BACKGROUND Pulmonary vascular resistance (PVR) quantification is important in the treatment of children with pulmonary hypertension. The Fick principle, used to quantify pulmonary artery flow, may be a flawed technique. We describe a novel method of PVR quantification by the use of magnetic resonance (MR) flow data and invasive pressure measurements. METHODS AND RESULTS In 24 patients with either suspected pulmonary hypertension or congenital heart disease requiring preoperative assessment… CONTINUE READING
