A 61-year-old woman was admitted
to our hospital because of acute heart failure. The angiogram
showed an enlarged aortic root and aortic incompetence which
indicated annulo-aortic ectasia. An aortic valve-sparing operation
was impossible because of severe prolapse of the aortic valve
and the patient hesitated to have anti-coagulation therapy. Thus
we performed aortic root replacement with the FreestyleTM stentless
porcine valve (Medtronic Inc.). We plicated each original commissure
in order to narrow the enlarged annulus and attach the Freestyle
valve to the annulus directly by continuous suture. There was
no significant difference in surgical technique and aortic cross-clamping
time, compared to conventional operation. Aortic root replacement
with the Freestyle valve seems an attractive option especially
for elderly patients or cases in which of contraindicated for
anti-coagulation therapy.
