Management of Intraoperative Fluid Balance and Blood Conservation Techniques in Adult Cardiac Surgery
This review discusses currently available techniques that can be used intraoperatively in an attempt to avoid or minimize fluid balance positiveness, to preserve the patient's own red blood cells, and to decrease blood product utilization during cardiac surgery.
Limited Blood Transfusion Does Not Impact Survival in Octogenarians Undergoing Cardiac Operations
Octogenarians receive RBCs more often than do younger patients. Although transfusion of 1 to 2 units of RBCs increases the risk of early death in patients younger than 80 years, this effect was not present among octogenarians. There was no significant effect of RBCs in late death in either age group.
Hemoglobin-Driven Pathophysiology is an in Vivo Consequence of the Red Blood Cell Storage Lesion that can be Attenuated in Guinea Pigs by Haptoglobin Therapy
Pathologies observed after transfusion with old blood, together with the favorable response to Hp supplementation, allowed us to define the in vivo consequences of the rbc storage lesion as storage-related posttransfusion hemolysis producing Hb-driven pathophysiology. Hb sequestration by Hp might therefore be a therapeutic modality for enhancing transfusion safety in severely ill or massively transfused patients.
Second Valve Implantation for the Treatment of a Malpositioned Transcatheter Aortic Valve
TAVI-in-TAV for correction of malpositioned or embolized valves is technically feasible and leads to favorable functional results during mid-term follow-up.
Peri-aortic Hematoma Complicated with Aortic Regurgitation Following Transcatheter Aortic Valve Implantation: Description of a Novel Mechanism of Paravalvular Leak
The present case describes a novel complication associated with TAVI, a severe paravalvular leak related to "stretch-induced" peri-aortic hematoma.
Indication and Structures and Management of Transcatheter Aortic Valve Implantation: A Review of the Literature
Currently, TAVI should be restricted to patients with severe symptomatic aortic valve stenosis and contraindications against open heart surgery or maximum perioperative risk. The surgical risk should be assessed by a multidisciplinary team. The procedure should be performed by interdisciplinary heart teams in hospitals with a cardiac surgery unit.
Automatic Aorta Segmentation and Valve Landmark Detection in C-Arm CT for Transcatheter Aortic Valve Implantation
Under the guidance of the automatically extracted patient-specific aorta model, the physicians can properly determine the C-arm angulation and deploy the prosthetic valve. Promising outcomes have been achieved in real clinical applications.
Data Collection and Interpretation in Blood Management (EP Video)
Dr. Mark Popovsky discusses the collection and interpretation of data in a blood management program (43:34 minutes).
TEG: Total Excellence Guaranteed
The TEG 5000 Hemostasis Analyzer provides the clinician with a complete picture of an individual patient’s hemostasis profile; thus guiding therapy and a targeted treatment: Right product, Right does, Right patient, Right time. This baseline test lets the clinician know if the patient is hypercoagulable, normal, hypocoagulable, or fibrinolytic.
Hemolytic and Thrombocytopathic Characteristics of Extracorporeal Membrane Oxygenation Systems at Simulated Flow Rate for Neonates
A state-of-the-art centrifugal pump combined with hollow-fiber oxygenator for extracorporeal membrane oxygenation has potential advantages such as smaller priming volumes and decreased potential to cause tubing rupture as compared with the traditional roller head/silicone membrane systems.
Clinical Evaluation of New Generation Oxygenators With Integrated Arterial Line Filters for Cardiopulmonary Bypass
New generation oxygenators with integrated arterial line filters have been marketed to improve the efficacy of cardiopulmonary bypass (CPB).
