CMR for Identifying the Substrate of Ventricular Arrhythmia in Patients With Normal Echocardiography

Cardiac Magnetic Resonance Imaging for Nonischemic Cardiac Disease in Out-of-Hospital Cardiac Arrest Survivors Treated with Targeted Temperature Management: A Multicenter Retrospective Analysis

“…An explanation for our result is the difference in study population. Previous studies included heterogeneous group of patients from non-sustained ventricular tachycardia to a history of resuscitated cardiac arrest [11,24]. However, patients treated with TTM have different characteristics to these study populations.…”

The cardiac conundrum: a systematic review and bibliometric analysis of authorship in cardiac magnetic resonance imaging studies

“…The last 20 years has seen an explosion of research in cardiac-MRI, and the potential of this technique to accurately depict in one single section, myocardial morphology, function, and perfusion, has led it to become a powerful tool in the diagnostic work up of patients with CV diseases [22][23][24][25]. In particular, this technique is mainly used in clinical practice for the assessment of congenital heart disease, ischemic and non-ischemic cardiomyopathies, valvular and pericardial diseases, and myocardial tumor [3,16,[25][26][27][28][29]. Consequently, there has been a steady increase and a Fig.…”

“…This is also reflected in the scientific literature, with more and more papers being published employing CV imaging [2]. Interest in and use of cardiac MRI have also increased as it allows for morphological and functional imaging of the heart, with a wide range of indications [3][4][5][6][7][8][9]. Yet, there is some overlap in both clinical practice and research in regard to the role of different medical specialties, especially radiology and cardiology, leading to some debate [10].…”

Electroanatomic mapping‐guided endomyocardial biopsy in patients with apparently idiopathic ventricular arrhythmias

“…1,2 The introduction of new imaging techniques and the spreading of next-generation genetic testing have significantly improved our knowledge of the pathogenesis of "apparently idiopathic VA," demonstrating that identification of the substrate may significantly influence both prognosis and treatment. 3 Nevertheless, in the absence of specific recommendations, the type and the number of noninvasive and invasive studies necessary to rule out a possible underlying cause of VA or sudden cardiac death (SCD) remain extremely variable. Endomyocardial biopsy (EMB) can provide a significant contribution to the identification of myocardial disorders causing VA but has never been definitively included in the routine diagnostic work-up of these patients, due to the potential sampling error mostly in disorders with a focal or patchy distribution.…”

“…The management of ventricular arrhythmias (VA) in the presence of an apparently normal heart represents a major clinical challenge and a main field of clinical research 1,2 . The introduction of new imaging techniques and the spreading of next‐generation genetic testing have significantly improved our knowledge of the pathogenesis of “apparently idiopathic VA,” demonstrating that identification of the substrate may significantly influence both prognosis and treatment 3 …”
