Pulmonary Arterial Hypertension: Tables and Figures from the 2009 ACC/AHA/ACCP Expert Consensus Document

Postero-anterior and lateral chest X-ray (top) shows decreased peripheral lung vascular markings, hilar pulmonary artery prominence, and right ventricular enlargement of a patient with idiopathic PAH.

ECG indicates electrocardiogram; and PAH, pulmonary arterial hypertension.
