Myxomas comprise 50% of all benign cardiac tumors in adults, with the right atrium as their second most frequent site of origin. Surgical resection is the only effective therapeutic option for patients with these tumors. The association between right atrial myxomas and severe left ventricular systolic dysfunction is extremely rare and makes treatment even more challenging. This was the case for our patient, a 47-year-old male with a right atrial mass and a severely impaired left ventricular function, with a 20% ejection fraction. Global enlargement of the heart was also noted, with moderate right ventricular dysfunction. The tumor was successfully excised using the on-pump beating heart technique, with an immediate postoperative improvement of the left ventricular ejection fraction to 35%. The technique proved useful, with no increased risk to the patient.

Abstract Aims Midwall fractional shortening (MWFS) is a measure of left ventricular (LV) systolic function that is more reliable in case of concentric LV geometry compared to LV ejection fraction (LVEF). We hypothesized that MWFS might predict heart failure (HF) and death in a high-risk asymptomatic population, beyond other echocardiographic parameters. Methods and results Among 4047 subjects aged ≥55/≤80 years followed by 10 general practitioners in northern Italy, the DAVID-Berg study prospectively enrolled 623 asymptomatic outpatients at increased risk for HF. Baseline evaluation included clinical visit, electrocardiogram, N-terminal pro-brain natriuretic peptide (NT-proBNP), and echocardiogram. Mean age of the population was 69 ± 7 years, 56% were men, 88% had hypertension, mean LVEF was 61 ± 9%, and mean MWFS 16.2 ± 3.3. During a median follow-up of 5.7 years, 95 subjects experienced HF/death events. At Cox analysis, lower MWFS was the only echocardiographic parameter, among structural/functional ones, associated with higher risk of HF/death [hazard ratio (HR) 0.89, 95% confidence interval (CI) 0.84–0.95, Padjusted < 0.001]. The risk of HF/death related to clinical data and NT-proBNP (baseline model) was reclassified by echocardiography only when MWFS was included into the model (baseline C-statistics 0.761; adding conventional structural/functional echocardiographic data 0.776, P = 0.09; adding MWFS 0.791, P = 0.007). Compared to subjects with normal LVEF and MWFS, only subjects with combined systolic dysfunction (11% of the population) were at higher risk (P = 0.001 for both abnormal; P > 0.24 for either LVEF or MWFS abnormal). Conclusion  DAVID-Berg data suggest to include MWFS assessment in clinical practice, a simple and reliable echocardiographic parameter able to improve risk stratification in subjects at high risk for HF.

Background: Left ventricular dysfunction (LVD) can occur immediately after mitral valve repair (MVr) for degenerative mitral regurgitation (DMR) in some patients with normal preoperative left ventricular ejection fraction (LVEF). This study investigated whether forward LVEF, calculated as left ventricular outflow tract stroke volume divided by left ventricular end-diastolic volume, could predict LVD immediately after MVr in patients with DMR and normal LVEF. Methods: Echocardiographic and clinical data were retrospectively evaluated in 234 patients with DMR ≥ moderate and preoperative LVEF ≥ 60%. LVD and non-LVD were defined as LVEF < 50% and ≥50%, respectively, as measured by echocardiography after MVr and before discharge. Results: Of the 234 patients, 52 (22.2%) developed LVD at median three days (interquartile range: 3–4 days). Preoperative forward LVEF in the LVD and non-LVD groups were 24.0% (18.9–29.5%) and 33.2% (26.4–39.4%), respectively (p < 0.001). Receiver operating characteristic (ROC) analyses showed that forward LVEF was predictive of LVD, with an area under the ROC curve of 0.79 (95% confidence interval: 0.73–0.86), and an optimal cut-off was 31.8% (sensitivity: 88.5%, specificity: 58.2%, positive predictive value: 37.7%, and negative predictive value: 94.6%). Preoperative forward LVEF significantly correlated with preoperative mitral regurgitant volume (correlation coefficient [CC] = −0.86, p < 0.001) and regurgitant fraction (CC = −0.98, p < 0.001), but not with preoperative LVEF (CC = 0.112, p = 0.088). Conclusion: Preoperative forward LVEF could be useful in predicting postoperative LVD immediately after MVr in patients with DMR and normal LVEF, with an optimal cut-off of 31.8%.

Abstract Funding Acknowledgements Type of funding sources: None. Background Plasma levels and N-terminal pro B-type natriuretic peptide (NT- proBNP), a cardiac neurohormone released in response to increased ventricular stress, represent an important predictor of clinical outcomes and left ventricular (LV) dysfunction; Although, its diagnostic and prognostic role in patients with acute myocarditis is not completely established; Our aim was to evaluate the relationship of BNP levels and LV ejection fraction (LVEF) in patients with myocarditis; Methods Data from patients (pts) discharged with the diagnosis of myocarditis, from 2008 and 2018 were retrospectively analysed. Results 62 pts were included. Mean age was 39.7 17 years and 89% (58 patients) were men. Plasma levels of NT-proBNP measured at admission ranged from 24 to 3110 pg/mL (median 514, IQR 947), and exceeded upper normal levels in 51 pts (82%). This values positively correlated with C- reactive protein (CRP) (p= 0.005, r = 0.36), leucocytes (p = 0.03, r= 0.37) and neutrophil-to-lymphocyte ratio (p= 0.05, r= 0.35), but not with left ventricular ejection fraction (LVEF) (p= 0.829). Higher levels of BNP were associated with higher troponin peak levels but not with increased mortality (p = 0.811), need of inotropic support (p= 0.059) or arrhythmic events (p= 0.130). Inflammatory parameters were significantly increased when BNP&gt; 514 pg/mL vs BNP &lt;514 pg/mL (CRP 7.2 vs 4 mg/dL, p= 0.008). This relationship was maintained at BNP &gt; 900. LVEF was comparable in both groups (p = 0.938); In this population, the magnitude of recovery of the NT- proBNP values (variation between NT-proBNP at admission and discharge) strongly correlated with the magnitude of the inflammatory markers at admission (all p &lt; 0,005) Conclusion In patients with acute myocarditis, there is a significant relationship between NT-proBNP levels and inflammation (as measured by leucocytes, NLR or CRP), but not with LVEF; Despite the limitation of a small sample size, we could hypothesize that NTproBNP in this subset of patients appears to be regulated not only by hemodynamic changes but also by the underlying systemic inflammatory process and, therefore, it interpretation should take that into account;

Introduction: Preterm (PT) birth is associated with increased risk of cardiovascular diseases (CVD) and heart failure. We previously reported left ventricular (LV) mitochondrial dysfunction in a rat model mimicking the deleterious conditions associated with PT birth. Whether mitochondrial function is altered in humans born PT and associated with LV function changes is unknown. We aimed to determine if serum humanin levels, a mitochondrial-derived peptide with cytoprotective effects, are altered in humans born PT and are associated with impaired myocardial function. Methods: Data were obtained from 55 young adults born PT (<30 weeks of gestational age, GA) compared to 54 full-term (T) controls of the same age. Serum humanin levels were determined by ELISA and LV ejection fraction (LVEF) by echocardiography. Results are shown as median (interquartile range) and comparisons between groups were performed using non-parametric tests. Results: Individuals were evaluated at 23.3 (21.4, 25.3) years, and age and sex distribution were similar between groups. Median GA was 27.5 (26.2, 28.4) weeks in the PT group. Humanin levels (pg/ml) were 132.9 (105.1, 189.3) and 161.1 (123.6, 252) in the PT and the T groups, respectively (p=0.0414). LVEF was within the normal range and similar between groups. Lower LVEF was associated with lower humanin levels (p<0.001), and this association was observed both in the term (p=0.002) and the preterm (p=0.047) groups. Conclusions: Serum humanin levels are lower in adult born PT. Since lower humanin levels are also associated with lower LVEF, our results suggest that mitochondrial alterations could play a role in the long-term adverse cardiovascular consequences of PT birth. Humanin analogs improve LV function in experimental models. Our results pave the way for future studies exploring humanin as a therapeutic avenue for the prevention and treatment of CVD in individuals born PT.

Heart failure (HF) and atrial fibrillation (AF) are the most common cardiovascular conditions in clinical practice and frequently coexist. The number of patients with HF and AF is increasing every year.Aim. To analyze the effect of clinical course and management of HF and AF on the outcomes.Material and methods. The data of 1,003 patients from the first Russian register of patients with HF and AF (RIF-CHF) were analyzed. The endpoints included hospitalization due to decompensated HF, cardiovascular mortality, thromboembolic events, and major bleeding. Predictors of unfavorable outcomes were analyzed separately for patients with HF with preserved ejection fraction (AF+HFpEF), mid-range ejection fraction (AF+HFmrEF), and reduced ejection fraction (AF+HFrEF).Results. Among all patients with HF, 39% had HFpEF, 15% — HFmrEF, and 46% — HFrEF. A total of 57,2% of patients were rehospitalized due to decompensated HF within one year. Hospitalization risk was the highest for HFmrEF patients (66%, p=0,017). Reduced ejection fraction was associated with the increased risk of cardiovascular mortality (15,5% vs 5,4% in other groups, p<0,001) but not ischemic stroke (2,4% vs 3%, p=0,776). Patients with HFpEF had lower risk to achieve the composite endpoint (stroke+MI+cardiovascular death) as compared to patients with HFmrEF and HFrEF (12,7% vs 22% and 25,5%, p<0,001). Regression logistic analysis revealed that factors such as demographic characteristics, disease severity, and selected therapy had different effects on the risk of unfavorable outcomes depending on ejection fraction group.Conclusion. Each group of patients with different ejection fractions is characterized by its own pattern of factors associated with unfavorable outcomes. The demographic and clinical characteristics of patients with mid-range ejection fraction demonstrate that these patients need to be studied as a separate cohort.

The aim of the study was to investigate the features of clinically suspected myocarditis complicated by the left ventricular systolic dysfunction development. 93 patients with clinically suspected myocarditis were examined. The average age was 36.63 ± 1.15 years. In 43.01 % of patients the disease was accompanied by a decrease in left ventricular systolic function. In the group of patients with left ventricular systolic dysfunction in comparison with those with preserved left ventricular ejection fraction, a significantly lower proportion of men (75 % versus 81 %, respectively, χ2 = 9.3, p < 0,01) and a higher average group age (40.7 ± 1.87 versus 33.6 ± 1.3 years, respectively, p <  0,01) were revealed. The course of the disease in patients with left ventricular systolic dysfunction was characterized by a more frequent development of rhythm disturbances (65 % versus 43.3 %, respectively, χ2  = 4.3, p  < 0,05) and a higher heart rate at admission (94.5 (75‒100) and 85 (70‒89) beats per minute, respectively, p = 0.006). The structural and functional state of the heart according to echocardiography in patients with a reduced left ventricular ejection fraction versus comparison group was characterized by larger heart chambers sizes, more pronounced violations of local left ventricular contractility, more frequent involvement of the right ventricle in the pathological process (56.3  % versus 22.2  %, respectively, χ2   =  6.4, p  < 0,05).
