OLT was performed on July 12, 1996. After anesthetic induction,
a pulmonary artery catheter was placed, revealing an MPAP of 48 mm Hg.
Unfortunately, the CI was not measured at that time. Following OLT,
respiratory symptoms improved rapidly, dyspnea decreased from grade III
to grade I of the New York Heart Association classification, and
tricuspid regurgitation disappeared. Due to the poor prognosis of PH
associated with liver disease, we decided to perform a pulmonary
hemodynamic reevaluation in July 1997 (1 year after OLT). We observed a
decrease in the MPAP due to the normalization of the CI (Table 1). The
chronic respiratory alkalosis regressed, and the
P(A-a)O2 decreased. In May 1998, almost 2
years after OLT, the patient was still in good condition and had no
signs of PH. A Doppler echocardiogram showed normal-size right and left
ventricles, as well as the complete disappearance of the tricuspid
regurgitation that was observed initially.
