[Preliminary clinical experience with the Ventrica automatic distal anastomosis system in coronary surgery].
The surgical treatment of coronary lesions is based on bypassing the anatomical lesions with autologous vascular grafts. This procedure has traditionally been "invasive", requiring a micro-surgery technique, institution of extra-corporeal circulation, as well as temporary cardiac arrest with a cardioplegic solution. Recently, an automatic distal anastomosis procedure has been developed (Ventrica, Medtronic Inc.), based on a magnetic coupling with two implanted intravascular magnets, allowing easy connection between the graft and the coronary artery. The immediately obvious advantages are the time saved, ease of use, reproducibility and reliability. The learning curve is fast. Furthermore, the use of this automatic process does not compromise a manual anastomosis in case of implantation failure. The immediate post-operative results, as well as angiography immediately and at 6 months are all satisfactory. This technique is applicable for multiple revascularisations, all types of autologous grafts, terminal or sequential bypasses, as well as nearly all types of coronaries. The contribution to beating heart, closed thorax coronary surgery seems equally promising.
