Which of the following statement about the pathophysiology of mitral stenosis is accurate

The pathophysiology of mitral stenosis involves impaired diastolic filling of the left ventricle because of an obstruction at the level of the mitral valve. This results in a pressure gradient between the left atrium and the left ventricle. Consequently, left atrial pressure rises while the left ventricle is under-filled. As left atrial pressure increases, pulmonary venous return is impaired and pulmonary hypeension with right ventricular failure can occur.
