Right pulmonary artery originating from the Aorta

Parasternal long axis view showing dilation of the right ventricular outflow tract. Often pulmonary hypertension by reactive pulmonary vascular constriction in the lungs non-exposed to aortic pressure. The anterior sweep shows a normal pulmonary valve but a dilated pulmonary artery.

Parasternal long axis view. Colour box indicates that the right pulmonary artery is originating from the ascending aorta

Parasternal long axis view with colour box indicates that the right pulmonary artery originates from the ascending aorta.

Parasternal short axis view with colour box indicates that the right pulmonary artery originates from the ascending aorta and that the left pulmonary artery is at the continuation of the main pulmonary artery. The ductus looks restrictive and right to left.

Zoom over the Ductal view indicates that the PDA is small, restrictive (high velocity by Nyquist filter) and right to left. The left pulmonary artery is in continuation with the main pulmonary artery.

Ductal view without sweep indicates that the PDA is small, restrictive (high velocity by Nyquist filter) and right to left. The left pulmonary artery is in continuation with the main pulmonary artery.

Parasternal short axis with sweep. RVOT is dilated. The septum is bowing into the LV during systole. Dilated right ventricle in diastole and systole.

Parasternal short axis with sweep and colour. RVOT is dilated.

Apical view with sweep. RV is dilated. RV function is depressed. The Pulmonary artery originates from the RV and the Aorta originates from the LV.

Apical view with sweep and colour. RPA originates from the ascending Aorta. LPA originates from the pulmonary artery.

High parasternal short axis view with colour. LPA from the main pulmonary artery. RPA bifurcates from the Aorta.

Tricuspid regurgitant jet indicating 104 RV-RA gradient. BP at ECHO: 62/40.

Aortic arch and MPA sweep. MPA is branching with the PDA and the LPA.

Colour flow indicates retrograde flow in the descending aorta from possible diastolic steal effect in the right pulmonary artery.

Holodiastolic retrograde flow in the descending aorta by PW-Doppler.

Pulmonary insufficiency jet (CW-Doppler). End-diastolic velocity indicating at least 43 mmHg of MPA-RV gradient in diastole.

Prognosis is favorable. Require re-implantation of the right pulmonary artery to the main pulmonary artery under cardiopulmonary bypass. Occasional appearance of a stenosis at the origin of the re-implanted artery.
