Good Agreement

The aim of this study is to evaluate the agreement between three-dimensional (3D) transesophageal echocardiography (TEE) and multidetector computed tomography (MDCT) for assessing mitral annular (MA) dimensions. A total of 105 patients (79 ± 9 years old, 52% male) who underwent clinically indicated 3D TEE and MDCT feasible for MA geometrical assessment were included. Using dedicated semi-automated postprocessing software, MA geometry, including mitral annular area (MAA), perimeter, septal-lateral (SL) diameter, and inter-trigonal (TT) diameter, was evaluated using 3D TEE and MDCT. Compared to 3D TEE, MAA, perimeter, and SL distance measured on MDCT data were larger (9.9 ± 3.0 vs. 9.3 ± 3.1 cm2 for MAA; 115 ± 18 vs. 108 ± 18 mm for perimeter; and 35 ± 5 vs. 32 ± 5 cm for SL distance, all p < 0.001). By contrast, the TT distance was comparable between MDCT and 3D TEE (26 ± 4 vs. 26 ± 4 cm, p = 0.258). The correlations of all the MA dimensions were good to excellent between the two modalities (R = 0.911 for MAA, 0.890 for perimeter, 0.739 for TT distance, and 0.857 for SL distance, respectively, all p < 0.001). This study showed good agreement between 3D TEE- and MDCT-derived MA measurements although MDCT systematically provided larger MAA, perimeter, and SL distance compared with 3D TEE.

Aim. To compare effectiveness of ultrasound, radiological and invasive methods for assessing aortic valve (AV) stenosis.Material and methods. This study included 33 patients with AV stenosis. The mean age of the patients was 71,8±6,8 years. All patients underwent standard and three-dimensional echocardiography, computed tomography, and cardiac catheterization.Results. According to two-dimensional echocardiography, the AV area averaged 0,58±0,21 mm2, according to cardiac catheterization — 0,61±0,17 mm2, according to three-dimensional transesophageal echocardiography — 1,13±0,42 mm2, and according to multislice computed tomography 0,88±0,48 mm2. The difference between the values was significant (p<0,05).Conclusion. For routine diagnosis of AV stenosis, two-dimensional echocardiography is the optimal research method. With indications for radical treatment methods, three-dimensional echocardiography or multislice computed tomography should be performed.

Three Dimensional Echocardiography

Jelenleg az echokardiográfia a legszéleskörűbben alkalmazott rutin noninvazív diagnosztikus eljárás, amelynek segítségével a mitralis billentyű morfológiája és funkciója jellemezhető. Ennek az összefoglaló jellegű közleménynek a célja az egyik legújabb echokardiográfiás fejlesztés, a transthoracalis real-time háromdimenziós echokardiográfia szerepének bemutatása a mitralis billentyű vizsgálatában.
