Summary
Subclinical left ventricular systolic dysfunction was detected in children with rheumatic carditis. Tissue Doppler imaging is a valuable tool for monitoring cardiac function in these patients.
Area of Science:
- Pediatric Cardiology
- Cardiovascular Imaging
- Rheumatic Diseases
Background:
- Rheumatic carditis can lead to cardiac dysfunction.
- Early detection of subclinical dysfunction is crucial for management.
Purpose of the Study:
- To assess cardiac function in children with rheumatic carditis using tissue Doppler echocardiography.
- To identify subclinical systolic dysfunction in the left ventricle.
Main Methods:
- Eighty-two children with rheumatic carditis were divided into mild and moderate/severe mitral regurgitation groups.
- A control group of 30 healthy children was included.
- Conventional and tissue Doppler echocardiography were performed at baseline and follow-up.
Main Results:
- Initially, no significant difference in systolic wave velocity was found between mild rheumatic carditis and controls.
- Patients with moderate/severe mitral regurgitation showed prolonged myocardial precontraction and contraction times, and decreased systolic velocity at follow-up.
- Tissue Doppler imaging revealed subclinical left ventricular systolic dysfunction in patients with rheumatic carditis.
Conclusions:
- Subclinical left ventricular systolic dysfunction occurs in children with rheumatic carditis due to ventricular volume overload.
- Tissue Doppler imaging offers a quantifiable method for monitoring cardiac status during follow-up.

01:22Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
01:23Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
01:19Assessing Blood pressure using a doppler ultrasound
To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
01:17Imaging Studies for Cardiovascular System I:Echocardiography
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion, evaluates...

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
