Severe acute [[AR]] requires emergency surgery | Severe acute [[AR]] requires emergency [[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]]. | |||

*[[Symptoms]] is an important indication for [[AVR]] in [[patients]] with chronic severe [[AR]]. | |||
* Taking a careful, detailed history regarding [[symptoms]] or reduced [[exercise capacity]] is important. | |||
* [[AVR]] results in an improved [[survival rate]] even among [[symptomatic]] [[patients]] with a severe reduction in [[LVEF]] (<35%). <ref name="pmid10199882">{{cite journal |vauthors=Dujardin KS, Enriquez-Sarano M, Schaff HV, Bailey KR, Seward JB, Tajik AJ |title=Mortality and morbidity of aortic regurgitation in clinical practice.

* [[LV]] [[systolic function]] is an important determinant of [[survival]] and [[functional status]] after [[AVR]]. | |||
* Optimal outcome reaches when [[AVR]] is performed before [[LVEF]] decreases below 55% or before the onset of [[symptoms]].<ref name="pmid7377109">{{cite journal |vauthors=Forman R, Firth BG, Barnard MS |title=Prognostic significance of preoperative left ventricular ejection fraction and valve lesion in patients with aortic valve replacement |journal=Am J Cardiol |volume=45 |issue=6 |pages=1120–5 |date=June 1980 |pmid=7377109 |doi=10.1016/0002-9149(80)90468-3 |url=}}</ref> <ref name="pmid17397676">{{cite journal |vauthors=Bhudia SK, McCarthy PM, Kumpati GS, Helou J, Hoercher KJ, Rajeswaran J, Blackstone EH |title=Improved outcomes after aortic valve surgery for chronic aortic regurgitation with severe left ventricular dysfunction |journal=J Am Coll Cardiol |volume=49 |issue=13 |pages=1465–71 |date=April 2007 |pmid=17397676 |doi=10.1016/j.jacc.2007.01.026 |url=}}</ref> | |||
* Other types of [[cardiac surgery]], such as [[CABG]], [[mitral valve]] surgery, or [[surgery]] for correction of dilation of the [[aortic root]] or [[ascending aorta]] can be performed at the time of [[AVR]]. | |||
*[[LVESD]] in [[patients]] with chronic [[AR]] indicates both the severity of the [[LV ]] [[volume overload]] and the degree of [[LV systolic]] shortening.<ref name="pmid3779916">{{cite journal |vauthors=Carabello BA, Williams H, Gash AK, Kent R, Belber D, Maurer A, Siegel J, Blasius K, Spann JF |title=Hemodynamic predictors of outcome in patients undergoing valve replacement |journal=Circulation |volume=74 |issue=6 |pages=1309–16 |date=December 1986 |pmid=3779916 |doi=10.1161/01.cir.74.6.1309 |url=}}</ref> | |||
* An elevated [[LVESD]] shows [[LV]] [[systolic dysfunction]] with a depressed [[LVEF]]. If [[LVEF]] is normal, increased [[LVESD]] indicates a significant degree of [[LV]] remodeling resulting development of [[symptoms]] and/or [[LV systolic dysfunction]] and an increased [[mortality rate]] after [[AVR]].<ref name="pmid2972417">{{cite journal |vauthors=Bonow RO, Dodd JT, Maron BJ, O'Gara PT, White GG, McIntosh CL, Clark RE, Epstein SE |title=Long-term serial changes in left ventricular function and reversal of ventricular dilatation after valve replacement for chronic aortic regurgitation |journal=Circulation |volume=78 |issue=5 Pt 1 |pages=1108–20 |date=November 1988 |pmid=2972417 |doi=10.1161/01.cir.78.5.1108 |url=}}</ref> | |||
* [[Body size]] index is important, especially in [[women]] or small [[patients]]. | |||
* [[LV volumes]] may be a more sensitive predictor of [[cardiac]] events than [[LVESD]] index in asymptomatic [[patients]]. | |||
*In [[patients]] with moderate [[AR]] who are undergoing other forms of [[cardiac surgery]], such as [[CABG]], [[mitral valve]] [[surgery]], or replacement of the [[ascending aorta]], consideration of [[aortic valve]] anatomy, [[aortic]] root size and shape, [[regurgitant]] severity, other [[comorbidities]], and [[patient]]'s preferences and values is recommended. | |||
*[[Valve]]-sparing procedure may be considered in [[patients]] undergoing [[surgical]] repair or replacement of the [[aortic root]] or [[ascending aorta]]. | |||
*In asymptomatic [[patients]] with chronic [[AR]], [[LVEDD]] is a marker of the severity of [[LV]] volume overload and associated with clinical [[outcomes]] , and progressive increases in [[LVEDD]] are associated with a further need for [[surgery]].<ref name="pmid25813142">{{cite journal |vauthors=Zhang Z, Yang J, Yu Y, Huang H, Ye W, Yan W, Shen H, Ii M, Shen Z |title=Preoperative ejection fraction determines early recovery of left ventricular end-diastolic dimension after aortic valve replacement for chronic severe aortic regurgitation |journal=J Surg Res |volume=196 |issue=1 |pages=49–55 |date=June 2015 |pmid=25813142 |doi=10.1016/j.jss.2015.02.069 |url=}}</ref> | |||
*[[TAVI]] for isolated chronic [[AR]] is challenging because of dilation of the [[aortic]] annulus and [[aortic]] root and lack of sufficient leaflet [[calcification]].<ref name="pmid28521923">{{cite journal |vauthors=Sawaya FJ, Deutsch MA, Seiffert M, Yoon SH, Codner P, Wickramarachchi U, Latib A, Petronio AS, Rodés-Cabau J, Taramasso M, Spaziano M, Bosmans J, Biasco L, Mylotte D, Savontaus M, Gheeraert P, Chan J, Jørgensen TH, Sievert H, Mocetti M, Lefèvre T, Maisano F, Mangieri A, Hildick-Smith D, Kornowski R, Makkar R, Bleiziffer S, Søndergaard L, De Backer O |title=Safety and Efficacy of Transcatheter Aortic Valve Replacement in the Treatment of Pure Aortic Regurgitation in Native Valves and Failing Surgical Bioprostheses: Results From an International Registry Study |journal=JACC Cardiovasc Interv |volume=10 |issue=10 |pages=1048–1056 |date=May 2017 |pmid=28521923 |doi=10.1016/j.jcin.2017.03.004 |url=}}</ref> | |||
* Risks of [[TAVI]] for treatment of [[AR]] include transcatheter valve migration and significant paravalvular [[leak]]. | |||
* [[TAVI]] is rarely feasible, and [[transcatheter]] approach may be performed in the [[selected]] [[patients]] with severe [[AR]] and [[HF]], high [[surgical]] risk , with [[valvular]] [[calcification]] and appropriate [[annular]] size. | |||

Overview
Severe acute AR requires emergency 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]
Abbreviations: AVR: Aortic valve replacement; ACE: Angiotensin converting enzyme; ARB: Angiotensin receptor blocker; CCB: Calcium channel blocker; LVEF: Left ventricle ejection fraction; TTE: Transthoracic echocardiography
What is the cause of acute AR? | |||||||||||||||||||||||||||||
Infective endocarditis | Aortic dissection | ||||||||||||||||||||||||||||
Does the patient have AR related heart failure symptoms? | ❑ Schedule for an emergent surgery[2] ❑ Administer beta blockers with caution (beta blockers inhibit compensatory tachycardia) | ||||||||||||||||||||||||||||
Yes | No | ||||||||||||||||||||||||||||
❑ Schedule for early aortic valve replacement (Class I, level of evidence B)[3] | |||||||||||||||||||||||||||||
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.
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[6]
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. 1-4 In individuals with acute severe AR, intra-aortic balloon counterpulsation is not recommended.
Indications for Surgery for Chronic Aortic Regurgitation
Notes
- Symptoms is an important indication for AVR in patients with chronic severe AR.
- Taking a careful, detailed history regarding symptoms or reduced exercise capacity is important.
- AVR results in an improved survival rate even among symptomatic patients with a severe reduction in LVEF (<35%). [7]
- LV systolic function is an important determinant of survival and functional status after AVR.
- Optimal outcome reaches when AVR is performed before LVEF decreases below 55% or before the onset of symptoms.[8] [9]
- Other types of cardiac surgery, such as CABG, mitral valve surgery, or surgery for correction of dilation of the aortic root or ascending aorta can be performed at the time of AVR.
- LVESD in patients with chronic AR indicates both the severity of the LV volume overload and the degree of LV systolic shortening.[10]
- An elevated LVESD shows LV systolic dysfunction with a depressed LVEF. If LVEF is normal, increased LVESD indicates a significant degree of LV remodeling resulting development of symptoms and/or LV systolic dysfunction and an increased mortality rate after AVR.[11]
- Body size index is important, especially in women or small patients.
- LV volumes may be a more sensitive predictor of cardiac events than LVESD index in asymptomatic patients.
- In patients with moderate AR who are undergoing other forms of cardiac surgery, such as CABG, mitral valve surgery, or replacement of the ascending aorta, consideration of aortic valve anatomy, aortic root size and shape, regurgitant severity, other comorbidities, and patient's preferences and values is recommended.
- Valve-sparing procedure may be considered in patients undergoing surgical repair or replacement of the aortic root or ascending aorta.
- In asymptomatic patients with chronic AR, LVEDD is a marker of the severity of LV volume overload and associated with clinical outcomes , and progressive increases in LVEDD are associated with a further need for surgery.[12]
- TAVI for isolated chronic AR is challenging because of dilation of the aortic annulus and aortic root and lack of sufficient leaflet calcification.[13]
- Risks of TAVI for treatment of AR include transcatheter valve migration and significant paravalvular leak.
- TAVI is rarely feasible, and transcatheter approach may be performed in the selected patients with severe AR and HF, high surgical risk , with valvular calcification and appropriate annular size.
