Randomized Controlled TrialTrimetazidine may protect the myocardium during cardiac surgery.
Trimetazidine is an anti-ischemic agent with cardioprotective effects. The purpose of this double-blind, controlled, prospective randomized study was to investigate the possible effects of the preoperative use of trimetazidine on the biochemical markers of myocardial injury during open heart surgery and to determine if it has any myocardial protective effects. ⋯ We conclude that pretreatment with trimetazidine has some beneficial effects in protecting the myocardium and decreasing myocardial injury during the cardioplegic arrest period in open heart surgery without affecting postoperative hemodynamics.

Case ReportsComminuted sternal fracture -- a sternotomy wire fixation: report of 2 cases.
Various techniques of sternal stabilization via either metal plates or wires have been described. We describe an alternative technique of simple median sternotomy followed by reduction and wire fixation of the sternal fracture. The 2 patients described in this report had traumatic comminuted and displaced sternal fractures. Even though wire repair was deemed to be tedious and achieved poor approximation of the bone, we performed median sternotomy and achieved simple wire fixation with an excellent result.

Case ReportsA rare combination of left main coronary artery fistula to main pulmonary artery with severe left main coronary artery disease in a 69-year-old man.
A 69-year-old man was referred to our hospital with a diagnosis of non-ST elevation myocardial infarction. A selective left coronary angiography revealed a fistula connecting the left main coronary artery with the pulmonary artery in addition to severe left main coronary artery disease. The patient subsequently underwent ligation of fistulae and coronary bypass grafting. The combination of a fistula and severe artery disease seen in this patient is unusual because fistulas originating from the left main coronary artery drain into the pulmonary artery in patients with severe left main coronary artery disease.

Planning a cardiovascular hybrid operating room: the technical point of view.
The integration of interventional techniques into cardiovascular surgery requires angiographic imaging capabilities in the operating room. A deep understanding of the technology and its implication for the surgical workflow is scarce. ⋯ With the growing trend toward endovascular procedures during surgery, the hybrid operating room will become an integral part of every cardiovascular center. This new operating room concept enables new cardiac surgery therapies and will play a vital role for minimally invasive surgery. Careful planning and professional expertise is a key factor for every hybrid room project.

Clinical TrialRepeat surgery for coronary artery bypass grafting: the role of the left thoracotomy approach.
Repeat coronary artery bypass surgery has increased risks compared with the first operation, including low cardiac output and injury to patent grafts. The left thoracotomy approach has been advocated specifically in patients with intact grafts of the left internal mammary artery (LIMA) to the left anterior descending coronary artery (LAD) needing lateral wall grafting. We have evaluated this technique in conjunction with an off-pump procedure in all patients. ⋯ The procedure is safe, especially in patients with intact LIMA-to-LAD grafts needing lateral and inferior wall revascularization. Multislice computed tomography scanning allows better preoperative planning, especially regarding the site of implantation of the proximal graft, allowing a less invasive incision. The off-pump technique preserves cardiac and pulmonary function. The in-hospital death rate (1.8%) compares very well with the EuroSCORE-predicted mortality (14.2%).
