Question
What are the common etiologies of valvular disorders?
Answer
Rheumatism, infectious endocarditis, ischemic heart disease, and valvular degeneration.
2
Question
What is stenosis in the context of valvular disorders?
Answer
Stenosis is the impaired opening of a valve.
3
Question
What is insufficiency in the context of valvular disorders?
Answer
Insufficiency is the impaired closure of a valve, allowing hemodynamically important back blood flow.
4
Question
What are the potential complications associated with bacterial endocarditis?
Answer
Complications include arrhythmia, atrial fibrillation, thromboembolism.
5
Question
What is arrhythmia?
Answer
Arrhythmia is irregular atrial activity characterized by irregular waves.
6
Question
What sounds are auscultated in mitral stenosis?
Answer
A loud S1 and a diastolic rumble are observed.
7
Question
What are the auscultation positions for valve sounds?
Answer
Intercostal spaces 1, 2, 3, 4, and 5 for Aortic, Tricuspid, Mitral, and Pulmonary valves.
8
Question
What is the significance of the phonocardiogram in diagnosing mitral stenosis?
Answer
It helps visualize the specific heart sounds and timing.
9
Question
What diagnostics are used for mitral stenosis?
Answer
Auscultation, phonocardiography, ECG, chest X-ray, and echocardiography.
10
Question
What is prominent in the echocardiography of mitral stenosis?
Answer
Left ventricular enlargement and pulmonary congestion.
11
Question
What symptoms are associated with mitral stenosis?
Answer
Fatigue, poor tolerance of exercise, palpitations, cough, left-sided heart failure, orthopnea.
12
Question
What is a characteristic sign of left-sided heart failure in mitral stenosis?
Answer
Palpitation in atrial fibrillation.
13
Question
What findings can be seen on a chest X-ray in mitral stenosis?
Answer
Left atrial enlargement, prominent pulmonary vessels.
14
Question
What is the etiology of mitral valve prolapse?
Answer
It may be due to rheumatic fever, infectious endocarditis, or ischemic disease.
15
Question
What are the complications of mitral valve insufficiency?
Answer
Atrial fibrillation, heart failure, pulmonary edema.
16
Question
What therapy is indicated for mitral valve insufficiency?
Answer
Balloon valvuloplasty or surgical replacement of the mitral valve.
17
Question
What causes aortic stenosis?
Answer
It causes a systolic pressure gradient between the left ventricle and the aorta.
18
Question
What symptoms are associated with aortic stenosis?
Answer
Syncope, dizziness, and exercise intolerance.
19
Question
What are the classic findings in the left ventricle due to aortic stenosis?
Answer
Left ventricular hypertrophy, left atrial hypertrophy, and pulmonary congestion.
20
Question
What is a common auscultation finding in mitral insufficiency?
Answer
A third filling sound, diastolic rumble, or systolic whir.
21
Question
What diagnostic testing confirms aortic stenosis?
Answer
Phonocardiography, ECG, chest X-ray, and echocardiography.
22
Question
What are the possible causes of left ventricular dilation in mitral insufficiency?
Answer
Volume overload due to regurgitation heralds left ventricular dilation.
23
Question
What is the usual treatment for aortic stenosis?
Answer
Surgical replacement of the affected valve.
24
Question
What is significant about a third filling sound in aortic stenosis?
Answer
It indicates poor left ventricular function.
25
Question
What stage of dilation is erosive in mitral insufficiency diagnostics?
Answer
Left atrial enlargement and pulmonary congestion.
26
Question
Describe the treatment options for mitral stenosis.
Answer
Balloon valvuloplasty and surgical replacement.
27
Question
What is atrial fibrillation and how is it related to valvular disease?
Answer
Atrial fibrillation is an arrhythmia that can be a complication of mitral stenosis, leading to increased risk of thromboembolism.
28
Question
What conditions can cause infective endocarditis as a complication?
Answer
Recurrent bronchitis and events related to valvular rupture.
29
Question
What is the role of echocardiography in valvular diseases?
Answer
It allows visualization of heart structure and function, identifying abnormalities like hypertrophy or dilation.
30
Question
What should be monitored in patients with mitral or aortic stenosis?
Answer
Symptoms of heart failure and arrhythmias such as atrial fibrillation.
