What is LVHT?
Left ventricular non-compaction, also known as left ventricular hypertrabeculation (LVHT), is a morphological abnormality of the left ventricular myocardium, characterised by a meshwork of myocardial strings, interlacing, and orderless in arrangement.
What is prominent Trabeculation?
Prominent myocardial trabeculations and deep intertrabecular recesses are most likely a result of an early arrest of the compaction process during embryogenesis and are thus morphological features of left ventricular noncompaction (LVNC). LVNC is thought to be rare.
What does Noncompaction mean?
Left ventricular noncompaction is a heart (cardiac) muscle disorder that occurs when the lower left chamber of the heart (left ventricle), which helps the heart pump blood, does not develop correctly. Instead of the muscle being smooth and firm, the cardiac muscle in the left ventricle is thick and appears spongy.
How serious is LVNC?
The most serious complication of LVNC is sudden cardiac arrest. Sudden cardiac arrest is a sudden loss of heart function caused by a dangerously fast heart rhythm called ventricular tachycardia.
What causes Trabeculations?
Trabeculation of the bladder occurs from repeated obstructions in the urethra. When an obstruction occurs, the muscles walls of the bladder have to work too hard to move urine past the blockage. This leads to a thickening of the muscle walls and a loss of elasticity.
What is Hypertrabeculation Noncompaction?
Abstract. Ventricular hypertrabeculation (noncompaction) is a poorly characterized condition associated with heart failure. The condition is widely assumed to be the retention of the trabeculated ventricular design of the embryo and ectothermic (cold-blooded) vertebrates.
Is LVNC a congenital heart defect?
Conclusion: In adults, various forms of congenital heart disease are associated with LVNC, particularly stenotic lesions of the left ventricular outflow tract, Ebstein anomaly, and tetralogy of Fallot.
Where are the trabeculations located in the left ventricle?
<< Learn more about the Heart Institute. In left ventricular non-compaction cardiomyopathy (LVNC) the lower left chamber of the heart, called the left ventricle, contains bundles or pieces of muscle that extend into the chamber. These pieces of muscles are called trabeculations.
What does trabeculae mean in terms of anatomy?
1. The occurrence of trabeculae in the walls of an organ or part. 2. The process of forming trabeculae, as in spongy bone. The formation of ridges on a surface. Want to thank TFD for its existence?
How are Lv trabeculations related to the cardiac cycle?
Although the criteria rely on the presence of increased LV trabeculations and the presence of a double myocardial layer, an outer compacted area and an inner noncompacted layer, they differ from each other with respect to the precise area and timing in the cardiac cycle for the measurement of the compacted and noncompacted layers.
What are the symptoms of left ventricular trabeculations in athletes?
AF = atrial fibrillation; CMR = cardiac magnetic resonance imaging; LBBB = left bundle branch block; LV = left ventricular; VT = ventricular tachycardia. Patients with LVNC frequently (75%) express symptoms of LV dysfunction whereas athletes are asymptomatic.
