|A Case of Redo Operation for
Prosthetic Valve Endocarditis with Acute Myocardial Infarction
after Aortic Valve Replacement Using a Freestyle Stentless Valve
(Department of Cardiovascular Surgery, Osaka National
Hospital, Osaka, Japanj
|A 68-year-old woman received aortic
valve replacement (AVR) with a Freestyle stentless valve using
a subcoronary technique for aortic stenosis and regurgitation
in September 2000. She complained of chest pain, had low grade
fever and findings of inflammation and was admitted to our hospital
with a diagnosis of acute myocardial infarction in December 2000.
She suffered from repetitive or recurrent myocardial infarction.
Transesophageal echocardiogram revealed no abnormal findings
of the Freestyle stentless valve, but her blood culture was positive
for methicillin-resistant coagulase negative Staphylococcus
aureus (MRCNS) and she underwent an emergency operation.
The Freestyle stentless valve was removed and replaced with a
mechanical valve. The patient's intraoperative tissue grew MRCNS
and parenteral antibiotics were administered for 8 weeks after
surgery. Her condition was complicated with multiple cerebral
infarction, however she was discharged on the 113th postoperative
day and is doing well without recurrence of infection 12 months
after the operation.
