Outcomes in Patients Requiring VENO‐Venous Extracorporeal Membrane Oxygenation After Cardiac Surgery: An Analysis From the PELS‐1 Study

Artificial Organs, EarlyView.
We report an insight from the PELS‐1– a multicentre, international registry focusing on postocardiotomy extracorporeal support use between 2000 and 2020. We focused on 24/2163 (1.1%) patients requiring V‐V ECMO after cardiac surgery. Mortality was high, with 21.7% of patients discharged alive and an overall 1‐year survival probability of 12.5 ...

Validation of Aortic Blood Flow Simulations During Extracorporeal Circulation Using Phase Contrast Magnetic Resonance Imaging

Artificial Organs, EarlyView.
This is the first study assessing in vivo blood flow profiles during extracorporeal circulation (ECC) scenarios. Magnetic resonance imaging data served for the calibration of computational fluid dynamics algorithms, enabling accurate replication of the hemodynamic conditions.

[Prognostication of the outcome of heart valve prosthesis implantation by the method of nonlinear chaos dynamics of the heart rate].

Vestnik khirurgii imeni I. I. Grekova, 2001
An examination of 39 patients with heart diseases was performed before and after operations by the method of geometrical analysis of the nonlinear chaos (fractal) variability of the cardiac rhythm on the basis of the apparatus-programmed complex "Poly-spectrum". Five-minute-long registrations of ECG were carried on.

Comparison of Intraoperative Doppler Flow Measurements and Algorithmic Flow Estimations in Patients Undergoing Durable Left Ventricular Assist Device Implantation

Artificial Organs, EarlyView.
Direct intraoperative HeartMate 3 LVAD flow measurements using an ultrasonic probe revealed consistently higher values by approximately 0.5 L/min compared to device‐estimated flows. This discrepancy remained stable across pump speed settings, highlighting the importance of distinguishing measured from estimated flow in HeartMate 3 patients.

Identification of Autologous Tissue Sources and Optimization of a Treatment Method for Intraoperative Manufacturing of Heart Valve Constructs

Artificial Organs, EarlyView.
The use of autologous connective tissue, such as pericardium or peritoneum, combined with controlled tissue treatment, has the potential to result in a more durable heart valve prosthesis than current commercial prostheses. ABSTRACT Introduction Valvular heart disease remains a leading cause of morbidity and mortality. Current biological and mechanical
