TL;DR: Mortality was most closely associated with right ventricular hemodynamic function and can be characterized by means of an equation using three variables: mean pulmonary artery pressure, mean right atrial pressure, and cardiac index.

TL;DR: Recent surveys of Guidelines and Expert Consensus Documents published in peer-reviewed journals between 1985 and 1998 have shown that methodological standards were not complied with in the vast majority of cases.

TL;DR: A histopathological classification is proposed that includes both the predominant segment of the pulmonary vasculature affected and the possible coexistence of pathological changes in other vascular segments in PAH.

TL;DR: Results indicate a smooth transition of helix angle from epi- to endocardial surface in the normal left ventricular free wall with nearly 55 per cent of the wall occupied by circumferentially oriented fibers near the cardiac equator.

TL;DR: Qualitative histologic examination of lung tissue did not provide a basis for predicting how individual patients would respond to vasodilator agents, but quantitative morphologic analysis of the initial open lung biopsy specimens did prove helpful in predicting acute responsiveness to vasodermal agents and the subsequent clinical course of these patients with unexplained (primary) pulmonary hypertension.
