Asymmetrical septal hypertrophy is a medical condition that refers to the enlargement or thickening of the muscular wall, known as the ventricular septum, which divides the two lower chambers (the left and right ventricles) of the heart. The hypertrophy, a term indicating excessive growth, occurs in an asymmetrical or uneven manner, leading to an abnormal thickness of the septum.
This condition is commonly associated with hypertrophic cardiomyopathy (HCM), a genetic heart disease that affects the structure and function of the heart muscle. Hypertrophic cardiomyopathy is characterized by the thickening of the ventricular walls, and in particular, the septal hypertrophy seen in asymmetrical septal hypertrophy is a distinguishing feature of this disease.
The uneven thickening of the septum in asymmetrical septal hypertrophy can result in the narrowing of the left ventricular outflow tract, the passage connecting the left ventricle with the aorta. This narrowing can impede the flow of blood out of the heart, causing symptoms such as shortness of breath, chest pain, fatigue, and palpitations.
Treatment for asymmetrical septal hypertrophy typically focuses on managing symptoms and reducing the risk of complications. It may involve medications to improve heart function, relieve symptoms, and prevent abnormal heart rhythms. In some cases, surgical interventions like septal myectomy or septal alcohol ablation may be necessary to remove excess tissue or open up the narrowed passage and improve blood flow. Regular monitoring and follow-up care are crucial to effectively manage this condition and maintain overall cardiac health.
