Toronto 3D Heart Atlas

A growing collection of educational models created from cardiac-gated CT data of adult hearts, including from individuals with congenital heart disease. Segmentation: itk-SNAP and 3DSlicer. Textures: Blender.

This project is supported by the Department of Anesthesia and Pain Management, Joint Department of Medical Imaging, Adult Congenital Cardiac Clinic and The Division of Cardiac Surgery at Toronto General Hospital.

Financial support from the Peter Munk Cardiac Center Foundation at Toronto General Hospital, and a Continuing Professional Development Award from the Faculty of Medicine at the University of Toronto.

2018001-01 Tricuspid Atresia, Bjork Fontan

Diagnosis

  1. Hypoplastic right heart: tricuspid atresia, pulmonary stenosis, hypoplastic right ventricle
  2. Multiple VSDs
  3. Secundum ASD

Procedures

  1. Right-sided BTT shunt
  2. Bjork Fontan operation; ligation of BT shunt

2018002-01 Tetralogy of Fallot

Diagnosis

  1. Tetralogy of Fallot, (uncorrected): Overriding aorta, pulmonary stenosis, subaortic ventricular septal defect, right ventricular hypertrophy

Procedures

  1. Remnant of BTT shunt can be seen from left subclavian artery to left pulmonary artery.
  2. No further correction until age 65. Underwent pulmonary valve replacement subsequently.
2018003-02 Situs inversus, dextrocardia, transposition of great arteries – post insertion of RV-PA conduit

Diagnosis

  1. Orientation: Situs inversus totalis; dextrocardia; Infero-posterior morphologic LV, supero-anterior morphologic RV; Right aortic arch with mirror-image branching
  2. Segmental anatomy: Complex TGA: Concordant A-V, discordant V-A connections: posterior pulmonary valve, anterior aortic valve, with ventricular L-loop
  3. Shunts: Secondum ASD; Membranous VSD
  4. Pulmonary stenosis; subpulmonary outflow tract obstruction.

Procedures

  1. Patch closure of membranous VSD, tunnel-like connection of LV to aorta; pulmonary valvotomy and excision of fibrous tissue from the RVOT, closure of secundum ASD;
  2. Removal of VSD patch, Morrow-like incision on the ventricular septum; closure of VSD, Relief of subpulmonic outflow obstruction; transvenous atrial and ventricular pacemaker insertion

2018004-01 D-TGA post Atrial Switch Procedure (Mustard)

Diagnosis & Procedures

  1. D-TGA (AV concordance; VA discordance) post atrial switch (Mustard) repair.
  2. Large leak between IVC and pulmonary venous baffle.

2018005-01 Aortic atresia, Yasui repair

Diagnosis & Procedure

  1. Hypoplastic left heart; aortic atresia
  2. Ventricular septal defect.
  3. Yasui repair
