Abstract
Patent foramen ovale (PFO) is present in about one-quarter of the population and should be considered an anatomical variant rather than a malformation. The association of PFO with cryptogenic stroke, migraine, peripheral embolism and other pathologies is still controversial. The evaluation of anatomical complexity, and particularly the long-tunnel morphology, is crucial for the assessment of the risk profile and for a targeted therapeutic management. Long-tunnel PFOs seem to be more prone to clot formation and complications related to percutaneous closure procedures. Echocardiography is the most useful method to investigate anatomical complexity, confirm and reinforce the indication to treatment, select the appropriate device and guide the PFO closure towards a successful procedure.

Abstract
Background: Our study aimed to evaluate right ventricular (RV) morphology and strain (S) in the early stage of familial transthyretin (TTR) cardiac amyloidosis (CA). Methods and Results: Thirty-seven patients with transthyretin mutation underwent 99mTc-3,3-diphosphono-1,2 propanodicarboxylic acid (99mTc-DPD) scans and/or cardiac magnetic resonance (CMR) to identify TTR CA. Each patient underwent echocardiography to quantify RV dimensions, tricuspid annular plane systolic excursion (TAPSE), systolic pulmonary artery pressure (sPAP), longitudinal (L) strain of the RV free wall, left ventricular (LV) septal thickness (ST), ejection fraction, E/E', LV global (G) L, radial (R), and circumferential (C) S. 99mTc-DPD and CMR revealed the accumulation in 22 of 37 patients (CA group) and no accumulation in 15 patients (no-CA group). Left ventricular (LV) septal thickness (ST) was higher (P < 0.0001) while LV ejection fraction and E/E' were lower (P < 0.05) in the CA group than the no-CA group. LV-global longitudinal strain (LS) was lower (P < 0.0001) in the CA-group than the no CA-group, whereas LV-global circumferential strain and LV-global radial strain were similar. The CA group showed higher values of RV dimensions (P < 0.05) and sPAP (0.02) and a lower (P = 0.002) TAPSE. Globally, RV-LS was lower (P = 0.005) in the CA group than the no-CA group. Basal and mid segments of the RV free wall showed a lower LS in the CA group than the no-CA group (P < 0.01), while apical S was similar between groups. Conclusions: RV deformation, particularly in basal and mid segments, is early impaired in CA.

Abstract
Purpose: It is well known that anticancer drugs used for treating breast cancer can cause cardiac toxicity, and less is known about vascular toxicity. The aim of this study was to assess subclinical vascular effects of anthracyclines and trastuzumab (TRZ) in women treated for breast cancer. Methods: We enrolled 133 female patients with breast cancer undergoing adjuvant treatment with anthracycline-containing chemotherapy (CT) followed by taxane (paclitaxel/docetaxel) + TRZ. Patients underwent a standard echocardiography including measurement of left ventricular ejection fraction and global longitudinal strain at baseline and at follow-up. Vascular toxicity was evaluated by measuring brachial blood pressure (BP) and arterial stiffness indices (pulse wave velocity and Beta stiffness index) at T0 (baseline), T1 (3 months), T2 (6 months), and T3 (12 months). Results: Arterial stiffness indices were significantly increased at T1 in patients treated with anthracycline-containing CT (PWV 5.5 m/s IQR 5.15-6.4 at T0 vs. PWV 6.7 m/s IQR 5.6-7.2 at T1, p < 0.05; Beta index PWV 6.7 IQR 5.25-6.65 at T0, PWV 8.35 IQR 6.5-10.15 at T1, p < 0.05) but not at T2 and T3, when treatment with anthracyclines was stopped and patients were under treatment with taxane and TRZ. Blood pressure values did not significantly change during follow-up. Conclusion: Changes in arterial stiffness parameters occur early after starting treatment with anthracyclines, and they seem to be reversible if anthracycline treatment is stopped. These changes are not influenced by blood pressure values modifications. Therefore, in breast cancer women, anthracyclines seem to cause early reversible subclinical vascular injury.

Abstract
Takotsubo syndrome is found in about 5%-6% of patients presenting with suspected ST-elevation myocardial infarction. Coronary angiography with left ventriculography is currently considered the modality of choice for the diagnosis. However, improvements of noninvasive diagnostic techniques have been allowing for definite assessment of ventricular function and anatomy. In this setting, the combined use of coronary computed tomography angiography and cardiac magnetic resonance may play a pivotal role for a complete noninvasive diagnosis and management of these patients. We present a case of a 52-year-old woman who presented to our department complaining chest pain and showing left ventricular systolic dysfunction, electrocardiography abnormalities, and mild elevation of cardiac-specific serum enzymes.

Abstract
Objectives: To evaluate short- and long-term outcome in a single prospective cohort of Takotsubo syndrome (TTS) patients, trying to early identify those with better prognosis and to assess the prevalence of left ventricular ejection fraction (LVEF) recovery over time. Methods: Forty-nine patients prospectively enrolled underwent to assessment of demographic, clinical, and echocardiographic characteristics, and later were followed to identify the outcomes during a mean follow-up (FU) of 93 months. At the end of the FU phase, a subgroup of patients underwent to a clinical and echocardiographic re-evaluation. As major adverse cardiac events (MACE) were considered: Intra and extra-hospital death, re-hospitalizations for acute heart failure or atrial fibrillation (AF) or acute myocardial infarction (AMI) and TTS recurrence; minor events were considered minor symptoms of heart failure and angina not requiring hospitalization. Results: The prevalence of re-hospitalizations (MACE) over time was: 41% (n = 12) for HF; 6.8% (n = 2) for AMI; 3.4% (n = 1) for TTS relapse and 20% (n = 6) for AF. Minor events were the symptoms of chest pain and dyspnea not requiring hospitalization in 6 (20.7%) and 12 (34.4%) patients, respectively. LVEF at the time of admission was predictor for MACE. Stratifying patients on the LVEF admission median value (40%). Patients with LVEF <40% at admission had a significantly lower survival free from adverse cardiac events compared to patients with LVEF ≥40%. Twenty-seven (93%) patients underwent to a clinical reassessment with electrocardiogram and echocardiographic examination. LVEF value showed a statistically significant increase (P = 0.004) at the end of FU. Conclusions: At admission, “high-risk” patients (LVEF <40%) can be easily detected, allowing an appropriate pharmacological and/or mechanical support strategy and a more “careful” FU.

Abstract
Duchenne muscular dystrophy (DMD) is complicated by an early and progressive left ventricular (LV) dysfunction. Despite the reduction of ejection fraction (EF) usually manifests in the second decade, subtle alterations in LV mechanics can be detected earlier. Longitudinal and circumferential LV deformation, evaluated by speckle tracking echocardiography (STE), are considered sensitive markers of early dysfunction. We retrospectively examined clinical and echocardiographic data of 32 DMD children with preserved LV function. According to the median age, patients were then divided into younger and older than 9 years, and compared to 24 age-matched healthy subjects. Six-minute-walk test (6MWT), North Star Ambulatory Assessment (NSAA), and a comprehensive cardiac evaluation were performed. Although EF was within the normal range, DMD patients had significantly lower values than healthy controls, and the same occurred for the remaining conventional systolic and diastolic indices. Global longitudinal strain (GLS) was reduced in all patients (older and younger, both p < 0.001). Global circumferential strain (GCS) was reduced only in older patients (< 0.001). Both GLS and GCS worsened with age in DMD patients (GLS p = 0.005; GCS p = 0.024). GLS was significantly worse in the apical segments and in the postero-lateral wall. GCS in the antero-septal, anterior and antero-lateral segments was significantly reduced in older patients, with a prevalent involvement of the sole septal wall in the younger boys. 6MWT appeared to be correlated inversely to GLS and directly to EF. A longitudinal evaluation should be scheduled in DMD boys to assess the global cardiac performance over time and to evaluate the impact of therapies.

Abstract
Pulmonary hypertension (PH) is a hemodynamic condition characterized by chronically elevated mean pulmonary artery pressure (m-PAP ≥ 25 mmHg) measured at rest by right heart catheterization (RHC). It includes a pre-capillary and a post-capillary form. Pulmonary artery hypertension (PAH) is a pre-capillary form of PH potentially generated by several heterogeneous systemic disorders, whose main hemodynamic change is represented by severely increased pulmonary vascular resistance (PVR). In order to preserve an efficient right ventricular-arterial (RV-PA) coupling, the right ventricle (RV) adapts to this chronic increase of its afterload, with a compensatory hypertrophy, until RV dilatation and dysfunction occur. Right ventricular (RV) function and especially RV-PA coupling assessment showed to be very important prognostic markers in this subset of patients, especially for those with pre-capillary PH. The aim of this review is to provide a pathophysiological insight into the spectrum of RV adaptive changes occurring in response to chronic increase of RV afterload and to present the role of echocardiographic parameters as possible tools for early non-invasive evaluation of RV-PA coupling, before overt heart failure ensues.

Abstract
Background Low-gradient aortic stenosis (LG-AS) is characterized by the combination of an aortic valve area compatible with severe stenosis and a low transvalvular mean gradient with low-flow state (i.e., indexed stroke volume <35 mL/m2) in the presence of reduced (classical low-flow AS) or preserved (paradoxical low-flow AS) ejection fraction. Furthermore, the occurrence of a normal-flow LG-AS is still advocated by many authors. Within this diagnostic complexity, the diagnosis of severe AS remains challenging. Objective The general objective of the Discordant Echocardiographic Grading in Low-gradient AS (DEGAS Study) study will be to assess the prevalence of true severe AS in this population and validate new parameters to improve the assessment and the clinical decision-making in patients with LG-AS. Methods and Analyses The DEGAS Study of the Italian Society of Echocardiography and Cardiovascular Imaging is a prospective, multicenter, observational diagnostic study that will enroll consecutively adult patients with LG-AS over 2 years. AS severity will be ideally confirmed by a multimodality approach, but only the quantification of calcium score by multidetector computed tomography will be mandatory. The primary clinical outcome variable will be 12-month all-cause mortality. The secondary outcome variables will be (i) 30-day mortality (for patients treated by Surgical aortic valve replacement or TAVR); (ii) 12-month cardiovascular mortality; (iii) 12-month new major cardiovascular events such as myocardial infarction, stroke, vascular complications, and rehospitalization for heart failure; and (iv) composite endpoint of cardiovascular mortality and hospitalization for heart failure. Data collection will take place through a web platform (REDCap), absolutely secure based on current standards concerning the ethical requirements and data integrity.

Abstract
AIMS To obtain the normal ranges for 2D echocardiographic (2DE) indices of myocardial work (MW) from a large group of healthy volunteers over a wide range of ages and gender. METHODS AND RESULTS A total of 226 (85 men, mean age: 45 ± 13 years) healthy subjects were enrolled at 22 collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study. Global work index (GWI), global constructive work (GCW), global work waste (GWW), and global work efficiency (GWE) were estimated from left ventricle (LV) pressure-strain loops. Peak LV systolic pressure was non-invasively derived from brachial artery cuff pressure. The lowest values of MW indices in men and women were 1270 mmHg% and 1310 mmHg% for GWI, 1650 mmHg% and 1544 mmHg% for GCW, and 90% and 91% for GWE, respectively. The highest value for GWW was 238 mmHg% in men and 239 mmHg% in women. Men had significant lower values of GWE and higher values of GWW. GWI and GCW significantly increased with age in women. CONCLUSION The NORRE study provides useful 2DE reference ranges for novel indices of non-invasive MW.

Abstract
Metabolic syndrome (MetS) is a well established risk factor for cardiovascular (CV) diseases. In addition, several studies indicate that MetS correlates with the increased risk of cancer in adults. The mechanisms linking MetS and cancer are not fully understood. Several risk factors involved in MetS are also cancer risk factors, such as the consumption of high calorie-food or high fat intake, low fibre intake, and sedentary lifestyle. Other common aspects of both cancer and MetS are oxidative stress and inflammation. In addition, some anticancer treatments can induce cardiotoxicity, including, for instance, left ventricular (LV) dysfunction and heart failure (HF), endothelial dysfunction and hypertension. In this review, we analyse several aspects of MetS, cancer and cardiotoxicity from anticancer drugs. In particular, we focus on oxidative stress in ageing, cancer and CV diseases, and we analyse the connections among CV risk factors, cancer and cardiotoxicity from anticancer drugs.

Abstract
Anthracyclines are the cornerstone for many oncologic treatments, but their cardiotoxicity has been recognized for several decades. Female subjects, especially before puberty and adolescence, or after menopause, seem to be more at increased risk, with the prognostic impact of this sex issue being less consistent compared to other cardiovascular risk factors. Several studies imply that sex differences could depend on the lack of the protective effect of sex hormones against the anthracycline-initiated damage in cardiac cells, or on differential mitochondria-related oxidative gene expression. This is also reflected by the results obtained with different diagnostic methods, such as cardiovascular biomarkers and imaging techniques (echocardiography, magnetic resonance, and nuclear medicine) in the diagnosis and monitoring of cardiotoxicity, confirming that sex differences exist. The same is true about protective strategies from anthracycline cardiotoxicity. Indeed, first studied to withstand oxidative damage in response to ischemia/reperfusion (I/R) injury, cardioprotection has different outcomes in men and women. A number of studies assessed the differences in I/R response between male and female hearts, with oxidative stress and apoptosis being shared mechanisms between the I/R and anthracyclines heart damage. Sex hormones can modulate these mechanisms, thus confirming their importance in the pathophysiology in cardioprotection not only from the ischemia/reperfusion damage, but also from anthracyclines, fueling further cardio-oncologic research on the topic.

Abstract
Peripheral artery disease (PAD) and stroke can occur as vascular complication of anticancer treatment. Although the mechanisms, monitoring, and management of cardiotoxicities have received broad attention, vascular toxicities remain often underrecognized. In addition, the development of new chemotherapeutic drugs bears the risk of vasotoxicities that are yet to be identified and may not be realized with short-term follow-up periods. The propensity to develop PAD and/or stroke reflects the complex interplay between patient's baseline risk and preexisting vascular disease, particularly hypertension and diabetes, while evidence for genetic predisposition is increasing. Chemotherapeutic agents with a prominent vascular side effect profile have been identified. Interruption of vascular endothelial growth factor (VEGF) inhibitors (VEGFIs) signaling (i.e., bevacizumab) is associated with vascular toxicity and clinical sequelae such as hypertension, stroke, and thromboembolism beyond acute coronary syndromes. Cisplatin and 5-fluorouracil are the main drugs involved in the stroke risk. In addition, circulating concentrations of VEGF are reduced by cyclophosphamide administered at continuous low doses, which might underpin some of the observed vascular toxicity, such as stroke, as seen in patients treated with VEGF inhibitors. The risk of stroke is also increased after treatment with anthracyclines that can induce endothelial dysfunction and increase arterial stiffness. Proteasome inhibitors ( bortezomib and carfilzomib) and immunomodulatory agents (thalidomide, lenalidomide, and pomalidomide), approved for use in multiple myeloma, carry a black box warning for an increased risk of stroke. Finally, head-and-neck radiotherapy is associated with a doubled risk of cerebrovascular ischemic event, especially if exposure occurs in childhood. The mechanisms involved in radiation vasculopathy are represented by endothelial dysfunction, medial necrosis, fibrosis, and accelerated atherosclerosis. However, BCR-ABL tyrosine kinase inhibitor (TKI), used for the treatment of chronic myeloid leukemia (CML), is the main antineoplastic drugs involved in the development of PAD. In particular, second- and third-generation TKIs, such as nilotinib and ponatinib, while emerging as a potent arm in contrasting CML, are associated with a higher risk of PAD development rather than traditional imatinib. Factors favoring vascular complication are the presence of traditional cardiovascular risk factors (CVRF) and predisposing genetic factors, high doses of BCR-ABL TKIs, longer time of drug exposure, and sequential use of potent TKIs. Therefore, accurate cardiovascular risk stratification is strongly recommended in patient candidate to anticancer treatment associated with higher risk of vascular complication, in order to reduce the incidence of PAD and stroke through CVRF correction and selection of appropriate tailored patient strategy of treatment. Then, a clinical follow-up, eventually associated with instrumental evaluation through vascular ultrasound, should be performed.

Abstract
Abstract
Background
Myocardial Work (MW) is an interesting novel non-invasive parameter to evaluate cardiac performance by left ventricle (LV) pressure-strain loops.
Purpose
The present study sought to investigate MW in patients with both non-obstructive (NOHCM) and obstructive hypertrophic cardiomyopathy (OHCM).
Methods
Forty-four patients with hypertrophic cardiomyopathy (HCM) and twenty controls (mean age 53 ± 20 years vs 52 ± 17 years, respectively, p = 0.8) underwent standard two-dimensional and speckle-tracking echocardiography. Global Work Index (GWI), global constructive work (GCW), global work waste (GWW) and global work efficiency (GWE) were estimated by LV pressure-strain loops. In OHCM group, MW was evaluated by adding LVOT peak gradient to SBP. Analysis of multilayer LV longitudinal strain (LS) and left atrial (LA) LS was performed.
Results
Global LS (GLS), endocardial LS, epicardial LS and LA LS were significantly reduced in patients compared to controls (p < 0.001 for all). All patient population had significantly lower GWI, GCW and GWE and higher GWW respect to controls. Regional GLS, endocardial LS, epicardial LS and regional WI were significantly reduced in hypertrophic area compared to no-hypertrophic area in the patient population (p < 0.001 for all). OHCM group ( n = 14) had higher values of GWI and GCW compared to NOHCM ( n = 30) (2160 (1877-2250) vs 1547 (1148-1767)mmHg% and 2285 ± 411 vs 1755 ± 584 mmHg% respectively, p < 0.05 for both, Figure).
Conclusions
GWI and GCW are reduced in patients with NOHCM. Patients with OHCM, have higher GWI and GCW compared to non-obstructive ones, as expression of work at higher level of energy necessary to counteract high afterload. Our proposed method to estimate MW in OHCM needs to be validated in invasive studies.

Abstract
Abstract
Purpose
To confirm GLS diagnostic sensitivity as parameter for the evaluation of LV systolic function in women with breast cancer who underwent chemotherapy including anthracyclines and to identify a pattern of decreased 2D speckle tracking regional longitudinal strain through the analysis of polar maps obtained with AFI technology.
Methods
We enrolled 60 female patients (age with 56.5±12 years) with breast cancer before the beginning of chemotherapy. The study protocol included clinical examination, ECG with QTc calculation, lab test (BNP and troponin I) and echocardiography with TDI and speckle tracking analysis (STI), that were performed before the beginning of the chemotherapy (basal) and after 3, 6 and 12 months. Echocardiography evaluation included the following parameters: LV end-diastolic and end-systolic volumes, LV ejection fraction (EF), average TDI S' at the mitral annulus, Global Longitudinal Strain (GLS), regional longitudinal strain, E/A ratio, E/E' ratio and sPAP. For each patient we analyzed the bull's eye maps before the beginning of the therapy (basal value) and when GLS showed the lowest values during the FU (FU value), to identify the pattern of regional longitudinal strain alterations. We compared basal and FU strain values for each of the 17 LV segments and the difference between them (delta) was calculated according to the formula [(FU LS –basal LS, (%)].
Results
During the FU, systolic blood pressure, systolic pulse pressure and BNP values increased from the basal assessment to the 3 and 6 months FU. Similarly, a progressive worsening of GLS values has been observed (basal −20.4±2.6%, 3 months FU −18.2±2.5%, 6 months FU −17.7±2.9, 12 months FU −17.6±3, p value <0.001). Through the analysis of polar maps, we observed that regional strain values worsened significantly in all the LV segments but the most evident impairment was reported in the apical cap (−22.8±3.9 vs −17.1±3.8; p<0.001, Δ=−5,78%) and in the apical segment of the anterior interventricular septum (−23.4±4.5 vs −17±6.3; p<0.001, Δ=−6,2%), as reported in Figure.
Conclusion
GLS is able to identify LV systolic dysfunction that EF is not able to detect. However, since that it describes the global function of LV, GLS could result as normal (18–20%) when strain impairment of some LV segments is counterbalanced by the compensatory strain increase of other segments, determining an misdiagnosis of myocardial damage. Regional strain and particularly the Δ-strain, seem to suggest that anthracyclines induce a damage more evident in the apical cap and in the apical segment of the interventricular septum and this pattern could be typical in these patients. Thus, polar maps analysis could be provide additional information about cardiac damage in this population.

Abstract
Abstract
Background
Although generally considered a benign disease, Takotsubo syndrome (TTS) has recently been associated to a substantially comparable long-term outcome than acute coronary syndrome (ACS). The use of beta-blockers (BB) has been advocated in these patients for secondary prevention after the index event, considering the presumed role of catecholamine in TTS pathophysiology. However, the effect of BB on long-term outcome remains controversial due to the paucity of data and the lack of evidence from randomized studies.
Purpose
To investigate the impact of BB therapy on long-term outcome in patients with TTS.
Methods
The study included all TTS patients enrolled in the Takotsubo Italian Network multicenter registry. Patients were divided in two study groups according to the BB therapy after discharge. The following major adverse cardiac events (MACE) were assessed at the longest available follow-up: cardiac death, TTS recurrence, rehospitalization for cardiac cause, acute or worsening heart failure (HF) and ACS. Also, the composite of cardiac death and rehospitalization as well as the overall MACE were analyzed
Results
The study population included 548 patients (mean age 68.7±11.4 years; 44 males, 8%). Among them, BB treatment was reported in 368 (BB group, 67.2%) and 180 (no-BB group, 32.8%) patients, respectively. The baseline clinical characteristics were substantially comparable among groups with the only exception of COPD, which was prevalent in the no-BB group (10.3% vs 21.7%, p=0.001).
During follow-up (median 18 months 25–75% c.i. 6–29), TTS recurrence was reported in 26 patients (4.7%), ACS in 10 (1.8%), acute or worsening HF in 39 (7.1%), cardiac hospitalization in 71 (13.0%) and cardiac death in 18 (3.3%). The rate of TTS recurrence and ACS was comparable between groups. Conversely, no-BB patients experienced more frequently acute or worsening HF (5.4% vs 10.6%, p=0.034), cardiac rehospitalization (10.9% vs 17.2%, p=0.042) and cardiac death (1.9% vs 6.1, p=0.018) than BB patients. Therefore, the MACE composite endpoint was significantly prevalent in the no-BB group (12.0% vs 20.6%, p=0.010).
Kaplan-Meier curves for the composite of cardiac death and rehospitalization showed a statistically lower survival in the no-BB patients compared to the BB group (p=0.006). Moreover, landmark analysis showed a wider survival benefit in the BB patients after 2 years.
Conclusions
Although in absence of a secondary preventive effect on TTS recurrence, BB may improve the long-term cardiac outcome in patients with TTS. Prospective randomized studies are advisable to confirm these findings.

Abstract
Abstract
Background
Myocardial work (MW) is a parameter of myocardial function which takes into account deformation as well as afterload. LV pressure-strain loops (PSLs) are a novel and reliable tool for the non-invasive assessment of MW.
Purpose
To evaluate MW indices in ischemic heart disease and their changes according to ejection fraction (EF) and type of myocardial infarction (MI) namely no-ST-segment elevation MI (NSTEMI) or ST-segment elevation MI (STEMI).
Methods
A total of 61 patients (mean age: 64.4±12 years) since at least 30 days from acute STEMI or NSTEMI treated with primary PTCA and 31 healthy subjects (controls) were enrolled. Patients with MI were divided into three groups according to the EF-based heart failure (HF) classification: a) group 1, HF preserved EF (HFpEF, EF >50%); 2) group 2, HF mid-range EF (HFmrEF, EF 40–49%); 3) group 3, HF reduced EF (HFrEF, EF <40%). Global Work Index (GWI), Global Constructive Work (GCW), Global Work Waste (GWW) and Global Work Efficiency (GWE), were estimated by LV PSLs using custom software.
Results
As shown in Table 1, GWE was significantly reduced in HFmrEF and HFrEF group (p=0.001) compared to both the controls and HFpEF group, while GWW was significantly higher (p<0.001) in the HFmEF group compared to controls and in the HFrEF group (p<0.001) vs all the other groups. GWI mmHg and GCW mmHg showed significantly compromised values in patients of HFmrEF and HFrEF groups compared to patients in HFpEF group and controls (p=0.001 and p<0.001 respectively). NSTEMI patients showed higher values of GCW compared to STEMI patients (p=0.003), and a trend towards better values of GWI, although not statistical significant. No significant differences were found about GWE and GWW. A strong correlation was found between indices of MW and LV volumes and EF (Table 2)
Conclusions
The non-invasive MW indices show a good correlation with traditional 2D parameters of myocardial systolic function in patients with ischemic heart disease. In addition, STEMI patients have lower constructive work than those with previous NSTEMI.

Abstract
The intensive care unit (ICU) is among the more important settings in which echocardiography plays a pivotal role. The ease of use, speed of execution, and completeness of information on heart anatomy and function that echocardiography is able to provide makes this tool the perfect diagnostic technique in patients for whom exhaustive information must be quickly obtained by physicians who sometimes lack specific skills in cardiovascular imaging. However, the clinical entities encountered by ICU clinicians are often difficult to distinguish and patient symptoms may not be obvious. This brief review describes three common clinical scenarios that benefit from echocardiography in the ICU, based on symptoms frequently claimed by patients admitted to the ICU. For each symptom we describe the most likely clinical possibilities, underlining the fundamental role that echocardiography plays in the differential diagnosis, and the echocardiographic elements most relevant to obtain the correct diagnosis and to guide treatment.

Abstract
We report a rare case of iatrogenic right coronary artery (RCA) dissection complicated by a retrograde subtle aortic dissection, which occurred during a primary percutaneous transluminal coronary angioplasty (PTCA). A 65-year-old female, with acute anterior ST-elevation myocardial infarction (STEMI), promptly underwent primary PTCA in the left anterior descending artery. After 5 h, the patient's condition becomes worse with recurrence of chest pain and new electrocardiogram modifications suggestive of inferior STEMI. A second coronary angiography revealed a spiral dissection extending from the ostium to the medium tract of the RCA. At the same time, a contrast media extravasation due to coronary ostium fissure occurred. Coronary stents were implanted from the medium tract of the right coronary to the ostium, to promptly arrest the active bleeding and to treat the dissection. After cardiosurgical advice, the patient was referred to the radiology department, where she underwent computed tomography angiography (CTA), which showed a small hematoma in the anterior wall of the ascending aorta. The stable clinical conditions of the patient suggested a conservative therapeutic approach. During the following 6 weeks CTA and transesophageal echocardiography were performed to rule out any other complication, and the patient was fortunately discharged with almost complete resolution of the hematoma.

Abstract
Significance: Antineoplastic therapies have significantly improved the prognosis of oncology patients. However, these treatments can bring to a higher incidence of side-effects, including the worrying cardiovascular toxicity (CTX). Recent Advances: Substantial evidence indicates multiple mechanisms of CTX, with redox mechanisms playing a key role. Recent data singled out mitochondria as key targets for antineoplastic drug-induced CTX; understanding the underlying mechanisms is, therefore, crucial for effective cardioprotection, without compromising the efficacy of anti-cancer treatments. Critical Issues: CTX can occur within a few days or many years after treatment. Type I CTX is associated with irreversible cardiac cell injury, and it is typically caused by anthracyclines and traditional chemotherapeutics. Type II CTX is generally caused by novel biologics and more targeted drugs, and it is associated with reversible myocardial dysfunction. Therefore, patients undergoing anti-cancer treatments should be closely monitored, and patients at risk of CTX should be identified before beginning treatment to reduce CTX-related morbidity. Future Directions: Genetic profiling of clinical risk factors and an integrated approach using molecular, imaging, and clinical data may allow the recognition of patients who are at a high risk of developing chemotherapy-related CTX, and it may suggest methodologies to limit damage in a wider range of patients. The involvement of redox mechanisms in cancer biology and anticancer treatments is a very active field of research. Further investigations will be necessary to uncover the hallmarks of cancer from a redox perspective and to develop more efficacious antineoplastic therapies that also spare the cardiovascular system.

Abstract
Aims Bicuspid aortic valve (BAV) is associated with aortic wall alterations. We aimed to detect any correlation between aortic elasticity and genetic and biomolecular patterns of elastin. Methods and results Forty-nine BAV patients (mean age: 38 ± 17.05) were prospectively enrolled. A blood sample was drawn for analysis of a single nucleotide polymorphism of elastin gene (ELN rs2071307) responsible for misfolding of elastin, and for the amount of elastin soluble fragments (ESF) in the plasma. Aortic dimensions and elastic properties were determined by echocardiography, aortic stiffness (AS) by M-mode analysis, and longitudinal strain (LS) of the ascending aorta (AA) by speckle-tracking echocardiography; values of aortic strain were compared with 45 age-matched subjects (mean age: 33 ± 9.67) with tricuspid aortic valve (TAV). BAV patients had greater aortic dimensions [Valsalva sinus (P = 0.004), sinotubular junction (P = 0.013), AA (P < 0.001)] and stiffness (P = 0.002) but lower LS (P = 0.04) than those with TAV. Results from comparisons of mutated genotype patients (AA, n = 10) with heterozygous (GA, n = 21) and wild-types ones (GG, n = 16) revealed that the presence of mutation was associated with increased ESF (P = 0.010 GG vs. GA; P = 0.035 GA vs. AA), larger AA (P = 0.019 GG vs. GA; P = 0.001 GG vs. AA), and lower LS (P = 0.032 GG vs. AA). Patients with a dilated AA showed greater ESF (P < 0.001), greater AS (P = 0.007), and lower LS of the AA (P = 0.002) than those with a normal AA. The same parameters were not significantly different comparing patients with moderate or severe aortic valve disease and patients with less than moderate valve disease. Conclusions Our results show a close correlation between genetic and biomolecular patterns of elastin and mechanical properties of the aorta in patients with BAV.

Abstract
Serum uric acid (UA) has been shown to be a predictor of cardiovascular (CV) morbidity and mortality, and it may play a role in the pathogenesis of CV disease affecting vascular structure and function. However, there is limited evidence of its specific association with carotid artery stiffness and structure. The aim of our study was to evaluate whether UA is associated with early signs of atherosclerosis, namely local carotid arterial stiffness and intima-media thickening. We evaluated 698 consecutive asymptomatic patients, referred to the Cardiovascular Department for risk factors evaluation and treatment. All patients underwent carotid artery ultrasonography with measurement of common carotid intima-media thickness (IMT) and echo-tracking carotid artery stiffness index Beta. Patients with hyperuricemia (defined as serum uric acid ≥7 mg/dL in men and ≥6 mg/dL in women) had higher IMT (0.97±0.22 vs 0.91±0.18, p<0.001) and stiffness index Beta (8.3±3.2 vs 7.5±2.7, p=0.005). UA levels correlated with both IMT (r=0.225; p<0.001) and stiffness index Beta (r=0.154; p<0.001); the correlations were statistically significant in males and females. In a multivariate model which included age, arterial pressure, serum glucose and LDL-cholesterol, serum UA emerged as an independent explanatory variable of IMT and stiffness index Beta. Carotid IMT and local arterial stiffness are related to UA independently of established CV risk factors; UA may play a role in the early development of atherosclerosis.

Abstract
AIM To evaluate the long-term outcome of patients with Takotsubo syndrome (TTS) and severely reduced left ventricular ejection fraction (LVEF ≤ 35%) at presentation. METHODS AND RESULTS The study population included 326 patients (mean age 69.5 ± 10.7 years, 28 male) with TTS enrolled in the Takotsubo Italian Network, divided into two groups according to LVEF (≤ 35%, n = 131; > 35%, n = 195), as assessed by transthoracic echocardiography at hospital admission. In-hospital events were recorded in both groups. At long-term follow-up (median 26.5 months, interquartile range 18-33), composite major adverse cardiac events (MACE: cardiac death, acute myocardial infarction, heart failure, and TTS recurrence) and rehospitalization were investigated. Compared to patients with LVEF > 35%, patients with LVEF ≤ 35% were older (71.2 ± 10.8 vs. 68.4 ± 10.6 years; P = 0.026) and experienced more frequently cardiogenic shock (16% vs. 4.6%; P < 0.001), acute heart failure (28.2% vs. 12.8%; P = 0.001), and intra-aortic balloon pump support (11.5% vs. 2.6%; P = 0.001) in the acute phase. At long-term follow-up, higher rates of composite MACE (25.2% vs. 10.8%; P = 0.001) and rehospitalization for cardiac causes (26% vs. 13.3%; P = 0.004) were observed in these patients. LVEF ≤ 35% at admission [hazard ratio (HR) 2.184, 95% confidence interval (CI) 1.231-3.872; P = 0.008] and age (HR 1.041, 95% CI 1.011-1.073; P = 0.006) were independent predictors of MACE. Patients with LVEF ≤ 35% also had a significant lower freedom from composite MACE during long-term follow-up (χ2 = 11.551, P = 0.001). CONCLUSION Left ventricular ejection fraction ≤ 35% at presentation is a key parameter to identify TTS patients at higher risk not only in the acute phase but also at long-term follow-up.
