The role of agitated saline contrast echocardiography in the evaluation of pulmonary hypertension.

The diagnostic approach to pulmonary hypertension using cardiac imaging, particularly echocardiography, provides a practical, accessible, and highly valuable tool. It helps establish the initial diagnostic probability, offers prognostic information, and supports aetiological assessment. The agitated saline contrast test, also referred to as bubble contrast echocardiography, can aid not only in confirming the diagnosis but also in characterising the condition and identifying various underlying causes of pulmonary hypertension.
