What type of diuretic is commonly used in the medical management of congestion in mitral stenosis?

Loop diuretics are commonly employed in the medical management of congestion associated with mitral stenosis due to their potent diuretic effect. In mitral stenosis, the narrowing of the mitral valve leads to increased pressure in the left atrium and pulmonary circulation, which can cause pulmonary congestion and edema. Loop diuretics, such as furosemide (Lasix), are effective in quickly reducing fluid overload, alleviating symptoms like dyspnea and orthopnea by promoting significant diuresis.

These diuretics work by inhibiting the Na-K-2Cl symporter in the ascending loop of Henle in the kidney, leading to increased excretion of sodium, chloride, and water. This rapid fluid removal is particularly beneficial in acute settings where patients present with signs of heart failure or fluid overload.

While thiazide diuretics and potassium-sparing diuretics serve their roles in other conditions, they are not as effective in the management of acute pulmonary congestion seen in mitral stenosis. Carbonic anhydrase inhibitors primarily act on the proximal convoluted tubule and are not utilized for fluid overload conditions, making them less suitable in this scenario. Thus, loop diuretics are the preferred choice for managing
