Blood Hemolysis

Multi-Method Investigation of Blood Damage Induced by Blood Pumps in Different Clinical Support Modes

This study investigates the impact of different operational modes of an extracorporeal blood pump (CentriMag) on blood flow patterns and the associated risks of bleeding, thrombosis, and hemolysis using computational fluid dynamics and hemocompatibility models. It finds that venous-arterial (V-A) ECMO mode results in the highest risk of these complications, with heart failure (HF) mode being the least risky, largely due to variations in flow patterns affecting cell and protein functions.

Outcomes of Total Aortic Arch Replacement in a Canadian Nationwide Registry

This multicenter study compares outcomes of 250 elective total arch replacements with 728 elective hemiarch replacements in Canada, using propensity score matching to create 202 well-matched pairs. Findings reveal that while in-hospital mortality rates for total arch replacement are comparable to hemiarch repairs, total arch replacement is associated with higher rates of complications such as delirium and prolonged intubation.

The Usefulness of Contrast Echocardiography in the Evaluation of Cardiac Masses: A Multicenter Study

This study evaluates the diagnostic accuracy of Contrast Echocardiography (CE) in differentiating between thrombi, benign, and malignant cardiac masses, using a multicenter prospective approach on 145 patients. The results indicate high accuracy of CE, with optimal A1/A2 cutoff values showing strong sensitivity and specificity in distinguishing different types of cardiac masses.
