Presented at: American College of Cardiology Scientific Session; March 17-19, 2017; Washington, D.C. Yoon SH, et al. J Am Coll Cardiol. 2017;doi:10.1016/j.jacc.2017.03.017. Disclosure: Yoon reports no relevant financial disclosures. [healio.com]
Conclusions Male patients with BAV present more frequently with ≥moderate AR at first presentation whereas female present more frequently with ≥moderate AS. Furthermore, diffuse dilatation of the aorta was more prevalent in male. [onlinejacc.org]
Cystic medial necrosis present in the aneurysmal wall probably arose as a consequence of poststenotic dilatation. [jhu.pure.elsevier.com]
Failure to present until clinical symptoms develop—either because the murmur is not detected or is lost to follow-up—can have important consequences. [bmj.com]

This arrangement is much more common in patients with coarctation of the aorta, whose valves function adequately. [emedicine.medscape.com]
The bicuspid aortic valve is associated with abnormalities of the aortic wall such as coarctation of the aorta, aortic dissection, and aortic aneurysm. Most patients with a bicuspid aortic valve will develop some complication during life. [ncbi.nlm.nih.gov]
Therefore, if the patient needs surgery, the size of the aorta will determine what type of surgery should be offered to the patient. [3] Associated Congenital Heart Disease Patients with bicuspid aortic valve are also at higher risk of aortic coarctation [wikidoc.org]

- Heart Murmur
The main sign of heart valve disease is an unusual heartbeat sound called a heart murmur. Your doctor can hear a heart murmur with a stethoscope. But many people have heart murmurs without having a problem. [icdlist.com]
A heart murmur was noted during that consultation but not followed up. He later recalled that as a child he underwent annual review for a heart murmur. At age 16 he was reassured and discharged from clinic. [bmj.com]
Get your heart murmur checked People with heart murmurs are at an increased risk of an aortic valve disease called bicuspid aortic valve disease. [pennmedicine.org]
A patient with a bicuspid aortic valve usually comes to attention due to the presence of a heart murmur or an abnormal heart sound. There are many other different causes of heart murmurs, including normal causes. [pediatricheartspecialists.com]
- Systolic Murmur
An attenuation of systolic murmur also occurred. No aortic diastolic murmur was detected. [jpgmonline.com]

The phenomenon known as pulsus parvus et tardus refers to a weak (parvus) and delayed (tardus) carotid upstroke. To asses for parvus, it is often helpful to palpate one’s own carotid artery while concurrently palpating the patient’s carotid artery. [healio.com]
A pulsus parvus et tardus (the arterial pulse is slow to increase and has a reduced peak) can be appreciated by palpating the carotid pulse of patients with severe aortic stenosis. [textbookofcardiology.org]

Neurologic
- Dizziness
Symptoms of a stenotic valve include chest pain, shortness of breath and dizziness or fainting caused by inadequate blood flow to the brain. If the bicuspid valve does not close completely, blood can flow backwards into the heart. [my.clevelandclinic.org]
Although some people with a bicuspid valve are asymptomatic, common symptoms include: Shortness of breath Constant tiredness or fatigue Coughing at night or when in bed Rapid or fluttering heart palpitations Dizziness Chest pain (tightness, angina) Fainting [healthblog.uofmhealth.org]
Should a child develop moderate or severe tightness (aortic stenosis) or leaking (aortic regurgitation), or severe dilation of the ascending aorta, he or she might show signs of shortness of breath, exercise intolerance, fatigue, chest pain, dizziness [childheartassociates.com]

Workup
The size of the proximal aorta should be evaluated carefully during the workup. [en.wikipedia.org]
Diagnosis of aortic stenosis is suspected on physical examination (abnormal heart sounds, abnormalities in the pulse) and confirmed by echocardiography. 2,9 (For a detailed description of the history, physical examination, differential diagnosis, and workup [uspharmacist.com]
X-Ray
- Calcified Aortic Valve
In young patients with congenital forms of aortic stenosis, valvulotomy is often a good option. Unfortunately, in older people with heavily calcified aortic valves, the results with valvulotomy have not been good. [verywell.com]
On transthoracic echocardiogram, the parasternal short-axis view showed a calcified aortic valve with probable bicuspid morphology (panel A). [tandfonline.com]

Rare initial symptoms in a patient with aortic stenosis include embolic phenomenon from calcified aortic valve plaques or massive GI bleeding due to angiodysplasia (Heyde’s syndrome). [healio.com]
Hypertrophy
- Left Ventricular Hypertrophy
Left ventricular hypertrophy is present in bicuspid aortic stenosis. [5] Pathological Findings Images shown below are courtesy of Professor Peter Anderson DVM PhD [6] and published with permission. [wikidoc.org]
If there are signs of left ventricular hypertrophy (thickening of the ventricle walls) or arrhythmia in conjunction with moderate stenosis, then the patient should be confined to moderate levels of isotonic exercise and should avoid isometric exercise [pted.org]
A S4 heart sound is also often present due to the severe concentric left ventricular hypertrophy that develops in aortic stenosis. [healio.com]

4 Left ventricular hypertrophy secondary to aortic stenosis, as well as age-related changes, both promote diastolic dysfunction, rendering the geriatric patient with aortic stenosis more dependent on contraction of the atrium for filling the ventricle [uspharmacist.com]
Treatment
Although surgical correction is a more definitive treatment modality, BAV has a long-term durability and is the treatment of choice in patients presenting early. [louisville.edu]
Conversely, even if no symptoms are present, it may be advisable to proceed with treatment or repairs based on the test results. Possible treatments may include valve repair or valve replacement. [heart.org]
Treatments There are essentially three treatment options for aortic stenosis: surgical valve replacement, transcatheter aortic valve replacement (TAVR), or medical therapy. [secondscount.org]
[…] stenosis, valve repair or replacement remains the only definitive treatment. [heart.ucla.edu]
Prognosis
Natural History and Prognosis Valvular AS is frequently a progressive disease, the severity increasing over time. [rjmatthewsmd.com]
There is a favorable long-term outcome following aortic valve surgery and relatively low operative risk. 6 This should be considered in light of the prognosis of congestive heart failure in the very old as worse than the prognosis of most cancers ( 1 [uspharmacist.com]
MSCT may be useful in quantifying the valve area and coronary calcification, which aids in assessing prognosis. [patient.info]
Treatment and prognosis A minority of patients develop aortic regurgitation as a young adult but the majority have progressive valve stenosis, with only about 1% maintaining normal valve function over their lifetime 10. [radiopaedia.org]
Etiology
The University of Michigan is home to the International Registry of Aortic Dissection, and several research laboratories that are exploring the molecular etiologies of aortic diseases. [umcvc.org]

Etiology – Aortic Stenosis The most common cause of aortic stenosis in a person over age 70 years is calcification of a normal trileaflet aortic valve; this process is sometimes referred to as “senile degeneration.” [healio.com]
The TVT registry does not allow for further details of stroke, but it is reasonable to assume an embolic etiology from the calcified valve itself. [acc.org]

Epidemiology of Bicuspid Aortic Valve Disease Bicuspid aortic valve disease is one of the prominent causes of death worldwide and considered one of the most common causes of inherited heart diseases. [lecturio.com]
Epidemiology [ 1 ] AS has become the most frequent type of valvular heart disease in Europe and North America. [patient.info]
Complications stemming from structural heart issues are most often treated through surgical intervention, which could include aortic valve replacement, or balloon valvuloplasty. [16] Epidemiology [ edit ] Bicuspid aortic valves are the most common cardiac [en.wikipedia.org]
However, epidemiological studies, histopathological studies and recent experimental evidence have indicated that calcification of the aortic valve is an active biological process rather than a passive process within the leaflet, thus causing regulated [scielo.br]
