Abstract Objectives: The purpose of this study was to explore the value of the LIMAV measured by ultrasound before CABG in predicting the prognosis of patients after LIMA bypass grafting. Methods: 104 patients who underwent CABG with LIMA as the bridge vessel in the cardiovascular surgery department of our hospital between May 2018 and June 2019 were selected. All patients underwent transthoracic Doppler ultrasonography to measure LIMAV preoperatively. Intraoperatively, MGF and PI of the LIMA bridge were measured using TTFM. The primary endpoint event in this study was cardiac death within 18 months after surgery. Results: The Cox survival analysis showed that the MGF , the LIMAV and LVEF were risk factors for death after CABG . The cut-offs of MGF ,LIMAV and LVEF for the prediction of death after CABG were ≤14 ml/min [AUC: 0.830; Sensitivity:100%; Specificity: 65.6%], ≤60cm/s (AUC: 0.759; Sensitivity:65.5%; Specificity:85.3%) and ≤44%（AUC:0.724; Sensitivity:50%; Specificity: 88.5% ）respectively. Compared with the use of MGF, MGF+LIMAV, combination of the MGF+LIMAV+LVEF （AUC:0.929; Sensitivity:100%; Specificity: 81.1%）resulted in a stronger predictive value（MGF vs MGF+LIMAV+LVEF: p=0.02）. Conclusion: LIMAV measured by transthoracic ultrasound pre-operation combined with intraoperative MGF and LVEF may have a greater value in predicting patients' risk of cardiac death after CABG.

Objective: To evaluate the clinical safety of left internal mammary artery (LIMA) harvesting in hemodynamically unstable patients after establishing cardiopulmonary bypass (CPB) in isolated coronary artery bypass graft (CABG) surgery. Methods: The prospective observational study was conducted at Chaudhry Pervaiz Elahi Institute of Cardiology, Multan, Pakistan, from December 2016 to August 2018. All patients undergoing isolated CABG surgery in which LIMA conduit was harvested after establishing cardiopulmonary bypass because of hemodynamic instability at induction of anaesthesia or during surgery were included in the study. Preoperative, operative and postoperative characteristics of the patients were recorded. Data was analyzed using SPSS 19. Results: In Forty nine patients including 39 male and 10 female, early CPB had to be established because of hemodynamic instability and afterwards LIMA was harvested. Out of 49, 30 patients presented with CCS class III angina. 37 (75.5%) patients were scheduled on elective coronary surgery waiting list. There were 39 (79.59%) patients who weaned off bypass on mild inotropic support and 4 (8.16%) patients needed IABP support. All patients had multi-vessel coronary artery disease. Mean number of grafts were 3.428±0.577, CPB time was 110.59±25.594 and hospital stay was 5.367±1.424. Conclusions: The study showed that LIMA can be safely harvested in unstable patients after establishing extracorporeal circulation and by using this operative strategy in patients who need urgent or emergent surgical coronary revascularization LIMA can be safely used as a conduit. doi: https://doi.org/10.12669/pjms.35.3.988 How to cite this:Sher-i-Murtaza M, Baig MAR.

We present the case of a 72-year-old man who underwent off-pump coronary artery bypass grafting of 4 coronary arteries with exclusive use of the left internal mammary artery with a side-branch (mediastinal artery). Before discharge from the hospital, contrast computed tomography angiography confirmed the patency of all 4 coronary grafts. Use of the mediastinal artery side-branch of the internal mammary artery allowed grafting of 4 coronary arteries using only one internal thoracic artery.
