Echocardiographic Evaluation Before Bidirectional Glenn Operation in Functional Single-Ventricle Heart Disease
Why the study?
Does echocardiographic evaluation accurately image vascular anatomy compared to cardiac catheterization in patients before bidirectional Glenn operation?
Population

Overview
Echocardiography should not replace catheterization for pre-Glenn vascular assessment; leaves open whether protocol optimization improves noninvasive accuracy.
Structured PICO
Does echocardiographic evaluation accurately image vascular anatomy compared to cardiac catheterization in patients before bidirectional Glenn operation?
P
Population
130 patients with functional single-ventricle heart disease presenting for bidirectional Glenn operation (BDG), median age 4 months, 55% with hypoplastic left heart syndrome.
I
Intervention
Echocardiographic evaluation
C
Comparator
Cardiac catheterization
O
Outcome
Accuracy of echocardiographic imaging of vascular anatomy (visualization of pulmonary arteries and aortic arch, and identification of stenoses)surrogate
Echocardiography frequently fails to adequately visualize pulmonary arteries and misses most stenoses, indicating it cannot replace cardiac catheterization as the sole pre-operative evaluation before bidirectional Glenn operation.
