  • Patent Foramen Ovale (PFO) [patent=open, foramen=opening] a hole between the two top chambers of the heart that is covered by a flap.  A cough, sneeze, or strain can cause this flap to open-–letting blood flow where it shouldn’t.
  • Pulmonary Atresia (pa) [pulmonary=having to do with the lungs, atresia=without openings] a complete blockage of the pulmonary artery (which carries blood from the heart to the lungs) caused by a missing or fused-shut pulmonary valve.
  • Tetralogy of Fallot is a combination of these four heart defects:
  1. Large Ventricular Septal Defect (VSD) [septum=wall between the chambers of the heart, ventricles=lower chambers of the heart] – holes in the inner walls of the heart allowing extra blood flow between the two lower chambers of the heart (ventricles). This causes the oxygen-rich and oxygen-poor blood to mix before leaving the heart.
  2. Enlarged Aorta (AO) that sits directly above the ventricular septal defect (VSD).  In a normal heart, the aorta carries oxygen-rich blood from the left ventricle to the body.
  3. Pulmonary  Stenosis (ps) [pulmonary=having to do with the lungs, stenosis=narrowing of a passage] – a narrowing of the pulmonary artery (which carries blood from the heart to the lungs) at or near the pulmonary valve.
  4. Right-Ventricular Hypertrophy [ventricles=lower chambers of the heart,hyper=excessive, trophy=condition of growth] thickening of the right-ventricular walls because the heart is working too hard.
  • left Pulmonary Artery Stenosis [pulmonary=having to do with the lungs, stenosis=narrowing of a passage] a narrowing of the left artery that carries oxygen-poor blood into the lungs.
  •  restrictive Ventricular Septal Defect (VSD) [septum=wall between the chambers of the heart, ventricles=lower chambers of the heart] multiple small holes in the inner wall of the heart between the two ventricles.

    Do you know anything about atrial situs solitus isolated ventricular inversion.EXTREAMLY rare

    1. I am familiar with the term, but have never met anyone who had it. It is incredibly rare! Do you have it or know someone who does? I am interested in hearing what other defects present with it in a specific instance.
