Patient Population
A total of 43 patients considered for transcatheter valve implantation procedure were prospectively included in the present study. Patients with history of mitral valve repair or replacement were excluded. All patients underwent a routine preoperative two-dimensional transthoracic echocardiography (TTE) to assess left ventricular and valvular function. The MDCT was performed to evaluate aortic and mitral valve anatomy before the intervention. In addition, TEE was performed routinely during the
Results
In all, 43 patients (mean age 81.0 ± 7.7 years; 60% men) were evaluated. Clinical and two-dimensional TTE characteristics of the patients are described in Table 1. Mean height, weight, and body mass index were 170.8 ± 7.6 cm, 75.1 ± 10.7 kg, and 25.7 ± 3.4 kg/m2, respectively.
Variable degrees of mitral regurgitation were present in 88.4% of patients, with 48.9% of the patients showing moderate or severe mitral regurgitation (Table 1). The average heart rate during TEE was 66.7 ± 13.3 beats per
Comment
The present study demonstrates that three-dimensional TEE allows for an accurate analysis of the mitral valve geometry as compared with the anatomical reference standard MDCT. In addition, three-dimensional TEE derived measurements were highly reproducible with good intraobserver and interobserver agreements. These findings indicate that three-dimensional TEE and MDCT may be complementary imaging tools to evaluate the mitral valve anatomy and geometry.
