Despite receiving intensive treatment, his condition deteriorated. Preoperative evaluation revealed significant systemic right ventricular dysfunction with severe valvular regurgitation and pulmonary hypertension. The surgical approach included tricuspid and aortic bioprosthetic valve replacement, mitral valve annuloplasty, and right thoracic ventricular assist device (VAD) implantation.

We characterized the in vitro removal performance of each filter in a 72 hour simulated CRRT procedure.

Vancomycin clearance remained stable for AN69 filters but decreased for HF1400. Interleukin (IL)-8 was removed primarily via adsorption with the AN69 filters (92.2 and 91.2 ml/minute for AN69-M and AN69-ST, respectively), but clearance was significantly lower with HF1400 (8.4 ml/minute). Tumor necrosis factor (TNF)-α clearance was higher with AN69-ST compared with AN69-M or HF1400 (10.3, 1.8, and 2.3 ml/minute, respectively). β 2 -microglobulin clearance was higher with both AN69-based filters.

A subpopulation requiring a system exchange and with long, exchange-free runs of the second oxygenator (≥7 days) (n = 110) was analyzed analogously. Patients with COVID-19 showed the highest platelet levels before ECMO implantation. Independent of the underlying disease and ECMO type, platelet counts decreased significantly within 24 hours and reached a steady state after 5 days. In the subpopulation, at the day of a system exchange, platelet counts were lower compared with ECMO start, but without differences between underlying diseases. Subsequently, platelets remained unchanged in the bacterial pneumonia group, but increased in the COVID-19 and viral pneumonia groups within 2-4 days, whereas D-dimers decreased and fibrinogen levels increased. Thus, overall platelet counts on V-V ECMO show disease-specific initial dynamics followed by an ongoing consumption by the ECMO device, which is not boosted by new artificial surfaces after a system exchange.","PeriodicalId":8844,"journal":{"name":"ASAIO Journal","volume":"71 6","pages":"498-509"},"PeriodicalIF":3.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12122090/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144198222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing RHF prediction scores are complex, typically requiring multiple indicators and evaluation steps. This research aimed to explore a more feasible predictor for initial screening of early RHF. This multicenter, retrospective analysis included 83 consecutively enrolled patients undergoing continuous-flow LVAD implantation. Multivariable logistic regression identified independent predictors of early RHF, whereas receiver operating characteristic (ROC) curve analysis assessed predictive value. Among the 83 patients, 21 (25.3%) experienced early RHF. Logistic regression analyses revealed that the direct bilirubin to total bilirubin (DBIL/TBIL) ratio on admission was significantly correlated with early RHF (adjusted odds ratio [OR]: 2.41, 95% confidence interval [CI]: 1.35-4.31, p = 0.003). The DBIL/TBIL ratio on admission exhibited the highest area under the receiver operating characteristic curve (AUC) (0.767, 95% CI: 0.661-0.852). Internal validation using bootstrap techniques resulted in a mean AUC of 0.767 (95% CI: 0.640-0.879), whereas external validation in a cohort of 31 patients demonstrated an AUC of 0.682 (95% CI: 0.491-0.837). An optimal DBIL/TBIL ratio threshold of 0.52 yielded 76.19% sensitivity and 79.03% specificity for early RHF prediction.

Aortic models with different outflow graft orientations were designed and three-dimensional (3D) printed to mimic common implantation configurations and were integrated into a pulsatile mock circulatory flow loop. Assist device function was achieved using a rotary pump, replicating nonpulsatile, continuous support flows of 1-5 L/min.
