Fatal outcome of aortic-valve endocarditis in noncompaction/hypertrabeculation
International Journal of Cardiology
|September 8, 2009
Summary
A 56-year-old man with Staphylococcus aureus bacteremia developed severe heart failure. Echocardiography revealed aortic valve vegetation and left ventricular noncompaction, leading to rapid mortality.
Area of Science:
- Cardiology
- Infectious Diseases
- Pathology
Background:
- Heart failure is a complex clinical syndrome.
- Staphylococcus aureus bacteremia can lead to severe complications.
- Left ventricular noncompaction is a rare congenital cardiomyopathy.
Observation:
- A 56-year-old male presented with symptoms of heart failure.
- Blood cultures identified Staphylococcus aureus.
- Echocardiography showed an 18 mm aortic valve vegetation and left ventricular noncompaction.
Findings:
- The patient experienced intractable heart failure and died within 24 hours.
- Autopsy confirmed aortic valve endocarditis, severe left ventricular hypertrophy, fibrosis, and noncompaction.
Implications:
- This case highlights the aggressive nature of Staphylococcus aureus endocarditis.
- Left ventricular noncompaction may predispose to severe infectious complications.
- Rapid diagnosis and treatment are crucial for patients with suspected endocarditis and underlying cardiac abnormalities.

01:25Endocarditis I: Introduction
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
01:15Aortic Regurgitation I: Introduction
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...
01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
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...
01:18Endocarditis III: Medical Management
Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...
01:25Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
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...
