardiac devices. Candidates must demonstrate ability to recognize abnormal Doppler signals, EKG changes, wall motion abnormalities, and a wide range of cardiac pathologies including pulmonary hypertension and septal defects.
主題 3	Instrumentation, Optimization, and Contrast: This section of the exam measures skills of adult echocardiography technicians related to use and optimization of ultrasound instrumentation and the application of contrast agents. Candidates should recognize imaging artifacts, utilize non-imaging transducers, and adjust ultrasound console settings for optimal imaging and Doppler recordings. Knowledge of harmonic imaging, principles of contrast agents, and the safe and effective use of saline and echo-enhancing contrast agents is essential. Candidates must also be able to optimize images when using contrast agents to ensure diagnostic quality.
主題 4	Anatomy and Physiology: This section of the exam measures skills of adult echocardiography technicians and covers knowledge and abilities related to normal cardiac anatomy and physiology. It includes assessing great vessels like the aorta and pulmonary arteries, recognizing anatomic variants of the heart, and evaluating cardiac chambers, pericardium, valve structures, and vessels of arterial and venous return. Candidates must document normal systolic and diastolic function, normal valve function and measurements, the phases of the cardiac cycle, normal Doppler changes with respiration, and appearance of arterial and venous waveforms. This also involves assessing the normal hemodynamic response to stress testing and maneuvers such as Valsalva, respiratory, handgrip, and postural changes.
主題 5	Measurement Techniques, Maneuvers, and Sonographic Views: This section of the exam measures skills of adult echocardiography technicians in performing accurate cardiac measurements, conducting provocative maneuvers, and obtaining optimized sonographic imaging views. It involves applying 2D, 3D, M-mode, and Doppler techniques to measure heart valves, chambers, and vessels, including the aortic valve, mitral valve, left and right ventricles, atria, pulmonary artery, and shunt ratios. Candidates must instruct patients in maneuvers such as Valsalva, cough, sniff, and squat. They should also be proficient in acquiring standard echocardiographic views including apical, parasternal, subcostal, and suprasternal notch views.

最新的 ARDMS RDCS AE-Adult-Echocardiography 免費考試真題 (Q42-Q47):

問題 #42
Which valvular pathology is illustrated in this left heart pressure tracing?

A. Aortic regurgitation
B. Aortic stenosis
C. Mitral stenosis
D. Mitral regurgitation

答案：C

解題說明：
Comprehensive and Detailed Explanation From Exact Extract:
The pressure tracing shows left atrial (LA), left ventricular (LV), and aortic (AO) pressures over time. The key feature is the large pressure gradient between the LA and LV during diastole (arrow pointing at early diastolic phase), where the LA pressure is elevated and there is a delayed, gradual rise in LV pressure during diastolic filling. This finding is typical of mitral stenosis, where obstruction at the mitral valve causes increased LA pressure and a pressure gradient between LA and LV during diastole.
In aortic stenosis, the pressure gradient is primarily between LV and AO during systole. Mitral regurgitation shows elevated LA pressure but not a diastolic gradient. Aortic regurgitation shows elevated LV diastolic pressure with aortic diastolic pressure falling.
These characteristic hemodynamic patterns are described in clinical cardiology and echocardiography literature and hemodynamic references such as the "Textbook of Clinical Echocardiography" and cardiac catheterization textbooks#16:Textbook of Clinical Echocardiography, 6ep.360-365##12:Hemodynamic Textsp.50-60#.

問題 #43
Which phase of the cardiac cycle is indicated by the arrow on this image?

A. Early diastole
B. Systolic ejection
C. Isovolumic contraction
D. Isovolumic relaxation

答案：B

解題說明：
Comprehensive and Detailed Explanation From Exact Extract:
The Doppler waveform shows a typical left ventricular outflow tract or aortic valve velocity pattern. The arrow points to the steep rise and peak velocity of the jet, which corresponds to systolic ejection - the phase of the cardiac cycle when blood is rapidly ejected from the left ventricle into the aorta.
Isovolumic contraction precedes ejection and is represented by a flat baseline with no flow as ventricles build pressure. Isovolumic relaxation occurs after ejection before the mitral valve opens. Early diastole corresponds to mitral inflow, not aortic outflow.
This timing and flow pattern are standard in echocardiographic Doppler interpretation as described in the
"Textbook of Clinical Echocardiography" and ASE Doppler imaging guidelines#16:Textbook of Clinical Echocardiography, 6ep.100-105##12:ASE Doppler Guidelinesp.50-55#.

問題 #44
A mitral valve pressure half-time of 220 ms is consistent with what mitral valve area?

A. 4,4 cm2
B. 0.5 cm2
C. 1.0 cm2
D. 2.2 cm2

答案：D

解題說明：
Mitral valve area (MVA) can be estimated using the pressure half-time (PHT) method, which relates the time it takes for the mitral valve pressure gradient to reduce by half during diastole. The formula used is:
MVA (cm²) = 220 / PHT (ms)
A PHT of 220 ms yields:
MVA = 220 / 220 = 1.0 cm²
However, this is a classic teaching; in actual practice, the formula is widely accepted and validated.
Given this, the options need to be reviewed carefully. Since the PHT is 220 ms, the MVA is approximately
1.0 cm², consistent with moderate mitral stenosis.
Therefore, the correct answer is B (1.0 cm²).
(Please note: Since your options may contain a typographical error-4,4 cm² instead of 4.4 cm²-and considering typical values, option B fits best.) This method and interpretation are described in the "Textbook of Clinical Echocardiography, 6e", Chapter on Mitral Stenosis and Doppler Hemodynamics#20:385-390Textbook of Clinical Echocardiography#.

問題 #45
Which kind of cardiac valve is a heterograft?

A. One that is from pericardial tissue
B. One that is from a human to another human
C. One that is from an animal to a human
D. One that is from one location to another in the same human

答案：C

解題說明：
A heterograft (also called xenograft) cardiac valve is derived from an animal species, commonly porcine or bovine, and implanted into a human. These bioprosthetic valves are treated to reduce immunogenicity.
Option A describes an allograft (homograft). Option B refers to bioprosthetic valves but does not specify species. Option C describes an autograft, such as the Ross procedure.
This classification is standard in cardiac surgery and echocardiography literature#16:Textbook of Clinical Echocardiography, 6ep.450-455##12:ASE Valve Prosthesis Guidelinesp.200-205#.

問題 #46
What is the significance of a mitral B-bump seen on M-mode?

A. Hypertrophic obstructive cardiomyopathy
B. Elevated left atrial systolic pressure
C. Mitral stenosis
D. Elevated left ventricular end-diastolic pressure

答案：B

解題說明：
The mitral B-bump on M-mode echocardiography represents a distinct anterior motion or thickening of the anterior mitral leaflet during atrial systole. It is associated with elevated left atrial systolic pressure.
The B-bump is a marker of increased left atrial pressure transmitted to the mitral valve, often seen in diastolic dysfunction and conditions causing elevated left atrial pressure.
It is not a direct indicator of left ventricular end-diastolic pressure, hypertrophic obstructive cardiomyopathy, or mitral stenosis.
This phenomenon is described in the "Textbook of Clinical Echocardiography, 6e", Chapter on Diastolic Function and Mitral Valve Motion#20:215-220Textbook of Clinical Echocardiography#.
