Recognition of Ultrasound Artifact Mimicking Pulmonary Artery Dissection in Patients with Heart Disease

Table 2

Differences between pulmonary imaging artifact and pulmonary artery dissection.

Baseline data	Pulmonary artifact	pulmonary artery dissection
Incidence rate	high	rare
age	mostly children	mostly adults
Medical history	Mostly seen in PDA	chronic IPAH
Pulmonary pressure	normal or little high	high
Dilation of PA	normal or little wide	Yes
Echo view	mainly left high parasternal	Mainly aortic short-axis and pulmonary artery long-axis view
Location	changing with views	Fixed
CDFI	No interruption	Interruption with flow

PA: pulmonary artery; PDA: patent ductus arteriosus; IPAH: idiopathic pulmonary artery hypertension; CDFI: color Doppler flow imaging
