1 Relationship between pulmonary arterial resistance and compliance among patients with pulmonary arterial hypertension and congenital heart disease  Jun Muneuchi, MD, Yusaku Nagatomo, MD, Mamie Watanabe, MD, Kunihiko Joo, MD, Tatsushi Onzuka, MD, Yoshie Ochiai, MD, Kunitaka Joo, MD  The Journal of Thoracic and Cardiovascular Surgery  Volume 152, Issue 2, Pages (August 2016) DOI: /j.jtcvs Copyright © 2016 The American Association for Thoracic Surgery Terms and Conditions

2 Figure 1 The plots of Rp against Qp/Qs show an inverse relationship (A), whereas the plots of Cp against Qp/Qs show a linear proportional relationship (B). Rp, Pulmonary arterial resistance; Qp, pulmonary blood flow; Qs, systemic blood flow; Cp, pulmonary arterial compliance.

3 Figure 2 The relationship between pulmonary arterial resistance (Rp) and compliance (Cp) before (closed circles) and after (open circles) surgery (A); individual changes are shown as connecting lines (B). The plots of the logarithms of Rp (ln Rp) and Cp (ln Cp) show a linear relationship (C).
