25
Are Papillary Fibroelastomas often symptomatic or asymptomatic?
Often incidental finding; many are clinically silent ## Footnote They can result in emboli such as stroke.
26
What potential complication can arise from Papillary Fibroelastomas?
Emboli (stroke) ## Footnote This can occur even if the tumor is clinically silent.
27
What is the main treatment option for Papillary Fibroelastomas?
Anticoagulation and surgical excision ## Footnote These treatments help manage the risks associated with the tumor.
28
What is Lipomatous Hypertrophy of the IAS?
The result of the accumulation of excess adipose tissue within the IAS with sparing of the fossa ovalis membrane ## Footnote Lipomatous Hypertrophy typically occurs in the interatrial septum.
29
What are the characteristic appearances of Lipomatous Hypertrophy of the IAS?
Characteristic 'dumbbell' or 'hourglass' appearance ## Footnote These shapes are indicative of the distribution of adipose tissue.
30
What are Rhabdomyomas?
Most common benign tumor in children ## Footnote Rhabdomyomas are primarily found in the heart and are associated with various conditions.
31
What condition is strongly associated with Rhabdomyomas?
Tuberous sclerosis ## Footnote Tuberous sclerosis is a genetic disorder that causes noncancerous tumors to form in many different organs.
32
Where are Rhabdomyomas typically found?
In the ventricular walls, especially the right ventricle ## Footnote This location is critical as it can influence heart function.
33
Are Rhabdomyomas usually singular or multiple?
Usually multiple tumors ## Footnote The presence of multiple tumors can complicate diagnosis and treatment.
34
What potential complication can Rhabdomyomas cause?
Outflow tract obstruction ## Footnote This obstruction can lead to significant cardiovascular issues depending on the severity.
35
What type of tumors are more common than primary malignant tumors?
Non-Primary Metastatic Tumors
36
From which organs do non-primary metastatic tumors most frequently travel?
They most frequently travel from lung, breast, kidney, liver, lymph nodes, and melanoma
37
How do non-primary metastatic tumors spread?
They spread by lymphatic channels, direct venous extension, or through biologically active substances (Carcinoid)
38
What is the most commonly affected area by non-primary metastatic tumors?
The pericardium
39
True or False: Non-primary metastatic tumors can only affect the heart.
False
40
Fill in the blank: Non-primary metastatic tumors may also be _______.
extracardiac
41
What percentage of primary malignant tumors do sarcomas represent?
28%
42
What is angiosarcoma associated with?
RA or pericardium
43
Osteosarcoma is primarily located in which area?
LA
44
What percentage of primary malignant tumors does rhabdomyosarcoma account for?
11%
45
What percentage of primary malignant tumors does fibrosarcoma represent?
8%
46
What are 2D artifacts in ultrasound?
Ultrasound may produce artifacts that give the appearance of masses within the heart. ## Footnote Artifacts can mislead interpretations and require careful analysis.
47
Can most ultrasound artifacts be resolved?
Yes, most artifacts can be resolved. ## Footnote Understanding how to address artifacts is essential for accurate diagnosis.
48
What is one method to reduce miss-interpretation of ultrasound images?
Image from multiple planes. ## Footnote Imaging from different angles can help clarify the presence of true structures.
49
How can using higher frequency transducers help in ultrasound imaging?
It can reduce miss-interpretation of artifacts. ## Footnote Higher frequency transducers provide better resolution, which can help distinguish between artifacts and actual masses.
50
What imaging technique can be used to interrogate suspected artifacts?
Color flow Doppler. ## Footnote Color flow Doppler helps visualize blood flow and can clarify ambiguous findings.
51
What is one way to potentially improve ultrasound image quality related to patient conditions?
Change patient breathing. ## Footnote Patient movement can affect image clarity; adjusting breathing can help stabilize images.
52
What does UEA stand for in the context of ultrasound?
UEAs stand for echo-contrast agents. ## Footnote Echo-contrast agents enhance the visualization of structures in ultrasound imaging.
53
What is the sensitivity of TTE to detect LV thrombus?
75-95% ## Footnote TTE stands for transthoracic echocardiography.
54
What conditions are associated with LV thrombus?
Myocardial infarction and dilated cardiomyopathy ## Footnote These conditions can lead to akinesis of the apex.
55
Can LV thrombus be multiple and mobile?
Yes ## Footnote This characteristic may increase the risk of embolism.
56
How does the texture of LV thrombus compare to myocardium?
Texture usually distinct from myocardium ## Footnote This distinction can aid in diagnosis.
57
What are the risk factors for embolism related to LV thrombus?
Large size, mobility, and protrusion into LV cavity ## Footnote These factors can increase the likelihood of embolic events.
58
What imaging technique is used to follow LV thrombi over time?
TTE (transthoracic echocardiography) ## Footnote TTE is a non-invasive method used for monitoring.
59
What is endocarditis?
Endocarditis is an infection or inflammation of the inner lining of the heart.
60
What attracts micro-organisms in endocarditis?
Micro-organisms are attracted to abnormal valves or areas of turbulent flow.
61
Can endocarditis occur on foreign devices?
Yes, endocarditis can also occur on foreign devices in the heart.
62
What are the two types of endocarditis?
Endocarditis can be infectious or non-infectious.
63
What are common echo findings in endocarditis?
Echo findings can appear thickened, shaggy or pedunculated.
64
Where do vegetations appear in endocarditis?
Vegetations appear on the flow side of valves.
65
What is unique about the motion of vegetations in endocarditis?
The motion of vegetations is independent of valves.
66
What can old (healed) vegetations appear as on an echo?
Old (healed) vegetations can be echogenic in appearance.
67
What is endocarditis usually associated with?
Endocarditis is usually associated with regurgitation.
