Magnetic resonance imaging of atrial fibrosis: redefining atrial fibrillation to a syndrome.
Atrial fibrillation (AF) is the most common sustained arrhythmia and its treatment continues to be a challenge. Recently, delayed enhancement (DE)-MRI was introduced in the diagnosis and treatment of AF by the assessment of atrial fibrosis, which is considered the hallmark of the arrhythmogenic substrate in AF. Atrial fibrosis was reported to be an independent predictor of arrhythmia recurrence...
متن کاملLeft atrial aging: a cardiac magnetic resonance feature-tracking study.
Importance of left atrial (LA) phasic function evaluation is increasingly recognized for its incremental value in terms of prognosis and risk stratification. LA phasic deformation in the pathway of normal aging has been characterized using echocardiographic speckle tracking. However, no data are available regarding age-related variations using feature-racking (FT) techniques from standard cine ...
متن کاملCardiovascular magnetic resonance and PET-CT of left atrial paraganglioma
Cardiac paragangliomas are among the rarest primary cardiac tumors. We present a case of left atrial paraganglioma in a patient who presented with symptoms and signs of catecholamine excess in which cardiovascular magnetic resonance in multiple orientations and PET-CT played an important role in the diagnosis and tissue characterization.
متن کاملHow to measure left atrial volume.
Figure 1. M-mode measurement of LA size from a parasternal window. According to ASE guidelines, the measurement (leading-edge to leading-edge method) is performed at end-systole, measured at the maximum dimension from the leading edge of the posterior wall of the aorta, to the dominant line of the posterior wall of the LA (arrows). aortic root. The anteroposterior LAD is used to measure LA size...
متن کاملMagnetic resonance image-guided transcatheter closure of atrial septal defects.
BACKGROUND Recent developments in cardiac MRI have extended the potential spectrum of diagnostic and interventional applications. The purpose of this study was to test the ability of MRI to perform transcatheter closures of secundum type atrial septal defects (ASD) and to assess ASD size and changes in right cardiac chamber volumes in the same investigation. METHODS AND RESULTS In 7 domestic ...
