Dynamic volume rendered three‐dimensional echocardiography allows the spatial recognition of anatomy and function of the aortic and mitral valves with acceptable image quality. The aortic valve can be best visualized in a view from the ascending aorta down to the valve level, thus allowing an overview of the aortic aspect of the valve in a surgeon's perspective in ∼ 80% of patients. Planimetric measurement of the aortic valve area was possible in 88% of patients, and there is no systematic overestimation or underestimation of aortic valve area compared with two‐dimensional echocardiography and catheterization. The entire valvular circumference of the mitral valve can be assessed from both a left atrial and a left ventricular perspective. Advantages of the three‐dimensional transesophageal echocardiography mitral valve area determination compared with transthoracic two‐dimensional planimetry and Doppler‐derived pressure half‐time method are present in patients with severely calcified mitral valves and in those with combined aortic regurgitation.
