We evaluated our experience with axillary artery perfusion technique in acute type A aortic dissection repair. ⋯ Right axillary artery cannulation for repair of acute type A aortic dissection is a simple and safe procedure. In the case of pulselessness of right upper limb, femoral artery is still the choice of cannulation site.

In patients with ischemic left ventricular dysfunction and functional mitral regurgitation, the surgical treatment of the mitral insufficiency remains a challenging issue. Several procedures were described to restore a more normal alignment between the mitral annulus and the laterally displaced papillary muscles. We report a new approach to relocate the displaced papillary toward the mitral annulus and to reduce tethering. This procedure is believed to be technically easy and beneficial in terms of mitral repair.

Acute fulminant myocarditis can cause left ventricular dysfunction that predisposes the patients to critical condition. Left ventricular assist device (LVAD) is a useful option for the patient whose condition is resistant to medical therapy. However, when right ventricular dysfunction with hypoxia is complicated with left ventricular dysfunction, it can be difficult to make a prompt decision in order to achieve better outcome. We present our case in which the support on LVAD and extracorporeal membrane oxygenation (ECMO) was effective to treat critically ill patients.

Real-time readings of the regional oxygen saturation (rSO(2)) using near-infrared spectroscopy (NIRS) during the aortic arch surgery can provide an early detection of perfusion or oxygenation abnormalities. ⋯ Continuous monitorization of the cerebral O(2) saturation during aortic arch surgery in adults and infants is a feasible technique to control an adequate cannula positioning and to optimize clinical outcomes avoiding neurological complications related to cerebral malperfusion.

Comparative Study
Kinetic of procalcitonin in the early postoperative course following heart transplantation.
It was the aim of the study to determine the kinetics of procalcitonin (PCT) levels following heart transplantation (HTx) and to investigate the prognostic suitability of postoperative changes in PCT levels for patients' outcome. ⋯ PCT levels have been consistently low (<10 ng/mL) in patients with an uneventful course, but more frequently increased in patients with postoperative complications and even associated with an increased mortality early postoperatively when values exceed 80 ng/mL. As a clinical consequence, PCT levels in the first few days following cardiac transplantation can help to identify patients at risk, when concentrations exceed the "normal" posttransplant range.
