Introduction. This study was performed to evaluate mid-term results and postoperative quality of life after minimally invasive direct coronary artery bypass graft (MIDCABG).

Methods. From March 1995 to December 1998, 100 patients underwent MIDCABG at our hospital; their mean age was 62 ± 6.7 years, 31 (31%) had unstable angina, and 19 (19%) were female patients. All patients were followed up both by direct visit and with questionnaires.

Results. No perioperative deaths occurred; perioperative myocardial infarction rate was 2/100 (2.0%). Average follow-up was 32 ± 7.8 months, with an actuarial survival of 100%, and redo-free survival of 99.0% ± 1.0%, an myocardial infarction-free survival of 98.0% ± 1.4%, and an angina-free survival of 92.6% ± 4.1% at 3 years. Both the Physical Activity Score and the Psychological General Well-being Index improved after surgery, with a percentage improvement of 28% and 21% at 12 months postoperatively, respectively. Significant improvements were found in anxiety, positive well-being, vitality, and general health domains of PGWBI.

Conclusions. MIDCABG can be, in selected patients, a reliable and safe option. Patients who undergo that procedure are free of major complications and enjoy a good quality of life after surgery.
