Endocarditis

Long-term cardiac follow-up after valve infection, with imaging and prevention guidance.

Endocarditis is an infection of the heart valves or the endocardium, the inner lining of the heart. It is uncommon but serious, typically requiring weeks of intravenous antibiotics and sometimes valve surgery to eradicate. Patients who develop endocarditis often have predisposing factors — prior valve disease, prosthetic valves, intracardiac devices, or specific health conditions — and once treated they need lifelong cardiac follow-up to monitor valve function and prevent recurrence. The acute phase of endocarditis is managed in the hospital, often by infectious disease and cardiology together. Dr. Kedan provides the long-term cardiology care after discharge: monitoring the valves, watching for late complications, and counseling on prevention.

What Cardiolucent Evaluates

  • Complete hospital records review including organism, antibiotics, and any complications
  • Echocardiography to assess residual valve damage and function
  • POCUS at every visit for interval reassessment
  • EKG and rhythm screening for conduction abnormalities that can result from valve infection
  • Recovery monitoring through and beyond the antibiotic course
  • Coordination with cardiac surgery at Cedars-Sinai when intervention is needed
  • Long-term prevention plan including dental care, antibiotic prophylaxis when indicated, and risk-factor modification

Common Symptoms

  • Persistent fevers, chills, and night sweats
  • Unexplained fatigue and weight loss
  • New or changing heart murmur
  • Shortness of breath or signs of heart failure
  • Embolic events such as stroke, splinter hemorrhages, or peripheral skin lesions
  • Symptoms can be insidious, especially with less aggressive organisms

Risk Factors

  • Prosthetic heart valves
  • Congenital heart disease, particularly unrepaired or recently repaired
  • Prior endocarditis
  • Intracardiac devices including pacemakers and defibrillators
  • Chronic intravenous catheter use or hemodialysis
  • Injection drug use
  • Poor dental health
  • Certain valve abnormalities such as bicuspid aortic valve or severe mitral valve disease

How Cardiolucent Approaches Treatment

Acute endocarditis is treated in the hospital with prolonged intravenous antibiotics, typically four to six weeks, guided by the organism and culture results. Surgery is required in a meaningful proportion of cases — for heart failure, persistent infection, large vegetations with embolic risk, or specific organisms. After discharge, Dr. Kedan focuses on long-term cardiac follow-up: serial echocardiography to track valve function, screening for late complications, and a clear prevention plan that includes meticulous dental care and antibiotic prophylaxis before high-risk procedures when indicated.

Common Questions

Frequently Asked Questions

What is endocarditis?
Endocarditis is infection of the heart valves or inner lining of the heart, most often caused by bacteria entering the bloodstream and attaching to a damaged or prosthetic valve. It can rapidly damage the valve, embolize to other organs, and become life-threatening if not treated promptly.
How is endocarditis diagnosed?
Diagnosis combines clinical findings, blood cultures identifying the responsible organism, and echocardiography showing vegetations or new valve damage. Transesophageal echocardiography (TEE) is often needed because it visualizes the valves with much higher resolution than transthoracic echo.
How is endocarditis treated?
Treatment requires several weeks of intravenous antibiotics chosen for the specific organism, with careful monitoring of response. A significant proportion of patients ultimately require valve surgery, particularly for heart failure, persistent infection, large vegetations, or specific organisms like Staphylococcus aureus.
Will I always need antibiotics before dental work?
Antibiotic prophylaxis before dental procedures is recommended for specific high-risk patients — those with prosthetic valves, prior endocarditis, certain congenital heart conditions, or post-transplant valvulopathy. Many patients with valve disease do not require routine prophylaxis under current guidelines. Dr. Kedan reviews your individual indication with you.
Can endocarditis happen again?
Yes — prior endocarditis is itself a risk factor for recurrence. This is why long-term follow-up, meticulous dental care, and antibiotic prophylaxis when indicated are so important.
Why does dental care matter so much?
The mouth is one of the most common sources of bacteria that can cause endocarditis, particularly streptococcal species. Regular dental care, prompt treatment of dental infections, and good oral hygiene meaningfully reduce the risk of valve infection.
What kind of follow-up do I need after endocarditis?
Patients typically have echocardiography at intervals after completing antibiotics to monitor valve function and confirm there is no recurrence, with closer follow-up if valve damage was significant. Dr. Kedan tailors the frequency to your specific situation.
Should my family be worried?
Endocarditis itself is not contagious in the usual sense. However, family members with known valve disease or prosthetic valves should ensure their own prevention strategies are in place, including good dental care and antibiotic prophylaxis when indicated.
What lifestyle factors matter?
Excellent oral hygiene, prompt treatment of skin infections, avoidance of injection drug use, and careful management of intravenous catheters or dialysis access are the main modifiable factors. General cardiovascular risk-factor management also supports overall heart health.
