Objectives: To use echocardiographic dP/dt to assess the right ventricular function in patients with mitral stenosis. Subjects and methods: 48 patients with pulmonary hypertension due to mitral stenosis with everage age of 52.75 ± 13.09 years, were hospitalized in Department of Internal Cardiology and Cardiothoracic Department of Hue Central Hospital about time 3/2015 to 7/2017. All of patients had been measured right ventricular dP/dt index by Doppler echocardiograph. The method of research is a cross sectional study. Result: DP/dt should be reduced to the severity of pulmonary hypertension in patients with mitral stenosis. There was a statistically significant difference between right ventricular dP/dt of patients with mild to moderate systolic pulmonary hypertension with severe systolic pulmonary hypertension patients. There was a very negative correlation between right ventricular dP/dt rate and NYHA heart failure classification (r = -0.524 and p<0.0001), the negative correlation between right ventricular dP/dt and systolic pulmonary artery pressure (r = - 0.599 and p<0.0001). Positive correlation between right ventricular dP/dt and mitral valve area (r = 0.341 and p<0.05) and positive correlation between right ventricular dP/dt and TAPSE (r = 0.538 and p <0.001). Conclusion: dP/dt may be used to evaluate right ventricular function in patients with pulmonary hypertension due to mitral stenosis. Key words: Tricuspid Annular Plane Systolic Excursion (TAPSE), right ventrical dP/dt

Heart Size

Various parameters reflecting right heart size, right ventricular function and capacitance have been shown to be prognostically important in patients with pulmonary hypertension (PH). In the advanced disease, patients suffer from right heart failure, which is a main reason for an impaired prognosis. Right heart size has shown to be associated with right ventricular function and reserve and is correlated with prognosis in patients with PH. Right ventricular reserve, defined as the ability of the ventricle to adjust to exercise or pharmacologic stress, is expressed by various parameters, which may be determined invasively by right heart catheterization or by stress-Doppler-echocardiography as a noninvasive approach. As the term “right ventricular contractile reserve” may be misleading, “right ventricular output reserve” seems desirable as a preferred term of increase in cardiac output during exercise. Both right heart size and right ventricular reserve have been shown to be of prognostic importance and may therefore be useful for risk assessment in patients with pulmonary hypertension. In this article we aim to display different aspects of right heart size and right ventricular reserve and their prognostic role in PH.
