Tutorial

Atrial Septal Defect (ASD)

ASD subtypes and true nomenclature, echo diagnosis and Qp:Qs calculation, contrast/TEE technique, and current closure criteria and devices.

Tutorial

Ventricular Septal Defect (VSD)

Modern border-based VSD classification, echo diagnosis, RVSP estimation from the VSD jet, and current closure criteria including special circumstances.

Tutorial

Patent Ductus Arteriosus (PDA)

Closure timing nuance, the three ductal Doppler flow patterns, hemodynamically-significant-PDA criteria, and distinguishing PDA flow from aortic regurgitation.

Tutorial

Coarctation of the Aorta

Why 'pre-ductal/post-ductal' oversimplifies the anatomy, the diastolic run-off Doppler sign, the corrected-gradient formula, and Turner syndrome association.

Tutorial

Pulmonary Valve Stenosis

Doming vs. dysplastic valve morphology and treatment implications, the standard severity thresholds, and diagnostic pitfalls in pulmonary stenosis.

Tutorial

Atrioventricular Septal Defect (AVSD)

The common AV junction, five-leaflet valve anatomy, Rastelli classification, and RVSP estimation for partial, transitional, and complete AVSD.

Tutorial

Tetralogy of Fallot (TOF)

The single unifying anatomic mechanism behind TOF's four features, multilevel RVOT obstruction, key associated anomalies, and the postoperative echo checklist.

Tutorial

Ebstein's Anomaly

Failed leaflet delamination, the displacement and Celermajer indices, TR-quantification pitfalls, and the modern cone repair for Ebstein's anomaly.

Tutorial

Transposition of the Great Arteries (TGA)

Why 'D-TGA' is a nonspecific term to avoid, the segmental definition that actually matters, coronary pattern risk, and arterial vs. atrial switch follow-up.

Tutorial

Congenitally Corrected Transposition of the Great Arteries (ccTGA)

Why 'L-TGA' is an outdated, sometimes flatly wrong label, the double-discordance definition, the correct valve-continuity anatomy, and heart block risk.

Tutorial

Tricuspid Atresia

Absent AV connection vs. imperforate valve, the Tandon-Edwards classification with type-specific therapy, and the staged Fontan pathway.

Tutorial

Truncus Arteriosus (Common Arterial Trunk)

Two classification systems that reuse the same numerals for different things, the 22q11/interrupted arch associations, and truncal valve morphology.

Tutorial

Pulmonary Venous Anomalies

How to image the pulmonary veins by echo, the anatomic spectrum from abnormal vein number to TAPVC, and how to diagnose each anomaly and its obstruction.

Tutorial

Systemic Venous Anomalies

How to image the SVC, IVC, coronary sinus, hepatic and innominate veins by echo, their congenital anomalies, and why each matters before surgery.

Tutorial

Coronary Arteries: Imaging, Anomalies, and Kawasaki Disease

Echo views for the coronary arteries, how to diagnose ALCAPA, AAOCA, fistulas and other anomalies, and how to assess coronary involvement in Kawasaki disease.

Tutorial

Eisenmenger Syndrome

The specific 'Eisenmenger-type VSD,' the Qp:Qs>2:1 progression threshold, why vasodilator therapy can harm the wrong PH type, and shunt-specific risk.
