Perioperative Predictors of Right Ventricular Failure Following Left Ventricular Assist Device Implantation.
, ASAIO JRight ventricular failure (RVF) is an important complication following implantation of a left ventricular assist device (LVAD) in patients with advanced heart failure. This study aims to identify perioperative hemodynamic predictors of RVF following LVAD implantation and develop an internally validated predictive model. Patients who underwent LVAD implantations between March 2013 and March 2023 at a large-volume tertiary center were retrospectively analyzed. The primary outcome was early post-implant RVF, defined by need for right ventricular assist device (RVAD), prolonged inotrope dependence (> 14 days), or death within 14 days while on inotropes. Perioperative hemodynamic variables were analyzed using univariate logistic regression. A prediction model was then developed using stepwise multivariate logistic regression, and internally validated using k-fold cross-validation. Among 210 patients, 73 patients (34.8%) developed early post-implant RVF. Decreased post-implant cardiac index (odds ratio [OR]: 0.0122, p = 0.001), decreased mean arterial pressure (OR: 0.932, p = 0.008), and simultaneously increased cardiac index and pulmonary pulse pressure (OR: 1.13, p = 0.021) independently predicted RVF. Preimplantation IV inotrope therapy was a significant confounder (OR: 3.96, p = 0.021). Our proposed predictive model achieved strong discriminatory power (area under the curve [AUC] of 0.830) and stable cross-validation performance. External validation with multicenter cohorts is warranted to confirm predictive accuracy and clinical applicability.

Efficacy and Safety of Very Low Achieved LDL-Cholesterol in Patients with Prior Ischemic Stroke.
, CirculationBACKGROUND: Patients with prior ischemic stroke are at high risk for recurrent stroke and other major adverse cardiovascular events (MACE). The benefits of achieving very low levels of low-density lipoproteins-cholesterol (LDL-C) in such patients is unclear. METHODS: We analyzed patients with prior ischemic stroke enrolled in FOURIER, a randomized placebo-controlled trial studying evolocumab in patients with stable atherosclerotic cardiovascular disease (median follow-up 2.2 years), and through the open-label extension (FOURIER-OLE) period (additional median follow-up 5 years), to examine the relationship between achieved LDL-C and the long-term incidence of the primary endpoint (cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina or coronary revascularization) and stroke-related endpoints. RESULTS: The analysis included 5,291 patients with prior ischemic stroke (more than 4 weeks old). A total of 666 (12.6%), 1410 (26.6%), 586 (11.1%), 508 (9.6%) and 2121 (40.1%) patients achieved LDL-C values of <20, 20 to <40, 40 to <55, 55 to <70 and ≥70 mg/dL, respectively. The incidence of the primary endpoint, all stroke, and ischemic stroke each decreased in a monotonic fashion with lower achieved LDL-C levels on a continuous scale (Ptrend <0.001, 0.002 and 0.002, respectively). Compared with patients with LDL-C ≥70 mg/dL, those who achieved levels <40 mg/dL had incidence rate ratios (IRRs) (95% CI) of 0.69 (0.57-0.84), 0.73 (0.53-0.99), and 0.75 (0.54-1.05) for the outcomes of the primary endpoint, all stroke, and ischemic stroke, respectively. Hemorrhagic strokes were infrequent and unrelated to achieved LDL-C (Ptrend=0.85). CONCLUSIONS: In patients with prior ischemic stroke, it appeared that the lower the LDL-C, down to levels below 40 mg/dL, the lower the risk of MACE, including recurrent stroke, without a clear increase in risk of hemorrhagic stroke. These findings support the concept that more intensive LDL-

Consensus-guided evaluation of self-supervised learning in echocardiographic segmentation.
, Comput Biol Med, Vol: 198BACKGROUND: Left ventricle segmentation is a fundamental task in echocardiography, essential for assessing cardiac function. However, deep learning models for segmentation rely on large labelled datasets, which are expensive and time-consuming to annotate. Self-supervised learning has emerged as a promising approach to leverage unlabelled data, but its effectiveness for left ventricle segmentation remains underexplored. METHODS: This study investigates self-supervised learning for echocardiographic segmentation, comparing various pretext tasks. The impact of dataset size and distribution on pre-training is examined, revealing that excessive unlabelled data can degrade performance due to redundancy and low variability. A novel multi-expert labelled dataset is introduced to enhance segmentation evaluation, using consensus-based annotations to reduce annotation noise and improve reliability. RESULTS: Among the self-supervised learning methods evaluated, contrastive learning consistently outperforms other approaches, particularly in low-label settings. The study demonstrates that AI models pre-trained using self-supervised learning and fine-tuned with only 15% of labelled data achieve stronger alignment with multi-expert consensus than any individual expert. CONCLUSION: The findings suggest that AI models can generalise well across expert annotations, providing more reliable and reproducible assessments.

Ventricular repolarization is improved by His resynchronization therapy but not biventricular pacing.
, Heart RhythmBACKGROUND: Biventricular pacing (BVP) delivered cardiac resynchronization therapy (CRT) modestly improves activation synchrony in patients with heart failure and left bundle branch block (LBBB) but can trigger ventricular arrhythmias. His bundle pacing (HBP) can correct LBBB as an alternative CRT method, producing superior ventricular activation synchrony and hemodynamics. OBJECTIVE: The aim of the study was to investigate the relative effects of HBP-CRT and BVP-CRT on ventricular repolarization. METHODS: Patients with LBBB referred for BVP-CRT underwent intra-procedural non-invasive epicardial mapping during atrial pacing (intrinsic LBBB), BVP-CRT, and temporary HBP. When HBP corrected LBBB, changes from baseline (LBBB) in overall and left ventricular (LV) repolarization dispersion (ΔVRT, ΔLVRT), repolarization gradient (ΔVRG, ΔLVRG) and activation-recovery interval (ARI) dispersion (ΔVARI, ΔLVARI) were measured. RESULTS: 17 patients had full datasets. BVP-CRT had no effect on global repolarization dispersion, gradient steepness or ARI (ΔVRT -1.5 ms, 95% confidence interval [CI] -15.4 to +12.4, P = .82; ΔVRG -0.00549 ms/mm, -0.106 to +0.0954, P = .9; ΔVARI -5.0 ms, -24.3 to +14.3, P = .59) and worsened the parameters in the LV (ΔLVRT +14.5 ms, +0.05 to +28.9, P = .049; ΔLVRG +0.0931 ms/mm, -0.0635 to +0.25, P = .226, ΔLVARI +28.6 ms, 95% CI +6.0 to +51.2, P = .02). HBP-CRT significantly improved global repolarization dispersion, gradient steepness and ARI (ΔLVRT +14.5 ms, +0.05 to +28.9, P = .049; ΔLVRG +0.0931 ms/mm, -0.0635 to +0.25, P = .226; ΔVARI -49.5 ms, -69.0 to -29.9, P < .0001) and within the LV (ΔLVRT -38.2 ms, -48.7 to -27.6, P < .001; ΔLVRG -0.228 ms/mm, -0.334 to -0.122, P = .0003; ΔLVARI -37.2 ms, -59.4 to -15.0, P = .003). CONCLUSION: HBP-CRT improves LBBB-induced repolarization abnormalities through improved activation synchrony and AR
