JCMR 2021; 23:51. False lumen pressure estimation in Type B aortic dissection using 4D flow cardiovascular magnetic resonance: comparisons with aortic growth (CME)


This manuscript investigate the ability of several novel 4D Flow MRI derived metrics of false lumen pressurization to predict aortic growth among patients with type B aortic dissection. In this paper we described the advantages and disadvantages of different hemodynamic metrics and propose conceptual model of how these metrics relate to aortic growth and false lumen pressure.


What is the current state/problem in practice? Growth of the false lumen is poorly predicted by current anatomic metrics such as maximal aortic diameter. What is the ideal state/ if the problem is gone? Non-invasive imaging techniques can be used to accurately predict future growth and complications in patients with type B dissection to allow for improved management decisions.


This paper aims to help readers better understand the complex relationships between blood flow abnormalities and pressure in the false lumen in type B dissection and how different metrics can be used to estimate aortic growth.


Learning Objective

To close the gap outlined above, learners 'need' to:

1. Understand hemodynamic abnormalities in the false lumen of patients with type B aortic dissection

2. Know how to apply 4D Flow MRI to assess aortic hemodynamics in type B aortic dissection.
