	<span style=\"font-family:Verdana;\">Objectives: Due to recent spread of minimally
invasive surgery, the demand for minimally invasive cardiac surgery (MICS) is
increasing. We investigate the usefulness of minimally invasive aortic valve
replacement (MICS-AVR) which was performed in our hospital. Methods:</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">Of 63 consecutive patients
undergone an isolated aortic valve replacement</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">(AVR), 16 patients underwent MICS-AVR with partial lower
sternotomy (M group) and 47 patients underwent AVR with median full sternotomy
(C group).</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">We
compared the two groups in a retrospective study. Results: No significant
difference was found in the surgical and perioperative-related factors between
the two groups. However, the average of aortic cross-clamping time was longer,
and intensive and high care unit stay was shorter in the M group. A tendency to
decrease blood transfusion was observed in the M group. There was no hospital
death in all patients. The mean follow-up period was 29 ¡À 15 months. There was
no significant difference between the two groups in the survival rate, and the
5</span><span style=\"font-family:Verdana;\">-</span><span style=\"font-family:Verdana;\">year
survival rates were 88.9% in the M group and 85.9% in the C group.</span><span style=\"font-family:Verdana;\"> Conclusion: It was suggested that the
MICS-AVR could be safe and useful procedure in AVR.</span>
