A transthoracic echocardiogram (TTE) helps physicians evaluate patients with suspected pulmonary hypertension (PH)1:
Enables indirect assessment of pulmonary arterial pressure
Permits evaluation of intracardiac shunt or left-heart disease as causes of PH
The following findings suggest PH1:
Right ventricular dilatation or overload
Right atrial enlargement, hypertrophy, and hypokinesis
An echocardiogram may be performed 6 weeks after acute pulmonary embolism (PE) to screen for persistent PH that may predict the development of chronic thromboembolic pulmonary hypertension (CTEPH).2
