Infective Endocarditis
Are you or a loved one experiencing prolonged fever, a new heart murmur or signs of embolism? Infective endocarditis in Tunisia is a serious infection of the heart valves that requires rapid management by a multidisciplinary team (cardiologists, infectious disease specialists, cardiac surgeons). With attractive prices starting from €1500, benefit from accurate diagnosis (echocardiography) and appropriate treatment (antibiotic therapy, surgery).
What is infective endocarditis?
Infective endocarditis (IE) is a serious infection of the endocardium (the inner lining of the heart) and the heart valves. It is most often bacterial in origin, more rarely fungal. Vegetations (clumps of fibrin, platelets and microorganisms) form on the valves, leading to valve destruction (heart failure), septic emboli and severe sepsis.
- Medico-surgical emergency
- Mortality 20-30%
- Antibiotic therapy 4 to 6 weeks
- Cardiac surgery in 30-50% of cases
What are the signs of infective endocarditis?
General signs
General signs of infective endocarditis include prolonged fever above 38-39 °C. Chills and night sweats are common. Asthenia, anorexia and weight loss may occur. Finally, muscle pain and arthralgia are also observed.
Cardiac signs
Cardiac signs of infective endocarditis include a new or changed heart murmur. Heart failure may manifest as dyspnea and edema. Rhythm disorders, such as atrial fibrillation or atrioventricular block, are also possible.
Peripheral signs
Infective endocarditis manifests with skin signs such as petechiae or purpura. Osler's nodes, which are painful pulps, may appear. Janeway lesions are observed on the palms and soles. Finally, visceral emboli can affect the brain, spleen or kidneys.
How is diagnosis made in Tunisia?
Biological and microbiological workup
The biological workup for infective endocarditis includes blood cultures, with 3 pairs from 3 different sites, performed before any antibiotic therapy. 16S PCR may be performed on the operated valve in case of negative blood cultures. Serologies are performed to test for Coxiella, Bartonella or Legionella. Inflammatory syndrome is assessed by CRP and hyperleukocytosis.
Echocardiography (major criteria)
Echocardiography is essential for the diagnosis of endocarditis. Transthoracic echocardiography is the first examination, with a sensitivity of 50 to 70%. Transesophageal echocardiography is the reference examination, with a sensitivity above 90-95%. It allows visualization of vegetations, abscesses and valvular regurgitation.
Duke criteria (modified 2023)
The diagnosis of infective endocarditis is based on the Duke criteria. It is confirmed by the presence of 2 major criteria, combining positive blood cultures and echocardiography. It can also be established by 1 major criterion associated with 3 minor criteria, or by 5 isolated minor criteria.
How is management carried out?
1. Antibiotic therapy
Antibiotic therapy for infective endocarditis is initially probabilistic, with amoxicillin and gentamicin for native valve, or vancomycin and gentamicin for prosthesis. It is then directed according to the antibiogram, for a total duration of 4 to 6 weeks. Monitoring is provided by antibiotic dosage, CBC and creatinine levels.
2. Valve surgery
Surgery for infective endocarditis is indicated urgently in cases of severe heart failure, recurrent emboli or abscesses. It is indicated non-urgently for severe valve insufficiency or antibiotic therapy failure. Interventions include valve replacement with mechanical or biological prosthesis, or valve repair.
3. Intensive care management
Management of complications is based on specific treatments. Septic shock is treated by fluid resuscitation and norepinephrine. Heart failure is managed with diuretics, dobutamine or ECMO. Renal failure requires continuous hemofiltration (CVVHDF). ARDS is managed by protective mechanical ventilation and prone positioning.
What are the risks and complications?
Several complications can occur during infective endocarditis. Heart failure is observed in 30 to 50% of cases. Septic emboli can affect the brain in 20 to 40% of cases, as well as the spleen or kidneys. Annular or septal abscesses may form. Mycotic aneurysm carries a risk of rupture. Glomerulonephritis can lead to acute renal failure. Finally, septic shock can progress to multiple organ failure.

Frequently asked questions about infective endocarditis
1Is infective endocarditis always bacterial in origin?
In 90 to 95% of cases, infective endocarditis is bacterial in origin. The most common pathogens are streptococci (S. viridans, S. bovis), staphylococci (S. aureus) and enterococci. In 5 to 10% of cases, it may be fungal (Candida, Aspergillus) or culture-negative (Bartonella, Coxiella).
2Can infective endocarditis be prevented?
Yes, prevention is based on rigorous oral hygiene, treatment of dental infectious foci, antibiotic prophylaxis before certain at-risk dental procedures (in valve prosthesis carriers or those with a history of endocarditis), and avoidance of intravenous drugs.
3Is transesophageal echocardiography (TEE) systematic?
TEE is recommended in all cases of suspected or confirmed infective endocarditis. It is more sensitive than transthoracic echocardiography (TTE) for visualizing vegetations, abscesses and complications. TEE is performed within the day in Tunisia.
4Is valve surgery always necessary in case of endocarditis?
No, surgery is not systematic. It is indicated in 30 to 50% of cases, in the presence of severe heart failure, recurrent emboli, abscesses or antibiotic therapy failure. In uncomplicated forms, antibiotic therapy alone may be curative.
5What is the duration of antibiotic treatment for infective endocarditis?
Antibiotic therapy generally lasts 4 to 6 weeks for native valve endocarditis, and 6 to 8 weeks for prosthetic valve endocarditis. Treatment is administered intravenously, in hospital or on an outpatient basis with regular monitoring.
6Can infective endocarditis recur after treatment?
The risk of recurrence is 2 to 5% within 5 years of the initial episode. It is higher in cases of intravenous drug use, valve prosthesis, or persistence of an infectious focus. Prophylaxis and regular cardiological follow-up are essential.
7Are dental procedures prohibited after infective endocarditis?
No, dental procedures are not prohibited, but they must be performed under antibiotic prophylaxis in at-risk patients (valve prosthesis, history of endocarditis). Rigorous oral hygiene is recommended to prevent recurrence.
