Background: Acetazolamide inhibits proximal tubular sodium reabsorption and improved decongestion in the ADVOR (Acetazolamide in Decompensated Heart Failure with Volume Overload) trial. It remains unclear whether the decongestive effects of acetazolamide differ across the spectrum of left ventricular ejection fraction (LVEF). Methods: This is a prespecified analysis of the randomized, double-blind, placebo-controlled ADVOR trial that enrolled 519 patients with acute heart failure (HF), clinical signs of volume overload (eg, edema, pleural effusion, or ascites), NTproBNP (N-terminal pro-B-type natriuretic peptide) >1000 ng/L, or BNP (B-type natriuretic peptide) >250 ng/mL to receive intravenous acetazolamide (500 mg once daily) or placebo in addition to standardized intravenous loop diuretics (twice that of the oral home maintenance dose). Randomization was stratified according to LVEF (≤40% or >40%). The primary end point was successful decongestion, defined as the absence of signs of volume overload within 3 days from randomization without the need for mandatory escalation of decongestive therapy because of poor urine output. Results: Median LVEF was 45% (25th to 75th percentile; 30% to 55%), and 43% had an LVEF ≤40%. Patients with lower LVEF were younger and more likely to be male with a higher prevalence of ischemic heart disease, higher NTproBNP, less atrial fibrillation, and lower estimated glomerular filtration rate. No interaction on the overall beneficial treatment effect of acetazolamide to the primary end point of successful decongestion (OR, 1.77 [95% CI, 1.18-2.63]; P =0.005; all P values for interaction >0.401) was found when LVEF was assessed per randomization stratum (≤40% or >40%), or as HF with reduced ejection fraction, HF with mildly reduced ejection fraction, and HF with preserved ejection fraction, or on a continuous scale. Acetazolamide resulted in improved diuretic response measured by higher cumulative diuresis and natriuresis and shortened length of stay without treatment effect modification by baseline LVEF (all P values for interaction >0.160). Conclusions: When added to treatment with loop diuretics in patients with acute decompensated HF, acetazolamide improves the incidence of successful decongestion and diuretic response, and shortens length of stay without treatment effect modification by baseline LVEF.

Conduction-system involvement in cardiac amyloidosis (CA) is common. The prevalence, clinical correlates and impact on outcome related to ventricular electrical dyssynchrony in CA remain insufficiently elucidated.Data from a prospectively maintained registry of patients with CA diagnosed in the Cleveland Clinic's amyloidosis clinic was used to determine the frequency of electrical dyssynchrony (defined as a QRS130 msec). The relation with the clinical profile and clinical outcome was assessed. To determine the impact of hypertrophy on QRS prolongation, a QRS-matched cohort without CA was used for comparison of cardiac magnetic resonance imaging.A total of 1140 patients with CA (39% AL, 61% TTR) were evaluated, of whom 230 (20%) had electrical dyssynchrony. The type of conduction block was predominantly a right bundle branch block (BBB, 48%) followed by left BBB (35%) and intraventricular conduction delay (17%). Presence of transthyretin amyloidosis (ATTR-CA), older age, male gender, white race, and coronary artery disease were independently (P0.05 for all) associated with electrical dyssynchrony, and patients were more commonly prescribed a mineralocorticoid receptor antagonist. In ATTR-CA, specifically, every increase in ATTR-CA disease stage was associated with a 1.55-fold (1.23--1.95; P0.001) increased odds for electrical dyssynchrony. In a subset of patients with CA who underwent cardiac magnetic resonance imaging (n = 41), left ventricular mass index was unrelated to the QRS duration (r = 0.187; P = 0.283) in CA, in contrast to a non-CA QRS-matched cohort (r = 0.397; P0.001). Patients with electrical dyssynchrony were more symptomatic at initial presentation, as illustrated by a higher New York Heart Association class (P= 0.041). During a median follow-up of 462 days (IQR:138--996 days), a higher proportion of patients with electrical dyssynchrony died from all-cause death (P= 0.037) or developed a permanent pacing indication (3% vs 10.4%; P0.001) during follow-up.Electrical dyssynchrony is common in CA, especially in ATTR-CA, and is associated with worse functional status and clinical outcome. Given the high rate of permanent pacing indications at follow-up, additional studies are necessary to determine the best monitoring and pacing strategies in CA.

Aim Limited information is available about the short- and long-term outcomes in electrical storm (ES)-induced cardiogenic shock (CS) and its predictors. Methods and results This is a retrospective, single-centre cohort study of consecutive patients with ES admitted to the Cardiac Intensive Care Unit between 2015 and 2020. The proportion of ES patients who developed CS was adjudicated, and clinical predictors of in-hospital ventricular arrhythmia (VA)-related mortality and 1-year all-cause mortality were investigated. Of the 214 patients with ES, 33.6% developed CS. Left-ventricular ejection fraction, admission lactate, absence of an implantable cardioverter defibrillator, and admission central venous pressure were independently associated with development of CS (P < 0.03 for all). Based on these variables, a FLIC score was developed (https://riskcalc.org/FLICscore/) to predict ES-induced CS [area under the curve (AUC) = 0.949, with AUC = 0.954 in a validation cohort, both P < 0.001]. Patients who developed CS had a 11.3-fold [95% confidence interval (CI) 2.7–12.8] increased odds for in-hospital VA-related mortality and 9.4-fold (95% CI 4.0–22.4) increased odds for in-hospital all-cause mortality. A FLIC score above 0.62 was associated with a 6.2- and 5.8-fold increased odds for respectively similar endpoints. Patients with ES-induced CS received more treatment modalities to manage the ES (4.5 ± 1.8 vs. 2.3 ± 1.2, P < 0.001) and had longer length of stay [14 (8–27) vs. 8 (5–13), P < 0.001] than patients without CS. Interestingly, if patients with ES-induced CS survived to discharge, their outcomes were similar to those without CS at 1 year. Conclusion Cardiogenic shock in ES is a frequent and potentially life-threatening complication with high short-term mortality. A novel risk score could identify patient at risk, generating a potential for early risk-based interventions.

Myocarditis is a disease caused by inflammation of the heart that can progress to dilated cardiomyopathy, heart failure, and eventually death in many patients. Several etiologies are implicated in the development of myocarditis including autoimmune, drug-induced, infectious, and others. All causes lead to inflammation which causes damage to the myocardium followed by remodeling and fibrosis. This review aims to summarize recent findings in biomarkers for myocarditis and highlight the most promising candidates.Current methods of diagnosing myocarditis, including imaging and endomyocardial biopsy, are invasive, expensive, and often not done early enough to affect progression. Research is being done to find biomarkers of myocarditis that are cost-effective, accurate, and prognostically informative. These biomarkers would allow for earlier screening for myocarditis, as well as earlier treatment, and a better understanding of the disease course for specific patients. Early diagnosis of myocarditis with biomarkers may allow for prompt treatment to improve outcomes in patients.

Aims Acetazolamide inhibits proximal tubular sodium and bicarbonate re-absorption and improved decongestive response in acute heart failure in the ADVOR trial. It is unknown whether bicarbonate levels alter the decongestive response to acetazolamide. Methods and results This is a sub-analysis of the randomized, double-blind, placebo-controlled ADVOR trial that randomized 519 patients with acute heart failure and volume overload in a 1:1 ratio to intravenous acetazolamide (500 mg/day) or matching placebo on top of standardized intravenous loop diuretics (dose equivalent of twice oral maintenance dose). The primary endpoint was complete decongestion after 3 days of treatment (morning of day 4). Impact of baseline HCO3 levels on the treatment effect of acetazolamide was assessed. : Of the 519 enrolled patients, 516 (99.4%) had a baseline HCO3 measurement. Continuous HCO3 modelling illustrated a higher proportional treatment effect for acetazolamide if baseline HCO3 ≥ 27 mmol/l. A total of 234 (45%) had a baseline HCO3 ≥ 27 mmol/l. Randomization towards acetazolamide improved decongestive response over the entire range of baseline HCO3− levels (P = 0.004); however, patients with elevated baseline HCO3 exhibited a significant higher response to acetazolamide [primary endpoint: no vs. elevated HCO3; OR 1.37 (0.79–2.37) vs. OR 2.39 (1.35–4.22), P-interaction = 0.065), with higher proportional diuretic and natriuretic response (both P-interaction < 0.001), greater reduction in congestion score on consecutive days (treatment × time by HCO3-interaction Conclusion Acetazolamide improves decongestive response over the entire range of HCO3− levels; however, the treatment response is magnified in patients with baseline or loop diuretic-induced elevated HCO3 (marker of proximal nephron NaHCO3 retention) by specifically counteracting this component of diuretic resistance.

BackgroundIn those with heart failure-related cardiogenic shock, intra-aortic balloon pump may improve hemodynamics and be useful as a bridge to advanced therapies. We explore whether those with cardiac amyloidosis and heart failure-related cardiogenic shock might experience hemodynamic improvement and describe the hemodynamic response after intra-aortic balloon pump.MethodsWe retrospectively identified consecutive patients with a diagnosis of cardiac amyloid, either light-chain or transthyretin, who were admitted to our intensive care unit with heart failure-related cardiogenic shock. Patients were excluded if intra-aortic balloon pump was placed during heart transplant or for shock related to acute myocardial infarction. Invasive hemodynamics before and after intra-aortic balloon pump placement were assessed.ResultsWe identified 23 patients with cardiac amyloid who had an intra-aortic balloon pump placed for heart failure-related cardiogenic shock. One-year survival was 74% and most (65%) were bridged to heart transplant while one was bridged to destination left ventricular assist device. Following intra-aortic balloon pump, mean arterial pressure, cardiac index, and cardiac power index were significantly increased, while mean right atrial pressure, mean pulmonary artery pressure, and pulmonary capillary wedge pressure were all significantly reduced. Smaller left ventricular end diastolic diameter (per cm) was associated with higher likelihood of a cardiac index of < 2.2 L/min/m2following intra-aortic balloon pump (OR 0.16, CI 0.01 – 0.93, P=0.04).ConclusionIntra-aortic balloon pump significantly improved cardiac index while reducing right atrial pressure, mean pulmonary artery pressure, and pulmonary capillary wedge pressure in CA patients with heart failure-related cardiogenic shock.

Aims The aim of this study is to evaluate whether the MADIT-ICD benefit score can predict who benefits most from the addition of implantable cardioverter-defibrillator (ICD) to cardiac resynchronization therapy (CRT) in real-world patients with heart failure with reduced ejection fraction (HFrEF) and to compare this with selection according to a multidisciplinary expert centre approach. Methods and results Consecutive HFrEF patients who received a CRT for a guideline indication at a tertiary care hospital (Ziekenhuis Oost-Limburg, Genk, Belgium) between October 2008 and September 2016, were retrospectively evaluated. The MADIT-ICD benefit groups (low, intermediate, and high) were compared with the current multidisciplinary expert centre approach. Endpoints were (i) sustained ventricular tachycardia (VT) or ventricular fibrillation (VF) and (ii) non-arrhythmic mortality. Of the 475 included patients, 165 (34.7%) were in the lowest, 220 (46.3%) in the intermediate, and 90 (19.0%) in the highest benefit group. After a median follow-up of 34 months, VT/VF occurred in 3 (1.8%) patients in the lowest, 9 (4.1%) in the intermediate, and 13 (14.4%) in the highest benefit group (P < 0.001). Vice versa, non-arrhythmic death occurred in 32 (19.4%) in the lowest, 32 (14.6%) in the intermediate, and 3 (3.3%) in the highest benefit group (P = 0.002). The predictive power for ICD benefit was comparable between expert multidisciplinary judgement and the MADIT-ICD benefit score: Uno’s C-statistic 0.69 vs. 0.69 (P = 0.936) for VT/VF and 0.62 vs. 0.60 (P = 0.790) for non-arrhythmic mortality. Conclusion The MADIT-ICD benefit score can identify who benefits most from CRT-D and is comparable with multidisciplinary judgement in a CRT expert centre.

Ferric carboxymaltose (FCM) improves left ventricular function in heart failure with reduced ejection fraction (HFrEF). Yet, the effect of FCM on right ventricular (RV) function remains insufficiently elucidated.This is a pre-defined analysis of the IRON-CRT trial in which symptomatic HFrEF patients with iron deficiency and reduced left ventricular ejection fraction (LVEF) despite optimal medical therapy and cardiac resynchronization therapy (CRT) underwent 1:1 randomization to FCM or placebo in a double-blind fashion. RV function was measured as the change from baseline to 3-month follow-up in RV fractional area change (FAC), tricuspid annular plane systolic excursion (TAPSE) and pulsed Doppler peak velocity at the RV lateral annulus (RV S'), systolic pulmonary artery pressure (SPAP) and its coupling to the right ventricle (TAPSE/SPAP ratio). The RV contractile reserve was measured as the change in TAPSE during incremental pacing at 70, 90 and 110 bpm. A total of 75 patients underwent randomization and received FCM (n = 37) or placebo (n = 38). At baseline 72.5% had RV dysfunction and 70% had RV dilatation. At 3-month follow-up, patients receiving FCM had a significant improvement in RV FAC (+4.1% [+1.4% - +6.9%] vs. -2.2% [-4.9% - +0.6%] in the placebo group, p = 0.002) and TAPSE (+0.98 mm [+0.28 mm - +1.62 mm] vs. -0.19 mm [-0.85 mm - +0.48 mm] in the placebo group, p = 0.020), but not RV S'. Patients receiving FCM had a numerically lower SPAP (p = 0.073) and significant improvement in TAPSE/SPAP ratio (+0.097 [+0.048 - +0.146] vs. +0.002 [-0.046 - +0.051] in the placebo group, p = 0.008). At baseline both groups had diminished RV contractile reserve during incremental pacing, which was attenuated at 3-month follow-up in the FCM group (p = 0.004). Patients manifesting more RV function improvement were more likely to exhibit higher degrees of LVEF improvement (p 0.05 for all).Treatment with FCM in HFrEF patients results in an improvement in RV function and structure and improves the RV contractile reserve.

Aims Magnesium changes are common in myocardial infarction (MI) complicated with left ventricular systolic dysfunction (LVSD) and/or heart failure (HF). The relation between serum magnesium and clinical outcomes is insufficiently elucidated in this population. Methods and results The EPHESUS trial randomized 6632 patients to either eplerenone or placebo. Hypomagnesemia and hypermagnesemia were defined as a serum magnesium 1.10 mmol/L, respectively. Linear mixed models and time-dependent Cox regression analysis were used to determine the effect of eplerenone on magnesium changes and the prognostic importance of magnesium. The co-primary outcomes were all-cause mortality and a composite of cardiovascular (CV) mortality and CV hospitalization. A total of 5371 patients had a post-baseline magnesium measurement. At baseline, 231 (4.3%) patients had hypomagnesemia and 271 (5.0%) patients had hypermagnesemia. During a median follow-up of 16 months, 682 (13%) developed hypomagnesemia and 512 (9.5%) hypermagnesemia. Eplerenone treatment did not result in a different magnesium level during follow-up (P = 0.14). After covariate adjustment hypo- and hypermagnesemia were not associated with a higher risk of CV events. Magnesium levels did not modulate the effect of a high potassium (>5 mmol/L) or low potassium ( 0.1 for all primary and secondary endpoints). Conclusion In patients with MI complicated by LVSD or HF, magnesium alterations were not associated with clinical outcomes nor did they influence the effect of eplerenone. Serum magnesium did not modulate the effect of potassium changes on clinical outcome or the treatment effect of eplerenone. ClinicalTrials.gov identifier NCT00232180.

BACKGROUND: Little information is available on the prognostic relevance of cardiac hemodynamic cutoffs in cardiac amyloidosis (CA) and its subtypes. METHODS: Consecutive patients diagnose with light chain-CA or transthyretin CA undergoing right heart catheterization were analyzed. Prognostic relevance of classic hemodynamic cutoffs of cardiac index (CI 2 ), pulmonary capillary wedge pressure (>18 mm Hg), right atrial pressure (>8 mm Hg), and mean pulmonary artery pressure (≥25 mm Hg or pulmonary hypertension) with the combined end point of cardiac transplant/left ventricular assist device and death and heart failure admissions separately was assessed. RESULTS: A total of 469 CA patients underwent right heart catheterization (light chain CA=42% and transthyretin CA=52%) of whom 69%, 64%, and 79% had elevated right atrial pressure, pulmonary capillary wedge pressure, and pulmonary hypertension, respectively. The classic hemodynamic cutoffs for right atrial pressure (hazard ratio, 1.26 [0.98–1.62]) and mean pulmonary artery pressure (hazard ratio, 1.28 [0.96–1.71]) did not identify patients at higher risk for adverse outcome; however, cutoffs of 14 mm Hg for right atrial pressure (hazard ratio, 1.59 [1.26–2.00]) and 35 mm Hg for mean pulmonary artery pressure (hazard ratio, 1.30 [1.01–1.66]) performed better to detect worse outcome ( P P CONCLUSIONS: Hemodynamic variables are grossly abnormal in CA, but elevated filling pressures are prognostic at significantly higher threshold values than classic cutoff values. CI is the hemodynamic variable most strongly associated with outcome and functionality in CA.

AIMS: Although acute heart failure (AHF) with volume overload is treated with loop diuretics, their dosing and type of administration are mainly based upon expert opinion. A recent position paper from the Heart Failure Association (HFA) proposed a step-wise pharmacologic diuretic strategy to increase the diuretic response and to achieve rapid decongestion. However, no study has evaluated this protocol prospectively. METHODS AND RESULTS: The Efficacy of a Standardized Diuretic Protocol in Acute Heart Failure (ENACT-HF) study is an international, multicentre, non-randomized, open-label, pragmatic study in AHF patients on chronic loop diuretic therapy, admitted to the hospital for intravenous loop diuretic therapy, aiming to enrol 500 patients. Inclusion criteria are as follows: at least one sign of volume overload (oedema, ascites, or pleural effusion), use=40mg of furosemide or equivalent for >1month, and a BNP>250ng/L or an N-terminal pro-B-type natriuretic peptide>1000pg/L. The study is designed in two sequential phases. During Phase 1, all centres will treat consecutive patients according to the local standard of care. In the Phase 2 of the study, all centres will implement a standardized diuretic protocol in the next cohort of consecutive patients. The protocol is based upon the recently published HFA algorithm on diuretic use and starts with intravenous administration of two times the oral home dose. It includes early assessment of diuretic response with a spot urinary sodium measurement after 2h and urine output after 6h. Diuretics will be tailored further based upon these measurements. The study is powered for its primary endpoint of natriuresis after 1day and will be able to detect a 15% difference with 80% power. Secondary endpoints are natriuresis and diuresis after 2days, change in congestion score, change in weight, in-hospital mortality, and length of hospitalization. CONCLUSIONS: The ENACT-HF study will investigate whether a step-wise diuretic approach, based upon early assessment of urinary sodium and urine output as proposed by the HFA, is feasible and able to improve decongestion in AHF with volume overload.

Numerous patients with a cardiac implantable electronic device are admitted to the cardiac intensive care unit (ICU). When taking care of these patients, it is essential to have basic knowledge of potential device problems and how they could be tackled. This review summarizes common issues with pacemakers, implantable cardioverter-defibrillators, and cardiac resynchronization devices and provides a framework for troubleshooting in the ICU. In addition, specific aspects of intensive care that might interfere with cardiac devices are discussed.

Для большинства эпизодов острой сердечной недостаточности характерно усиление симптомов и признаков застойных явлений с объемной перенагрузкой. Цель терапии у таких пациентов заключается в облегчении застойных явлений путем достижения нормоволемии, главным образом с помощью терапии диуретиками. Однако должное применение диуретиков остается сложным, особенно при ухудшении функции почек, резистентности к диуретикам и нарушениях баланса электролитов. В этом официальном заявлении рассматривается применение диуретиков при застойной сердечной недостаточности. В работе рассматриваются распространенные проблемы, такие как: 1) оценка застойных явлений и клинической нормоволемии; 2) оценка ответа на диуретики/резистентности к диуретикам при лечении острой сердечной недостаточности; 3) подход к поэтапным фармакологическим стратегиям применения диуретиков на основе ответа на диуретики; 4) лечение распространенных нарушений баланса электролитов. Рекомендации приведены в соответствии с доступними руководствами, свидетельствами и экспертными выводами., Для більшості епізодів гострої серцевої недостатності характерне посилення симптомів та ознак застійних явищ з об’ємним перенавантаженням. Мета терапії в таких пацієнтів полягає в полегшенні застійних явищ шляхом досягнення нормоволемії, головним чином за допомогою терапії діуретиками. Проте належне застосування діуретиків залишається складним, особливо при погіршенні функції нирок, резистентності до діуретиків та порушеннях балансу електролітів. У цій офіційній заяві розглядається застосування діуретиків при застійній серцевій недостатності. У роботі розглядаються поширені проблеми, такі як: 1) оцінка застійних явищ та клінічної нормоволемії; 2) оцінка відповіді на діуретики/резистентності до діуретиків при лікуванні гострої серцевої недостатності; 3) підхід до поетапних фармакологічних стратегій застосування діуретиків на основі відповіді на діуретики; 4) лікування поширених порушень балансу електролітів. Рекомендації наведені відповідно до доступних настанов, свідчень та експертних висновків., The vast majority of acute heart failure episodes are characterized by increasing symptoms and signs of congestion with volume overload. The goal of therapy in those patients is the relief of congestion through achieving a state of euvolaemia, mainly through the use of diuretic therapy. The appropriate use of diuretics however remains challenging, especially when worsening renal function, diuretic resistance and electrolyte disturbances occur. This position paper focuses on the use of diuretics in heart failure with congestion. The manuscript addresses frequently encountered challenges, such as (i) evaluation of congestion and clinical euvolaemia, (ii) assessment of diuretic response/resistance in the treatment of acute heart failure, (iii) an approach towards stepped pharmacologic diuretic strategies, based upon diuretic response, and (iv) management of common electrolyte disturbances. Recommendations are made in line with available guidelines, evidence and expert opinion.

Aims Iron deficiency is common in heart failure with reduced ejection fraction (HFrEF) and negatively affects cardiac function and structure. The study the effect of ferric carboxymaltose (FCM) on cardiac reverse remodelling and contractile status in HFrEF. Methods and results Symptomatic HFrEF patients with iron deficiency and a persistently reduced left ventricular ejection fraction (LVEF Conclusions Treatment with FCM in HFrEF patients with iron deficiency and persistently reduced LVEF after CRT results in an improvement of cardiac function measured by LVEF, LVESV, and cardiac force–frequency relationship.

Contemporary data on left ventricular function (LVF) recovery in patients with left ventricular dysfunction after ST-elevation myocardial infarction (STEMI) are scarce and to date, no comparison has been made with patients with a baseline normal LVF. This study examined predictors of LVF recovery and its relation to outcomes in STEMI. Patients presenting with STEMI between January 2010 and December 2016 were categorized in three groups after 3 months according to left ventricular ejection fraction (EF): (i) baseline normal LVF (EF ≥ 50% at baseline); (ii) recovered LVF (EF

Aim: Intrinsic renal sodium avidity (IRSA) is a hallmark feature of acute heart failure (AHF) and can be measured by evaluating the urinary sodium (UNa) concentration. The aim of this study is to assess the role of measuring IRSA through a random Una-sample and its association with decongestive response. Methods and results: A post-hoc analysis of the ROSE-AHF trial was performed in all patients with a random UNa spot sample before randomization (n = 339/360). Patients were categorized according to tertiles of UNa as high (range 19–40 mmol/L), intermediate (range 41–68 mmol/L), or low (range 69–139 mmol/L) IRSA. Linear mixed effect models and ANCOVA were used to assess the relation with decongestive effectiveness measured by: (i) weight change, (ii) visual analogue scale (VAS) improvement, (iii) N-terminal pro-B-type natriuretic peptide (NT-proBNP) change, (iv) natriuretic response (UNa in mmol/L), (v) 72 h natriuresis (mmol), (vi) oedema resolution, and (vii) length of stay. High IRSA patients had less improvement in decongestive metrics, including weight loss (p = 0.028), VAS improvement, NT-proBNP decrease, natriuretic response (p-time interaction 24 h, resulted in an increase in natriuretic response in the high IRSA group, however cumulative natriuresis still remained lower at 72 h (p < 0.001). Longitudinal UNa profiling of patients with low IRSA showed physiologic breaking in the UNa pattern, associated with attaining decongestion and slight increase in creatinine and cystatin C, forming a potential signal of complete decongestion. Conclusions: A simple random UNa sample at the time of AHF, gives insight into IRSA which is consistently associated with decongestive effectiveness across multiple metrics, offering an opportunity for early AHF care improvement.

This review article critically assesses two recent books on the famous city plans of Jacob van Deventer, the Stedenatlas Jacob van Deventer by Reinout Rutte en Bram Vannieuwenhuyze (2018) and Colin Dupont’s Cartographie et pouvoir au XVIe siècle. L’atlas de Jacques de Deventer (2019). After discussing both works, it compares the divergent views of their authors on a number of crucial aspects, including the genesis and purpose of Van Deventer’s city atlas, the relationship between the loose maps and the atlas maps, and the ‘legend’ of his maps. This comparison is enriched with insights from several other recent articles on the subject. Lastly this contribution also proposes new ideas for future research.
