NO.25 During which phase of the cardiac cycle does the left ventricular filling pressure equalize with left atrial pressure?

Early rapid filling

Ventricular contraction

Atrial contraction

Diastasis

During early rapid filling, when the mitral valve opens at the onset of diastole, the pressure gradient between the left atrium (LA) and left ventricle (LV) is at its peak, allowing blood to flow into the ventricle. As filling progresses during this phase, the left ventricular diastolic pressure rises rapidly and quickly approaches and equalizes with left atrial pressure.
The equalization of pressures is critical to facilitate ventricular filling and is reflected in the mitral inflow Doppler pattern, where the E-wave corresponds to early rapid filling. Diastasis is the mid-diastolic slow filling phase where pressures are nearly equal and little flow occurs. Atrial contraction is the late filling phase, adding a small volume to the ventricle.
This physiological timing is detailed in the “Textbook of Clinical Echocardiography, 6e”, Chapter on Diastolic Function and Hemodynamics, with emphasis on pressure changes during the cardiac cycle#20:210-
215Textbook of Clinical Echocardiography#.

NO.26 Which kind of cardiac valve is a heterograft?

One that is from a human to another human

One that is from pericardial tissue

One that is from one location to another in the same human

One that is from an animal to a human

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#.

NO.27 Which hepatic vein flow pattern signals severe tricuspid regurgitation?

Flow reversal in systole

Flow reversal in diastole

Atrial flow reversal in systole

Biphasic flow reversal in diastole

In severe tricuspid regurgitation (TR), the regurgitant jet flows back from the right ventricle into the right atrium during systole, causing reversal of flow in the hepatic veins during the same phase. On Doppler echocardiography, this manifests as systolic flow reversal in the hepatic veins, which is a hallmark sign of severe TR.
Normally, hepatic vein flow consists of a predominant systolic forward flow into the right atrium. However, in severe TR, the high pressure in the right atrium during systole causes retrograde flow in the hepatic veins.
This pattern is diagnostic and aids in severity assessment.
Diastolic flow reversal is uncommon in TR and more associated with other pathologies. Atrial flow reversal in systole or biphasic flow reversal in diastole are not recognized patterns for severe TR.
This is described in detail in the “Textbook of Clinical Echocardiography, 6e”, Chapter on Right Heart and Tricuspid Valve Disease, with Doppler patterns illustrated for hepatic vein flow in tricuspid regurgitation#20:
330-335Textbook of Clinical Echocardiography#.

NO.28 Which finding is demonstrated in this video?

Bioprosthetic valve replacement

Mechanical valve replacement

Annuloplasty ring repair

Native valve with extensive calcification

The echocardiographic video shows a prosthetic ring-like structure attached to the mitral annulus with preserved native leaflet motion, consistent with an annuloplasty ring repair. Annuloplasty rings are used to reduce the mitral annulus size and improve leaflet coaptation in mitral regurgitation without replacing the valve.
Bioprosthetic or mechanical valve replacements would show distinctly different echogenic valve structures with leaflet or disc motion replacing the native valve. Extensive calcification of a native valve appears as echogenic, thickened leaflets without a discrete ring.
This is described in the “Textbook of Clinical Echocardiography, 6e”, Chapter on Mitral Valve Repair Techniques#20:400-405Textbook of Clinical Echocardiography#.

NO.29 Which view is best for assessing atrial situs in the presence of congenital heart disease?

Subcostal

Short axis

Long axis

Suprasternal notch

The subcostal view is the preferred transthoracic echocardiographic window to assess atrial situs, especially in congenital heart disease. This view provides a cross-sectional look at the abdominal organs and atrial chambers, helping determine the relative position of the inferior vena cava and aorta, which aids in defining atrial situs (solitus, inversus, or ambiguous).
Short axis and long axis views provide excellent cardiac anatomy but are less informative for visceral situs.
The suprasternal notch window is mainly used to visualize the great vessels but does not provide adequate assessment of atrial situs.
The subcostal view’s ability to demonstrate abdominal situs and systemic venous return makes it essential in congenital cardiac evaluations and is recommended in echocardiography protocols for congenital heart disease assessment .

NO.30 What is the range of the aortic valve area in normal adults?

1 – 2 cm2

7- 8cm2

5 – 6cm2

3 – 4cm2

Comprehensive and Detailed Explanation From Exact Extract:
The normal aortic valve area (AVA) in adults typically ranges from 3 to 4 cm². This measurement is important for assessing aortic stenosis severity; values below this range suggest valve narrowing.
AVA values of 1-2 cm² indicate mild to moderate stenosis, while less than 1 cm² reflects severe stenosis.
Larger areas like 5-6 or 7-8 cm² are not physiologically typical.
This normal range is documented in the “Textbook of Clinical Echocardiography, 6e”, Chapter on Aortic Valve Anatomy and Function#20:360-365Textbook of Clinical Echocardiography#.

NO.31 Which adjustment should be made to optimize this video?

Increase compression

Decrease overall gain

Increase time gain compensation in the near field

Decrease time gain compensation in the far field

The echocardiographic image/video shows decreased brightness and penetration in the near field, making the anterior cardiac structures poorly visualized while deeper structures appear brighter. This indicates under-gain in the near field.
Increasing the time gain compensation (TGC) in the near field enhances the signal strength of superficial structures without affecting deeper tissues. This adjustment improves image quality by balancing the brightness across the field.
Increasing compression or decreasing overall gain would reduce the signal globally and are not specific for near field optimization. Decreasing TGC in the far field would reduce brightness deeper but does not address near-field issues.
This principle is outlined in the “Textbook of Clinical Echocardiography, 6e”, Chapter on Image Optimization and Technical Settings#20:70-75Textbook of Clinical Echocardiography#.

NO.32 Which procedure is most appropriate for evaluation of an atrial septal defect in the presence of an atrial septal aneurysm?

Cardiac MRI

Cardiac catheterization

Agitated saline contrast echocardiogram

Transesophageal echocardiogram

Transesophageal echocardiography (TEE) provides superior visualization of the atrial septum, especially in the presence of an atrial septal aneurysm, which may obscure transthoracic views. TEE allows detailed anatomic assessment of the atrial septal defect (ASD), its size, and associated structures.
Agitated saline contrast echo is useful for detecting right-to-left shunts but is limited in anatomical delineation in complex cases. Cardiac MRI and catheterization can provide complementary information but are not first- line for ASD evaluation when TEE is available.
ASE adult congenital heart disease guidelines and echocardiography texts emphasize TEE as the gold standard for ASD evaluation in this setting#12:ASE Adult Congenital Guidelinesp.405-410##16:Textbook of Clinical Echocardiography, 6ep.570-575#.

NO.33 Which Doppler signal is used to calculate the pulmonary artery end-diastolic pressure gradient?

Tricuspid insufficiency

Tricuspid inflow velocity

Pulmonary insufficiency

Pulmonary inflow velocity

Pulmonary artery end-diastolic pressure (PAEDP) can be estimated noninvasively by measuring the end- diastolic velocity of pulmonary regurgitation (pulmonary insufficiency) using continuous-wave Doppler. The pressure gradient between the pulmonary artery and right ventricle at end-diastole is calculated using the modified Bernoulli equation from this velocity.
Tricuspid insufficiency is used to estimate right ventricular systolic pressure. Tricuspid inflow and pulmonary inflow velocities provide information on diastolic function but not direct pressure gradients.
This method is well validated and included in ASE guidelines for pulmonary hypertension assessment and Doppler hemodynamics#16:Textbook of Clinical Echocardiography, 6ep.300-305##12:ASE Doppler Guidelinesp.110-115#.

NO.34 Which adjustment will improve the frame rate?

Narrow sector width

Decrease overall gain

Increase dynamic range

Increase transducer frequency

Frame rate in echocardiography is affected by the sector width, depth, and line density. Narrowing the sector width reduces the number of scan lines per frame, thus increasing the frame rate and temporal resolution. This improves the ability to capture rapid cardiac motion.
Decreasing overall gain affects image brightness, not frame rate. Increasing dynamic range increases the number of gray shades, which may slightly decrease frame rate due to processing load. Increasing transducer frequency improves resolution but reduces penetration depth and can decrease frame rate due to longer pulse duration.
This principle is emphasized in echocardiography physics and instrumentation texts and ASE imaging guidelines#16:Textbook of Clinical Echocardiography, 6ep.40-45##12:ASE Imaging Protocolsp.10-15#.

NO.35 Based on this video, what is the estimated right atrial pressure in millimeters of mercury (mmHg)?

Comprehensive and Detailed Explanation From Exact Extract:
The video shows a subcostal IVC view with measurement of IVC diameter and respiratory collapsibility. The IVC appears dilated (>2.1 cm) with less than 50% collapse on inspiration, suggesting elevated right atrial pressure (RAP).
According to ASE guidelines for noninvasive RAP estimation, an IVC diameter >2.1 cm with <50% collapsibility corresponds to an RAP of approximately 10 mmHg.
Lower RAP values correspond to smaller IVC and greater collapsibility. This is a standard measurement in adult echocardiography practice and ASE chamber quantification guidelines#12:ASE Chamber Quantification Guidelinesp.80-85##16:Textbook of Clinical Echocardiography, 6ep.115-120#.

NO.36 Which type of valvular lesion most commonly requires further evaluation with a non-imaging transducer?

Aortic stenosis

Mitral regurgitation

Tricuspid regurgitation

Pulmonic stenosis

Aortic stenosis (AS) is the valvular lesion most commonly requiring evaluation with a non-imaging (pedoff) continuous wave Doppler transducer. This specialized probe allows the operator to align the Doppler beam parallel to high-velocity aortic jets to accurately measure peak and mean gradients across the stenotic aortic valve.
While imaging Doppler can estimate gradients, non-imaging CW Doppler is essential for precise quantification, especially in difficult acoustic windows or when maximal velocities need to be captured.
Mitral and tricuspid regurgitations and pulmonic stenosis are typically assessed with imaging transducers, as jet orientation is more variable.
This is highlighted in the “Textbook of Clinical Echocardiography, 6e”, Chapter on Doppler Hemodynamics and Valvular Stenosis Assessment#20:310-315Textbook of Clinical Echocardiography#.

NO.37 What is the significance of a mitral B-bump seen on M-mode?

Elevated left atrial systolic pressure

Elevated left ventricular end-diastolic pressure

Hypertrophic obstructive cardiomyopathy

Mitral stenosis

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#.

NO.38 Which finding is most consistent with this M-mode image?

Rheumatic mitral stenosis

Mitral valve prolapse

Mitral valve annuloplasty ring

Systolic antenor motion of the mitral valve

Comprehensive and Detailed Explanation From Exact Extract:
This M-mode echocardiographic image shows thickened mitral valve leaflets with a characteristic “doming” or “hockey-stick” appearance during diastole, which is classic for rheumatic mitral stenosis. Rheumatic mitral stenosis leads to leaflet thickening, restricted opening, and calcification, which alters the normal mitral valve motion on M-mode.
Mitral valve prolapse would show systolic displacement of the leaflets into the left atrium, typically later in systole, not doming in diastole. Mitral valve annuloplasty ring would appear as a bright echogenic line around the annulus but is not seen in this image. Systolic anterior motion (SAM) of the mitral valve is usually seen in hypertrophic cardiomyopathy and presents as anterior motion during systole, not the diastolic pattern shown.
This classical M-mode appearance is described in “Textbook of Clinical Echocardiography, 6e”, Chapter on Rheumatic Valve Disease#20:385-390Textbook of Clinical Echocardiography#.

NO.39 Which of the following are key features of an unrepaired tetralogy of Fallot?

Displaced tricuspid valve, atrialization of the right ventricle, severe tricuspid regurgitation, and a secundum atrial septal defect

Supravalvular mitral valvular ring, subaortic membrane, bicuspid aortic valve, and aortic coarctation

Inlet ventricular septal defect, common atrioventricular valve, atrioventricular valve regurgitation, and primum atrial septal defect

Outlet ventricular septal defect, overriding aorta, right ventricular outflow tract obstruction, and right ventricular hypertrophy

Comprehensive and Detailed Explanation From Exact Extract:
Tetralogy of Fallot (TOF) is a congenital heart defect characterized by four key anatomical abnormalities: an outlet (malalignment) ventricular septal defect (VSD), an overriding aorta that receives blood from both ventricles, right ventricular outflow tract (RVOT) obstruction (commonly infundibular stenosis), and resultant right ventricular hypertrophy. These defects cause cyanosis due to right-to-left shunting and impaired pulmonary blood flow.
Option A describes Ebstein anomaly, characterized by a displaced tricuspid valve and atrialization of the right ventricle.
Option B describes features more consistent with Shone complex or other left heart obstructive lesions.
Option C describes atrioventricular septal defect (AVSD), seen in conditions like Down syndrome.
In unrepaired TOF, echocardiography demonstrates the large malalignment VSD, overriding aorta, RVOT obstruction, and hypertrophied right ventricle. These are classic textbook findings described in adult and pediatric echocardiography literature, including “Textbook of Clinical Echocardiography” (Chapter on Congenital Heart Disease) and ASE guidelines#16:Textbook of Clinical Echocardiography, 6ep.560-565#
#12:ASE Adult Congenital Guidelinesp.400-410#.

NO.40 Which finding does peak mitral valve regurgitant Doppler velocity reflect?

Severity of regurgitation

Pressure gradient between the left ventricle and aorta

Mechanism of regurgitation

Pressure gradient between the left ventricle and left atrium

The peak Doppler velocity of mitral regurgitation (MR) reflects the instantaneous pressure gradient between the left ventricle (LV) and left atrium (LA) during systole. The higher the velocity, the greater the pressure difference.
However, the velocity itself does not quantify severity directly; severity depends on the size and volume of the regurgitant jet. The mechanism is determined by valve morphology and motion, not velocity. The LV to aorta gradient relates to aortic valve pathology.
This principle is discussed in the “Textbook of Clinical Echocardiography, 6e”, Chapter on Mitral Regurgitation and Doppler Evaluation#20:390-395Textbook of Clinical Echocardiography#.

NO.41 A continuous flow murmur is most likely due to which abnormality?

Ventricular septal defect

Patent ductus arteriosus

Concomitant aortic stenosis and mitral regurgitation

Ebstein anomaly with atrial septal defect

A continuous murmur, heard throughout systole and diastole, is most characteristically caused by a patent ductus arteriosus (PDA). PDA represents persistent communication between the aorta and pulmonary artery, allowing continuous blood flow during both phases of the cardiac cycle.
Ventricular septal defect usually produces a holosystolic murmur. Concomitant aortic stenosis and mitral regurgitation cause separate murmurs but not continuous. Ebstein anomaly with atrial septal defect typically produces murmurs related to tricuspid regurgitation or ASD but not a continuous murmur.
This clinical correlation is detailed in the “Textbook of Clinical Echocardiography, 6e”, Chapter on Congenital Heart Disease and Murmur Etiologies#20:420-425Textbook of Clinical Echocardiography#.

NO.42 Which diagnosis is most likely confirmed by echocardiography in a 65-year-old female presenting with new onset chest pain associated with ST segment elevation on the electrocardiogram and angiographically normal coronary artenes?

Alcohol-associated cardiomyopathy

Apical hypertrophic cardiomyopathy

Restrictive cardiomyopathy

Takotsubo cardiomyopathy

Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy or “broken heart syndrome,” predominantly affects postmenopausal women (usually older than 50 years) and often presents with acute chest pain and ST-segment elevation on the ECG mimicking acute myocardial infarction. However, coronary angiography reveals normal or non-obstructive coronary arteries.
Echocardiographically, Takotsubo cardiomyopathy is characterized by transient left ventricular systolic dysfunction with a typical pattern of apical ballooning and basal hyperkinesis. The wall motion abnormality extends beyond a single coronary artery territory, differentiating it from ischemic cardiomyopathy.
The diagnosis is supported by the clinical presentation, typical echocardiographic findings, and exclusion of obstructive coronary artery disease. The condition is usually reversible over days to weeks.
This is extensively described in the “Textbook of Clinical Echocardiography, 6e” (Chapter 8: Coronary Artery Disease and Takotsubo Syndrome), which highlights the typical patient demographics, presentation, echocardiographic features, and prognosis .
