Nowadays, applications of the operations on beating heart has gained importance due to the advances in technical level and recently it is commonly used with the developed minimally invasive techniques. Robotic-assisted coronary artery bypass grafting (CABG) is a, minimal invasive surgical technique which is performed successfully since 2004 in our clinic. The purpose of this study was to evaluate mid-term clinical results and graft patency by cardiac catheterization and multislice tomographic angiography.
Between April 2004 and November 2012, 260 patients underwent robotic assisted coronary artery bypass grafting on beating heart. Sixty patients underwent invasive coronary angiography and multislice computed tomographic angiography for assessment of graft patency.
Follow-up time of sixty patients was a mean period of 48,29±19,87 months (range,12-83 months), average operative time and left internal mammary artery harvest time was 163,87±22,5 and 40,65±5,9 (30-55) minutes. Length of stay at the intensive care unit was 14.4±2,61 hours. Percentage of the patients who received blood products perioperatively was found to be 16%. Length of hospital stay was 5,54±1,71 (range,4-10 days). There were no operative mortality, stroke or early reintervention. Postoperative graft patency rate was 94%. Freedom from target vessel reintervention was 98%.
Robotic-assisted CABG was accomplished with low morbidity, mortality and reintervention rates. It is a safe procedure in selected patients and produces excellent midterm graft patency that is comparable with published data. Our results which showed similarities with contemporary literature lead us to the idea of future importance and common usage of minimally invasive interventions.
