Overview
Early valve surgery should be scheduled when there is heart failure due to the valve dysfunction, left-sided infective endocarditis due to Staphylococcus aureus, fungal or highly resistant organisms, or a heart block, annular or aortic abscess or destructive lesions. Other indications include persistent bacteremia or fever 5 to 7 following the initiation of the antibiotics, relapse of the infection depsite a complete course of antibiotics in prosthetic valve endocarditis when no portal of infection can be identified, recurrent emboli and persistent vegetations despite antibiotic therapy, and mobile vegetations with a length more than 10 mm in native valve endocarditis. Surgical removal of the valve is necessary in patients who fail to clear micro-organisms from their blood in response to antibiotic therapy, or in patients who develop cardiac failure resulting from destruction of a valve by infection. A removed valve is usually replaced with an artificial valve which may either be mechanical (metallic) or obtained from an animal such as a pig; the latter are termed bioprosthetic valves.[1] Surgical treatment of endocarditis involves excision of all infected valve tissue, drainage and debridement of abscess cavities, repair or replacement of damaged valves, and repair of any associated pathology such as fistulas or septal defects.[1]
Indications
Indications for surgical debridement of vegetations and infected perivalvular tissue, with valve replacement or repair as needed are listed below:[1]
- Moderate to severe congestive heart failure due to valve dysfunction
- Unstable valve prosthesis
- Uncontrolled infection for > 1–3 week despite maximal antimicrobial therapy
- Persistent bacteremia
- Fungal endocarditis
- Relapse after optimal therapy in a prosthetic valve
- Vegetation in Situ
- Prosthetic valve endocarditis with perivalvular invasion
- Endocarditis caused by Pseudomonas aeruginosa or other gram-negative bacilli that has not responded after 7–10 days of maximal antimicrobial therapy
- Perivalvular extension of infection and abscess formation
- Staphylococcal infection of prosthesis
- Persistent fever (culture negative)
- Large vegetation (>10 mm is associated with an increased risk of embolism)
- Relapse after optimal therapy in a native valve
- Vegetations that obstruct the valve orifice
- Onset of AV block

Principles of Surgical Treatment of Endocarditis
Surgical treatment of endocarditis includes:[1]
- Excision of all infected valve tissue
- Drainage and debridement of abscess cavities
- Repair or replacement of damaged valves
- Repair of any associated pathology such as septal defect, fistulas
Aortic Valve - Surgical Options
If the infection is limited to the leaflets, then the aortic valve should be replaced. If the infection extends to the anulus or beyond, then the infected tissues should be debrided. Any abscesses should be drained and the aortic root should be replaced.
Atrioventricular Valve - Surgical Options
If the infection is limited to the leaflets, then the vegetations should be excised, perforations should be repaired, and a reduction annuloplasty should be performed. If the infection extends to the anulus or beyond, then a valve replacement should be performed, and abscesses should be debrided and obliterated. In some cases the tricuspid valve may be excised.
Surgical Outcomes
Operative mortality is 15 - 20%. The development of an infection of a prosthetic valve during operation for native valve endocarditis is 4%, it is higher (12 - 16%) if active endocarditis is present at the time of the surgery. Late survival at 5 years for native valve endocarditis is 70 - 80% and for prosthetic valve endocarditis is 50 - 80%.[1]
2008 and Incorporated 2006 ACC/AHA Guidelines for the Management of Patients with Valvular Heart Disease (DO NOT EDIT) [3]
Intraoperative Assessment (DO NOT EDIT) [3]
| Class I |
| "1. Intraoperative transesophageal echocardiography is recommended for valve surgery for infective endocarditis. (Level of Evidence: B)" |
