What is Influence of Ejection Fraction and Valvular Regurgitation on the Accuracy of Aortic Valve Area Determination about?

Objective: To examine the influence of left ventricular dysfunction, aortic regurgitation, and mitral regurgitation on commonly used methods for aortic valve area (AVA) determination. Background: Each method for AVA determination has its inherent limitations. Methods: AVA determinations by transesophageal echocardiography (TEE) using planimetry, transthoracic echocardiography (TTE) with application of the continuity equation, and cardiac catheterization applying the Gorlin formula were performed in 74 patients with aortic stenosis. The severity of the aortic stenosis was defined by consensus of at least two methods. Over‐ or underestimation of AVA associated with ejection fraction, aortic regurgitation, mitral regurgitation, or severity of the aortic stenosis for each method in relation to the other two methods was assessed. Results: Mean AVAs were 1.05 ± 0.51 by TEE, 1.06 ± 0.51 by TTE, and 1.08 ± 0.53 by cardiac catheterization. An overestimation of the severity of the aortic stenosis by the Gorlin formula in patients with moderate‐to‐severe aortic regurgitation as compared to TEE‐derived data was found (P = 0.014). A similar trend of overestimation by catheterization in comparis
