Background: In mitral stenosis (MS), the international recommendations are favor the mitral dilation if mean transmitral gradient reaches 15 mmHg or greater at the peak exercise Doppler echocardiography (grade C). Objective: Study of the transmitral gradient during exercise Echocardiography in patient with mitral valve area (MVA) of ≤ 2 cm2. Results: 300 patients were included. The mean age was 42.7 ± 1.3 years, the sex ratio of 0.23. According to the MVA, three groups were defined. G1 (severe MS): MVA ≤ 1cm2 (n =72), G2 (moderate MS): 1cm2 < MVA < 1.5cm2 (n = 128) and G3 (mild MS): MVA ≥ 1.5 cm2 (n = 100). The mean MVA was 0.8 ± 0.1 cm2 (G1), 1.3 ± 0.1 cm2 (G2) and 1.7 ± 0.1 cm2 (G3) (p < 10-6). At rest, from the 1st to the 3rd group, mean heart rate/min was respective.. Read More»
