Interventricular Septum Thickness Unit Converter

Interventricular septum thickness (IVSd) is a measurement of the muscular wall that separates the left and right ventricles of the heart. It is typically measured at end-diastole (when the heart is relaxed and filling with blood) using echocardiography.

Normal values are generally 0.6–1.0 cm in men and 0.6–0.9 cm in women. The septum naturally thickens with age, increasing from a median of about 8.3 mm in adults aged 20–29 to approximately 11.2 mm in those aged 60–70.

An abnormally thick septum may indicate left ventricular hypertrophy or hypertrophic cardiomyopathy, while focal thinning can be associated with conditions such as cardiac sarcoidosis or prior myocardial infarction.

The interventricular septum is a muscular wall composed primarily of cardiac muscle (myocardium) that forms during fetal heart development. Its thickness reflects the amount and condition of heart muscle tissue at that location, which is influenced by hemodynamic load, genetics, and underlying cardiac conditions.
