Pulmonary Hypertension

Abstract

Pulmonary hypertension (PH) is defined as a pulmonary capillary wedge pressure >25 mm Hg. Patients tend to present with nonspecific symptoms centered on worsening dyspnea. The causes of PH are classified according to the Dana Point classification which groups causes of PH based on shared pathophysiology and treatments. In the initial work up of patients with PH, the goal of imaging is determine if there are findings of PH and to look for clues to the underlying cause so that patients are treated appropriately. MRI can be useful in the follow up of patients with PH, as it can evaluate for changes in the right ventricle.
