- B.
Ebstein's anomaly
- C.
Wolff-Parkinson-White syndrome
- D.
Dextrocardia
Correct Answer
C. Wolff-Parkinson-White syndromeExplanation
Wolff-Parkinson-White syndrome is the correct answer because it is a condition characterized by the presence of an extra electrical pathway between the atria and ventricles. This pathway, called the Bundle of Kent, bypasses the normal electrical conduction system of the heart and causes rapid heartbeat or tachycardia. This can lead to symptoms such as palpitations, dizziness, and shortness of breath. Treatment options for Wolff-Parkinson-White syndrome may include medications, catheter ablation, or surgery to remove the abnormal pathway.Rate this question:

Which of the following is NOT a cause of cardiac enlargement?
- A.
Errors of metabolism
- B.
Endocardial fibroelastosis
- C.
Exposure to virus
- D.
Cardiac shunts
Correct Answer
B. Endocardial fibroelastosisExplanation
Ventricular shunts, such as large ventricular septal defects (VSDs), can cause dilatation of the heart. This occurs because the abnormal opening between the left and right ventricles leads to increased blood flow from the left ventricle to the right ventricle. Initially, this increased workload causes left-sided enlargement. Over time, the right side of the heart may also dilate due to the increased volume of blood being pumped into the pulmonary circulation. In contrast, endocardial fibroelastosis is characterized by thickening of the endocardium, the inner lining of the heart chambers. While this condition can impair the heart's ability to relax and fill with blood properly, it does not typically cause dilatation of the heart chambers. Instead, it primarily leads to thickening of the heart chambers' lining, which can ultimately result in heart failure due to impaired ventricular function.Rate this question:

The correct answer is "muscular." In the explanation, it can be stated that defects that lie below the crista (a ridge of tissue) are known as infracristal defects. These defects can be found in the muscular part of the septum. The other options, inlet and subarterial, do not specifically refer to the location of the defects, making them incorrect choices.Rate this question:

Membranous defects may be partially covered by ___________
- A.
Tricupid anterior leaflet
- B.
Tricuspid septal leaflet
- C.
Non aortic cusp
- D.
Right aortic cusp
Correct Answer
B. Tricuspid septal leafletExplanation
Membranous defects in the heart can sometimes be partially covered by the tricuspid septal leaflet. The tricuspid septal leaflet is one of the three leaflets that make up the tricuspid valve, which separates the right atrium from the right ventricle. When there is a defect in the membranous portion of the ventricular septum, the tricuspid septal leaflet may extend and partially cover the defect, providing some degree of closure. This helps prevent abnormal blood flow between the right atrium and right ventricle, improving overall cardiac function.Rate this question:

Four chamber view of VSD you must sweep:
- A.
Right to left
- B.
Left to right
- C.
Superior to inferior
- D.
Posterior to anterior
Correct Answer
D. Posterior to anteriorExplanation
The correct answer is "posterior to anterior." In a four-chamber view of a ventricular septal defect (VSD), the ultrasound probe is swept from the posterior (back) to the anterior (front) direction. This allows for a comprehensive assessment of the VSD and its location within the heart. By starting from the posterior aspect and moving towards the anterior aspect, the examiner can visualize the entire VSD and accurately assess its size and characteristics.Rate this question:

VSD may close with the formation of __________ tissue, which is found along the ____ side of defect
- A.
Aneurysm, left
- B.
Muscle, left
- C.
Muscle, right
- D.
Aneurysm, right
Correct Answer
D. Aneurysm, rightExplanation
VSD stands for Ventricular Septal Defect, which is a hole in the wall separating the two lower chambers of the heart. When a VSD closes, it can form an aneurysm, which is a bulge in a blood vessel caused by weakness in the vessel wall. In this case, the aneurysm would be found along the right side of the defect.Rate this question:

Aneruysms generally protrude into right heart in one of three directions:
- A.
Below the tricuspid valve and into the RA, directly into the septal leaflet of TV, below the TV into right ventricular cavity
- B.
Above the tricuspid valve and into the RA, directly into the septal leaflet of TV, below the TV into right ventricular cavity
- C.
Below the tricuspid valve and into the RA, directly into the anterior leaflet of TV, below the TV into the right ventricular cavity
- D.
Above the tricuspid valve and into the RA, directly into the posterior leaflet of TV, below the TV into right ventricular cavity
Correct Answer
B. Above the tricuspid valve and into the RA, directly into the septal leaflet of TV, below the TV into right ventricular cavity -

Small muscular defects often close spontaneously
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Small muscular defects often close spontaneously, meaning that they can heal on their own without any intervention or treatment. This is true because the body has the ability to repair small defects in muscles through natural healing processes. These defects may be caused by various factors such as injury or strain, and the body's natural healing mechanisms can effectively close them over time. However, it is important to note that larger or more severe muscular defects may require medical intervention or surgical procedures to facilitate proper healing.Rate this question:

May be small or large or be with multiple fenestrated holes
- A.
Muscular
- B.
Inlet
- C.
Subarterial
- D.
Perimembranous
Correct Answer
A. MuscularExplanation
The given answer "muscular" suggests that the structure being described may have muscle tissue. This implies that it is likely a muscular structure, which could be found in various sizes and may have multiple fenestrated holes. The other options provided (inlet, subarterial, perimembranous) do not provide any information about the structure's characteristics or composition, making them less likely to be the correct answer.Rate this question:

Incomplete ASD is a failure of:
- A.
Blood moving from right to left
- B.
To be seen on echo
- C.
Endocardial cushion to fuse
- D.
Valve formation
Correct Answer
C. Endocardial cushion to fuseExplanation
Incomplete ASD refers to a condition where the endocardial cushion, which is responsible for the fusion of the heart valves, fails to fully close. This can result in a communication between the right and left atria of the heart, allowing blood to flow from the right side to the left side. This defect can be detected through an echocardiogram, a non-invasive imaging technique used to visualize the heart's structures and blood flow.Rate this question:
