Tetralogy of Fallot I-371

3D Model

Specimen with tetralogy of Fallot.

A group of congenital cardiac malformations with biventricular atrioventricular alignments or connections characterized by anterosuperior deviation of the conal or outlet septum or its fibrous remnant, narrowing or atresia of the pulmonary outflow, a ventricular septal defect of the malalignment type, and biventricular origin of the aorta. Tetralogy of Fallot will always have a ventricular septal defect, narrowing or atresia of the pulmonary outflow, aortic override, and most often right ventricular hypertrophy.

The interventricular communication is an outlet defect as it lives within the “Y” of the septal band (between the cranial and caudal limbs of the septomarginal trabeculation).

The pulmonary valve has 2 leaflets and 2 sinuses.

IPCCC classification (01.01.01).

Scanned with Revopoint Miraco.
