Glossary: report words, translated
Each entry gives a plain-language meaning and an honest "usually serious?" note. These are general descriptions for orientation - the same word can mean different things depending on size, combination, and context. Your team reads your report in its context.
- ASD atrial septal defect
- A hole between the two upper chambers. Small ones are common in the fetus and many close or shrink after birth. Often minor or self-resolving
- VSD ventricular septal defect
- A hole between the two pumping chambers. Significance depends almost entirely on size and position; many are small and some close spontaneously. Depends on size and position
- AVSD / AV canal atrioventricular septal defect
- A combined defect in the middle of the heart where the walls and valves meet. Usually needs surgery in infancy; often discussed with genetic testing. Usually significant - needs a specialist team
- Echogenic focus EIF, "golf ball"
- A bright spot of calcium-like density, most often in the left ventricle. In isolation it does not impair heart function; it is discussed because it slightly shifts statistical risk models. Usually benign in isolation
- Situs solitus normal arrangement
- The normal layout of heart and organs - the report saying "situs solitus" is a good, boring result. Normal finding
- Dextrocardia heart points right
- The heart points to the right instead of the left. Alone, with otherwise normal anatomy, it can be an innocent variation; with mirrored organs (situs inversus) or other defects it needs full assessment. Context decides - full echo needed
- Outflow tract LVOT / RVOT
- The pipelines each ventricle uses to send blood out - the aorta from the left, the pulmonary artery from the right. "Normal crossing" of these two is a key screening checkpoint. Anatomy term, not a diagnosis
- TOF tetralogy of Fallot
- A combination of four related findings centered on a VSD and a narrowed pulmonary outflow. One of the more common significant lesions; repaired surgically, usually in the first year. Severity varies widely. Significant - spectrum is wide
- TGA transposition of the great arteries
- The two great arteries are swapped, so the circuits don't connect the normal way. Needs planned delivery at a cardiac center; typically repaired surgically in the first weeks. Serious - requires specialized delivery planning
- HLHS hypoplastic left heart syndrome
- The left side of the heart is too small to do its job. One of the most serious lesions; delivered at specialist centers and treated with a staged series of operations. Outcomes have improved substantially but remain individually variable. Serious - long staged treatment
- Coarctation aortic narrowing
- A narrowing of the aorta after it leaves the heart. Suspected prenatally sometimes resolves, sometimes needs repair after birth; delivery at a cardiac-capable center is usually planned. Often needs postnatal care; spectrum wide
- Doppler flow study
- Ultrasound that shows blood-flow direction and speed. A technique, not a finding - "Doppler normal" is good news. Technique, not a diagnosis
- Rhythm - SINUS normal rhythm
- "Sinus rhythm" is the normal heart rhythm - the report noting it means the rhythm check was normal. Normal finding
- Tachycardia / bradycardia fast / slow rhythm
- A sustained heart rate above or below the normal fetal range. Some cases resolve with monitoring, some need treatment before birth; a genuine finding that goes to a rhythm specialist. Needs specialist follow-up
- "Suboptimal views" image-quality note
- Fetal position, movement, or maternal factors made some images hard to get. A statement about the pictures, not the heart. Usually means a repeat scan. About the images, not the baby
- Hydrops fluid accumulation
- Fluid collecting in the fetus (skin, abdomen, lungs), which can accompany severe heart strain. An important word that always warrants prompt specialist attention. Serious - prompt attention needed
- Nuchal translucency NT
- Fluid space at the back of the neck measured at 11-14 weeks. A larger NT modestly raises the chance of various findings including heart differences - one reason some echoes are scheduled early. A screening marker, not a diagnosis
Definitions follow the plain-language approach of ISUOG patient information and standard embryology texts; severity notes are general orientations, not case-specific judgments.
