Minimally invasive direct coronary artery bypass (MIDCAB) via a mini left thoracotomy incision has been performed for revascularization of the left anterior descending (LAD) artery with the left internal mammary artery (LIMA). In this study, we analyzed the patient’s outcomes in those who underwent MIDCAB.
Between June 2001 and July 2004, a total of 46 patients (37 males and 9 females, mean age of 66.2 +/- 10.9, Euro score of 4.0 +/- 3.0) underwent MIDCAB. Perioperative and follow-up data were entered into a structured database.
LIMA-LAD bypass was performed in all patients and additional bypass to the diagonal artery was performed in 2 patients. No patients were required conversion to sternotomy. The mean intubation period, ICU stay, and postoperative hospital stay were 1.3 +/- 1.8 hours, 1.0 +/- 0.5 days, and 7.5 +/- 3.8 days, respectively. There were no hospital deaths, postoperative heart failure, myocardial infarction, renal failure, prolonged ventilation (>24 hours) or stroke. During the follow-up of 1.0 ± 0.4 years, there were 1 non-cardiac death and 2 cardiac events. These cardiac events were angina related to new coronary lesions which was not seen in the preoperative angiography.
MIDCAB provide early recovery with minimum mortality and morbidity.
