Minimally invasive cardiac surgery（MICS）has
been developed to offer patients the benefits of open heart operations
with limited skin incision, but this procedure tends to be more
difficult than conventional methods. We tried to evaluate whether
MICS would be reasonable as a standard operation for congenital
heart defects. From August 1997 to March 2000, 42 patients with
atrial septal defects (ASD) and 47 patients with ventricular
septal defects (VSD) underwent total repair by the minimal skin
incision and lower partial median sternotomy. Fifteen ASD patients
and 6 VSD patients were enrolled by residents（resident group).
Twenty-seven ASD patients and 41 VSD patients were treated by
leading surgeons（staff group). We compared the clinical course
of the patients between resident and staff groups. Operative
time, bypass time and cardiac arrest time (VSD) of the staff
group were clearly shorter than those of the resident group (p<0.05).
Other clinical course parameters of the two groups showed no
significant difference. The results of this study indicate that
MICS for ASD and VSD is reasonable as a standard operation because
there was no significant difference of postoperative clinical
course except the time required for the operation.
