Understanding the “D Sign” on Echocardiography and Its Implications
The “D Sign” is a characteristic finding on echocardiography that indicates the presence of right ventricular strain. Right ventricular strain refers to an increase in the pressure within the right ventricle, which can cause the septum, a wall that separates the left and right sides of the heart, to shift towards the left side. This shift in the septum causes the left ventricle to take on a D-shaped appearance, which is known as the “D Sign.”
Right ventricular strain can be caused by various conditions, including pulmonary artery hypertension, pulmonary embolism, and right ventricular infarction. It is important to identify and properly manage right ventricular strain, as it can lead to further complications such as heart failure if left untreated. The “D Sign” on echocardiography can be an important clue for healthcare providers in the diagnosis and management of right ventricular strain.
