Overview

Severe acute AR requires emergency surgery if there are no absolute contraindications to surgery. The surgery should be performed as early as possible without a delay, particularly if hypotension, decreased perfusion, or pulmonary edema are present. In patients with chronic severe AR, mechanical or bioprosthetic valve may be used for valve surgery. In patients undergoing surgical replacement of the aortic sinuses and/or ascending aorta, maintaining of the native aortic valve (valve-sparing) may be possible in selected patients with favorable valve anatomy. Primary aortic valve repair is not yet generalizable, and durability is not known. AVR is recommended when there is LV dilation based on the measurement of LV in short-axis diameters. There are insufficient data on the relationship between LV volumes and outcomes of patients with AR.

Indications for Surgery for Acute Aortic Regurgitation

Timing of Emergency Surgery

Acute severe AR may cause death due to pulmonary edema, ventricular arrhythmias, electromechanical dissociation, or circulatory collapse. Individuals with bacteremia with aortic valve endocarditis should not wait for treatment with antibiotics to take effect, especially if there is hypotension, pulmonary edema, or low cardiac output given the high mortality associated with the acute AR.

Shown below is an algorithm for the treatment of acute AR.[1]

Type of Surgery

Replacement with an aortic valve homograft should be performed if feasible. The surgical approach depends upon the cause of AR. Aortic valve replacement or repair may be needed in cases of valvular structural abnormalities and aortic root repair/replacement may be needed in cases of aortic dissection.

Preoperative Medical Therapy

Patients may be temporarily managed before surgery with vasodilators such as nitroprusside and possibly inotropic agents such as dopamine or dobutamine to improve stroke volume and reduce left ventricular end-diastolic pressure.[4] Intra-aortic balloon pump is contraindicated as this would worsen aortic regurgitation by increasing afterload due to the inflation of the balloon during diastole.[5]

Mild Acute AR in the Setting of Aortic Dissection

In mild AR secondary to aortic dissection, the aortic valve can be repaired/replaced at the time of surgery for aortic dissection.

    The above algorithm adopted from 2021 ESC Guideline[6]



    Recommendations for surgery in severe aortic regurgitation and aortic root or tubular ascending aortic aneurysm
    Severe aortic regurgitation (Class I, Level of Evidence B):

    Surgery is recommended in symptomatic patients regardless of LV function
    Surgery is recommended in asymptomatic patients with LVESD > 50 mm or LVESD > 25 mm/m2 BSA (in patients with small body size) or resting LVEF ≤ 50%

    (Class IIb, Level of Evidence C):

    Surgery may be considered in asymptomatic patients with LVESD >20 mm/m2 BSA (especially in patients with small body size) or resting LVEF ≤ 55%, in low risk condition
    ❑Aortic valve repair may be considered in selected patients at experienced centres when durable results are expected

    (Class I, Level of Evidence C) :

    Surgery is recommended in symptomatic and asymptomatic patients with severe aortic regurgitation undergoing CABG or surgery of the ascending aorta or of another valve

    Aortic root or tubular ascending aortic aneurysmc (irrespective of the severity of aortic regurgitation (Class I, Level of Evidence B):

    Valve-sparing aortic root replacement is recommended in young patients with aortic root dilation

    (Class I, Level of Evidence C):

    ❑ Ascending aortic surgery is recommended in patients with Marfan syndrome and ascending aortic diameter ≥ 50 mm

    (Class IIa, Level of Evidence C):

    ❑ Ascending aortic surgery is recommended with ascending aorta size of:

    Risk factors: family history of aortic dissection (or personal history of spontaneous vascular dissection), severe aortic or mitral regurgitation, desire for pregnancy, uncontrolled systemic arterial hypertension , aortic size increase >3 mm/year

    ❑ In the presence of primarily indication for the surgery of aortic valve, replacement of the aortic root or tubular ascending aorta should be considered when ≥ 45 mm
