Between May 1997 and November 2002, 68 patients with one or two-vessel disease (55±9 years) underwent Port Access^TM CABG using the Heartport^® endoCPB. The LITA was used in 63 cases, the RITA in 14, a radial artery in 2 and a vein graft in 3. Mean distal anastomoses was 1.3±0.5. Cross clamping, CPB, and operative times were 42±20 min, 64±27 min, and 3.8±1.5 h. Postoperative ventilation was 11±17 h, and ICU stay was 1.9±2.6 days. At day-1, troponin level was 2.3±2.9 UI and blood loss was 398±240 ml. Two patients needed long intubation and two had pleural re-drainage. One patient had a stroke, one had a myocardial infarction, and one underwent revision for bleeding. Hospital stay was 7±3 days. 65% were discharged to home. Follow up was completed in all cases (4.1±1.8 years). CCS score was significantly reduced (from 3.1±0.3 to 1.1±0.3, P<0.0001). Two patients had PTCA and stenting of non-grafted arteries. Five other patients had recurrent angina. Angiograms showed patent grafts in all cases. Two patients died after 19 months and 5 years from non cardiac reasons. In conclusion, Port Access^TM CABG remains a safe technique with stable results at mid-term follow up.
