What is the typical presentation of pulmonary hypertension on echocardiography?

The typical presentation of pulmonary hypertension on echocardiography is characterized by right ventricular pressure overload and right ventricular dilation. In the context of pulmonary hypertension, the increased pressure in the pulmonary arteries leads to significant changes in the right ventricle. When the right ventricle faces elevated pressures, it can become hypertrophied and dilated as it works harder to pump blood into the high-resistance pulmonary circulation. This dilation can be observed on echocardiographic images, often accompanied by a paradoxical interventricular septal motion due to the increased right ventricular pressure.

Moreover, echocardiography can show relevant findings such as the right ventricular wall motion abnormalities or dilated right atrium due to the elevated pressures and volume overload. This emphasizes the right heart's struggles to cope with the increased burden of pumping against higher pressures, which is the hallmark of pulmonary hypertension.

In contrast, the other options do not align with the typical echocardiographic findings associated with pulmonary hypertension. Increased left ventricular size is more commonly seen in conditions leading to left-sided heart failure or volume overload. Decreased aortic pressure is not a direct indicator of pulmonary hypertension but can occur due to various other hemodynamic changes. Lastly, thickening of the ventricular walls generally
