Pulmonary valve stenosis is when the heart’s pulmonary valve is thicker and smaller than normal, leading to improper blood flow from the heart to the lungs.
Pulmonary atresia with ventricular septal defect (PA/VSD) is a hole between the heart's two bottom chambers and no connection to the lung's blood arteries.
Congenital heart valve abnormalities may result from valves that aren’t fully formed or are the wrong size or shape from birth, which may restrict blood flow.
D-transposition of the great arteries (D-TGA) is a form of congenital heart disease (CHD) that results when the aorta and pulmonary arteries are switched.
Patent ductus arteriosus (PDA) is when a blood vessel that's critical to blood circulation pre-birth, but unnecessary post-birth, doesn’t close as it should.
In Ebstein’s anomaly, the tricuspid valve (the gate between the heart's upper and lower right chambers) is abnormally developed, which may hinder blood flow.
Hypoplastic left heart syndrome (HLHS) is when the heart’s main pumping chamber (the left ventricle) and left-sided valves (mitral, aortic) develop poorly.
L-transposition of the great arteries (L-TGA) is when blood circulation flows correctly, but serious problems may still exist or develop and require treatment.
