Progress of extracorporeal centrifugal pumps for mechanical circulatory supports.
J Artif Organs

This review traces the evolution of centrifugal blood pumps in mechanical circulatory support (MCS) systems. Initially met with concerns over blood damage and thrombus formation, centrifugal pumps have become crucial components in ventricular assist devices (VADs) and extracorporeal membrane oxygenation (ECMO) due to their simplified drive mechanisms and adaptability. This paper outlines three generations of centrifugal pump development: first-generation pumps with sealing components, second-generation pumps utilizing pivot bearings, and third-generation pumps employing contactless bearings.

Objectives: The UK has recently established subscription-payment agreements for two antimicrobials: cefiderocol and ceftazidime-avibactam. This article summarises the novel value assessments that informed this process and lessons learned for future pricing and funding decisions.
Methods: The evaluations used decision modelling to predict population incremental net health effects (INHEs), informed by systematic reviews, evidence syntheses, national surveillance data and structured expert elicitation.
Effects of Concomitant Intra-Aortic Balloon Pump Usage and Different Cannulation Techniques on Venoarterial Extracorporeal Membrane Oxygenation Support in Terms of Organ Perfusion.
Braz J Cardiovasc Surg
November 2024
Cardiovascular Surgery Department, Health Science University, Kosuyolu High Specialization Education and Research Hospital, İstanbul, Turkiye.
Article Synopsis
- The study investigates different strategies for venoarterial extracorporeal membrane oxygenation (V-A ECMO) in patients, examining the effectiveness of various cannulation sites and the use of intra-aortic balloon pump (IABP).
- Researchers categorized patients into two main groups: those receiving isolated V-A ECMO and those receiving V-A ECMO with IABP, and further divided them based on cannulation sites (e.g., central, axillo-femoral).
- Results showed no significant differences in organ perfusion across the different cannulation sites or with IABP support, suggesting that the choice of cannulation site should be tailored to individual patient needs rather than based on a one-size-fits-all approach
Left ventricle unloading during veno-arterial extracorporeal membrane oxygenation: review with updated evidence.
Acute Crit Care
November 2024
Department of Thoracic and Cardiovascular Surgery, Chonnam National University Hospital, Chonnam National University Medical School, Gwangju, Korea.
Article Synopsis
- * While VA-ECMO is beneficial, it can cause issues like left ventricular (LV) overload due to increased retrograde arterial flow, leading to complications like pulmonary edema and arrhythmias.
- * Effective management of VA-ECMO requires LV unloading to mitigate these risks; the article discusses the timing, indications, and methods for achieving this unloading.
