In this report, we present our 10-year experience with BIMA and total arterial off-pump coronary artery bypass grafting (OPCAB) and highlight the advantages and disadvantages of the technique.
Results: As compared to the OPCAB group, the patients in CPB group required ion tropic support for a longer duration (29.6 +- 65.1 vs 60.9 +- 71.2, p-value <0.02).
Neurological injury during cardiopulmonary bypass has been attributed to several mechanisms including systemic inflammatory response, hypo-perfusion and micro embolism.11-14 For that particular reason the advent of Off-pump Coronary Artery Bypass (OPCAB) was associated with very high expectations of lowering the incidence of neurological complications.
His conclusions were that total arterial revascularization with BIMA RA graft in OPCAB is safe and effective in DVD and TVD with low mortality.
Abbreviations CABG: Coronary artery bypass grafting CPB: Cardiopulmonary bypass CT: Computed tomography DAA: Distal ascending aorta ET: Endotracheal LVEF: Left ventricular ejection fraction TEE: Transesophageal echocardiography TIA: Transient ischemic attack OPCAB: Off-pump cardiopulmonary bypass PAA: Proximal ascending aorta.
Considering that cardiac operations in patients with previous hematological malignancies are associated with higher rates of complications and mortality (up to 18.7%) [6], we planned OPCAB, expecting this technique to be beneficial.
Followers of this technique believe that minimized ischemia time improves the hemodynamic stability during the OPCAB and eliminates any rush during the bypass surgery [10-12].
Thus, we embarked on this study with a view to identify the contemporary pre-, per-, and postoperative risk factors that discriminate the cases undergoing OPCAB as planned revascularization strategy from those sustaining unplanned intraoperative conversion to ONCAB/BH, in a defined subset of patients with compromised LV function, in our institution.
A relatively small number of studies in our sample (Table 5) compared the HCR procedure using minimally invasive LITA to LAD bypass grafting with conventional CABG or off-pump coronary artery bypass (OPCAB) [7, 12, 27, 28].
Thirty-five patients scheduled for cardiopulmonary bypass (CPB) were identified as the CPB group and 16 patients not scheduled for CPB were identified as the off-pump coronary artery bypass surgery (OPCAB) group.
Some techniques which have gained popularity in India are off-pump coronary artery bypass grafting (OPCAB), use of minimally invasive techniques (MIDCAB) and robotic surgery or totally endoscopic coronary artery bypass surgery (TECAB).
