PULMONARY VASCULAR-RESISTANCE VARIATION OVER LIME IN CANDIDATES FOR HEART-TRANSPLANTATION

Increased pulmonary vascular resistance (PVR) is an incremental factor for early death after heart transplantation.1 Because PVR modifications are largely unpredictable in amount and rate, and the time spent by patients on the waiting list is often long, periodic reassessment of pulmonary hemodynamics is advisable.2 To quantify PVR variation over time and identify the factors that determine such variation, we retrospectively analyzed the hemodynamic parameters of pulmonary circulation measured on 2 different occasions in a group of patients who were candidates for heart transplantation. © 1994.
