1. a) Pressure tracings from the aorta (AO) and pulmonary artery (PA), demonstrating systemic levels of pulmonary arterial pressures.
a) Pressure tracings from the aorta (AO) and pulmonary artery (PA), demonstrating systemic levels of pulmonary arterial pressures. Mean pulmonary arterial pressure is 54 mmHg. b) Cardiac magnetic resonance showing the large patent ductus arteriosus (PDA), with bidirectional shunting between the PA to the descending AO. c) Computed tomography of the thorax demonstrating an area of intrapulmonary haemorrhage in the left upper lung (white arrow). The PDA is also seen between the AO and PA (black arrow).
