Measuring pulmonary arterial compliance: mission impossible? Insights from a novel in vivo continuous-flow based experimental model.

Arterial compliance (C) is related to the elasticity, size, and geometrical distribution of arteries. Compliance is a determinant of the load that impedes ventricular ejection. Measuring compliance is difficult, particularly in the pulmonary circulation in which resistive and compliant vessels overlap.

How to cope with a temporarily aborted transplant program: solutions for a prolonged waiting period.

Background: Due to budgetary restrictions our university heart transplant program came to a standstill to be gradually restarted early 2011. Consequently waiting-times for transplantation increased dramatically beyond the usual 10-15 months. We reviewed the clinical results of this peculiar transplant program over the past 4 years.
