Show moreObjectivePatients with a systemic right ventricle (sRV) in the context of transposition of the great arteries (TGA) after atrial switch or congenitally corrected TGA (ccTGA) are prone to sRV dysfunction. Pharmacological options for sRV failure remain poorly defined. This study aims to investigate the tolerability and effects of sacubitril/valsartan on sRV failure in adult patients with sRV. MethodsIn this two-centre, prospective cohort study, all consecutive adult patients with symptomatic heart failure and at least moderately reduced sRV systolic function were initiated on sacubitril/valsartan and underwent structured follow-up. ResultsData of 40 patients were included (40% female, 30% ccTGA, median age 48 (44-53) years). Five patients discontinued therapy during titration. Median follow-up was 24 (12-36) months. The maximal dose was tolerated by 49% of patients. No episodes of hyperkalaemia or renal function decline occurred. Six-minute walking distance increased significantly after 6 months of treatment (569 +/- 16 to 597 +/- 16 m, p=0.016). Serum N-terminal-prohormone brain natriuretic peptide (NT-proBNP) levels decreased significantly after 3 months (567 (374-1134) to 404 (226-633) ng/L, p<0.001). Small, yet consistent echocardiographic improvements in sRV function were observed after 6 months (sRV global longitudinal strain: -11.1 +/- 0.5% to -12.6 +/- 0.7%, p<0.001, and fractional area change: 20% (16%-24%) to 26% (19%-30%), p<0.001). The linear mixed-effects model illustrated that after first follow-up moment, no time effect was present for the parameters. ConclusionsTreatment with sacubitril/valsartan was associated with a low rate of adverse effects in this adult sRV cohort. Persisting improvement in 6-minute walking test distance, NT-proBNP levels and echocardiographic parameters of sRV function was observed in an on-treatment analysis and showed no differential response based on sex or anatomy.

Show moreIMPORTANCE The temporal trend in adverse events regarding stroke prevention for nonvalvular atrial fibrillation (NVAF) in the direct oral anticoagulant (DOAC) era was rarely investigated comprehensively, especially taking into account potential changes in patient characteristics and anticoagulation treatment.OBJECTIVE To investigate time trends in patient characteristics, anticoagulation treatment, and prognosis of patients with incident NVAF in the Netherlands.DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study assessed patients with incident NVAF initially recognized within a hospitalization between 2014 and 2018, using data from Statistics Netherlands. Participants were followed-up for 1 year from the hospital admission at which the incident NVAF diagnosis was made or until death, whichever occurred first. Data were analyzed from January 15, 2021, to March 8, 2023.EXPOSURE Calendar year of the incident NVAF diagnosis, according to which the participants were categorized into 5 cohorts.MAIN OUTCOMES AND MEASURES Outcomes of interest were baseline patient characteristics, anticoagulation treatment, and occurrence of ischemic stroke or major bleeding within the 1-year follow-up after incident NVAF.RESULTS Between 2014 and 2018, 301 301 patients (mean [SD] age, 74.2 [11.9] years; 169 748 [56.3%] male patients) experienced incident NVAF in the Netherlands, each of whom was categorized into 1 of 5 cohorts by calendar year. Baseline patient characteristics were broadly the same between cohorts with a mean (SD) CHA2DS2-VASc (congestive heart failure, hypertension, age >= 75 years [doubled], diabetes, stroke [doubled], vascular disease, age 65 to 74 years, and sex category [female]) score of 2.9 (1.7). The median (IQR) proportion of days covered by OACs (ie, vitamin K antagonists or DOACs) within the 1-year follow-up increased from 56.99% (0%-86.30%) to 75.62%(0%-94.52%), and DOACs increased from 5102 patients (13.5%) to 32 314 patients (72.0%) among those who received OACs, gradually replacing VKAs as the first choice of OACs. Over the course of the study, there were statistically significant decreases in the 1-year cumulative incidence of ischemic stroke (from 1.63%[95% CI, 1.52%-1.73%] to 1.39%[95% CI, 1.30%-1.48%) and major bleeding (from 2.50% [95% CI, 2.37%-2.63%] to 2.07%[95% CI, 1.96%-2.19%]), and the association was consistent after adjusting for baseline patient characteristics and excluding those with preexisting chronic anticoagulation.CONCLUSIONS AND RELEVANCE This cohort study of patients with incident NVAF diagnosed between 2014 and 2018 in the Netherlands found similar baseline characteristics, increased OAC use with DOACs being favored over time, and improved 1-year prognosis. Comorbidity burden, potential underuse of anticoagulation medications, and specific subgroups of patients with NVAF remain directions for future investigations and further improvement. Show less

Show moreThis clinical consensus statement reviews the use of inotropic support in patients with advanced heart failure. The current guidelines only support use of inotropes in the setting of acute decompensated heart failure with evidence of organ malperfusion or shock. However, inotropic support may be reasonable in other patients with advanced heart failure without acute severe decompensation. The clinical evidence supporting use of inotropes in these situations is reviewed. Particularly, patients with persistent congestion, systemic hypoperfusion, or advanced heart failure with need for palliation, and specific situations relevant to implantation of left ventricular assist devices or heart transplantation are discussed. Traditional and novel drugs with inotropic effects are discussed and use of guideline-directed therapy during inotropic support is reviewed. Finally, home inotropic therapy is described, and palliative care and end-of-life aspects are reviewed in relation to management of ongoing inotropic support (including guidance for maintenance and weaning of chronic inotropic therapy support).

Show moreBackground: Left ventricular assist device (LVAD) therapy is an established treatment for advanced heart failure with reduced ejection fraction. We evaluated the characteristics and clinical outcomes of patients implanted with an LVAD in the Netherlands. Methods: Patients implanted with an LVAD in the Netherlands between 2016 and 2020 were included in the analysis. Baseline characteristics entered into this registry, as well as clinical outcomes (death on device, heart transplantation) and major adverse events (device dysfunction, major bleeding, major infection and cerebrovascular event), were evaluated. Results: A total of 430 patients were implanted with an LVAD; mean age was 55 +/- 13 years and 27% were female. The initial device strategy was bridge to transplant (BTT) in 50%, destination therapy (DT) in 29% and bridge to decision (BTD) in the remaining 21%. After a follow-up of 17 months, 97 (23%) patients had died during active LVAD support. Survival was 83% at 1 year, 76% at 2 years and 54% at 5 years. Patients implanted with an LVAD as a BTT had better outcomes compared with DT at all time points (1 year 86% vs 72%, 2 years 83% vs 59% and 5 years 58% vs 33%). Major adverse events were frequently observed, most often major infection, major bleeding and cerebrovascular events (0.84, 0.33 and 0.09 per patient-year at risk, respectively) and were similar across device strategies. Patients supported with HeartMate 3 had a lower incidence of major adverse events. Conclusions: Long-term survival on durable LVAD support in the Netherlands is over 50% after 5 years. Major adverse events, especially infection and bleeding, are still frequently observed, but decreasing with the contemporary use of HeartMate 3 LVAD. Show less

Show moreAims In symptomatic patients with heart failure and reduced ejection fraction (HFrEF), recent international guidelines recommend initiating four major therapeutic classes rather than sequential initiation. It remains unclear how this change in guidelines is perceived by practicing cardiologists versus heart failure (HF) specialists.Methods and results An independent academic web-based survey was designed by a group of HF specialists and posted by email and through various social networks to a broad community of cardiologists worldwide 1 year after the publication of the latest European HF guidelines. Overall, 615 cardiologists (38 [32-47] years old, 63% male) completed the survey, of which 58% were working in a university hospital and 26% were HF specialists. The threshold to define HFrEF was <= 40% for 61% of the physicians. Preferred drug prescription for the sequential approach was angiotensin-converting enzyme inhibitors or angiotensin receptor-neprilysin inhibitors first (74%), beta-blockers second (55%), mineralocorticoid receptor antagonists third (52%), and sodium-glucose cotransporter 2 inhibitors (53%) fourth. Eighty-four percent of participants felt that starting all four classes was feasible within the initial hospitalization, and 58% felt that titration is less important than introducing a new class. Age, status in training, and specialization in HF field were the principal characteristics that significantly impacted the answers.Conclusion In a broad international cardiology community, the 'historical approach' to HFrEF therapies remains the preferred sequencing approach. However, accelerated introduction and uptitration are also major treatment goals. Strategy trials in treatment guidance are needed to further change practices.[GRAPHICS]. Show less

Show moreNeo(adjuvant) systemic treatment regimens containing anthracyclines such as doxorubicin cause a significant risk of heart failure. These regimens are one of the corner stones of osteosarcoma treatment, and therefore several guidelines are in place to steer cardiotoxicity monitoring through baseline risk stratification and cardiac surveillance during and after completion of cancer therapy. Importantly, baseline risk stratification modules are dependent on age, prior cardiovascular disease and cardiovascular risk factors. Because the majority of osteosarcoma patients are below 30 years of age these criteria rarely apply and most patients are assigned to low or medium risk categories, whereas cardiovascular complications have profound impact on morbidity and mortality in this young population. Therefore, cardiac surveillance is very important in this group for timely detection of cardiotoxicity. Moreover, when severe cardiotoxicity that requires advanced heart failure treatment occurs, a cancer diagnosis has significant implications on treatment options, i.e. mechanical circulatory support and heart transplantation. These challenges are presented in this case of a patient without clinical risk factors admitted with cardiogenic shock requiring advanced heart failure treatment within 1 month after completion of doxorubicin containing chemotherapy for the treatment of high grade osteosarcoma.

Show moreLeft ventricular assist device (LVAD) implantation as destination therapy (DT) is a valuable treatment option in patients with end-stage heart failure ineligible for heart transplant. However, this therapy can be complicated by life-threatening pump thrombosis (PT). This case series reports our single-center experience with a structured systemic thrombolysis protocol in case of PT. Consecutive patients undergoing DT LVAD (HVAD, Medtronic, Framingham, MA) implantation between 2010 and April 2021 at our institution were reviewed and those with PT identified. Clinical, laboratory and LVAD specific data were collected and analyzed retrospectively. All patients with PT were treated with systemic thrombolysis according to a structured bedside protocol. Treatment was defined successful if a patient was alive at 30 days follow-up and free of recurrent PT, stroke or device exchange. Fourteen out of 94 patients experienced a PT after LVAD implantation (11%). Systemic thrombolysis was successful in 10 of 14 patients (71%) at 30 days. Two patients died within 30 days due to a hemothorax and multi-organ failure. In three patients treatment was complicated by a major bleeding; twice a hemothorax (one fatal) and one right calf bleeding. No intracerebral hemorrhage was observed. Three patients experienced a thrombotic complication within 30 days; all recurrent PT. Eleven of the 14 DT patients were discharged home after a limited hospital stay after thrombolysis (average of 11 days). In conclusion, systemic thrombolysis may be a reasonable option for life-threatening PT in this vulnerable DT group in whom device exchange is often impossible due to comorbidity. Show less

Show moreOBJECTIVES: The objective was to analyse associations between obesity and outcomes after left ventricular assist device (LVAD) implantation.METHODS: A retrospective analysis of the EUROMACS Registry was performed. Adult patients undergoing primary implantation of a continuous-flow LVAD between 2006 and 2019 were included (Medtronic HeartWare((R)) HVAD((R)), Abbott HeartMate II (R), Abbott HeartMate 3 (TM)). Patients were classified into 4 different groups according to body mass index at the time of surgery (body mass index <20 kg/m(2): n = 254; 20-24.9 kg/m(2): n = 1281; 25-29.9 kg/m(2): n = 1238; >= 30 kg/m(2): n = 691).RESULTS: The study cohort was comprised of 3464 patients. Multivariable Cox proportional cause-specific hazards regression analysis demonstrated that obesity (body mass index >= 30 kg/m(2)) was independently associated with significantly increased risk of mortality (body mass index >= 30 vs 20-24.9 kg/m(2): hazard ratio 1.36, 95% confidence interval 1.18-1.57, overall P < 0.001). Moreover, obesity was associated with significantly increased risk of infection and driveline infection. The probability to undergo heart transplantation was significantly decreased in obese patients (body mass index >= 30 vs 20-24.9 kg/m(2): hazard ratio 0.59, 95% confidence interval 0.48-0.74, overall P < 0.001).CONCLUSIONS: Obesity at the time of LVAD implantation is associated with significantly higher mortality and increased risk of infection as well as driveline infection. The probability to undergo heart transplantation is significantly decreased. These aspects should be considered when devising a treatment strategy before surgery. Show less

Show morePump thrombosis is a devastating complication after left ventricular assist device implantation. This study aims to elucidate the relation between left ventricular assist device implantation angle and risk of pump thrombosis. Between November 2010 and March 2020, 53 left ventricular assist device-patients underwent a computed tomography scan. Using a 3-dimensional multiplanar reformation the left ventricular axis was reconstructed to measure the implantation angle of the inflow cannula. All patients were retrospectively analyzed for the occurrence of pump thrombosis. In 10 (91%) patients with a pump thrombosis, the implantation angle was towards the lateral wall of the left ventricle. In only 20 patients (49%) of the patients without a pump thrombosis the inflow cannula pointed towards the lateral wall of the left ventricle. The mean angle in patients with a pump thrombosis was 10.1 +/- 11.9 degrees towards the lateral wall of the left ventricle compared to 4.1 +/- 19.9 degrees towards the septum in non-pump thrombosis patients (P = 0.005). There was a trend towards a significant difference in time to first pump thrombosis between patients with a lateral or septal deviated left ventricular assist device (hazard ratio of 0.15, P = 0.07). This study demonstrates that left ventricular assist device implantation angle is associated with pump thrombosis. Almost all patients in whom a pump thrombosis occurred during follow-up had a left ventricular assist device implanted with the inflow-cannula pointing towards the lateral wall of the left ventricle.

Show moreIn congenitally corrected transposition of the great arteries, the morphological right ventricle supports the systemic circulation. This chronic exposure to pressure overload ultimately leads to systemic right ventricular (sRV) dysfunction and heart failure. Pharmacological options for the treatment of sRV failure are poorly defined and no solid recommendations are made in the most recent guidelines. Sodium-glucose cotransporter 2 (SGLT-2) inhibitors are a new class of antihyperglycaemic drugs that have been demonstrated to significantly reduce the risk of worsening heart failure and death from cardiovascular causes in patients with chronic heart failure with reduced left ventricular ejection fraction, yet no data are available in sRV patients. We report on the treatment and clinical follow-up of a patient with advanced heart failure and poor sRV function in the context of congenitally corrected transposition of the great arteries, who did not tolerate sacubitril/valsartan and had a high burden of heart-failure-related hospitalizations. Treatment with dapagliflozin was well tolerated and resulted in (small) subjective and objective functional and echocardiographic improvement and a reduction in heart-failure-related hospitalizations.

Show moreObjective Pharmacological options for patients with a failing systemic right ventricle (RV) in the context of transposition of the great arteries (TGA) after atrial switch or congenitally corrected TGA (ccTGA) are not well defined. This study aims to investigate the feasibility and effects of sacubitril/valsartan treatment in a single-centre cohort of patients. Methods Data on all consecutive adult patients (n=20, mean age 46 years, 50% women) with a failing systemic RV in a biventricular circulation treated with sacubitril/valsartan in our centre are reported. Patients with a systemic RV ejection fraction of <= 35% who were symptomatic despite treatment with beta-blocker and ACE-inhibitor/angiotensin II receptor-blockers were started on sacubitril/valsartan. This cohort underwent structural follow-up including echocardiography, exercise testing, laboratory investigations and quality of life (QOL) assessment. Results Six-month follow-up data were available in 18 out of 20 patients, including 12 (67%) patients with TGA after atrial switch and 6 (33%) patients with ccTGA. N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) decreased significantly (950-358 ng/L, p<0.001). Echocardiographic systemic RV fractional area change and global longitudinal strain showed small improvements (19%-22%, p<0.001 and -11% to -13%, p=0.014, respectively). The 6 min walking distance improved significantly from an average of 564 to 600 m (p=0.011). The QOL domains of cognitive function, sleep and vitality improved (p=0.015, p=0.007 and p=0.037, respectively). Conclusions We describe the first patient cohort with systemic RV failure treated with sacubitril/valsartan. Treatment appears feasible with improvements in NT-pro-BNP and echocardiographic function. Our positive results show the potential of sacubitril/valsartan for this patient population. Show less

Show moreBackground Cardiac implanted electronic devices (CIED) have significantly improved the survival and quality of life in heart failure patients. Although implantable cardioverter-defibrillators (ICD) and cardiac resynchronization therapy (CRT) have a major role in patients with moderate to severe heart failure symptoms, the role of these devices in patients with a left ventricular assist device (LVAD) is not yet well defined. The burden of CIED-related procedures in patients with an LVAD is high. The price of lead malfunctions and pocket complications requires creative approaches to tackle CIED-related issues in this patient population.Case summary Here, we describe the clinical course of a 67-year-old ventricular pacing dependent LVAD patient with an ICD indication based on recurrent monomorphic ventricular tachycardias and a CRT indication due to previous deterioration of (right-sided) heart failure in the absence of biventricular pacing. We were confronted with impending right ventricular lead failure and bilateral venous access problems due to chronic subclavian vein occlusion in a patient with a total of five transvenous leads, therapeutic anticoagulation, and pronounced thoracic collaterals. We sought for a creative solution to be able to deliver effective biventricular fusion pacing with the existing leads from two contralateral pulse generators resulting in biventricular fusion pacing. This provided the solution to deliver effective CRT.Discussion This case illustrates the complexity of care and CIED-related decision-making in pacing dependent LVAD patients, in particularly those with an ICD and CRT indication.

Show moreAims: Major adverse event (MAE) rates during left ventricular assist device (LVAD) therapy in advanced heart failure (HF) patients are high, and impair quality of life and survival. Prediction and risk stratification of MAEs in order to improve patient selection and thereby outcome during LVAD therapy is therefore warranted. Circulating natriuretic peptides (NPs) are strong predictors of MAEs and mortality in chronic HF patients. However, whether NPs can identify patients who are at risk of MAEs and mortality or tend toward myocardial recovery after LVAD implantation is unclear. The aim of this systematic review is to analyze the prognostic value of circulating NP levels before LVAD implantation for all-cause mortality, MAEs and myocardial recovery after LVAD implantation.Methods and Results: Electronic databases were searched for studies analyzing circulating NP in adults with advanced HF before LVAD implantation in relation to mortality, MAEs, or myocardial recovery after LVAD implantation. Twenty-four studies published between 2008 and 2021 were included. Follow-up duration ranged from 48 hours to 5 years. Study sample size ranged from 14 to 15,138 patients. Natriuretic peptide levels were not predictive of all-cause mortality. However, NPs were predictive of right ventricular failure (RVF) and MAEs such as ventricular arrhythmias, moderate or severe aortic regurgitation, and all-cause rehospitalization. No relation between NPs and myocardial recovery was found.Conclusion: This systematic review found that NP levels before LVAD implantation are not predictive of all-cause mortality after LVAD implantation. Thus, NP levels may be of limited value in patient selection for LVAD therapy. However, NPs help in risk stratification of MAEs and may be used to identify patients who are at risk for RVF, ventricular arrhythmias, moderate or severe aortic regurgitation, and all-cause rehospitalization after LVAD implantation.
