This document discusses diagnostic and surgical treatment options for mitral valve stenosis. It presents the case of a 46-year-old female patient with severe mitral stenosis who has not responded well to pharmacological treatment. Two main surgical interventions are considered: balloon mitral valvuloplasty and mitral valve annuloplasty. Studies are presented showing that valvuloplasty can improve left ventricular function and strain, while annuloplasty may be associated with higher gradients and worse quality of life. Based on the patient's history and characteristics, the document recommends valvuloplasty as it allows for variable improvement in health compared to mitral surgery, which carries a higher risk of compromising health. Close monitoring is still advised
