Two-dimensional echocardiographic recognition of aortic valve ring abscess
European Heart Journal
|October 1, 1984
Summary
Two-dimensional echocardiography (2D-echo) aids in diagnosing perivalvular aortic abscesses in patients with suspected aortic endocarditis. While helpful, 2D-echo may underestimate the extent of these serious infections.
Area of Science:
- Cardiology
- Infectious Diseases
- Medical Imaging
Background:
- Perivalvular aortic abscesses are serious complications of infective endocarditis.
- Accurate diagnosis is crucial for effective surgical management.
Purpose of the Study:
- To evaluate the diagnostic utility of 2D-echocardiography in identifying perivalvular aortic abscesses.
Main Methods:
- 2D-echocardiography was performed on 42 patients with suspected aortic endocarditis prior to surgery.
- Surgical findings were used as the gold standard for comparison.
Main Results:
- Perivalvular abscesses were confirmed in 12 patients at surgery.
- 2D-echo detected abscesses in 8 of these patients, visualizing echo-free cavities.
- Four abscesses were missed by 2D-echo, particularly those around mechanical prostheses.
- 2D-echo findings sometimes underestimated the size and location of abscesses.
Conclusions:
- 2D-echocardiography is a valuable tool for diagnosing perivalvular aortic infections.
- Limitations exist, especially with complex cases or prosthetic material, potentially underestimating lesion severity.

866
Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

01:23Mitral Stenosis II: Clinical features and Diagnostic Tests
565
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

01:15Aortic Regurgitation I: Introduction
1.7K
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

1.2K
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

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...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
