Spectrum of pulmonary valve morphology and its relationship to pulmonary trunk in tetralogy of Fallot

Indian Journal of Radiology and Imaging, 2017
Background: Tetralogy of Fallot (TOF) is a complex congenital heart disease with anatomic variations. Although the pulmonary valve in TOF is abnormal, it has not been studied well, especially on newer imaging modalities such as multidetector computed ...

A geometric model for the human pulmonary valve in its fully open case. [PDF]

PLoS ONE, 2018
The human pulmonary valve, one of the key cardiac structures, plays an important role in circulatory system. However, there are few mathematical models to accurately simulate it. In this paper, we establish a geometric model of the normal human pulmonary
