Dilated cardiomyopathy
No full textDilated cardiomyopathy (DCM) is defined by the presence of LV dilatation and systolic dysfunction in the absence of significant CAD or an abnormal loading condition sufficient to cause global systolic impairment. The causes of DCM can be classified as genetic and nongenetic. Echocardiography, Cardiovascular Magnetic Resonance (CMR), nuclear imaging (SPECT and PET),
and cardiac CT are valuable tools for the diagnosis and stratification of DCM patients. Specifically, the chapter is about the role of cardiovascular imaging in the diagnostic algorhythm of dilated cardiomyopathy including indication of scan protocol and report
Heart failure and iron deficiency
No full textHeart failure (HF) is a major public health problem because it is one of the most common causes of morbidity and mortality in Western countries, with a prevalence of 1–2% in the adult population, rising to ≥10% in those age >70 years. In addition to the “classic” co-morbidities, such as COPD, arterial hypertension, diabetes, renal failure, etc., there are other conditions frequently found in patients with heart failure that many times areunderestimated. One example are anemia and iron deficiency (ID). ID, regardless of anemia impair exercise tolerance, symptoms and quality of life, with a strong negative prognostic impact on hospitalization and mortality rate. Despite strong evidence of high prevalence of ID in these patients and current guidelines recommendations, the diagnosis of ID and its monitoring over time still have low priority for physicians in clinical practice. Consequently ID is under-treated; furthermore current therapies, in particular i.v. iron as ferric carboxymaltose, though effective, turn out to be poorly managed by clinicians. ID should be considered more in real world HF healthcare settings to improve patients’ quality of life and outcome

No full textCardiovascular magnetic resonance of a hiatus hernia causing positional cardiac compression
No full textA69-year-old lady with intermittent breathlessness and chest pain underwent cardiovascular magnetic resonance (CMR) in the supine position. A large hiatus herniawas seen compressing the left ventricle, atrium, and mitral annulus. The CMR, including adenosine stress perfusion, was otherwise normal. The patient was immediately repositioned into the prone position and rescanned. In this position, the cardiac compression from the hiatus hernia was reduced, thus demonstrating its positional nature. Positional cardiac compression may in fact be an under-diagnosed phenomenon. Echocardiography in the left lateral decubitus position may not detect compression that occurs only when supine, unless an index of suspicion calls to reposition the patient, which is feasible with echocardiography. CMR may be more likely to detect this rare phenomenon given its supine nature
The role of cardiovascular magnetic resonance in the screening before the return-to-play of elite athletes after COVID-19: utility o futility?
No full text: Recent reports based on cardiovascular magnetic resonance (CMR) showed a wide range of prevalence of inflammatory heart diseases in COVID-19 convalescent athletes ranging from 0.4 up to 15%. These observations had an important impact in the field of sport cardiology opening an intense debate around the best possible screening strategy before the return-to-play. The diagnostic yield of CMR for detecting acute inflammatory disease is undebatable. However, the opportunity to use it in the screening protocol after COVID-19 has been questioned. Current evidence does not seem to support the routine use of CMR and the prescription of CMR should be based upon clinical indication
Narrating the museum to promote empathy and critical thinking in medical science students and doctors through online activities: a pilot research experience
Full text linkL'esperienza di ricerca "Narrare il museo per promuovere l’empatia e il pensiero critico in studenti di medicina e dottori", realizzata nell'ambito del progetto "Inclusive Memory", co-finanziato dall’Università Roma Tre, mira a promuovere l'empatia e la capacità di pensiero critico nei medici, anche in formazione, attraverso attività di educazione al patrimonio. Le caratteristiche innovative dell'esperienza di ricerca risiedono nell'utilizzo di attività online, che combinano diverse metodologie di apprendimento: Visual Thinking Strategies, Reflective Questioning, Storytelling e Object-based learning. Il contributo presenta i risultati dell'attività pilota svolta dal gruppo di ricerca del Centro di Didattica Museale, con sede presso il Dipartimento di Scienze della Formazione dell’Università Roma Tre, in collaborazione con Sapienza Università di Roma. Vengono inoltre descritte le attività didattiche, gli strumenti di apprendimento e di valutazione utilizzati durante tale esperienza, che ha coinvolto 35 partecipanti. I risultati della sperimentazione descritta evidenziano un miglioramento statisticamente significativo per quanto riguarda l’indicatore di pensiero critico “uso della lingua” e un miglioramento della dimensione empatica della sensibilità al contesto; i partecipanti dichiarano che i loro livelli di comunicazione e pensiero critico migliorano alla fine delle attività e che gli esercizi progettati stimolano la riflessione, l'osservazione e l'interpretazione.The research experience "Narrating the museum to promote empathy and critical thinking in medical science students and doctors through online activities", carried out within the "Inclusive Memory" project, co-funded by University Roma Tre, aims at promoting empathy and critical thinking skills in medical science students and doctors through heritage education activities. The innovative features of the research experience lie in the use of online activities, combining different learning methodologies: Visual Thinking Strategies, Reflective Questioning, Storytelling and Object-Based Learning. The paper presents the results of the pilot activity carried out by the Centre for Museum Studies research group, based at the Department of Education – Roma Tre, in collaboration with the Sapienza University of Rome. It also describes the teaching activities, learning and evaluation tools used during the pilot experience, which involved 35 participants. The trial results highlight a statistically significant improvement in the Critical Thinking use of language indicators and an improvement of Sensitivity to the context empathy dimension; participants state that their levels of communication and critical thinking skills improved at the end of the activities and that the exercises foreseen stimulated reflection, observation and interpretation
