    Abstract:
    The Heartstring proximal anastomotic system is a device designed to facilitate the creation of a clampless hand-sewn proximal anastomosis. Thirty-four patients who underwent coronary artery revascularization had 40 proximal anastomoses using the Heartstring device. There were 26 men and 8 women, with the mean age of 70 +/- 8.9 years. Thirty-one patients underwent coronary artery bypass grafting through off-pump procedures and 3 patients on-pump beating procedures. In all patients, saphenous vein grafts were anastomosed to the aorta using the Heartstring device, the median number of distal anastomoses being 2.4 +/- 0.7. Either emergent or urgent surgery was required in 14 patients (41%). Diseased aorta was found in 11 patients (32%). One patient (2.9%) died postoperatively due to ischemic necrosis of the small intestine and the colon. There was no occurrence of postoperative stroke. Of 40 saphenous vein grafts anastomosed with the Heartstring system, 39 (97.5%) were patent. The occluded saphenous vein was not considered to be device related. Our clinical experience demonstrated that the Heartstring system allow us to create clampless and reproductive hand-sewn proximal anastomosis and to decrease the incidence of neurological complication.
