Randomized Controlled TrialRetransfusion of cardiotomy suction blood impairs haemostasis: ex vivo and in vivo studies.
Cardiotomy suction blood in volumes corresponding to 10-20% of the systemic blood volume is retransfused during cardiopulmonary bypass. We hypothesized that retransfusion of unwashed cardiotomy suction blood influences coagulation and platelet function. ⋯ The ex vivo results suggest that addition of unwashed cardiotomy suction blood in clinically relevant volumes impairs systemic haemostasis. Retransfusion of smaller volumes in vivo has no or limited impact. Avoiding retransfusion of larger amounts of unwashed cardiotomy suction may improve postoperative haemostasis.

Comparative StudyA simple modification for a longer and larger internal thoracic artery as a composite Y-graft.
Coronary artery bypass grafting (CABG) using bilateral internal thoracic artery (BITA) has been proven to improve survival. Many surgeons use the composite Y-graft which is made of left ITA (LITA) and right ITA (RITA) grafts. The LITA is typically anastomosed to left anterior descending artery (LAD). However, we have used RITA for LAD instead of LITA and reviewed the patency of ITA grafts and their clinical outcomes. ⋯ The clinical outcome of RITA to LAD anastomosis is comparable with anastomosis of LITA to LAD in CABG using BITA composite Y-grafts. This technique may be useful when longer and larger ITA grafts are needed.

Polymorphisms and high on-aspirin platelet reactivity after off-pump coronary artery bypass grafting.
High on-aspirin residual platelet reactivity (RPR) after coronary artery bypass grafting (CABG) is a transient phenomenon with important implications for graft patency. This study was designed to determine the role of polymorphisms [TBXA2R (T924C), GPIIIa (Pl(A1/A2)), P2Y1 (A1622G), and GP1Bα (C1018T)] on RPR in Chinese patients undergoing off-pump CABG (OPCAB). ⋯ High on-aspirin RPR after OPCAB is associated with genetic polymorphism TBXA2R-924TT and obesity.

Long-term left ventricular support in patients with a mechanical aortic valve.
The presence of a mechanical prosthesis has been regarded as an increased risk of thromboembolic complications and as a relative contraindication for a left ventricular assist device (LVAD). Five patients in our center had a mechanical aortic valve at the time of device implantation and were studied regarding thromboembolic complications. ⋯ The strategy of leaving a mechanical heart valve in place at the time of LVAD implantation in five patients led to valvular thrombosis in three but did not provoke embolic events. It increased the complexity of postoperative anticoagulation.

Comparative Study Observational StudyAvoidance of noninfectious sternal dehiscence: figure-of-8 wiring is superior to straight wire closure.
Comparison of figure-of-8 wiring or simple straight-wiring technique assessed by the frequency of early noninfectious sternal dehiscence. ⋯ In a large cohort of consecutive cardiac operations, it was found that sternal closure with figure-of-8 wires is better than closure with simple interrupted wires.
