Assessment of ventricular elements of mitral valve by left ventriculography.
In the left ventriculogram in the right anterior oblique projection the plane of the mitral valve is seen in profile and the papillary muscle shadows are outlined. The distance from the middle of the papillary muscles to the plane of the mitral valve during systole was used to assess the average length of the chordae tendineae, and the area of the papillary muscle shadows was measured as an ind...
متن کاملThe Current Status of Performing Left Ventriculography in Taiwan.
BACKGROUND Left ventriculography (LVG) is a gold standard examination of left ventricular function, although it also involves a small but significant risk of complications. However, it was recently reported to be overused in the USA in comparison to an alternative imaging modality. In this study, our aim was to analyze the real-world use of LVG in Taiwan. METHODS This cohort study analyzed th...
متن کاملNoncompaction of the left ventricular myocardium diagnosed during ventriculography.
Corresponding Author: Mehmet Ali Elbey, MD; e-mail: [email protected] 565 Dear Editor, The noncompacted myocardium (NCM) is characterised prominent trabeculations and deep intertrabecular recesses due to interruption of the myocardial fiber compacting during embryogenesis. Major clinical features of NCM include heart failure, arrhytmias and thromboembolic events. A 40-year-old man with shor...
متن کاملLeft Ventricle Tracking in Isotopic Ventriculography Using Statistical Deformable Models
The left ventricle tracking in planar scintigraphic images is an important step to study the coronary state. However, it is not as simple as we thought, because of the bad quality of these images. The study of the related work showed that classic methods based on low level image characteristics failed to localize the ventricle. In this paper, we suggest using a method based on a priori knowledg...
متن کاملCardiac Ventriculography
Cardiac ventriculography is used to define the anatomy and function of the ventricles and related structures in patients with congenital, valvular, coronary, and myopathic heart disease (1–5). Specifically, left ventriculography may provide valuable information about global and segmental left ventricular function, mitral valvular incompetence, and the presence, location, and severity of a numbe...
