Major findings of this study include the following: (1) early severe RVF affected one-quarter of the study cohort with high mortality, (2) the supervised machine learning–based STOP-RVF score successfully identified patients at risk of RVF after continuous-flow LVAD implantation, and (3) adding intraoperative characteristics did not enhance ...

2015年6月1日 · The Michigan score performed best for RVF discrimination (C = 0.62; 95% confidence interval [CI] 0.52 to 0.72; p = 0.021) and was the only score that reached statistical significance for RVF prediction with the original (derivation) definition in our cohort. A common feature across scores was the higher specificity compared with sensitivity ...

2008年6月3日 · Using a large LVAD database, we evaluated over 80 pre-operative variables to identify independent predictors of RV failure. We then created a right ventricular failure risk score (RVFRS) to better stratify RV failure risk in LVAD candidates.

The assessment of RVF is important in CTRCD, and its quantification should be included in clinical follow-up during cancer treatment. ... Additionally, tricuspid annular plane systolic excursion was significantly reduced (MD=-1.44mm [95% CI: -1.94, -0.95]) and pulmonary artery systolic pressure was significantly higher (MD=1.60mmHg [95% CI: 0. ...

Right ventricular failure (RVF) after left ventricular assist devices is associated with significant morbidity and mortality. Therefore, identifying patients at risk for severe RVF is important for clinical decision‐making.

Methods and results: RVF was defined as use of inotropes for >14 days, inhaled pulmonary vasodilators for >48 hours or unplanned right ventricular mechanical support postoperatively during the index hospitalization. Risk models were evaluated for the primary outcome of RVF by means of logistic regression and receiver operating characteristic ...

2021年8月9日 · An elevated EUROMACS score was associated with increased risk of RVF (OR 6.88; 95% CI 2.31 to 20.45, p = 0.001). The EUROMACS score had an area under the curve of 59%, (95% CI 52–66%) (Fig. 2 ). The performance of the EUROMACS score to predict RVF as defined by RVAD use or prolonged inotrope use was 67% (95% CI 54–79).

2015年5月1日 · Right ventricular failure (RVF) is a major cause of morbidity and mortality in left ventricular assist device (LVAD) recipients. To identify preoperative echocardiographic predictors of post-LVAD RVF. Data were collected for 42 patients …

Results: Overall, 37 patients (31.9%) developed RVF, defined: as pulmonary vasodilator use for ≥48 hours or inotrope use for ≥14 days post-operatively; re-institution of inotropes; multi-organ failure due to RVF; or need for mechanical RV support.

2024年3月1日 · The STOP-RVF risk calculator exhibited a significantly better performance than commonly used risk scores proposed by Kormos et al (C statistic, 0.58; 95% CI, 0.53-0.63) and Drakos et al (C statistic, 0.62; 95% CI, 0.57-0.67).
