Background: Cardiac amyloidosis (CA) is cardiomyopathy with a hypertrophic phenotype characterised by diffuse deposition of anomalous fibrillar proteins in the extracellular matrix., Objectives: To evaluate the prevalence and diagnostic value of extra left ventricle echocardiographic findings in patients with left ventricular (LV) hypertrophic phenotype and amyloid deposition., Methods: A group of 146 patients with LV thickness ≥15 mm were enrolled: 70 patients who received a definite diagnosis of sarcomeric hypertrophic cardiomyopathy (HCM group) and 76 patients with transthyretin cardiac amyloidosis (CA group). Echocardiographic analysis of crista terminalis (CriT), atrio-ventricular plane (AVP), mitro-aortic lamina (MAL), anterior ascending aortic wall, interatrial septum (IAS), Eustachian valve (EusV) and coumadin ridge (CouR) was performed in all patients, and these structures were compared among the two groups., Results: CA group showed significantly higher dimensions of CriT, IAS, CouR, AVP, MAL and IAS compared to the HCM group. The logistic analysis showed that LV EF, LV septal thickness, CriT presence, CriT area, MAL and IAS were all predictors of CA in univariate analyses. The stepwise multivariate analysis showed independent predictors of CA: CriT area, MAL and LVEF. According to areas under the receiver operating characteristic curves the best cut-off values to determine CA were identified (IAS > 9 mm, MAL > 7 mm, CriT > 9 mm 2 ). Among these 3 independent predictors, IAS > 9 mm had the best specificity (96%) and positive predictive value (93%) in identifying CA., Conclusions: evidence of extra left ventricle sites of amyloid deposition is a frequent finding in CA. In the context of hypertrophic phenocopies, an increased thickness of IAS, and/or CT and/or MAL should suggest a diagnosis of transthyretin CA.

Background: Current guidelines do not recommend periodically repeating echocardiograms in the follow-up of stable heart failure patients with reduced ejection fraction (HFrEF). The objective of the study was to verify the additional prognostic information provided by a comprehensive re-assessment of their cardiac function and hemodynamic profile at Doppler echocardiography in HFrEF patients., Methods: Retrospective analysis of 769 stable HFrEF outpatients who underwent two complete echocardiograms, at baseline and at re-assessment. Main candidate predictors of prognosis were: left ventricular (LV) filling pattern, pulmonary artery systolic pressure (PASP) and right ventricular function (TAPSE). Age, LV ejection fraction, mitral regurgitation severity, NYHA class, brain natriuretic peptide plasma levels at baseline, and their changes at 12 months, were used as covariates. Median follow-up was 30 months. All-cause death was the study end-point., Results: At baseline, restrictive filling pattern and low TAPSE were significant predictors of poor prognosis. At re-evaluation, persistently restrictive/worsened filling pattern, persistently-low/worsened TAPSE and worsened PASP, were associated with poorer survival. A significant interaction between changes in TAPSE, PASP and LV filling pattern was observed: in the restrictive pattern subgroup, survival was poorer in worsened/persistently low TAPSE (p < 0.01); in non-restrictive pattern subgroup, survival was poorer in worsened/persistently elevated PASP (p = 0.01). The re-assessment model improved the C-index from 0.69 to 0.74 (P < 0.01) compared to baseline model., Conclusions: Doppler echocardiographic re-assessment of LV filling pattern, PASP and TAPSE allows a better prognostic stratification of HFrEF outpatients than baseline evaluation and is additional to changes in BNP and NYHA class., Competing Interests: Declaration of Competing Interest None., (Copyright © 2020.

Volume overload and fluid congestion are a fundamental issue in the assessment and management of patients with heart failure (HF). Recent studies have found that in acute decompensated heart failure (ADHF), right and left-sided pressures generally start to increase before any notable weight changes take place preceding an admission. ADHF may be a problem of volume redistribution among different vascular compartments instead of, or in addition to, fluid shift from the interstitial compartment. Thus, identifying heterogeneity of volume overload would allow guidance of tailored therapy. A comprehensive evaluation of congestive HF needs to take into account myriad parameters, including physical examination, echocardiographic values, and biomarker serum changes. Furthermore, potentially useful diagnostic tools include bioimpedance to measure intercompartmental fluid shifts, and evaluation of ultrasound lung comets to detect extravascular lung water., (Copyright © 2020 Elsevier Inc.

Background and Aims: It is unknown whether the prognostic role of diabetes (T2DM) in outpatients with chronic heart failure (CHF) is independent of the most important echocardiographic markers of poor prognosis. The aims of this analysis were to evaluate whether T2DM modifies the risk of mortality in CHF patients stratified by etiology of disease or by right-ventricular to pulmonary arterial coupling at echocardiography and to evaluate how T2DM interacts with the prognostic role of cardiac plasma biomarkers., Methods and Results: This is a retrospective analysis of 1627 CHF outpatients who underwent a complete echocardiographic examination. During a median follow-up period of 63 months 255 patients died. Poor right-ventricular to pulmonary arterial coupling and reduced left ventricular ejection fraction were independent predictors of outcome, whereas ischemic etiology and T2DM were not. T2DM interacted with etiology increasing the risk of mortality by 32% among patients with ischemic disease (p = 0.003). Elevated hsTNI plasma levels were associated with poor survival in T2DM but not in non-diabetic patients., Conclusion: T2DM signals a worse outcome in ischemic CHF patients regardless of the echocardiographic phenotype. High plasma levels of hsTNI are stronger predictors of mortality in CHF patients with T2DM than in patients without diabetes., Competing Interests: Declaration of Competing Interest None declared., (Copyright © 2020.

Aims: Echocardiographic assessment of left ventricular filling pressures is performed using a multi-parametric algorithm. Unselected sample of patients with heart failure with reduced ejection fraction (HFrEF) patients may demonstrate an indeterminate status of diastolic indices making interpretation challenging. We sought to test improvement in the diagnostic accuracy of standard and strain echocardiography of the left ventricle and left atrium (LA) to estimate a pulmonary capillary wedge pressure (PCWP) > 15 mmHg in patients with HFrEF., Methods and Results: Out of 82 consecutive patients, 78 patients were included in the final analysis and right heat catheterization, and echocardiogram was performed simultaneously. According to the univariable analysis, E wave velocity, the ratio between E-wave/A-wave (E/A, area under the curve [AUC] = 0.81, respectively), isovolumic relaxation time (AUC = 0.83), pulmonary vein D wave (AUC = 0.84), pulmonary vein S/D Ratio (AUC = 0.85), early pulmonary regurgitation velocity (AUC = 0.80), and accelerationa time at right ventricular out-flow tract (RVOT AT, AUC = 0.84) identified with the highest accuracy PCWP > 15 mmHg. They were all tested in multivariate analysis, and they were not independently correlated with PCWP. Tricuspid regurgitation (TR) velocity was measurement with the highest predictive value in identifying PCWP > 15 mmHg (AUC = 0.89), compared with other established parameters such as the ratio between e-wave velocity divided by mitral annular e' velocity (E/e'), deceleration time, or LA indexed volume (LAVi), which all reached a lower accuracy level (AUC = 0.75; 0.78; 0.76). Among strain measures, global longitudinal strain in four chamber view (GLS 4ch), the ratio between e-wave velocity divided by mitral annular e' strain rate (E/e'sr), and LA longitudinal strain at the reservoir phase were helpful in estimating elevated PCWP (AUC = 0.77; 0.76; 0.75). According to multivariable analysis, the following two models had the greatest accuracy in detecting PCWP > 15 mmHg: (i) TR velocity, LAVi, and E wave velocity (receiver operating characteristic [ROC]-AUC = 0.98), (ii) AT RVOT, LAVi and GLS 4ch (ROC-AUC = 0.96). Neither E/A (ROC-AUC = 0.81) nor E/e' (ROC-AUC = 0.75) was an independent predictor when included in the model. The two MODELS were applicable to the entire population and demonstrated better agreement with the invasive reference (91% and 88%) than the guidelines algorithm (77%) regardless of the type of rhythm., Conclusions: Our suggested echocardiographic approach could be used to potentially reduce the frequency of "doubtful" classification and increase the accuracy in predicting elevated left ventricular filling pressure leading to a decrease in the number of invasive assessment made by right heart catheterization., (© 2020 The Authors.

Hyperkalemia in heart failure is a condition that can occur with relative frequency because it is related to pathophysiological aspects of the disease, and favored by drugs that form the basis of chronic cardiac failure therapy. Often, associated comorbidities, such as kidney failure or diabetes mellitus can further adversely affect potassium levels. Hyperkalemia can result in acute and even severe clinical manifestations that put patients at risk. On the other hand, the finding of hyperkalemia in a chronic context can lead to a reduction in dosages or to suspension of drugs such as angiotensin-converting enzymes inhibitor, angiotensin receptor blocker, angiotensin receptor neprilysin inhibitor, and mineralcorticoid receptor antagonist, first line in the treatment of the disease, with negative effects in prognostic terms. Therapies for the correction of hyperkalemia have so far mainly concerned the treatment of acute clinical pictures. Newly developed molecules, such as patiromer or sodium zirconium cyclosilicate, now open new prospectives in the long-term management of hyperkalemia, and allow us to glimpse the possibility of a better titration of the cardinal drugs for heart failure, with consequent positive effects on patient prognosis. The aim of this review is to focus on the problem of hyperkalemia in the setting of heart failure, with particular regard to its incidence, its prognostic role, and the underlining pathophysiological mechanisms. The review also provides an overview of therapeutic strategies for correcting hyperkalemia in acute and chronic conditions, with a focus on the new potassium binders that promise to improve management of heart failure., Competing Interests: The author declares no conflicts of interest., (© 2020 Minà et al.

Background: Identifying candidates for left ventricular assist device surgery at risk of right ventricular failure remains difficult. The aim was to identify the most accurate predictors of right ventricular failure among clinical, biological, and imaging markers, assessed by agreement of different supervised machine learning algorithms., Methods: Seventy-four patients, referred to HeartWare left ventricular assist device since 2010 in two Italian centers, were recruited. Biomarkers, right ventricular standard, and strain echocardiography, as well as cath-lab measures, were compared among patients who did not develop right ventricular failure (N = 56), those with acute-right ventricular failure (N = 8, 11%) or chronic-right ventricular failure (N = 10, 14%). Logistic regression, penalized logistic regression, linear support vector machines, and naïve Bayes algorithms with leave-one-out validation were used to evaluate the efficiency of any combination of three collected variables in an "all-subsets" approach., Results: Michigan risk score combined with central venous pressure assessed invasively and apical longitudinal systolic strain of the right ventricular-free wall were the most significant predictors of acute-right ventricular failure (maximum receiver operating characteristic-area under the curve = 0.95, 95% confidence interval = 0.91-1.00, by the naïve Bayes), while the right ventricular-free wall systolic strain of the middle segment, right atrial strain (QRS-synced), and tricuspid annular plane systolic excursion were the most significant predictors of Chronic-RVF (receiver operating characteristic-area under the curve = 0.97, 95% confidence interval = 0.91-1.00, according to naïve Bayes)., Conclusion: Apical right ventricular strain as well as right atrial strain provides complementary information, both critical to predict acute-right ventricular failure and chronic-right ventricular failure, respectively.

Background: Sacubitril/valsartan has been shown to be superior to enalapril in reducing the risks of death and hospitalization for heart failure (HF). However, knowledge of the impact on cardiac performance remains limited. We sought to evaluate the effects of sacubitril/valsartan on clinical, biochemical and echocardiographic parameters in patients with heart failure and reduced ejection fraction (HFrEF)., Methods: Sacubitril/valsartan was administered to 205 HFrEF patients., Results: Among 230 patients (mean age 59 ± 10 years, 46% with ischemic heart disease) 205 (89%) completed the study. After a follow-up of 10.49 (2.93 ± 18.44) months, the percentage of patients in New York Heart Association (NYHA) class III changed from 40% to 17% ( p < 0.001). Median N-Type natriuretic peptide (Nt-proBNP) decreased from 1865 ± 2318 to 1514 ± 2205 pg/mL, ( p = 0.01). Furosemide dose reduced from 131.3 ± 154.5 to 120 ± 142.5 ( p = 0.047). Ejection fraction (from 27± 5.9% to 30 ± 7.7% ( p < 0.001) and E/A ratio (from 1.67 ± 1.21 to 1.42 ± 1.12 ( p = 0.002)) improved. Moderate to severe mitral regurgitation (from 30.1% to 17.4%; p = 0.002) and tricuspid velocity decreased from 2.8 ± 0.55 m/sec to 2.64 ± 0.59 m/sec ( p < 0.014)., Conclusions: Sacubitril/valsartan induce "hemodynamic recovery" and, consistently with reduction in Nt-proBNP concentrations, improve NYHA class despite diuretic dose reduction., Competing Interests: The authors declare no conflict of interest.

Sudden cardiac death (SCD) is the most life-threating complication of hypertrophic cardiomyopathy. Guidelines of the European Society of Cardiology (ESC) suggest the implantation of an implantable cardioverter defibrillator in primary prevention according to a 5-year risk SCD score ≥6%. The aim of the study is to evaluate the prognostic role of late gadolinium enhancement (LGE) in patients with a 5-year risk SCD score <6%. In this multicenter study, we performed cardiac magnetic resonance in 354 consecutive hypertrophic cardiomyopathy patients (257 males, range of age 54 ± 17) with a risk SCD score <6% (302 with <4% and 52 with ≥4 and <6% risk). Hard cardiac events, including SCD, resuscitated cardiac arrest, appropriate implantable cardioverter defibrillator interventions, sustained ventricular tachycardia, occurred in 22 patients. LGE was detected in a high proportion (92%) of patients with hard cardiac events (p = 0.002). At receiver-operating characteristic curve analysis, LGE extent ≥10% was the best threshold to predict major arrhythmic events (area under the curve: 0.74). Kaplan-Meier curves showed that patients with LGE ≥10% had a worse prognosis than those with lower extent (p < 0.0001). LGE extent was the best independent predictor of hard cardiac events (hazard ratio 1.05; 95% confidence interval [CI] 1.03 to 107; p < 0.0001). The estimates 5-year risk of hard cardiac event was 2.5% (95% CI 0.8 to 4.2) in patients with LGE extent <10% and 23.4% (95% CI 10.2 to 36.5) for those with LGE extent ≥10%. In conclusion, this study demonstrates as the extent of LGE ≥10% is able to recognize additional patients at increased risk for malignant arrhythmic episodes in a population with low-to-intermediate ESC SCD risk score., (Copyright © 2019 Elsevier Inc.

Background: Risk stratification is a crucial issue in heart failure. Clinicians seek useful tools to tailor therapies according to patient risk., Methods: A prospective, observational, multicenter study on stable chronic heart failure outpatients with reduced left ventricular ejection fraction (HFrEF). Baseline demographics, blood, natriuretic peptides (NPs), high-sensitivity troponin I (hsTnI), and echocardiographic data, including the ratio between tricuspid annular plane excursion and systolic pulmonary artery pressure (TAPSE/PASP), were collected. Association with death for any cause was analyzed., Results: Four hundred thirty-one (431) consecutive patients were enrolled in the study. Fifty deaths occurred over a median follow-up of 32 months. On the multivariable Cox model analysis, TAPSE/PASP ratio, number of biomarkers above the threshold values, and gender were independent predictors of death. Both the TAPSE/PASP ratio ≥0.36 and TAPSE/PASP unavailable groups had a three-fold decrease in risk of death in comparison to the TAPSE/PASP ratio <0.36 group. The risk of death increased linearly by 1.6 for each additional positive biomarker and by almost two for women compared with men., Conclusions: In a HFrEF outpatient cohort, the evaluation of plasma levels of both NPs and hsTnI can contribute significantly to identifying patients who have a worse prognosis, in addition to the echocardiographic assessment of right ventricular-arterial coupling.

Hypertrophic obstructive cardiomyopathy (HOCM) is the most frequently inherited cardiovascular disease (prevalence in the general population of 1/500) and is characterized by significant left ventricular hypertrophy, especially in the interventricular septum, combined with small-volume cardiac cavities. Transaortic surgical septal myectomy is the most commonly used technique to treat HOCM, and is associated with low operative morbidity and mortality and a reduction of the outflow gradients. The composite operative mortality of only 0.4% (17/3695 patients) from 5 major high-volume centers in North America highlights the role of dedicated HOCM units. The involvement of the mitral valve in the pathophysiology of HOCM has been addressed as systolic anterior motion (SAM)-related left ventricular outflow tract obstruction. Hypertrophic cardiomyopathy mitral malformations include leaflet elongation and a wide array of malformations of the papillary muscles and chordae that can be detected by transthoracic and transesophageal echocardiography and by cardiac magnetic resonance. Because they participate fundamentally in the predisposition to SAM, they have increasingly been repaired surgically.

Introduction: Heart failure (HF) is a main issue of modern healthcare system. Patient affected are continuously growing in number and age; therefore, an integrated management between different parts of healthcare system is crucial to optimize outcome and sustainability. So far, little is known about clinical pathways of HF patients in Sicily., Methods: On initiative of the Regional HF Group of the Italian Association of Hospital Cardiologists (ANMCO), we decided to census all the Cardiology Unit of Sicily. A simple questionnaire elaborated by the group and exploring clinical and organizational matters of HF was sent to the Units. The answer arrived on a voluntary basis., Results: 41/46 Units sent back the filled questionnaire. Five typologies of units were represented, based on complexity [1. Outpatient units; 2. Units without Intensive Care Unit (ICU); 3. Units with ICU; 4. Units with ICU and Cath Lab; 5. Units with ICU, Cath lab and Cardiac Surgery). A dedicated HF unit is present only in half centers, but it is formally recognized solely in 22% of Units. These Units have scarce dedicated staff and activity is predominantly based on personal initiative. Diagnostic and therapeutic tools are used appropriately in most of them, even though congestion is judged mainly through physical exam and echocardiography. Differently from the indications of the guidelines, post discharge titration of therapy lacks in almost 30% of centers., Discussion and Conclusions: In Sicily, HF is managed on a plan mainly based on personal initiative. The quality is sufficiently good but a more appropriate and structured organization in particular of the follow-up seems a necessary and improvable requirement in view of quality measurers and economic sustainability of health care.

Heart failure (HF) with reduced ejection fraction (HFrEF) has a well-known epidemic relevance in western countries. It affects up to 1-2% of patients > 60 years and reaches a prevalence of 12% in octogenarian patients. The role of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitive troponin I (hsTnI) in risk stratifying HFrEF patients has been established; at present, evidence is exclusively based on one-time assessments, and the prognostic usefulness of serial biochemical assessments in this population still remains to be determined. We prospectively recruited 226 patients with chronic HFrEF, who were all referred to the Outpatient Clinic of our institution from November 2011 through September 2014. Recruited patients underwent full clinical evaluation with complete history taking and physical examination as well as ECG, biochemical assessment, and standard 2D and Doppler flow echocardiography at the first visit, and then again at each visit during the follow-up, repeated every 6 months. During the follow-up period, cardiovascular (CV) death, which occurred in 16 patients, was not statistically correlated with gender (p = 0.088) or age (p = 0.1636); however, baseline serum levels of NT-proBNP, which were 3 times higher in deceased patients, were significantly related to this clinical event (p = 0.001). We found that NT-proBNP represents a strong and independent predictor of CV outcome; serum levels of hsTnI, which are significantly related to an increased risk of hospitalization, cannot properly predict the relative risk of CV mortality. Our study validates, eventually, the multimarker strategy, which reflects the complexity of the HF pathophysiology., (© 2019 S. Karger AG, Basel.)

Use of continuous flow left ventricle assist device (CF-LVAD) in advanced heart failure (HF) patients results in clinically relevant improvements in survival, functional capacity, and quality of life. Peripheral artery disease (PAD) can occur in patients with CF-LVAD due to the high rate of concomitance between risk factors for atherosclerosis and HF. Diagnosis of PAD can be difficult in the specific setting of a patient supported by this kind of device because of the marked alteration in waveform morphology and velocity created by the artificial physiology of an LVAD. We report the case of a 53-year-old man with HF secondary to ischemic cardiomyopathy supported by the HeartWare HVAD as bridge to transplant, who after the implant developed symptoms suggestive of PAD. We describe additional computational flow analysis for the study of PAD-related hemodynamic disturbances induced by a CF-LVAD. Flow simulations enhance the information of clinical image data, and may have an application in clinical investigations of the risk of hemodynamic disturbances induced by LVAD implantation., (© 2018 International Center for Artificial Organs and Transplantation and Wiley Periodicals, Inc.)

Introduction: Peripheral neuropathy can affect patients with heart failure, though its prevalence is unknown. After heart transplantation, it can influence the postoperative course and quality of life, but screening for neuromuscular disease is not routinely performed., Objective: The aim of this study was to identify the factors associated with neuropathy in a population of patients with heart failure who are candidates for heart transplantation., Study Design: Data regarding patients' clinical history, including recent hospitalizations, were collected. All patients underwent a complete neurological examination and a neurophysiological protocol including nerve conduction studies and concentric needle electromyography., Results: Thirty-two patients were included in the study, and neuropathy was diagnosed in 10 (31.3%). Neuropathy was associated with the number of admissions ( P = .023; odds ratio [OR]: 1.96) and the total number of days of hospitalization in the year prior to inclusion in the study ( P = .010; OR: 1.03). The majority of hospitalizations occurred in the step-down unit (85%), with acute heart failure the leading cause of admission (42%)., Conclusions: This study shows that neuropathy is frequent in patients with advanced heart failure and that hospitalization for cardiac care, also in the absence of intensive care, is a marker of high risk of neurologic damage. These data can help physicians in selecting and managing candidates for transplantation and can guide decisions on the best immunosuppressive regimen or rehabilitation strategy.

Background: Primary graft dysfunction (P-GD) is the leading cause of early mortality after heart transplantation (HT). In this 2-center study we analyze outcomes and risk factors of P-GD according to the recent consensus conference classification endorsed by International Society for Heart and Lung Transplantation., Methods: We included all adult HTs performed between 1999 and 2013. P-GD was graded as mild, moderate, and severe, according to International Society for Heart and Lung Transplantation recommendations, and analyzed separately from secondary GD. The primary end point was the combined occurrence of in-hospital death or emergency retransplantation., Results: Early GD was found in 118 of 518 patients (23%), and 72 (13.9%) met the criteria for P-GD. Of these, 4 (5%) were mild, 33 (46%) moderate, and 35 (49%) severe and mostly characterized by biventricular involvement (78%). The end point occurred in 53 patients (10.2%). Overall, GD was a strong predictor of death-graft loss (odds ratio, 15.9; 95% confidence interval, 7.9-33.5; p < 0.01), with non-significant worse outcomes in P-GD (37%) vs secondary GD (27%) patients (p = 0.2). The study end point was more frequent in severe P-GD patients (65%) than in moderate (12%) or mild (0%; p < 0.01). Several known risk factors influenced the risk for P-GD, and the combination of specific donor and recipient risk factors accounted for approximately 22-times increased odds for P-GD. Donor age, recipient diabetes, ischemic time, and post-operative dialysis predicted non-recovery from P-GD., Conclusions: Consensus-defined P-GD identifies patients at major risk for early death and graft loss after HT, although the "mild" grade appeared under-represented and clinically irrelevant. The amplified negative effect of donor and recipient factors on P-GD risk underscores the need for appropriate donor-recipient match., (Copyright © 2017 International Society for the Heart and Lung Transplantation.

Cortical hubs play a fundamental role in the functional architecture of brain connectivity at rest. However, the anatomical scaffold underlying their centrality is still under debate. Certainly, the brain function and anatomy are significantly entwined through synaptogenesis and pruning mechanisms that continuously reshape structural and functional connections. Thus, if hubs are expected to exhibit a large number of direct anatomical connections with the rest of the brain, such a dense wiring is extremely inefficient in energetic terms. In this work, we investigate these aspects on fMRI and DTI data from a set of know resting-state networks, starting from the hypothesis that to promote integration, functional, and anatomical connections link different areas at different scales or hierarchies. Thus, we focused on the role of functional hubs in this hierarchical organization of functional and anatomical architectures. We found that these regions, from a structural point of view, are first linked to each other and successively to the rest of the brain. Thus, functionally central nodes seem to show few strong anatomical connections. These findings suggest an efficient strategy of the investigated cortical hubs in exploiting few direct anatomical connections to link functional hubs among each other that eventually reach the rest of the considered nodes through local indirect tracts.

Background: Heart transplantation (HTx) improves the quality of life and survival in patients affected by end-stage heart failure. The purpose of the current study is to present the patients' clinical data and results of HTx in a single Center of Sicily. Focus on survival after pre and post HTx mechanical circulatory support use will be performed., Methods: 133 HTx were done from 2004 to the end of 2015.The average donor age was 34±13.5years and the proportion of male donors was 67%. Percentage of use of mechanical circulatory support to bridge patients to HTx was 18%., Results: Overall pre-transplant mechanical circulatory support was not correlated to worse post-transplant prognosis, p=0.757. Severe primary early graft failure requiring extra corporeal membrane oxygenator support strongly impact the early mortality after heart transplantation (p<0.001)., Conclusions: The results of HTx at ISMETT are comparable to those reported in high volume Italian transplant centers as well as in the ISHLT registry. The favorable outcome can be related to focus on multidisciplinary approach, strict recipients' selection and young donor population. Post HTx mechanical circulatory support use in general remains associated with worse post-transplant outcomes. This does not apply to pre-op mechanical circulatory support population., (Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.)
