Purpose/ Objective

Borderline left ventricle is a challenging condition with limited data to guide management with regard to pursuing a biventricular repair vs univentricular circulation. What is the ideal state/ if the problem is gone? We would have multi modality imaging criteria that would accurately predict outcomes for a given patient if biventricular or univentricular approaches are pursued enabling us to make the right decision for each individual patient.

Following this session learners will understand:

1. It is feasible to assess patients with borderline LV with CMR

2. That LVEDVi assessed from echo is underestimated and a comprehensive CMR assessment would enable better patient selection to pursue biventricular approach.
