In patients with suspected or established hypertrophic cardiomyopathy (HCM), cardiovascular magnetic resonance (CMR) is widely employed for clinical management, given its multimodality approach capable of providing unique information on cardiac morphology, function, and tissue characterization. Guidance regarding all aspects of HCM diagnosis and management is provided by the comprehensive 2014 European Society of Cardiology (ESC) guidelines on HCM. CMR should be performed in centres with recognized expertise in heart muscle diseases, by physicians who are familiar with the whole HCM disease spectrum, differential diagnoses, and pitfalls.

Previous reports have suggested that despite their dramatic presentation, patients with fulminant myocarditis (FM) might have better outcome than those with acute nonfulminant myocarditis (NFM). In this retrospective study, we report outcome and changes in left ventricular ejection fraction (LVEF) in a large cohort of patients with FM compared with patients with NFM.
The study population consists of 187 consecutive patients admitted between May 2001 and November 2016 with a diagnosis of acute myocarditis (onset of symptoms <1 month) of whom 55 required inotropes and/or mechanical circulatory support (FM) and the remaining 132 were hemodynamically stable (NFM).

Traditional echocardiography is unable to detect neither the early stages of iron overload cardiomyopathy nor myocardial iron deposition. The aim of the study is to determine myocardial systolic strain indices in thalassemia major (TM), and assess their relationship with T2*, a cardiac magnetic resonance index of the severity of cardiac iron overload. 55 TM cases with recent cardiac magnetic resonance (CMR-T2*) underwent speckle tracking analysis to assess regional myocardial strains and rotation.

Pheochromocytoma is a rare tumor, usually benign, potentially lethal in case of crisis with acute release of catecholamines. The heart is a target and the clinical presentation can mimic various cardiac conditions, thus rendering diagnosis elusive. Cardiac magnetic resonance is a valuable non-invasive diagnostic tool for the evaluation of cardiomyopathies; it allows the identification of catecholamine-induced myocarditis pattern and, in some cases, it can detect the primary tumor.

The presence of late gadolinium enhancement (LGE) at cardiac magnetic resonance (CMR) has diagnostic and prognostic value in patients with acute myocarditis (AM). Aim of our study was to quantify the changes in LGE extension (LGE%) early after AM and evaluate its relations with biventricular function and morphology.
We investigated 76 consecutive patients with AM (acute onset of chest pain/heart failure/ventricular arrhythmias not explained by other causes, and raised troponin) that met CMR criteria based on myocardial oedema at T2-weighted images and LGE on post-contrast images at median time of 6days from onset of symptoms.

Although pulmonary function abnormalities in thalassaemia major (TM) were described in 1980, the pathogenetic mechanism is not clear and data are contradictory, probably because of study heterogeneity and the multifactorial nature of the pathogenesis. We retrospectively analysed 73 adult TM patients to evaluate the prevalence of pulmonary dysfunction in adult TM and investigate relationships with iron load. All patients underwent body plethysmography and carbon monoxide diffusion (DLCO) was assessed in 63, in addition to blood tests, echocardiogram and T2* myocardial and liver magnetic resonance imaging.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a systemic necrotizing vasculitis characterized by hypereosinophilia. EGPA typically develops in three clinical phases, beginning with asthma, followed by tissue eosinophilia and finally systemic vasculitis. Cardiac involvement is the most important predictor of mortality; it occurs in approximately 15-60% of EGPA patients, a significant proportion of whom are asymptomatic and have normal electrocardiogram (ECG) and echocardiogram.

: Necrotizing eosinophilic myocarditis (NEM) is a life-threatening condition that needs rapid diagnosis by endomyocardial biopsy and hemodynamic support usually by mechanical circulatory systems. We present the case of a 25-year-old Caucasian man who developed a refractory cardiogenic shock due to a NEM that was supported with a peripheral veno-arterial extracorporeal membrane oxygenation associated with intravenous steroids and recovered after 2 weeks. Further instrumental investigations lead to the final diagnosis of NEM as first presentation of eosinophilic granulomatosis with polyangiitis (formerly Churg-Strauss syndrome), remarking the importance of identifying the systemic disorder that usually triggers the eosinophilic damage of the myocardium.

Hereditary hemochromatosis, thalassemia and myelodysplastic syndromes represent disease models with evidence of iron-related heart failure. Non-Transferrin Bound Iron (NTBI) induces cardiac toxicity through the production of reactive oxygen species and lipid peroxidation. In ST-elevation acute myocardial infarction (STEMI) with evidence of microvascular obstruction (MVO) and hemorrhage (HEM), HEM may be a source of iron-related cardiac toxicity through NTBI and pro-inflammatory mediators.

Coronary artery disease is a rare entity in young patients and accurate assessment of its prevalence is difficult. Although coronary artery disease is frequently a silent process, it may also acutely present with myocardial infarction (MI). One of the most feared complications of MI is left ventricular thrombus formation.

Ventricular aneurysm as late complication has been described in cardiac sarcoidosis and occasionally in giant cell myocarditis. The images from the present case of ventricular aneurysm formation as a late complication of giant cell myocarditis underline a potential cause of sudden arrhythmic death in patients who survive this life-threatening condition in the absence of recurrent inflammation and with preserved left ventricular ejection fraction. Follow-up with cardiac magnetic resonance can detect small aneurysms, and an implantable cardioverter-defibrillator may be considered when this complication occurs.

We report the description of a cardiac mass occupying almost the entire right atrium in a young man who developed paroxysmal supraventricular tachycardia during endovascular treatment of intracranial arteriovenous fistulas. The mass was detected at echocardiographic examination, its tissue characteristics were defined with cardiac magnetic resonance and it was successfully surgically removed. The histopathological findings were consistent with a mixed type cavernous-capillary hemangioma of the heart.

We report the histopathologic correlates of late gadolinium enhancement (LGE) at cardiac magnetic resonance (CMR) in a patient with heart transplant who died for graft failure a few months after the scan. Extensive late enhancement was present at CMR, and it correlated with extensive fibrosis at histology. To our knowledge, this is the first time the findings on contrast enhancement CMR are compared to the histology of the whole heart in a heart transplantation patient, and the correspondence between LGE and fibrosis, demonstrated in other cardiac pathologies, is confirmed also in this particular setting.

: A 31-year-old man presenting with cardiogenic shock and left ventricular ejection fraction of 10% received the diagnosis of giant cell myocarditis by endomyocardial biopsy. The patient was successfully treated with high-dose inotropes, intra-aortic balloon pump and venoarterial extracorporeal membrane oxygenation for 21 days associated with combined immunosuppression (thymoglobulin, steroids, cyclosporine). Immunosuppression including thymoglobulin is the regimen associated with the highest probability of recovery in case of giant cell myocarditis.

The role of the right ventricle has often been underestimated in heart failure. It has been thought that the right cavity has a less prominent impact on symptoms, therapeutic approach, and prognosis. Right ventricular dysfunction is a complex issue and its diagnosis has acquired a relevant role, in particular with the improvement of new therapeutic options such as ventricular assist devices.

Multimodal imaging plays a pivotal role in the assessment of the thoracic aorta, both in chronic and acute settings. Moving from improved knowledge on the structure and function of the aortic wall, as well as on its pathophysiology and histopathology, appropriate utilization of each imaging modality results into a better definition of the patient's need and proper treatment strategy. This review is aimed at highlighting the most critical aspects in this field, providing cardiologists with some novel clues for the imaging approach to patients with thoracic aortic disease.

The role of iron toxicity is well known in gastroenterology and hematology: hemochromatosis, thalassemia major and myelodysplastic syndromes represent iron toxicity models with evidence of serious damages to target organs such as the heart, the liver and endocrine tissues. Iron chelation therapy has dramatically changed the survival rate of thalassemia major since the introduction of desferoxamine with quantitative assessment of tissue iron overload by magnetic resonance imaging. Reperfusion hemorrhage is an independent predictor of left ventricular remodeling after acute myocardial infarction.

Magnetic resonance imaging provides excellent spatial resolution and tissue characterization analysis while not exposing patients to ionizing radiation or potentially nephrotoxic iodinate contrast agents. Magnetic resonance imaging has developed into an extensively applied diagnostic tool for all fields of medicine, whilst at the same time an increasing number of patients are being treated with permanent or temporary cardiovascular devices. A thoughtful analysis of cardiovascular devices and their properties related to magnetic field interaction is warranted to improve correct access and safety to magnetic resonance imaging.

Heart failure due to myocardial iron overload remains the leading cause of morbidity and mortality in adult thalassemia major (TM) patients. We evaluated the removal of cardiac iron and the changes of cardiac function by different iron chelation in TM patients by T2* cardiac magnetic resonance (CMR). Sixty-seven TM patients (27 males/40 females; mean age, 35 ± 6 years) on different chelation regimens underwent T2* CMR at baseline (t (0)), after 6-14 months (t (1)) and after 32 ± 7 months (t (2)).

Cardiovascular magnetic resonance (CMR) imaging has become an established imaging modality requiring the definition of standards for data acquisition, reporting and training, recently addressed by a position statement of the Working Group on Cardiovascular Magnetic Resonance of the European Society of Cardiology (ESC). Taking into account the particular difficulties related to CMR implementation in our country, the Working Group on CMR of the Italian Society of Cardiology and the Working Group on Cardiovascular Imaging of the Italian Association of Hospital Cardiologists have prepared this document with the aim to address the logistic, cultural and training problems inhibiting CMR dissemination. The present paper provides recommendations for the inclusion in the School of Cardiology training curriculum of CMR training as suggested by the ESC training curriculum as well as recommendations concerning cardiovascular and radiological training for certification in CMR.

A common clinical practice during single-point Doppler analysis is to measure the centerline maximum velocity and to recover the time-averaged flow rate by exploiting an assumption on the shape of velocity profile (a priori formula), either a parabolic or a flat one. In a previous study, we proposed a new formula valid for the peak instant linking the maximum velocity and the flow rate by including a well-established dimensionless fluid-dynamics parameter (the Womersley number), in order to account for the hemodynamics conditions (Womersley number-based formula). Several in silico tests confirmed the reliability of the new formula.

Acute renal failure (ARF) following percutaneous coronary intervention (PCI) has been shown to be associated with a worse outcome. Whether this event should be considered as a marker of disease severity or an independent contributor to mortality is still unclear.
In a multicenter, prospective cohort study we investigated the predictive variables and the impact of postprocedural ARF on 2-year all-cause mortality in 2860 consecutive patients (50% with stable angina and 50% with non-ST-elevation acute coronary syndromes) undergoing PCI.
