Segmentation of compacted and non compacted left ventricular mass with a semi-automatic method
Background The diagnostic of left ventricular (LV) non compaction is still a challenge in clinical practice. There is a lack of reference method able to automatically quantify the total amount of LV trabeculations. Many algorithms have been proposed to determine endocardium and epicardium borders ranging from semi-automated to fully automated methods. However most of the methods were not design...
متن کاملIsolated non-compacted right ventricular myocardium.
Ventricular non-compaction or spongy myocardium is a rare type of cardiomyopathy resulting from arrested myocardial development during embryogenesis. This rare entity is characterized by excessive prominent trabeculations and deep inter-trabecular recesses in the ventricular wall. The clinical manifestations include heart failure, arrhythmias and cardioembolic events. The usual site of involvem...
متن کاملAn unusual case of isolated non-compacted right ventricular myocardium.
Isolated ventricular non-compaction is a rare type of cardiomyopathy resulting from arrested myocardial development during embryogenesis. This rare entity can be easily diagnosed by characteristic appearance of prominent myocardial trabeculations and deep inter-trabecular spaces. The clinical manifestations include heart failure signs, ventricular arrhythmias, and cardio-embolic events. Althoug...
متن کاملRetinoic acid-induced ventricular non-compacted cardiomyopathy in mice.
BACKGROUND Precise tissue concentration of retinoic acid (RA) is indispensable for proper interaction of second heart field cells with cardiac neural crest cells and induction of signalling pathways important for normal myocardial growth. AIM Since RA deficiency during embryogenesis induces noncompaction, we hypothesised that excess RA at the stage of heart tube elongation may cause thinning ...
متن کاملAssessment of left and right ventricular trabeculation and non-compacted myocardium in a large selected healthy reference population
Background The differentiation of left ventricular non-compaction (LVNC) from physiological trabeculation is still challenging as it may be overdiagnosed by current criteria. Therefore, we sought to investigate the effect of age and gender on both the LV and RV trabeculation in a large group of proven healthy subjects to provide adjusted reference values. Furthermore, we examined the correlatio...
