	Asymmetric septal hypertrophy - Health Encyclopedia
		hypertrophic cardiomyopathy, idiopathic hypertrophic subaortic stenosis, IHSS (idiopathic hypertrophic subaortic stenosis), obstructive asymmetric septal hypertrophy
		Asymmetric septal hypertrophy is often suggested by very deep septal Q waves in leads I, aVL, V5, and V6; a QS complex sometimes occurs in V1 and V2, simulating previous septal infarction.
		Asymmetric septal hypertrophy — Asymmetric septal hypertrophy is an abnormal thickening of the heart muscle inside the lower left chamber (left ventricle) of the heart.

	Hypertrophic Cardiomyopathy: Heart Failure and Cardiomyopathies: Merck Manual Professional
		During systole, the septum thickens, and sometimes the anterior leaflet of the mitral valve, already abnormally oriented because of the abnormally shaped ventricle, is sucked toward the septum by a Venturi effect of high velocity blood flow, further obstructing the outflow tract and decreasing cardiac output.
		Septal hypertrophy produces a systolic ejection-type murmur that does not radiate to the neck and may be heard at the left sternal edge in the 3rd or 4th intercostal space.
		Genetic counseling is appropriate for patients with asymmetric septal hypertrophy, which appears to accelerate during puberty.

		The most common form of hypertrophic cardiomyopathy is diffuse hypertrophy of the ventricular septum and anterolateral free wall (70% to 75% of cases) (figure 2: not shown), followed by basal septal hypertrophy (10% to 15%), concentric hypertrophy (<5%), hypertrophy of the lateral wall (1% to 2%), and apical hypertrophy (5).

		The disease includes asymmetric septal hypertrophy, and idiopathic subaortic stenosis (IHSS), but the term HCM is preferred because the majority (75%) of patients do not present with outflow obstruction (Braunwald, 1997), and 30% do not exhibit asymmetric hypertrophy.
		On echocardiograms, asymmetrical septal hypertrophy is defined as a ratio of septal thickness to posterior wall thickness of at least 1.3-1.5.
		The left septal surface is flat or it bulges into the LV cavity at its middle or lower portion, in contrast to the normal curve toward the right ventricle.

		This hypertrophy can occur in any region of the left ventricle but frequently involves the interventricular septum, which results in an obstruction of flow through the left ventricular (LV) outflow tract.
		The pressure gradient appears to be related to further narrowing of an already small outflow tract (by the marked asymmetric septal hypertrophy and possibly an abnormal location of the mitral valve) by the systolic anterior motion of the mitral valve against the hypertrophied septum.
		The molecular basis for HCM is defects in several of the genes encoding for the sarcomeric proteins, such as myosin heavy chain, actin, tropomyosin, and titin.

		Asymmetric septal hypertrophy, found at increased incidence in infants of insulin-dependent diabetic mothers, often hinders diastolic function, as evidenced by decreased cardiac output and increased morbidity, including persistent pulmonary hypertension of the newborn, and perhaps idiopathic respiratory distress syndrome (1,2,8).

		It can be seen from figure 5 that the hypertrophy is usually greatest in the upper septum, in the area where blood flows out of the heart into the aorta or "outflow tract".
		In some cases of asymmetric septal hypertrophy obstruction to the outflow of blood from the heart may occur as shown here.

		Symmetric or asymmetric septal hypertrophy may be present and the aortic valve shows abnormal systolic closure and fluttering.
		The asymmetric septal hypertrophy is variable in degree and position and may be secondary to other lesions, such as coarctation, systemic hypertension, right ventricular hypertrophy, or valvular aortic stenosis.

		The hallmark of the disorder is myocardial hypertrophy that is inappropriate, often asymmetric, and occurs in the absence of an obvious inciting hypertrophy stimulus.
		Although any region of the left ventricle (LV) can be involved, hypertrophy frequently involves the interventricular septum, which results in an obstruction in the LV outflow tract.
		The pressure gradient appears to be related to further narrowing of the outflow tract, already made small by the marked asymmetric septal hypertrophy and the possibly abnormally located mitral valve, by systolic anterior motion of the mitral valve against the hypertrophied septum.
