Full Answer
Left ventricular outflow tract obstructions involve stenotic lesions starting in the anatomic left ventricular outflow tract and stretching to the descending portion of the aortic arch. Obstruction can be valvar, subvalvar, or supravalvar. Obstructions to forward flow can present alone or in concert.
The electrocardiogram is usually normal. However, with isolated forms of LVOT obstruction, left ventricular hypertrophy and left axis deviation may be present. Transthoracic echocardiography will often demonstrate a focal or diffuse narrowing of the LVOT.
HCM is characterized by disorganized myocytes which lead to hypertrophy of the left ventricle, usually the septum. However, hypertrophy can be extensive involving the LV free wall as well. It is an autosomal dominant disease with equal prevalence in males and females.
In general, there is an obstruction to forward flow which increases afterload, and if untreated, can result in hypertrophy, dilatation, and eventual failure of the left ventricle. In the United States, most cases of LVOT obstruction are congenital in individuals younger than 50 years of age.[1]

When the aortic or mitral valves are leaking, the left ventricle adapts to the increased volume load by getting larger. This results in cardiomegaly. If the aortic valve is narrow, this results in an obstruction to the left ventricle which develops hypertrophy and cardiomegaly.
Left ventricular hypertrophy, or LVH, is a term for a heart's left pumping chamber that has thickened and may not be pumping efficiently. Sometimes problems such as aortic stenosis or high blood pressure overwork the heart muscle.
Endocardial fibroelastosis (EFE) is a rare heart disorder that affects infants and children. It is characterized by a thickening within the muscular lining of the heart chambers due to an increase in the amount of supporting connective tissue (inelastic collagen) and elastic fibers.
It was previously called arrhythmogenic right ventricular dysplasia (ARVD). ARVC typically begins in a small part of the right ventricle. Over time, the disease slowly affects more of the right ventricle. Sometimes the left ventricle is affected, too. This can lead to abnormal heart rhythms, and sometimes sudden death.
High blood pressure (hypertension). This is the most common cause of left ventricular hypertrophy. More than one-third of people show evidence of left ventricular hypertrophy at the time of their diagnosis with hypertension.
Dilated cardiomyopathy is the most common type of cardiomegaly. In this condition, the walls of the left and/or right ventricles of the heart become thin and stretched. The result is an enlarged heart. In the other types of cardiomegaly, the heart's large muscular left ventricle becomes abnormally thick.
Hypertrophic cardiomyopathy (HCM) is a disease that causes your heart muscle to enlarge (hypertrophy). Most people who have it can have a normal life, but it can be serious for some people.
The most common cause of left ventricular hypertrophy is high blood pressure (hypertension). High blood pressure makes your heart work harder than normal. The extra work it takes to pump blood can cause the muscle in the left ventricle walls to get larger and thicker.
Structural remodeling of the heart, referred to as left ventricular hypertrophy (LVH), is a critical consequence of systemic hypertension and the anatomical precursor of a spectrum of cardiovascular abnormalities, which are collectively referred to as hypertensive heart disease.
Echocardiogram can reveal thickened muscle tissue in the left ventricle, blood flow through the heart with each beat, and heart abnormalities related to left ventricular hypertrophy, such as aortic valve stenosis. MRI. Images of your heart can be used to diagnose left ventricular hypertrophy.
