On-pump beating versus arrested heart (conventional) revascularization in severe left ventricular dysfunction

For revascularization of myocardium, the on-pump beating heart technique has been successfully used in patients with either low or high risk. However, the use of this technique in patients with low ejection fraction is not well thoroughly evaluated. The aim of the work was to evaluate the on-pump beating heart technique in subjects with severe left ventricular dysfunction and to compare results with on-pump non-beating (conventional) technique. The present study was held at Al-Azhar University Hospitals, Cairo, Egypt during the period from January 2014 till June 2016. The study included 200 patients who achieved the inclusion criteria. They were allocated either to on-pump beating heart (n = 84) or conventional group (n = 116). Patients were evaluated for in hospital mortality or major postoperative complications. On-pump beating heart was found to be associated with low in hospital mortality, postoperative CK-MB, new myocardial infarction, renal dysfunction and need for hemodialysis. On-pump beating heart technique was better than conventional technique for cardiac revascularization in patients with severe left ventricular dysfunction.
