Key result
Angiographic right ventricular shortening fraction correlates strongly with RVEF across congenital and normal hearts.
Why the study?
Conventional methods of evaluating right ventricular function are inaccurate, cumbersome, and expensive, necessitating a simpler assessment method.
Does shortening fraction measured by biplane right ventricular angiography correlate with right ventricular ejection fraction in patients with congenital heart defects?
Observational (n=78)
Does shortening fraction measured by biplane right ventricular angiography correlate with right ventricular ejection fraction in patients with congenital heart defects?
Shortening fraction measured via biplane right ventricular angiography provides a simple method that correlates well with right ventricular ejection fraction in patients with congenital heart defects.

May simplify RV assessment in congenital heart disease; leaves open validation against reference standards.

Michael R. Nihill (2010) conducted an observational in Congenital Heart Defects (n=78). Biplane right ventricular angiography vs. Normal hearts was evaluated on Correlation of shortening fraction with right ventricular ejection fraction (r= 0.785). Shortening fraction measured by biplane right ventricular angiography correlated with right ventricular ejection fraction across patients with and without congenital heart defects (r=0.785).
