Overview

In patients with acute severe AR resulting from infectious endocarditis or aortic dissection, reduction LV afterload by medications may be a temporary stabilization, but surgery should not be delayed, especially in the presence of hypotension, pulmonary edema, or evidence of low flow. Intra-aortic balloon counterpulsation is contraindicated in patients with acute severe AR. Beta blockers are often used in treating aortic dissection. However, these agents should be used very cautiously because of block the compensatory tachycardia and reduction in blood pressure.

Medical Therapy

Therapeutic Options

Nitroprusside

Nitroprusside lowers afterload and thereby reduces retrograde flow and left ventricular end diastolic pressure.[2]

Inotropic Agents

Inotropic agents such as dopamine and dobutamine can be used to increase the contractility of the heart resulting in improved forward flow.[3]

Beta Blockers

Beta blockers which are often used in managing aortic dissection should be used very cautiously in the presence of acute AR as beta blockers can block the compensatory tachycardia and worsen the cardiac output.

Intraaortic Balloon Pump

Insertion of an intraaortic balloon pump is contraindicated in acute AR, as it may worsen the severity of the regurgitation.[4]

2020 ACC/AHA Guideline for the Management of Patients With Valvular Heart Disease A Report of the American College of Cardiology/American Heart Association Joint Committee on Clinical Practice Guidelines[5]

Medical treatment to lower LV afterload may temporarily stabilize patients with acute severe AR brought on by IE or aortic dissection, but surgery should not be postponed, especially if there is hypotension, pulmonary edema, or indications of low flow.


Aortic dissection is frequently treated with beta-blockers. However, these medications should only be used very sparingly, if at all, for other acute AR reasons because they will prevent compensatory tachycardia and may induce a significant drop in blood pressure.
