Interaction Between Platelet and Fibrinogen on Clot Strength in Healthy Patients.
The purpose of this study was to explore the relationship between platelet concentration (PLT) (× 109/L) and clot strength measured by thromboelastography maximum amplitude (TEG-MA) in healthy volunteers without a history of coagulation abnormalities. Secondarily, the relationship between fibrinogen (mg/dL) and TEG-MA was analyzed. ⋯ In healthy patients, a PLT of 60 × 109/L was associated with normal clot strength (TEG-MA ≥53 mm), and there was little change in clot strength with PLT >90 × 109/L. Although prior analyses described the contributions of platelets and fibrinogen toward clot strength, they are presented and discussed independently. The data above described clot strength as an interaction among them. Future analyses and clinical care should evaluate and recognize the interplay.

Observational StudyPoint-of-Care Viscoelastic Hemostatic Assays in Cardiac Surgery Patients: Comparison of Thromboelastography 6S, Thromboelastometry Sigma, and Quantra.
Viscoelastic tests allow a reduction in blood product transfusion. Three modern devices are currently available (rotational thromboelastometry [ROTEM] sigma, thromboelastography [TEG] 6S, and Quantra). No study has compared the performances of these 3 devices simultaneously. ⋯ ROTEM sigma, TEG 6S, and Quantra performed similarly for exploring platelet count or residual circulating heparin. Thromboelastography 6S presented a weaker correlation with fibrinogen Clauss.

The Use of Contrast May Improve Aortic Valve Assessment During Transesophageal Echocardiography.
The Doppler profile that quantifies the degree of aortic stenosis is essential, as an inaccurate measurement can alter the surgical plan. The authors aimed to examine the level of agreement between the contrast and noncontrast methods of aortic valve sizing during intraoperative transesophageal echocardiography (TEE). ⋯ This discrepancy is significant and could affect the decision to replace the aortic valve. When evaluating the aortic valve with TEE, the authors recommend using a contrast agent to improve the Doppler profile and to obtain a more accurate measurement of the aortic valve area.
