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.
