To assess the indications and clinical
outcome of minimally invasive coronary artery bypass grafting
with mini-sternotomy and cardiopulmonary bypass (MICS-CABG) for
patients with multiple coronary artery disease, left main trunk
stenosis and/or concomitant heart diseases, we examined results
in 17 patients (mean age 62.5 years) who underwent MICS-CABG.
The average number of distal anastomoses was 2.2 anastomosis/patient.
The category of the coronary lesions was the left main trunk
in 6 patients, triple vessel disease in 7, double vessel disease
in 3, and left anterior descending artery stenosis with aortic
regurgitation in 1 patient. Each operative procedure through
the mini-sternotomy was easily and completely performed in all
patients. By means of postoperative coronary angiography, full
patency without stenosis in all grafts was recognized in 95.0%.
Immediately after the MICS-CABG, all patients showed quick recovery
of respiration, and postoperative admission duration significantly
decreased compared with standard CABG with full sternotomy. The
above results suggest that MICS-CABG is one of the procedures
of choice for patients with multiple coronary artery disease,
left main trunk stenosis and/or concomitant heart diseases.
