Key result
Off-pump coronary artery bypass surgery can be safely performed in patients with ischemic cardiomyopathy and diminished left ventricular function, potentially reducing complications associated with cardiopulmonary bypass.
Off-pump CABG is a safe and viable revascularization option for patients with ischemic cardiomyopathy and reduced LV function, potentially reducing complications associated with cardiopulmonary bypass.

May support off-pump CABG in ischemic cardiomyopathy with low LVEF; leaves open need for randomized confirmation.
Patients with ischemic cardiomyopathy and markedly reduced left ventricular (LV) function should be evaluated for coronary artery bypass surgery (CABG) before other surgical options are considered. The success of surgery depends on the presence of viable myocardium and target coronary arteries of acceptable quality. Long-term survival in this setting may be comparable to that with cardiac transplantation. Off-pump CABG can be safely and reproducibly performed in patients with diminished LV function. Off-pump beating heart surgery may provide additional benefits to these patients by reducing some of the complications that are associated with cardiopulmonary bypass.

Khabbaz et al. (2004) conducted a review in Ischemic cardiomyopathy with markedly reduced left ventricular function. Off-pump coronary artery bypass surgery (CABG) vs. On-pump CABG was evaluated. Off-pump coronary artery bypass surgery can be safely performed in patients with ischemic cardiomyopathy and diminished left ventricular function, potentially reducing complications associated with cardiopulmonary bypass.
