Summary
A cat-bite led to Streptococcus agalactiae infection of a pulmonary homograft in a patient 19 years post-Ross procedure. Surgical removal of vegetations and homograft replacement successfully treated the unremitting endocarditis.
Area of Science:
- Cardiology
- Infectious Diseases
- Surgical Innovation
Background:
- The patient had a history of a Ross procedure 19 years prior.
- Acute pulmonary homograft endocarditis is a rare but serious complication.
Observation:
- The patient presented with an infection caused by Streptococcus agalactiae, originating from a cat-bite.
- Large vegetations were observed in the pulmonary trunk and right pulmonary artery, indicating severe infection.
Findings:
- Successful surgical intervention involving pulmonary vegetectomy and homograft replacement was performed.
- The patient's unremitting infection was resolved through this procedure.
Implications:
- This case highlights the risk of endocarditis following homograft procedures, even years later.
- It underscores the importance of considering zoonotic infections in specific clinical contexts.
- The successful surgical management demonstrates a viable treatment option for complex homograft endocarditis.

Rheumatic 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...
Endocarditis 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...
