AbstractNeonatal acute myocardial infarction is a rare event that carries a high mortality rate. We describe the cases of two newborns who survived acute myocardial infarction and discuss the management. The first neonate was born with severe asphyxia and left ventricular myocardial infarction with ventricular tachycardia. In this patient, systemic flow was maintained by right-to-left shunting through the patent ductus arteriosus. The second neonate presented with a haematocrit of 80% and an inferolateral myocardial infarction. Intensive treatment of low cardiac output syndrome led to survival of both high-risk neonates. In the follow-up, at 48 and 4 months, respectively, ventricular function recovered in both patients.

Introduction: Patent ductus arteriosus (PDA) is often recognized and treated with percutaneous closure in adults. However, the impact on cardiac reverse remodeling following PDA closure in adults is not clear. We performed a meta-analysis to characterize the extent of cardiac remodeling following percutaneous PDA closure in adults. Methods: MEDLINE and EMBASE were systematically searched for original studies that reported echocardiographic variables at baseline, immediately post-procedure (within 24 hours), and at follow-up (>1 month) in adults undergoing percutaneous PDA closure. Additionally, we included echocardiographic data from a cohort of patients >18 years of age that underwent percutaneous PDA closure between 01/2015 and 12/2019 at our centre. For parameters with sufficient data for pooling, weighted averages were calculated, and pooled differences were presented as weighted mean differences. Heterogeneity was assessed using the I 2 statistic. Results: After screening 278 abstracts, 5 studies were identified. When combined with our own cohort of 13 patients, our meta-analysis encompassed 244 patients. The weighted mean age of all patients was 33 years with all studies predominantly comprised of female patients and the median follow-up was 12 months (ranging from 1 month- 5 years across the studies). When compared to baseline, left ventricular ejection fraction (LVEF) decreased significantly immediately post-procedure and all parameters significantly decreased at follow-up (Table 1). Conclusions: As demonstrated by the decreases in the left ventricular and left atrial sizes, reverse remodeling was observed in adults who underwent percutaneous PDA closure. The significantly lower LVEF immediately post-procedure could reflect withdrawal of chronic volume overload or increased afterload. The clinical significance of the statistically significant lower LVEF on follow-up testing is unclear and requires further evaluation.

Abstract Aim Current guidelines recommend the use of vitamin K antagonist (VKA) for up to 3–6 months for treatment of left ventricular (LV) thrombus post-acute myocardial infarction (AMI). However, based on evidence supporting non-inferiority of novel oral anticoagulants (NOAC) compared to VKA for other indications such as deep vein thrombosis, pulmonary embolism (PE), and thromboembolic prevention in atrial fibrillation, NOACs are being increasingly used off licence for the treatment of LV thrombus post-AMI. In this study, we investigated the safety and effect of NOACs compared to VKA on LV thrombus resolution in patients presenting with AMI. Methods and results This was an observational study of 2328 consecutive patients undergoing coronary angiography ± percutaneous coronary intervention (PCI) for AMI between May 2015 and December 2018, at a UK cardiac centre. Patients’ details were collected from the hospital electronic database. The primary endpoint was rate of LV thrombus resolution with bleeding rates a secondary outcome. Left ventricular thrombus was diagnosed in 101 (4.3%) patients. Sixty patients (59.4%) were started on VKA and 41 patients (40.6%) on NOAC therapy (rivaroxaban: 58.5%, apixaban: 36.5%, and edoxaban: 5.0%). Both groups were well matched in terms of baseline characteristics including age, previous cardiac history (previous myocardial infarction, PCI, coronary artery bypass grafting), and cardiovascular risk factors (hypertension, diabetes, hypercholesterolaemia). Over the follow-up period (median 2.2 years), overall rates of LV thrombus resolution were 86.1%. There was greater and earlier LV thrombus resolution in the NOAC group compared to patients treated with warfarin (82% vs. 64.4%, P = 0.0018, at 1 year), which persisted after adjusting for baseline variables (odds ratio 1.8, 95% confidence interval 1.2–2.9). Major bleeding events during the follow-up period were lower in the NOAC group, compared with VKA group (0% vs. 6.7%, P = 0.030) with no difference in rates of systemic thromboembolism (5% vs. 2.4%, P = 0.388). Conclusion These data suggest improved thrombus resolution in post-acute coronary syndrome (ACS) LV thrombosis in patients treated with NOACs compared to VKAs. This improvement in thrombus resolution was accompanied with a better safety profile for NOAC patients vs. VKA-treated patients. Thus, provides data to support a randomized trial to answer this question.

Abstract Background and purpose Previous studies and meta-analyses of perioperative levosimendan to improve the outcomes of patients with low cardiac output syndrome (LCOS) undergoing cardiac surgery have given controversial results and the optimal time of infusion of levosimendan remains uncertain. We thus aimed to elucidate the risk/benefit ratio of preoperative levosimendan in a meta-analysis of randomized controlled trials (RCTs). Methods Online databases were searched for RCTs comparing preoperative levosimendan to placebo in patients with LCOS undergoing cardiac surgery until February 2019. Data from retrieved studies were abstracted and analyzed in a comprehensive meta-analysis. Primary outcome was all-cause mortality. Secondary outcomes included myocardial infarction, renal failure/replacement therapy, need for inotropic therapy, need for left ventricular assist devices, ventricular arrhythmia and arterial hypotension. Results As a result of the online database search, six eligible RCTs with 1,326 patients were included in the meta-analysis. Preoperative levosimendan showed a significant reduction in all-cause mortality (odds ratio (OR) 0.49, 95% confidence interval (CI) 0.29–0.83; p<0.01), renal failure/replacement therapy (OR 0.48, CI 0.29–0.80; p<0.01) and need for inotropic therapy (OR 0.24, CI 0.06–0.95; p=0.04) compared to placebo. There were no significant differences in levosimendan vs. placebo concerning the rates of myocardial infarction (OR 0.61, p=0.38), need for left ventricular assist devices (OR 0.38, p=0.1), ventricular arrhythmia (OR 0.7, p=0.33), and arterial hypotension (OR 1.28, p=0.07). Conclusions Preoperative administration of levosimendan may improve survival in patients with low cardiac output syndrome undergoing cardiac surgery. It reduces need for inotropic medical support and renal failure/replace-ment therapy compared to placebo.
