    Article Snippet: The report in this issue of the Journal from Han and colleagues from Columbia University describes a singleinstitutional retrospective analysis of patients implanted with continuous flow LVADs (90% HeartMate II, 10% HeartWare and others), comparing characteristics and outcomes of those with and without tricuspid intervention (mostly ring annuloplasty).

    Article Snippet: A more recent study of 524 patients implanted with continuous flow LVADs (403 Heart Mate II, 123 HeartWare) demonstrated lower survival at 1, 3, 6, 12 and 24 months (P<0.001 for all) and increased risk of early right heart failure and infections in those with MELD-XI score of 14 or more, compared to patients with a MELD-XI score of less than 14 ( 58 ).

    Article Title: Abstracts of the Heart Failure 2016 Conference, Florence, Italy, 21-24 May 2016.
    Article Snippet: Heart failure can occur in any age, no depend on sex, but in men and women the mechanism, even if is the same, the fact is that the compromise on pumping function is diferent.. AIM We realized a follow-up with 100 female patients during hospitalization with heart failure as a mean diagnostic.. These are patient between 60 and 75 years old, with different pathologies: diabetes mellitus, arterial hypertension, obesity, atrial fibrillation, and hypothyroidism.

    Comparison of discrimination of risk scores. Kalogeropoulos et al. compared existing risk scores in 116 patients with continuous-flow LVAD, either the HeartMate II (Thoratec, Inc.) or the HeartWare HVAD (Heart-Ware, Inc.), in single center. Although the Michigan score showed the highest value, the C-indexes of all scores remained around 0.6.
