Abstract:
The aim of this article is to discuss the present and future potential of deformation imaging by echocardiography and scar visualisation by magnetic resonance imaging (MRI) in patients with coronary artery disease (CAD). The two methods are clearly different: one is concerned with function, the other with morphology. Echocardiography, with its versatility of methods and high applicability, will continue to be the workhorse in cardiac imaging of patients with CAD. Important additional information can be extracted from deformation imaging methods, especially due to the high temporal resolution i

Abstract Aims Ventricular tachycardia (VT) in ischaemic cardiomyopathy (ICM) originates from scar, identified as low-voltage areas with invasive high-density electroanatomic mapping (EAM).

We examined if regional and global longitudinal strain (GLS) can localize and quantify low-voltage scar identified with high-density EAM.

Abstract:
Right ventricular (RV) size and function are important predictors of cardiovascular morbidity and mortality in patients with various conditions. However, non-invasive assessment of the RV is a challenging task due to its complex anatomy and location in the chest. Although conventional echocardiography is widely used, its limitations in RV assessment are well recognised. New techniques such as three-dimensional and speckle tracking echocardiography have overcome the limitations of conventional echocardiography allowing a comprehensive, quantitative assessment of RV geometry and function without

We report a case of reversible nonischemic dilated cardiomyopathy in a male in his 60s who presented with an acute heart failure syndrome. Both conventional two-dimensional echocardiography and cardiac magnetic resonance imaging (cMRI) demonstrated severe left ventricular systolic dysfunction; however, both modalities were devoid of significant valvular heart disease as well as the presence of fibrosis, infiltration, inflammation, and scar. After six months of aggressive neurohumoral modulation, there was complete reverse remodeling and normalization of left ventricular function, which highlig

Left bundle branch block (LBBB) is associated with specific septal-to-lateral wall activation patterns which are strongly influenced by the intrinsic left ventricular (LV) contractility and myocardial scar localization. The objective of this study was to propose a computational-model-based interpretation of the different patterns of LV contraction observed in the case of LBBB and preserved contractility or myocardial scarring. Two-dimensional transthoracic echocardiography was used to obtain LV volumes and deformation patterns in three patients with LBBB: (1) a patient with non-ischemic dilate

Abstract:
Restrictive cardiomyopathy (RCM) is the least common among cardiomyopathies. It can be idiopathic, familial, or secondary to systematic disorders. Marked increase in left and/or right ventricular filling pressures causes symptoms and signs of congestive heart failure. Electrocardiographic findings are nonspecific and include atrioventricular conduction and QRS complex abnormalities and supraventricular and ventricular arrhythmias. Echocardiography and cardiac magnetic resonance (CMR) play a major role in diagnosis. Echocardiography reveals normal or hypertrophied ventricles, preserved systolic

Background: Systemic lupus erythematosus (SLE) is an autoimmune disease, which is characterized by a multi-organ involvement and increased mortality, mainly due to cardiovascular complications. Myocardial fibrosis (MF) is common in SLE, affecting up to 30% of these patients. Cardiac magnetic resonance imaging allows an accurate assessment of myocardial tissue in SLE patients, but it is costly, time consuming, and unfit for patients with coexisting chronic kidney disease.

The reduction in mortality from acute myocardial infarction in developed nations has resulted in a larger number of survivors with consequent left ventricular dysfunction. Management of these patients with ischaemic cardiomyopathy remains a challenge, since prognosis remains poor—and worse than that of non-ischaemic heart failure—despite appropriate use of implantable cardioverter-defibrillator and resynchronization devices.

Abstract:
Two principal cardiovascular magnetic resonance (CMR) methods are available for the detection of coronary artery disease (CAD): dobutamine-CMR and perfusion-CMR. With dobutamine-CMR, inducible wall motion abnormalities induced by pharmacological stress are detected as a sign of ischaemia, analogous to dobutamine-stress echocardiography. Dobutamine-CMR provides reliably high image quality regardless of body habitus and is therefore an alternative for patients with insufficient echocardiographic image quality. The principle of perfusion-CMR is most comparable to nuclear myocardial perfusion meth

Sudden cardiac death (SCD) is a major health problem in both the United States and worldwide. There is considerable controversy regarding the optimal time after acute myocardial infarction for risk stratification as well as the ideal time to place an implantable cardioverter defibrillator for primary prevention for SCD. Several parameters have been considered and tested for risk stratification of SCD after acute myocardial infarction.

Abstract:
Ultrasound waves which are sent with a focussed beam into the body and which are reflected and scattered by tissue boundaries are used to compose an image of the heart. The display of a single scan line over time is called M-mode. B-mode images show a 2-dimensional cross section of the heart. A frequency shift of the reflected soundwaves indicates that the reflector is moving which allows to calculate tissue or blood velocities. Velocities are displayed as velocity spectrum or as colour coded overlay over the B-mode image. These so-called Doppler measurements measure true velocities only along
