Cirugía de revascularización coronaria sin pinzamiento aórtico, ventajas y resultados

the coronary revascularization surgery has been the best option to treatment of ischemic heart disease. however, as a result of the advent of hemodynamic procedures, the complexity of the patients subject to surgery, increase importantly. for this cause the surgeons has modified their techniques and has arisen the off-pump coronary revascularization surgery. this technique cause a low inflammatory response and accordingly low organic damage to avoid the extracorporeal circulation and the "pump exit"; nevertheless in many cases are incomplete, more complex, uncomfortable and not practicable in all patients. for this reason has appeared a procedure to allow a join between the advantages of without aortic cross-clamping and the security of the circulatory assistance to patient: the coronary revascularization surgery without cross-clamping with circulatory assistance and heart-beating. to determine the results of the coronary revascularization surgery without aortic cross-clamping with circulatory assistance and heart-beating we studied 64 patients with ischemic heart disease of march of 2002 to may of 2005. in comparison with conventional surgery, the bleeding, mediastinitis, perioperative infarct to heart and cerebrovascular accident was not significant (p = 0.12-0.34) however the mortality was more low (p < 0.05) in this group (7.40%) in comparison with conventional surgery (8.79%).
