• Subcostal color compare of the atrial septum revealing a small restrictive PFO with left to right shunting

• Spectral Doppler across a PFO revealing restriction with an elevated mean gradient of 11 mmHg

DILV with normally related great arteries (D-looped/right-handed ventricular topology aka Holmes heart)

• Subcostal color compare sweep demonstrating an anterior and rightward subpulmonary outlet chamber with normally related great arteries

• Flow is seen into the hypoplastic RV chamber through a VSD

• Pulmonary artery seen arising from hypoplastic right-sided RV chamber

• Aorta seen arising from the left ventricle at the end of the sweep anteriorly (normally related great arteries)

• Subcostal sweep demonstrating parallel great arteries with the aorta anterior and leftward (L-TGA)
• The anterior leftward aorta arises from a small anterior leftward subaortic hypoplastic RV cavity (seen at end of sweep)
• The pulmonary artery arises posteriorly from the LV
• There appear to be chordal attachments seen protruding into the subpulmonary region across the VSD

• Subcostal color sweep demonstrating parallel great arteries with the aorta anterior and leftward (L-TGA)
• The anterior leftward aorta arises from a small anterior leftward subaortic hypoplastic RV cavity (seen at end of sweep)
• The pulmonary artery arises posteriorly from the LV
• There appears to be laminar flow across the VSD into the hypoplastic RV chamber and out the aorta (at end of sweep)
• There appear to be mild flow turbulence seen starting at the subpulmonary region near where chordal attachments are seen protruding beneath the pulmonary valve 

• Small anterior leftward subaortic hypoplastic RV cavity 
• The pulmonary artery arises posteriorly from the LV
• AV valve chordae seen crossing the VSD
• Laminar flow across the VSD
• Mild flow turbulence if noted which begins in the subpulmonary region
