Which of the following statement about the pathophysiology of mitral stenosis is accurate
Correct Answer: Patients with mitral stenosis generally have an under-loaded left ventricle.
Description: 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.
