Abstract:
Infective endocarditis (IE) carries high morbidity and mortality. Although minimal in incidence, fungal causes (mostly Candida species) carry the highest mortality among all cases of infective endocarditis. We describe a rare case of a 47-year-old male with a past medical history of cerebral vascular accident (CVA), heart failure with reduced ejection fraction status post (SP) automated implantable cardioverter defibrillator (AICD) placement, paroxysmal atrial fibrillation, coronary artery disease (CAD), infective endocarditis with mitral valve replacement and tricuspid valve replacement, and pulmonary hypertension who presented to the emergency department (ED) with complaints of shortness of breath and weakness for four days. The patient was admitted to the cardiac care unit (CCU) due to persistent hypotension despite being on a continuous milrinone drip at home. The patient was initially started on antimicrobial agents for sepsis most likely secondary to pneumonia. Echocardiographic imaging showed a large vegetation on the tricuspid valve; hence, blood cultures were sent and came back positive for Candida sp. Appropriate antifungals (micafungin) were added to the medication regimen, and the patient was transferred to a tertiary hospital for surgical intervention. Patients with bioprosthetic valve replacement require regular follow-ups as this would allow providers to catch symptoms of developing endocarditis and prevent disease progression. These appointments may also decrease other risk factors for the disease, including but not limited to infected lines.
Insights
Fungal infective endocarditis, though rare, has the highest mortality. This case highlights a Candida species infection in a patient with multiple cardiac conditions, emphasizing the need for vigilant follow-up after valve replacement.
Area of Science:
- Cardiology
- Infectious Diseases
- Mycology
Background:
- Infective endocarditis (IE) presents significant morbidity and mortality.
- Fungal IE, primarily caused by Candida species, exhibits the highest mortality rate among all IE cases.
- Patients with prosthetic valves, especially bioprosthetic, are at increased risk.
Observation:
- A 47-year-old male with a complex cardiac history (heart failure, prior valve replacement, AICD) presented with severe symptoms.
- Initial presentation mimicked sepsis secondary to pneumonia, but echocardiography revealed a large tricuspid valve vegetation.
- Blood cultures confirmed Candida species fungemia.
Findings:
- The patient received micafungin and was transferred for surgical intervention.
- Successful management of fungal IE requires prompt diagnosis and targeted antifungal therapy.
- This case underscores the challenges in diagnosing and managing fungal IE in patients with complex medical histories and prosthetic material.
Implications:
- Regular follow-up for patients with bioprosthetic valve replacement is crucial for early detection and prevention of endocarditis progression.
- Proactive monitoring can mitigate risks associated with prosthetic material and potential sources of infection.
- This case emphasizes the critical role of echocardiography and blood cultures in diagnosing rare but life-threatening fungal IE.
