Complications of pulmonary hypertension: a pictorial review

Pulmonary hypertension (PH) is a rare disease with a significant morbidity and mortality if untreated. The disease has a multifactorial aetiology and is often associated with insidious onset of signs and symptoms. Multimodality imaging is often required for establishing the diagnosis, evaluating the underlying haemodynamic compromise and follow-up after institution of therapy. The range of potential complications associated with PH vary widely. We aimed to summarize the imaging findings of complications that the radiologist should be familiar with.
