Randomized Controlled Trial Multicenter Study Comparative Study
Results of low-dose carperitide infusion in high-risk patients undergoing coronary artery bypass grafting.
This study investigated the efficacy of human atrial natriuretic peptide (hANP, carperitide) for high-risk patients undergoing coronary artery bypass grafting (CABG). ⋯ In the early postoperative period, carperitide has a cardiorenal protective effect that prevents postoperative MACCE and hemodialysis. Perioperative low-dose carperitide infusion may be useful in high-risk patients undergoing on-pump CABG.

Randomized Controlled Trial Comparative Study
The no-touch saphenous vein as the preferred second conduit for coronary artery bypass grafting.
Injury incurred while saphenous veins are being obtained results in poor graft patency and impairs the results of coronary artery bypass grafting. A novel method of obtaining veins, the no-touch technique, has shown improved long-term saphenous vein graft patency. ⋯ No-touch saphenous vein grafts showed a significantly higher patency rate than the radial artery grafts and the patency was comparable to the patency for left internal thoracic artery grafts. This highlights the improvement in saphenous vein graft quality with the no-touch technique and increases the number of situations in which saphenous veins may be preferable to radial artery grafts as conduits in coronary artery bypass grafting.

Multicenter Study Comparative Study
The Perceval S aortic valve has the potential of shortening surgical time: does it also result in improved outcome?
Sutureless aortic valve prostheses have the potential of shortening surgical time. However, whether shorter operative times may also result in improved patient outcomes remains to be established. ⋯ Sutureless implantation of the Perceval valve is associated with shorter cross-clamp and cardiopulmonary bypass times, resulting in improved clinical outcome. In addition, it compares favorably with conventional valves in terms of mortality and outcome variables.

Comparative Study
Hypoxemia during one-lung ventilation for robot-assisted coronary artery bypass graft surgery.
Robot-assisted coronary artery bypass grafting requires continuous one-lung ventilation (OLV) to evacuate the thoracic cavity. Whether this ventilatory mode subjects patients to serious hypoxemia remains underinvestigated. ⋯ Robot-assisted two-stage coronary artery bypass surgery employing OLV could be complicated by serious hypoxemia especially at the minithoracotomy grafting stage and in patients with specific risk factors. Thus, when managing such patients, invasive monitoring and aggressive treatment of arterial desaturation are mandatory to ensure the patient's safety and procedural smoothness.
