Surgical erapy
Decisions about timing of surgical intervention should be
made by a multispecialty Heart Valve Team of cardiolog y,
cardiothoracic surgery, and infectious disease specialists.
I B
Early surgery
a
is indicated in patients with IE who present
with valve dysfunction resulting in symptoms of HF.
I B
Early surgery
a
is indicated in patients with le-sided IE caused
by S. aureus, fungal, or other highly resistant organisms.
I B
Early surgery
a
is indicated in patients with IE complicated
by heart block, annular or aortic abscess, or destructive
penetrating lesions.
I B
Early surgery
a
for IE is indicated in patients with evidence of
persistent infection as manifested by persistent bacteremia or
fevers lasting longer than 5-7 days aer onset of appropriate
antimicrobial therapy.
I B
Surgery is recommended for patients with PVE and relapsing
infection (defined as recurrence of bacteremia aer a complete
course of appropriate antibiotics and subsequently negative blood
cultures) without other identifiable source for portal of infection.
I C
Complete removal of pacemaker or defibrillator systems,
including all leads and the generator, is indicated as part of the
early management plan in patients with IE with documented
infection of the device or leads.
I B
Complete removal of pacemaker or defibrillator systems,
including all leads and the generator, is reasonable in patients
with valvular IE caused by S. aureus or fungi, even without
evidence of device or lead infection.
IIa B
Complete removal of pacemaker or defibrillator systems,
including all leads and the generator, is reasonable in patients
undergoing valve surgery for valvular IE.
IIa C
Early surgery
a
is reasonable in patients with IE who present
with recurrent emboli and persistent vegetations despite
appropriate antibiotic therapy.
IIa B
Early surgery
a
may be considered in patients with NVE
who exhibit mobile vegetations >10 mm in length (with or
without clinical evidence of embolic phenomena).
IIb B
a
Early surgery is defined as during initial hospitalization before completion of a full therapeutic
course of antibiotics.
