Insights
This case study describes cardiac rhabdomyomas in an infant presenting with right ventricular tachycardia and symptoms mimicking infective endocarditis. Tuberous sclerosis features appeared later, highlighting a rare association.
Area of Science:
- Pediatric Cardiology
- Cardiovascular Pathology
- Medical Genetics
Background:
- Cardiac rhabdomyomas are rare benign tumors, often associated with tuberous sclerosis complex.
- Tuberous sclerosis complex (TSC) is a genetic disorder affecting multiple organs.
- Infective endocarditis is a serious infection of the heart valves or endocardium.
Observation:
- An infant presented with right ventricular tachycardia and clinical signs suggestive of infective endocarditis.
- Cardiac rhabdomyomas were identified as the cause of the infant's symptoms.
- Subsequent development of characteristic features of tuberous sclerosis was noted.
Findings:
- This is the first reported case of cardiac rhabdomyoma presenting with clinical features mimicking infective endocarditis.
- The infant's presentation highlights the diverse initial clinical manifestations of tuberous sclerosis complex.
- The co-occurrence of cardiac rhabdomyoma and symptoms of infective endocarditis is a novel observation.
Implications:
- This case expands the differential diagnosis for infants presenting with tachycardia and endocarditis-like symptoms.
- Early recognition of cardiac rhabdomyomas, even with atypical presentations, is crucial for timely management of tuberous sclerosis complex.
- Further research may elucidate potential links or shared pathways between cardiac tumor development and inflammatory/infectious processes.
Abstract:
We report a case of cardiac rhabdomyomas in an infant who presented with right ventricular tachycardia, and a clinical picture of infective endocarditis. Typical features of tuberous sclerosis developed subsequently. To the best of our knowledge, cardiac rhabdomyoma has not been reported previously in association with infective endocarditis.

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...

929
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...

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

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...

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...

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...
