Abstract
PURPOSE Grade 3 neuroendocrine tumor (NET G3) is a novel pathologic category within gastro-entero-pancreatic (GEP) neuroendocrine neoplasms (NENs) but its clinical behavior and therapeutic management still remain challenging. Prognostic and predictive factors aiding NET G3 management are needed. PATIENTS AND METHODS We performed a retrospective analysis from 2015 to 2020 of all patients with > 20% Ki-67, well-differentiated NETs evaluated within our NEN-dedicated multidisciplinary team. We divided the sample according the timing of NET G3 diagnosis, the radiotracers distribution and Ki-67. We analyzed the correlation between these NET G3 features and clinical outcomes. RESULTS Among 3238 multidisciplinary discussion reports, we selected 55 patients, 48 from GEP and 7 from an occult GEP origin. In 45 patients, NET G3 diagnosis occurred at the beginning of clinical history (upfront-NET G3), whereas in 10, during the NET G1-G2 clinical history (late-NET G3). Patients with ≤ 30% (34/55) vs. > 30% Ki-67 (21/55) had a better overall survival (OS) (p = 0.042); patients with a homogeneous vs. inhomogeneous/negative 68Gallium(68Ga)-DOTA-Peptide Positron Emission Tomography (PET)/computed tomography (CT) showed a trend to a better OS, and a significant better progression-free survival (PFS) (p = 0.033). A better OS was observed for negative/inhomogeneous vs. homogeneous 18-fluorodeoxyglucose (18FDG)-PET/CT (p = 0.027). A trend to a better OS was reported in late- vs. upfront-NET G3, while the latter showed a significantly better response rate (RR) (p = 0.048). CONCLUSION Our findings suggested that Ki-67 cutoff, functional imaging and the timing to NET G3 diagnosis may help clinicians in more accurate selection of NET G3 management. Prospective studies are needed.

Abstract
BACKGROUND This study sought to describe the characteristics and the natural course of left ventricular hypertrophy (LVH) in a well-characterized consecutive cohort of infants of diabetic mothers (IDMs). METHODS Sixty consecutive IDMs with LVH have been retrospectively identified and enrolled in the study. All IDMs were evaluated at baseline and every 6 months until LV wall thickness regression, defined as the decrease of wall thickness measurement into the normal reference range for cardiac parameters (z-score > -2 and < 2). A comprehensive assessment was performed in those patients with diagnostic markers suggestive of a different cause and/or without significant reduction of the LVH during follow-up. RESULTS At 1-year follow-up, all IDMs showed a significant reduction of maximal wall thickness MWT (6.00 mm [IQR 5.00-712] vs. 5.50 mm [IQR 5.00-6.00], p-value <0.001; MWT-z-score: 4.86 [IQR 3.93-7.61] vs. 1.72 [IQR 1.08-2.85], p-value <0.001) compared to baseline, and all patients showed LV wall thickness regression or residual mild or moderate LVH (57%, 28%, and 12%, respectively), except 2 patients with persistent severe LVH, that after a comprehensive clinical-genetic assessment were diagnosed as Noonan syndrome with multiple lentigines. At multivariate analysis, MWT was negatively associated with LV wall thickness regression at 1-year follow-up (MWT-mm: OR 0.48[0.29-0.79], p-value = 0.004; MWT-z-score: OR 0.71[0.56-0.90], p-value = 0.004). CONCLUSIONS LVH in IDMs represents a benign condition with complete regression during the first years of life. In those patients without LV wall thickness regression, combined with clinical markers suggesting a specific disease, a complete work-up is required for a definite diagnosis.

Global Left Ventricular Myocardial Work Efficiency in Heart Failure Patients with Cardiac Amyloidosis: Pathophysiological Implications and Role in Differential Diagnosis. J Cardiovasc Echogr 2021; 31:157-164. [PMID: 34900551 PMCID: PMC8603776 DOI: 10.4103/jcecho.jcecho_16_21] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2021] [Revised: 04/19/2021] [Accepted: 07/10/2021] [Indexed: 01/15/2023] Open
Abstract
Introduction Cardiac amyloidosis (CA) is an infiltrative cardiomyopathy and a common cause of heart failure with preserved and mid-range ejection fraction (HFpEF and HFmrEF). Left ventricular (LV) systolic assessment is pivotal in differential diagnostic and prognostic stratification in CA. However, nondeformation and deformation-based parameters classically implied had many limitations. Myocardial work (MW) has been recently introduced for the evaluation of myocardial performance, in a load-independent fashion, in patients with cardiomyopathies. Aims This study aimed to evaluate MW parameters in LV performance assessment in CA and their possible role in differential diagnosis between AL and ATTR forms, compared with other echocardiographic parameters, also exploring the possible association between MW parameters and blood biomarkers. Materials and Methods The study population consisted of 25 patients with CA (10 with AL amyloidosis and 15 with wild-type ATTR [ATTRwt] form) and HFpEF or HFmrHF, enrolled between March 2018 and December 2019, undergoing a comprehensive clinical, biochemical, and imaging evaluation. Ten healthy individuals were studied as controls. ATTR patients had a noninvasive diagnosis of wtATTR-CA (positive 99mTc-hydroxy methylene-diphosphonate scintigraphy with a negative hematological screening), while AL patients underwent endomyocardial biopsy. All patients underwent standard transthoracic echocardiography. MW and related indices were estimated using a vendor-specific module. Results Compared to the ATTRwt group, patients in the AL group showed a more pronounced myocardial performance impairment assessed by Global Word Efficiency (GWE: 83.5% ± 6.3% vs. 88.2% ± 3.6%; P = 0.026). In multiple linear regression analysis, cardiac troponin I (Β = -0.55; P < 0.0001), global longitudinal strain (Β =0.35; P < 0.008), and regional relative strain ratio (Β = -0.30; P < 0.016) were significant predictors of GWE reduction in CA patients. At receiver operating characteristics curve analysis, among all other deformation-based and nondeformation-based echocardiographic parameters, GWE showed the highest area under the curve (AUC) (AUC 0.74; 95% CI: 0.55-0.96; P < 0.04). The optimal cutoff was determined by sensitivity/specificity analysis: a GWE < 86.5% identified patients with AL amyloidosis with a sensitivity and specificity, respectively, of 80.0% and 66.7%. Conclusions The results of our pivotal study seem to highlight the importance of new deformation parameters to study myocardial performance in patients with CA, and to differentiate between AL CA and ATTR CA.

Abstract
Abstract
Aims
This study aimed to validate the increased wall thickness (IWT) score, a multiparametric echocardiographic score to facilitate diagnosis of cardiac amyloidosis (CA), in an independent population of patients with increased LV wall thickness suspicious for CA.
Methods and results
Between January 2019 and December 2020, 152 consecutive patients with increased LV wall thickness suspicious for CA were included. For all patient, the multiparametric echocardiographic score (IWT score) was calculated. To validate the diagnostic accuracy of an IWT score ≥8 to predict the diagnosis of CA, sensibility (Se), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV), and predictive accuracy (PA) were calculated. Among the 152 patients included in the study, 50 (33%) were diagnosed as CA, 25 (16%) had severe aortic stenosis, 25 (16%) had hypertensive remodelling, and 52 (34%) had hypertrophic cardiomyopathy. Among the 50 and 102 patients with and without CA, 19 (38%) and 1 (1%) showed an IWT score ≥8, respectively. Overall, the diagnostic accuracy of an IWT score ≥8 for the diagnosis of CA in our population was the following: Se 38% (95% CI: 25–53%); Sp 99% (95% CI: 95–100%); PPV 95% (95% CI: 72–99%); NPV 77% (95% CI: 73–80%); PA 79% (95% CI: 72–85%).
Conclusions
This study reports the first external validation of the IWT score for the diagnosis of CA in patients with increased LV wall thickness. A score ≥8 showed a high Sp, PPV and PA, suggesting that the IWT score can be used to identify CA patients in those with increased LV wall thickness.

Abstract
Abstract
Aims
To evaluate to role of bisoprolol to control symptoms and left ventricular outflow tract obstruction (LVOTO) in a consecutive cohort of adults with hypertrophic cardiomyopathy (HCM).
Methods and results
In this retrospective study, patients with HCM with an LVOT gradient ≥50mmHg after Valsalva manoeuvre and New York Heart Association (NYHA) class II-III symptoms were assigned to receive bisoprolol (starting at 1.25 mg daily). The initial dose was increased every two weeks to achieve the target in LVOT gradient <30 mmHg or the maximum tolerated dose. The primary endpoint was the achievement of a LVOT gradient <30 mmHg and ≥1 NYHA class improvement. The secondary endpoints were proportion of patients with LVOT gradient <30 mmHg or < 50 mmHg, proportion of patients with ≥1 NYHA class improvement, and change from baseline in LVOT gradient. Between December 2001 and December 2020, 92 patients were enrolled into the study. Sixteen (17%) patients on bisoprolol met the primary endpoint. Bisoprolol reduced the LVOT gradient to less than 30 mmHg in 33 (36%) patients, to less than 50 mmHg in 57 (62%), and improved NYHA class in 30 (33%). The mean reduction of LVOT gradient on bisoprolol was 28 (±14) mmHg and the percentage reduction was 42 (±21)%. In 35 (39%) patients, bisoprolol did not reduce the gradient to less than 50 mmHg requiring disopyramide and/or myectomy to achieve this goal.
Conclusions
Treatment with bisoprolol was well-tolerated and effective in relieving obstruction and improving symptoms in a significant proportion of patients with symptomatic obstructive HCM.

Abstract
AIMS Children presenting with hypertrophic cardiomyopathy (HCM) in infancy are reported to have a poor prognosis, but this heterogeneous group has not been systematically characterized. This study aimed to describe the aetiology, phenotype, and outcomes of infantile HCM in a well-characterized multicentre European cohort. METHODS AND RESULTS Of 301 children diagnosed with infantile HCM between 1987 and 2019 presenting to 17 European centres [male n = 187 (62.1%)], underlying aetiology was non-syndromic (n = 138, 45.6%), RASopathy (n = 101, 33.6%), or inborn error of metabolism (IEM) (n = 49, 16.3%). The most common reasons for presentation were symptoms (n = 77, 29.3%), which were more prevalent in those with syndromic disease (n = 62, 61.4%, P < 0.001), and an isolated murmur (n = 75, 28.5%). One hundred and sixty-one (53.5%) had one or more co-morbidities. Genetic testing was performed in 163 (54.2%) patients, with a disease-causing variant identified in 115 (70.6%). Over median follow-up of 4.1 years, 50 (16.6%) underwent one or more surgical interventions; 15 (5.0%) had an arrhythmic event (6 in the first year of life); and 48 (15.9%) died, with an overall 5 year survival of 85%. Predictors of all-cause mortality were an underlying diagnosis of IEM [hazard ratio (HR) 4.4, P = 0.070], cardiac symptoms (HR 3.2, P = 0.005), and impaired left ventricular systolic function (HR 3.0, P = 0.028). CONCLUSIONS This large, multicentre study of infantile HCM describes a complex cohort of patients with a diverse phenotypic spectrum and clinical course. Although overall outcomes were poor, this was largely related to underlying aetiology emphasizing the importance of comprehensive aetiological investigations, including genetic testing, in infantile HCM.

Abstract
Cardiac amyloidosis is an infiltrative disorder caused by transthyretin or immunoglobulin free light-chain deposition, which determines clinical disease with similar phenotype but different time course, prognosis and therapy. Multimodality imaging is the cornerstone for disease diagnosis and management. Multimodality imaging has revolutionized the approach to the disease favoring its awareness and simplifying its diagnosis, especially in ATTR cardiac amyloidosis. This describes the different imaging tools, from the traditional to the more novel ones, and highlights the different approach in each different setting (prognosis, subtyping, prognosis, monitoring disease progression, and response to therapy).

Abstract
Fabry disease (FD, OMIM 301500) is an X-linked lysosomal storage disease caused by pathogenic variants in the GLA gene. Cardiac involvement is common in FD and is responsible for impaired quality of life and premature death. The classic cardiac involvement is a nonobstructive form of hypertrophic cardiomyopathy, usually manifesting as concentric left ventricular hypertrophy, with subsequent arrhythmogenic intramural fibrosis. Treatment of patients with FD should be directed to prevent the disease progression to irreversible organ damage and organ failure. The aim of this review is to describe the current state of knowledge regarding cardiovascular involvement in FD, focusing on clinical and instrumental features, cardiovascular management, and targeted therapy.

Abstract
Transthyretin cardiac amyloidosis (ATTR-CA) is a systemic disorder resulting from the extracellular deposition of amyloid fibrils of misfolded transthyretin protein in the heart. ATTR-CA is a life-threatening disease, which can be caused by progressive deposition of wild type transthyretin (wtATTR) or by aggregation of an inherited mutated variant of transthyretin (mATTR). mATTR Is a rare condition transmitted in an autosomal dominant manner with incomplete penetrance, causing heterogenous phenotypes which can range from predominant neuropathic involvement, predominant cardiomyopathy, or mixed. Diagnosis of ATTR-CA is complex and requires integration of different imaging tools (echocardiography, bone scintigraphy, magnetic resonance) with genetics, clinical signs, laboratory tests, and histology. In recent years, new therapeutic agents have shown good efficacy and impact on survival and quality of life in this subset of patients, nevertheless patients affected by ATTR-CA may still carry an unfavorable prognosis, thus highlighting the need for new therapies. This review aims to assess cardiovascular involvement, diagnosis, and management of patients affected by ATTR-CA.

Abstract
"Sudden unexplained death (SUD) is a tragic event for both the family and community, particularly when it occurs in young individuals. Sudden cardiac death (SCD) represents the leading form of SUD and is defined as an unexpected event without an obvious extracardiac cause, occurring within 1 hour after the onset of symptoms. In children, the main causes of SCD are inherited cardiac disorders, whereas coronary artery diseases (congenital or acquired), congenital heart diseases, and myocarditis are rare. The present review examines the current state of knowledge regarding SCD in children, discussing the epidemiology, clinical causes, and prevention strategies."

Abstract
Friedreich ataxia (FRDA) is an autosomal recessive neurodegenerative disorder caused by a homozygous GAA triplet repeat expansion in the frataxin gene. Cardiac involvement, usually manifesting as hypertrophic cardiomyopathy, can range from asymptomatic cases to severe cardiomyopathy with progressive deterioration of the left ventricular ejection fraction and chronic heart failure. The management of cardiac involvement is directed to prevent disease progression and cardiovascular complications. However, direct-disease therapies are not currently available for FRDA. The present review aims to describe the current state of knowledge regarding cardiovascular involvement of FRDA, focusing on clinical-instrumental features and management of cardiac manifestation.

Abstract
INTRODUCTION Sunitinib still represents a milestone in the treatment for progressive, well-differentiated, advanced panNETs. AREAS COVERED We performed an evidence reappraisal to critically discuss its safety profile. We included nine studies, five clinical trials and four real-world (RW) studies. Within non-real-world (NRW) studies, diarrhea was the most frequent clinical AE. With regard to G3-4 AEs, fatigue and hypertension were the two most frequent, while neutropenia was the most recurrent hematological one. Considering four real-world trials, hand-foot-syndrome (HFS) was the most frequent clinical any-grade AE of any grade and neutropenia was the most common G3-4. Alongside to the AEs rate, the discontinuation rate of sunitinib due to TRAEs was variable among all the nine selected studies, ranging from 10% to 35% in the NRW setting and from 7% to 31% in the RW setting. Conversely, temporary interruption is an accepted strategy to reduce toxicity, even though not specifically tested in pan-NET. EXPERT OPINION Till now, sunitinib continues to be one of the main therapeutic options for patients with well differentiated advanced panNETs, potentially covering any line of treatment. Therefore, tolerability plays a crucial role to increase adherence to therapy and maximize QoL.

Abstract
Abstract
Background
Cardiac amyloidosis (CA) is an infiltrative disorder characterized by left ventricular (LV) thickening and dysfunction. Due to it poor prognosis its early detection and differential diagnosis among other forms of cardiomyopathies is fundamental.
Purpose
This study aimed to compare the diagnostic accuracy of LV classical and and novel echocardiographic parameters in differentiating CA from other forms of genetic and non-genetic cardiomyopathies with hypertrophic phenotype.
Methods
We included 50 patients with CA (26 pts with AL and 24 pts with wild type ATTR form) and 75 patients with LV hypertrophy (LVH) [25 patients with hypertrophic cardiomyopathy (HCM), 25 with hypertensive cardiomyopathy (HypCM), and 25 with aortic stenosis (AS)]. Besides routine echocardiographic measurements, we analysed standard and novel echo parameters implied in LV assessment [LV ejection fraction (LVEF), myocardial contraction fraction (MCF), global longitudinal strain (GLS), relative regional strain ratio (RRSR), ejection fraction on strain ratio (EFSR)], included novel Myocardial Work (MW) parameters [Global Work Index (GWI), Global Constructive Work (GCW), Global Wasted Work (GWW), Global Work Efficiency (GWE)].
Results
Patients in CA group showed a smallest LV cavity size, higher LV mass and, consequently, a more pronounced concentric hypertrophy compared to LVH group. All LV systolic parameters where more impaired in CA than in LVH group. At ROC curve analysis, among all others, GCW showed the best performance in discriminating CA from LVH (AUC 0.886; 95% CI: 0.819–0.954; P<0,0001), with a cut-off value <1473 mmHg% showing good sensitivity and specificity (90% and 82%, respectively). At linear regression analysis GCW correlated with IVSD (P<0,0001), PWD (p<0,0001), RWT ratio (p<0,0001), LVMi (p<0,0001), MCF (P<0,0001), LVESV (p<0,002), LVEF (P<0,0001), EFSR (p<0,0001) and RRSR (p<0,0001). At multivariate analysis, PWD (P<0,029) and RWT ratio (p<0,014) were the only parameters associated. At 24 months follow-up there were 15 deaths in the CA group and 4 in LVH group. At Kaplan-Meier analysis the overall survival free of cardiovascular death was reduced in the lowest GCW interquartile ranges (log-rank χ2 21,5; p<0,0001). At Cox hazard ratio analysis GCW (β 1,233; 95% CI: 1,201–1,246; P<0,0001) was the only prognostic parameter associated with cardiovascular mortality.
Discussion
Although CA and and LVH have with similar phenotype, they differ greatly in terms of systolic function. The MW, estimated by non-invasive pressure-strain loops, is a novel method for a load-independent LV systolic function assessment. In the present study the GCW showed the best ability in detecting CA in comparison to other parameters usually implied in clinical practice.
Conclusion
Myocardial performance is significantly reduced in CA compared to other forms of LVH. GCW showed to be a promising novel diagnostic and prognostic factor in this setting.

Abstract
Abstract
Background
Left ventricular hypertrophy (LVH) in infants of diabetic mothers (IDMs) has been generally considered a benign condition, which usually regresses as the stimulus for the insulin production disappears, resulting in normalized left ventricular wall thickness in the 6 months of life. However, these conclusions have been based on small, mostly outdated cohort studies. Indeed, it has been recently shown that increased left ventricular mass persists in late infancy (6 to 12 months), long after the intrauterine exposure has been removed, suggesting that other factors may potentially contribute.
Purpose
This study sought to describe the characteristics and the natural course of LVH in a well-characterized consecutive cohort of IDMs.
Methods
Sixty consecutive IDMs with LVH have been retrospectively identified and enrolled in the study. All IDMs were evaluated at baseline and every 6 months until LV wall thickness regression, defined as the decrease of wall thickness measurement into the normal reference range for cardiac parameters (z-score >−2 and <2). A comprehensive assessment was performed in those patients with diagnostic markers suggestive of a different cause and/or without significant reduction of the LVH during follow-up.
Results
At 1-year follow-up, all IDMs showed a significant reduction of maximal wall thickness (MWT) (MWT-mm: 6.67±2.37 vs. 5.83±1.70, p-value<0.001; MWT-z-score: 6.67±4.71 vs. 2.39±2.55, p-value<0.001) and left ventricular outflow tract (LVOT) gradient (15.35±15.58 vs. 11.22±8.14, p-value<0.004), compared to baseline, and all patients showed LV wall thickness regression or residual mild or moderate LVH (57%, 28%, and 12%, respectively) (Figure 1), except 2 patients with persistent severe LVH, that after a comprehensive clinical-genetic assessment were diagnosed as Noonan syndrome with multiple lentigines.
At multivariate analysis, MWT was significantly associated with LV wall thickness regression at 1-year follow-up (MWT-mm: OR 0.48 [0.29–0.79], p-value=0.004; MWT-z-score: OR 0.71 [0.56–0.90], p-value=0.004) in an inversely proportional fashion.
Overall, 59%, 72% and 79% of IDMs with LVH showed a complete LV wall thickness regression at 1-year, 2-year and 3-year follow-up, respectively (Figure 2). Excluding the two patients with a different cause of LVH, all IDMs showed a LV wall thickness regression in the first 6 years of life.
Conclusions
LVH in IDMs represents a benign condition with complete regression during the first years of life. In those patients without LV wall thickness regression, combined with clinical markers suggesting a specific disease, a complete work-up is required for a definite diagnosis.

Abstract
Abstract
Background
Hypertrophic cardiomyopathy (HCM) is characterized by extremely varied phenotypic expression ranging from asymptomatic to heart failure (HF) to sudden cardiac death (SCD). Although children with HCM are considered in the highest risk spectrum, the most common recommendations on pharmacological and non-pharmacological treatment (i.e. drugs, ICD, septal reduction procedures, inclusion in cardiac transplantation list) are often disregarded or too much postponed in this setting and strong evidence-based risk prediction models are missing. A systematic cardiopulmonary exercise test (CPET) assessment might be helpful to disclose an unsuspected functional limitation.
Purpose
The aim of our multicenter retrospective study was to investigate possible clinical insights, in terms of functional and prognostic assessment, coming from a full CPET assessment in a cohort of pediatric HCM outpatients aged less than 18 years old.
Methods
Sixty consecutive pediatric HCM outpatients aged <18 years-old were enrolled, each of them undergoing a full clinical assessment including a CPET; a group of 60 healthy subjects served as controls. An unique composite end-point of HF-related and SCD or SCD-equivalent events was also explored. During a median follow-up of 53 months, a total of 13 HF- and 7 SCD-related first events were collected.
Results
An impaired exercise capacity, consisting on peak VO2 values <80% of the predicted, has been found in the 78% of the study sample (n. 47 patients). Despite most of the HCM patients were classified in NYHA I functional class, most of them (n. 33, 73%) showed a reduced exercise capacity, the percentage of impaired exercise capacity raising in the NYHA II group (n. 14 patients, 93%).
Respect to the control Group, the HCM patients showed a significantly poorer functional status in terms of maximum workload achieved, peak VO2 (regardless the adopted correction), circulatory power and VE/VCO2 slope values (Figure 1, panel A).
HCM patients who experience adverse events during the follow-up (Event Group) showed the worst CPET profile (Figure 1, panel B).
The composite end-point occurred more frequently in patients with the worst CPETs' profiles. At the univariate analysis, peak VO2% was the variable with the strongest association with adverse events at follow-up (C-index=0.72, p=0.025) and a cut-off value equal to 60% was the most accurate in identifying those patients at the highest risk (Figure 2).
Conclusions
Our findings support the role of CPET analysis as an insightful approach in the young HCM clinical management. In a group of young asymptomatic or slightly symptomatic HCM patients, the CPET allowed us to estimate accurately their functional capacity and to disclose a portion of un-recognized exercise impairment. Our data argue in favor of a possible role of some CPET-derived variables in the early identification of those young HCM patients at highest risk of HCM related events.

Abstract
Abstract
Background
Left atrial function (LAF) is emerging as a novel determinant of clinical status and outcome in cardiomyopathies. However, few studies compare LAF between CA subgroups and between CA and other hypertrophic cardiomyopathies.
Purpose
This study explores the LAF in cardiomyopathies with hypertrophic phenotype and between CA subgroups and its consequences on clinical status, haemodynamic consequences and survival.
Methods
We enrolled 50 patients with CA (26 with AL and 24 with wild type ATTR form), 75 patients with LV hypertrophy (LVH) [25 with hypertrophic cardiomyopathy (HCM), 25 with hypertensive cardiomyopathy (HypCM), and 25 with aortic stenosis (AS)]. Besides routine echocardiographic measurements, we analysed LAF using the phasic method (LAEI as reservoi, LAPEF as conduit, LAAEF as pump and TLAEF as total emptying LA function).
Results
The ATTR showed higher atrial dimensions with a significant reduction in the reservoir and total LA emptying function compared to the AL group (see Table 1). Instead, compared to the LVH group, CA patients showed higher atrial dimension with all LAF phasic parameters reduced, higher LV filling pressures and reduced biventricular function. Then, we further divided the CA and LVH group into subgroups based on the presence or absence of LA dysfunction (LADys+) defined as TLAEF values below the median [TLAEF <50,2%; range 9,3–70,9%]. Patients in CA/LADys+ group showed the worst NYHA class, higher sPAP and lower values of TAPSE and TAPSE/sPAP ratio (see Figure 2). After a follow-up of 24 months, 19 patients died from cardiovascular causes [0/8 in CA/LADys-, 15/42 in CA/LADys+, 0/60 in LVH/LADys- and 4/26 in LVH/LADys+ group; (log-rank χ2 29,6; p<0,0001)]. To predict whether LAF could predict cardiovascular deaths sequential multivariate model was employed, and TLAEF was entered together with established clinical and echocardiographic parameters (NYHA class, LAVI, E/Em, sPAP, TAPSE and TAPSE/sPAP ratio). At the final backward analysis, LAVI, TAPSE/sPAP and TLAEF were the independent prognosticators for adverse events.
Discussion
The LAF is significantly impaired in CA and associated with worst clinical status, higher incidence of RV dysfunction and higher LV filling and pulmonary pressure. Moreover, LADys is significant associated with higher cardiovascular mortality. LADys results from chronic pressure overload due to LA's exposition to the higher LV diastolic pressure due to impaired LV compliance, and from direct infiltration in CA The result is a progressive LA remodelling with an increased LA pressure and consequenT backward transmission to the pulmonary venous system and to RV.
Conclusions
The TLAEF is a novel parameter of LAF that correlates with increased pulmonary vascular resistance and RV dysfunction. It seems a promising novel prognosticator and amarker of the haemodynamic consequences of LADys.

Abstract
Abstract
Background
Right ventricular (RV) dysfunction in cardiomyopathies is a consequence of chronic overload (i.e. aortic stenosis) or direct involvement of systemic disorders (i.e. cardiac amyloidosis, CA). The Tricuspid Annular Plane Systolic Excursion/Systolic Pulmonary Artery Pressure ratio (TAPSE/sPAP) has been recently proposed as a surrogate of RV-arterial coupling (RVAC) in many cardiac disorders.
Purpose
This study aims to compare RVAC between CA subgroups and between CA and other forms of genetic and non-genetic cardiomyopathies with hypertrophic phenotype.
Methods
We enrolled 50 patients with CA (26 pts with AL and 24 pts with wild type ATTR form), 75 patients with LV hypertrophy (LVH) [25 patients with HCM, 25 with hypertensive cardiomyopathy (HypCM), and 25 with aortic stenosis]. We analysed right chambers dimensions and classical and novel parameters of RV function [TAPSE, TAPSE/sPAP, St (S' wave at RV TDI), global (RVGLS) and free-wall (RVFWS) strain].
Results
The ATTR group showed higher right dimensions than AL, without differences in all RV systolic parameters (see Table 1). Compared to the LVH group, CA patients showed no differences in RV dimensions while RV systolic parameters, included the TAPSE/sPAP ratio, were significantly reduced. At ROC curve analysis TAPSE (AUC 0.877; 95% CI: 0.811–0.943; p<0,0001) and TAPSE/sPAP ratio (AUC 0.859; 95% CI: 0.783–0.935; p<0,0001) showed the best ability in discriminating CA among other forms of LVH (cut-off 20,5 mm for TAPSE with a sensibility of 80,5% and specificity of 78,8%; cut-off 0,62 for TAPSE/sPAP ratio with a sensibility of 85,4% and a specificity 81,8%). At Kaplan-Meier estimation, the TAPSE/sPAP ratio showed a significantly reduced survival in the lowest interquartile ranges. Moreover, at multivariate analysis TAPSE/sPAP was the only independent prognostic factor (β −5,644; 95% IC: 0,000–0,522; p<0,027).
Discussion
The RVAC is significantly impaired in CA compared to the LVH group but not between CA subgroups. TAPSE/sPAP proved to be a novel echocardiographic parameter useful in discriminating CA among genetic and non-genetic forms of LVH, and that also show prognostic significance.

Abstract
Heart failure (HF) is an important health care issue in children because of its considerable morbidity and mortality. Advanced HF encompasses patients who remained symptomatic despite optimal medical treatment and includes patients who require special management, such as continuous inotropic therapy, mechanical circulatory support, or heart transplantation (HT). HT is the gold standard for children with advanced HF; nonetheless, the number of suitable donors has not increased for decades, leading to prolonged waitlist times and increased mortality rates. Therefore, the role of pediatric mechanic circulatory support has been assessed as an alternative treatment in patients in whom heart transplant could not be performed. The authors discuss the epidemiology, causes, pathophysiology, clinical manifestation, medical treatment, device therapy, and HT in pediatric HF, and a particular emphasis was posed on patients with advanced HF.

Abstract
BACKGROUND Temozolomide (TEM) is an active treatment in metastatic neuroendocrine tumors (NETs). Patients affected by glioblastoma multiforme or advanced melanoma treated with TEM who have deficiency of O6-methylguanine DNA methyltransferase (MGMT) have a better responses and survival. However, the predictive role of MGMT in patients with NETs treated with TEM is still debated. METHODS We conducted a systematic review of the literature and meta-analysis, based on PRISMA methodology, searching in the main databases (PubMed, Embase, Scopus, Web of Science, Cochrane Library and clinical trial.gov) and the proceedings of the main international congresses, until April 26, 2021. RESULTS Twelve out of 616 articles were selected for our analysis, regarding a total of 858 NET patients treated with TEM-based chemotherapy. The status of MGMT had been tested in 513 (60%) patients, using various methods. The pooled overall response rate (ORR) was higher in MGMT-deficient compared with MGMT-proficient NETs, with a risk difference of 0.31 (95% confidence interval, CI: 0.13-0.50; p < 0.001; I2: 73%) and risk ratio of 2.29 (95% CI: 1.34-3.91; p < 0.001; I2: 55%). The pooled progression free survival (PFS) (hazard ratio, HR = 0.56; 95% CI: 0.43-0.74; p < 0.001) and overall survival (OS) (HR = 0.41; 95% CI: 0.20-0.62; p = 0.011) were longer in MGMT-deficient versus MGMT-proficient NETs. CONCLUSIONS Our meta-analysis suggested that MGMT status may be predictive of TEM efficacy. However, due to the high heterogeneity of the evaluated studies the risk of biases should be considered. On this hypothesis future homogeneous prospective studies are warranted.

Abstract
INTRODUCTION This study aimed to validate the increased wall thickness (IWT) score, a multiparametric echocardiographic score to facilitate diagnosis of cardiac amyloidosis (CA), in an independent population of patients with increased LV wall thickness suspicious for CA. METHODS Between January 2019 and December 2020, 152 consecutive patients with increased LV wall thickness suspicious for CA were included. For all patient, the multiparametric echocardiographic score (IWT score) was calculated. To validate the diagnostic accuracy of an IWT score ≥ 8 to predict the diagnosis of CA, sensibility (Se), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV), and predictive accuracy (PA) were calculated. RESULTS Among the 152 patients included in the study, 50 (33%) were diagnosed as CA, 25 (16%) had severe aortic stenosis, 25 (16%) had hypertensive remodeling, and 52 (34%) had hypertrophic cardiomyopathy. Among the 50 and 102 patients with and without CA, 19 (38%) and 1 (1%) showed an IWT score ≥ 8, respectively. Overall, the diagnostic accuracy of an IWT score ≥ 8 for the diagnosis of CA in our population was the following: Se 38% (95%CI 25-53%); Sp 99% (95%CI 95-100%); PPV 95% (95%CI 72-99%); NPV 77% (95%CI 73-80%); PA 79% (95%CI 72-85%). CONCLUSIONS This study reports the first external validation of the IWT score for the diagnosis of CA in patients with increased LV wall thickness. A score ≥ 8 showed a high Sp, PPV and PA, suggesting that the IWT score can be used to identify CA patients in those with increased LV wall thickness.

Abstract
Background The aims of this study were: to investigate the capacity of the rare disease healthcare network in Campania to diagnose patients with rare diseases during the outbreak of Covid-19; and to shed light on problematic diagnoses during this period. Methods To describe the impact of the Covid-19 pandemic on the diagnosis of patients with rare diseases, a retrospective analysis of the Campania Region Rare Disease Registry was performed. A tailored questionnaire was sent to rare disease experts to investigate major issues during the emergency period. Results Prevalence of new diagnoses of rare disease in March and April 2020 was significantly lower than in 2019 (117 versus 317, P < 0.001 and 37 versus 349, P < 0.001, respectively) and 2018 (117 versus 389, P < 0.001 and 37 versus 282, P < 0.001, respectively). Eighty-two among 98 rare disease experts completed the questionnaire. Diagnostic success (95%), access to diagnosis (80%) and follow-up (72%), lack of Personal Protective Equipment (60%), lack of Covid-19 guidelines (50%) and the need for home therapy (78%) were the most important issues raised during Covid-19 outbreak. Conclusions This study describes the effects of the Covid-19 outbreak on the diagnosis of rare disease in a single Italian region and investigates potential issues of diagnosis and management during this period.

Abstract
The usefulness of cardiopulmonary exercise test (CPET) in adult hypertrophic cardiomyopathy (HCM) patients is well-known, whereas its role in pediatric HCM patients has not yet been explored. The present study investigates possible insights from a CPET assessment in a cohort of pediatric HCM outpatients in terms of functional and prognostic assessment. Sixty consecutive pediatric HCM outpatients aged <18 years old were enrolled, each of them undergoing a full clinical assessment including a CPET; a group of 60 healthy subjects served as controls. A unique composite end-point of heart failure (HF) related and sudden cardiac death (SCD) or SCD-equivalent events was also explored. During a median follow-up of 53 months (25th–75th: 13–84 months), a total of 13 HF- and 7 SCD-related first events were collected. Compared to controls, HCM patients showed an impaired functional capacity with most of them showing peak oxygen uptake (pVO2) values of <80% of the predicted, clearly discrepant with functional New York Heart Association class assessment. The composite end-point occurred more frequently in patients with the worst CPETs’ profiles. At the univariate analysis, pVO2% was the variable with the strongest association with adverse events at follow-up (C-index = 0.72, p = 0.025) and a cut-off value equal to 60% was the most accurate in identifying those patients at the highest risk.
