30. The utility of temporal trends of blood biomarkers as predictors for bloodstream infections in left ventricular assist device recipients.

Author

Abstract

Background: Temporal trends of routinely obtained parameters may provide valuable information for predicting BSIs, but this association has not yet been established in LVAD patients. Methods: This retrospective analysis included data from 347 consecutive recipients of three rotary LVAD types. Study endpoints included the incidence of BSI, the association of temporal trends of routinely obtained blood biomarkers with the development of BSIs, the incidence of BSIs, and survival on LVAD support. Results: During follow‐up, 47.8% (n = 166) of the patients developed BSI. In multivariate analyses, the development of BSI was a significant predictor of mortality (HR 5.78, 95% CI 4.08–8.19, p < 0.0001). In univariate analyses, after adjusting for potential confounders, albumin (SHR 0.94, 95% CI 0.91–0.97, p < 0.00010), creatinine (SHR 1.49, 95% CI 1.03–2.15, p = 0.033), and C‐reactive protein (SHR 1.19, 95% CI 1.08–1.32, p = 0.0007) significantly predicted the development of BSIs during LVAD support. Notably, the strength of the association of parameter changes with the prediction of BSIs demonstrated a time‐dependent correlation in the cases of albumin (p = 0.045) and creatinine (p = 0.003). Conclusion: Bloodstream infections are highly prevalent among LVAD recipients and are independent predictors of mortality. Temporal biomarker trends significantly predict the development of BSIs. These findings suggest opportunities for interventions aiming to reduce the incidence of BSIs. [ABSTRACT FROM AUTHOR]

Abstract

Background: Left ventricular assist device (LVAD) malposition has been linked to hemocompatibility‐related adverse events (HRAEs). This study aimed to identify preoperative anatomical landmarks and postoperative pump position, associated with HRAEs during LVAD support. Methods: Pre‐ and postoperative chest X‐ray measures (≤14 days pre‐implantation, first postoperative standing, 6, 12, 18, and 24 months post‐implantation) were analyzed for their association with HRAEs over 24 months in 33 HeartMate 3 (HM3) patients (15.2% female, age 66 (9.5) years). Results: HM3 patients with any HRAE showed significantly lower preoperative distances between left ventricle and thoracic outline (dLVT) (25.3 ± 10.2 mm vs. 40.3 ± 15.5 mm, p = 0.004). A ROC‐derived cutoff dLVT ≤ 29.2 mm provided 85.7% sensitivity and 72.2% specificity predicting any HRAE during HM3 support (76.2% (>29.2 mm) vs. 16.7% (≤29.2 mm) freedom from HRAE, p < 0.001) and significant differences in cardiothoracic ratio (0.58 ± 0.04 vs. 0.62 ± 0.04, p = 0.045). Postoperative X‐rays indicated lower pump depths in patients with ischemic strokes (9.1 ± 16.2 mm vs. 38.0 ± 18.5 mm, p = 0.007), reduced freedom from any neurological event (pump depth ≤ 28.7 mm: 45.5% vs. 94.1%, p = 0.004), and a significant correlation between pump depth and inflow cannula angle (r = 0.66, p < 0.001). Longitudinal changes were observed in heart‐pump width (F(4,60) = 5.61, p < 0.001). Conclusion: Preoperative X‐ray markers are associated with postoperative HRAE occurrence. Applying this knowledge in clinical practice may enhance risk stratification, guide therapy optimization, and improve HM3 recipient management. [ABSTRACT FROM AUTHOR]

Abstract

Background: Patients with a HeartMate 3 (HM3) left ventricular assist device (LVAD) typically receive anticoagulation and antiplatelet therapy. The HM3 has shown a marked reduction in hemocompatibility-related adverse events (HRAEs) like stroke, bleeding, and pump thrombosis. This study evaluated whether aspirin (ASA) response influences HRAE incidence and if ASA sensitivity changes over time in HM3 recipients. Methods: This single-center, cross-sectional study included 32 HM3 patients (age: 59.0 ± 10.0 years, 15.6% female). ASA sensitivity was assessed twice using the VerifyNow assay, with ASA resistance defined by ASA reactivity units (ARU) > 550. The primary endpoint was HRAE incidence in ASA responders vs. non-responders over two consecutive follow-ups; the secondary endpoint was temporal changes in ASA resistance. Results: At the first follow-up, 13 (40.6%) patients were ASA-resistant, and 8 (28.6%) were resistant at the second follow-up, without significant change (p = 0.22). ASA non-responders and responders had similar ASA doses and baseline characteristics. No significant difference in HRAE incidence was found between ASA non-responders and responders (0.0% vs. 15.8%, p = 0.14), and no additional HRAEs occurred during follow-up. Conclusions: ASA resistance varied considerably among HM3 patients without significant temporal changes, and the demonstrated excellent hemocompatibility supports recent evidence that ASA may have a limited role in the antithrombotic regimen for HM3 recipients.

Abstract

Aims: This EUROMACS study was conducted with the primary aim of investigating the association between a centre's annual caseload and postoperative outcomes among patients undergoing left ventricular assist device (LVAD) implantation. Methods and results: A total of 4802 patients identified between 2011 and 2020 from 35 participating centres were dichotomized based on the annual caseload of the treating centre at the time of device implant (≤30 vs. >30 LVAD implantations/year). The primary endpoint was 1‐year survival. Secondary outcomes included overall survival analysis, device‐related adverse events and readmissions. Cumulative follow‐up was 10 003 patient‐years, with a median follow‐up of 1.54 years (interquartile range 0.52–3.15). Patients from higher volume centres more frequently presented in INTERMACS levels 1 and 2, suffered from right heart dysfunction and needed inotropic support. No difference was observed in adjusted 1‐year survival. Adjusted overall survival probability was lower in higher volume centres (p = 0.002). In the subgroup analysis of HeartMate 3 devices only, higher volume centres were associated with decreased odds of 1‐year survival (adjusted odds ratio 0.43, 95% confidence interval 0.20–0.97, p = 0.041). Similar findings were observed in the cumulative (i.e. learning curve) caseload analyses. Conclusion: In patients undergoing LVAD implantation, centre volume was not associated with 1‐year survival, but was related to device‐related adverse events. Patient profiles differed with respect to centre size. These findings underscore the necessity for ongoing quality improvement initiatives in all centres, regardless of their annual caseload. Efforts are needed to standardize patient selection and preconditioning to further improve patient outcome. [ABSTRACT FROM AUTHOR]

Abstract

Background: Stroke after durable left ventricular assist device (d‐LVAD) implantation portends high mortality. The incidence of ischemic and hemorrhagic stroke and the impact on stroke outcomes of temporary mechanical circulatory support (tMCS) management among patients requiring bridge to d‐LVAD with micro‐axial flow‐pump (mAFP, Abiomed) is unsettled. Methods: Consecutive patients, who underwent d‐LVAD implantation after being bridged with mAFP at 19 institutions, were retrospectively included. The incidence of early ischemic and hemorrhagic stroke after d‐LVAD implantation (<60 days) and association of pre‐d‐LVAD characteristics and peri‐procedural management with a specific focus on tMCS strategies were studied. Results: Among 341 patients, who underwent d‐LVAD implantation after mAFP implantation (male gender 83.6%, age 58 [48–65] years, mAFP 5.0/5.5 72.4%), the early ischemic stroke incidence was 10.8% and early hemorrhagic stroke 2.9%. The tMCS characteristics (type of mAFP device and access, support duration, upgrade from intra‐aortic balloon pump, ECMELLA, ECMELLA at d‐LVAD implantation, hemolysis, and bleeding) were not associated with ischemic stroke after d‐LVAD implant. Conversely, the device model (mAFP 2.5/CP vs. mAFP 5.0/5.5: HR 5.6, 95%CI 1.4–22.7, p = 0.015), hemolysis on mAFP support (HR 10.5, 95% CI 1.3–85.3, p = 0.028) and ECMELLA at d‐LVAD implantation (HR 5.0, 95% CI 1.4–18.7, p = 0.016) were associated with increased risk of hemorrhagic stroke after d‐LVAD implantation. Both early ischemic (HR 2.7, 95% CI 1.9–4.5, p < 0.001) and hemorrhagic (HR 3.43, 95% CI 1.49–7.88, p = 0.004) stroke were associated with increased 1‐year mortality. Conclusions: Among patients undergoing d‐LVAD implantation following mAFP support, tMCS characteristics do not impact ischemic stroke occurrence, while several factors are associated with hemorrhagic stroke suggesting a proactive treatment target to reduce this complication.

Abstract

Cardiac myxomas in the right ventricle are a very rare condition. In this case report, we describe an exceptionally uncommon case involving a right ventricular cardiac myxoma, originating from a papillary muscle, extending to both the tricuspid valve and the right atrium. The valve was able to be repaired via artificial chorda implantation. [ABSTRACT FROM AUTHOR]
