In “Ask the Expert” on page 92 of Volume 13, Number 2, the sentence beginning on the 15th line of the right-hand column should read: “In AMBITION, first-line treatment with a combination endothelin receptor antagonist (ERA, ambrisentan) and concomitant phosphodiesterase type 5 inhibitor (PDE-5i, tadalafil) was compared with either medication alone as first-line therapy for World Health Organization (WHO)/New York Heart Associaton (NYHA) functional class II–III symptoms.”
