Why the study?

Does real time three-dimensional echocardiography (RT3DE) in biplane mode accurately measure aortic valve area compared to TEE and TTE-CE in patients with aortic stenosis?

Population

41 patients with aortic stenosis (AS), mean age 73.5 +/- 8.2 years, 15 women and 26 men.

Comparison

Real time three-dimensional echocardiography in… vs Two-dimensional transesophageal echocardiography…

Design

Cross-sectional, Measured by two independent observers

Implication

RT3DE may support AVA assessment when TEE is limited; leaves open whether it improves outcomes versus TTE-CE in aortic stenosis.

Does real time three-dimensional echocardiography (RT3DE) in biplane mode accurately measure aortic valve area compared to TEE and TTE-CE in patients with aortic stenosis?

Population

41 patients with aortic stenosis (AS), mean age 73.5 +/- 8.2 years, 15 women and 26 men.

Intervention

Real time three-dimensional echocardiography (RT3DE) in biplane mode by planimetry

Comparator

Two-dimensional transesophageal echocardiography (TEE) planimetry and two-dimensional transthoracic echocardiography using the continuity equation (TTE-CE)

Outcome

Accuracy and feasibility of aortic valve area (AVA) assessmentsurrogate

RT3DE in biplane mode is a feasible and reproducible method for measuring aortic valve area in patients with aortic stenosis, correlating well with TEE and TTE-CE.
