Toronto 3D Heart Atlas – The Lynn & Arnold Irwin Advanced Perioperative Imaging Lab

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 a collaboration by the Department of Anesthesia and Pain Management, Joint Department of Medical Imaging, Adult Congenital Cardiac Clinic, Electrophysiology, and The Division of Cardiac Surgery at Toronto General Hospital. Financial support from the UHN Foundation, and a Continuing Professional Development Award from the Faculty of Medicine at the University of Toronto.
Developed by: Azad Mashari MD, Joshua Qua Hiansen MSc, Kate Kazlovich, Ryan Ramos MD, Sachin Khargie, Mini Pakkal MD, Eitan Aziza MD, Massimiliano Meineri MD
A special thanks to Drs. M. Osten, E. Horlick, E. Hicky, K. Nair and RJ Cusimano for their support of the project.

Toronto Heart Atlas by APIL on Sketchfab

2018001-01 Tricuspid Atresia, Bjork Fontan

Diagnosis

Hypoplastic right heart: tricuspid atresia, pulmonary stenosis, hypoplastic right ventricle
Multiple VSDs
Secundum ASD

Procedures

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

Diagnosis

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

Procedures

Remnant of BTT shunt can be seen from left subclavian artery to left pulmonary artery.
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

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

Procedures

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;
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
