Pulmonary resistance: How best to measure?

Research output: Chapter in Book/Report/Conference proceedingChapter


Assessing the pulmonary vascular resistance (PVR) is important in subjects with intra-cardiac shunts who present later in life or those with functionally univentricular physiology where there is suspicion of raised pulmonary arterial pressures. Methods to measure PVR include catheter or combined catheter and magnetic resonance imaging (XMR). Whilst catheter alone is more easily performed and available, XMR techniques offer improved accuracy particularly in the presence of large shunts or when using vasodilator agents. We describe two cases where PVR was calculated and was crucial in planning further management.
