ReviewBleeding and Thrombotic Events in Patients Undergoing Mechanical Circulatory Support: A Review of Literature.
Bleeding and thrombotic events are among the most common complications detected in patients with mechanical circulatory support (MCS). Herein, we reviewed the available evidence on the prevalence, etiology, and management of bleeding and thrombotic events in patients following MCS procedures, such as implantation of both intra- and paracorporeal devices that generate either pulsatile or nonpulsatile flow. Extracorporeal life support procedures providing support to the failing heart and lungs were also reviewed. ⋯ To provide advanced understanding of hemostatic disturbances during MCS, prospective trials focused on bleeding and thromboembolic events as primary endpoints should be conducted. Better understanding of the underlying pathophysiology and a shift towards a personalized approach based on functional point-of-care hemostatic properties assessment may provide more favorable clinical outcomes. This should, however, be coupled with further technological improvements providing better device surface hemocompatibility as interaction between blood and device surface affects the hemostatic equilibrium.

Comparative StudyComparison of the Avalon Dual-Lumen Cannula with Conventional Cannulation Technique for Venovenous Extracorporeal Membrane Oxygenation.
Comparison of two kinds of cannulation (double-lumen cannula [DLC, Avalon Elite Bicaval Dual Lumen Catheter] and conventional cannulation with two cannulas) for venovenous extracorporeal membrane oxygenation (ECMO) therapy in terms of effectiveness, usage complexity, and costs. ⋯ In summary, double-lumen cannulation allows sufficient gas exchange with more effort (material, technical, and physicians' experience) and higher costs but better mobilization possibilities (particularly prone position) and potential avoidance of deep sedation and mechanical ventilation. From the current point of view, the DLC should be reserved for special cases.

Comparative StudyHeart Transplantation in Patients Older than 65 Years: Worthwhile or Wastage of Organs?
Patients older than 65 years have traditionally not been considered candidates for heart transplantation. However, recent studies have shown similar survival. We evaluated immediate and medium-term results in patients older than 65 years compared with younger patients. ⋯ Heart transplantation in selected older patients can be performed with survival similar to younger patients, hence should not be restricted arbitrarily. Incidence of infections, graft vascular disease, and malignancies can be reduced with a more personalized approach to immunosuppression. Allocation of donors to these patients does not appear to reduce the possibility of transplanting younger patients.

Comparative StudyThe Munich Lung Transplant Group: Intraoperative Extracorporeal Circulation in Lung Transplantation.
This retrospective single-center study aimed to analyze transfusion requirements, coagulation parameters, and outcome parameters in patients undergoing lung transplantation (LuTx) with intraoperative extracorporeal circulatory support, comparing cardiopulmonary bypass (CPB), and extracorporeal membrane oxygenation (ECMO). ⋯ These data indicate a perioperative advantage of ECMO usage with low-dose heparinization over conventional CPB for extracorporeal circulatory support during LuTx. Long-term outcome is not affected.
