asymmetric septal hypertrophy


Also called hypertrophic cardiomyopathy, asymmetric septal hypertrophy is a condition that occurs when heart muscles cells enlarge, causing the walls of the lower heart chambers (typically the left ventricle) to become thick and stiff. This makes it difficult for the heart to relax and for a sufficient amount of blood to fill the heart chambers. While the heart squeezes normally, the limited filling prevents the heart from pumping enough blood, especially during physical activity. Children with asymmetric septal hypertrophy are not allowed to play competitive sports because of the possibility of a sudden collapse or increased heart failure.
