Advanced cardiac magnetic resonance imaging in takotsubo cardiomyopathy

Takotsubo cardiomyopathy (TC) is a reversible condition in which there is transient left ventricular (LV) dysfunction characterised most commonly by basal hyperkinesis and mid-apical LV ballooning and hypokinesia. It is said to be triggered by stress and mimics, such as acute coronary syndrome (ACS) clinically. Diagnosis is usually suspected on echocardiography due to the characteristic contraction pattern in a patient with symptoms and signs of ACS but normal coronary arteries on catheter angiography. Cardiac magnetic resonance (CMR), with its latest advancements, is the diagnostic modality of choice for diagnosis, prognosis and follow-up of patients. The advances in CMR (including T1, T2, ECV mapping and threshold-based late gadolinium enhancement (LGE) measurements have revolutionised the role of CMR in tissue characterisation and prognostication in patients with TC. In this review, we highlight the current role of CMR in management of TC and enumerate the CMR findings in TC as well the current advances in the field of CMR, which could help in prognosticating these patients.

Utility of Cardiac MRI in Atrial Fibrillation Management.

Advances in cardiac magnetic resonance (CMR) techniques and image acquisition have made it an excellent tool in the assessment of atrial myopathy. Remolding of the left atrium is the mainstay of atrial fibrillation (AF) development and its progression. CMR can detect phasic atrial volumes, atrial function, and atrial fibrosis using cine, and contrast-enhanced or non-contrast-enhanced images. These abilities make CMR a versatile and extraordinary tool in management of patients with AF including for risk stratification, ablation prognostication and planning, and assessment of stroke risk. We review the latest advancements in utility of CMR in management of patients with AF.

Cardiac MRI: a Promising Diagnostic Tool to Detect Cancer Therapeutics–Related Cardiac Dysfunction

Recent advances in oncological research have led to a major improvement of mortality amongst cancer patients. However, survivors are at an increased risk to develop cancer therapeutics–related cardiac dysfunction (CTRCD). The management of CTRCD may pose a challenge due to its heterogeneous clinical presentation. This warrants the need for a multi-modality diagnostic tool to objectively acquire prognostic information for timely commencement of cardio-protective treatment. Cardiac magnetic resonance (CMR) imaging offers considerable potential due to its non-invasive, reproducible protocol. Moreover, biomarkers such as T1 and T2 mapping allow discrimination between oedematous and fibrotic myocardium, providing an invaluable diagnostic algorithm to track the temporal evolution of CTRCD. In this review, we appraise current evidence for the role of CMR in the management of CTRCD, placing emphasis on ventricular function, strain, late gadolinium enhancement and parametric mapping. We recommend a central role for CMR in the interdisciplinary management of CTRCD.

Current Concepts on Diagnosis and Prognosis of Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia.

Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is an uncommon cardiac disease characterized by progressive right ventricular dysfunction due to fibrofatty replacement of myocytes and risk of sudden cardiac death from malignant arrhythmias. ARVC/D is a disease of the cardiac desmosome, with genetic mutations in genes encoding proteins critical to this structure found in the majority of patients. The diagnosis of ARVC/D is based on fulfilling a combination of clinical, imaging, pathologic, and/or genetic criteria set forth by the 2010 modified Task Force Criteria. Cardiac magnetic resonance (CMR) is included in these criteria and plays an important role in the management of ARVC/D, demonstrating pathologic structural changes in the right and left ventricles that provide both diagnostic and prognostic information. The purpose of this article is to provide a background on the pathophysiology and genetics of ARVC/D and focus on the role of CMR in management of ARVC/D including diagnosis, prognosis, and treatment decisions. Common CMR pitfalls that can lead to misdiagnosis will also be reviewed.

Cardiac magnetic resonance in management of myocarditis and cardiomyopathy

METODE I REzULTATI: Iako histologija ostaje zlatni standard za utvrđivanje dijagnoze kod bolesnika s niskim rizikom u klinickoj je praksi cesto dovoljan kompatibilni klinicki tijek i oslikavanje magnetnom rezonancijom (MR) srca bez endomiokardijalne biopsije. Oslikavanje pomocu MR srca omogucuje otkrivanje razlicitih znacajki miokarditisa, u prvom redu upale i edema, nekroze misicnih stanica i ožiljka, promjene u volumenu i geometriji klijetki, poremecajima kontraktilnosti i pratecih manifestacija zahvacenosti perikarda. U slucaju kardiomiopatija neobicno je važno pravovremeno postavljanje dijagnoze jer je navedeno direktno povezano s lijecenjem i preživljenjem bolesnika.
