The effect of statins on the progression of AS is unclear. The latest trials do not show any benefit in slowing AS progression, but did demonstrate a decrease in ischemic cardiovascular events.

In general, medical therapy has relatively poor efficacy in treating aortic stenosis. However, it may be useful to manage commonly coexisting conditions that correlate with aortic stenosis:

- Any angina is generally treated with beta-blockers and/or calcium blockers. Nitrates are contraindicated due to their potential to cause profound hypotension in aortic stenosis.

- Any hypertension is treated aggressively, but caution must be taken in administering beta-blockers.

- Any heart failure is generally treated with digoxin and diuretics, and, if not contraindicated, cautious administration of ACE inhibitors.

While observational studies demonstrated an association between lowered cholesterol with statins and decreased progression, a randomized clinical trial published in 2005 failed to find any effect on calcific aortic stenosis. A 2007 study did demonstrate a slowing of aortic stenosis with the statin rosuvastatin.

Treatment is generally not necessary in people without symptoms. In moderate cases, echocardiography is performed every 1–2 years to monitor the progression, possibly complemented with a cardiac stress test. In severe cases, echocardiography is performed every 3–6 months. In both moderate and mild cases, the person should immediately make a revisit or be admitted for inpatient care if any new related symptoms appear. There are no therapeutic options currently available to treat people with aortic valve stenosis; however, studies have indicated that the disease occurs as a result of active cellular processes, suggesting that targeting these processes may lead to viable therapeutic approaches.

For newborns with transposition, prostaglandins can be given to keep the ductus arteriosus open which allows mixing of the otherwise isolated pulmonary and systemic circuits. Thus oxygenated blood that recirculates back to the lungs can mix with blood that circulates throughout the body. The arterial switch operation is the definitive treatment for dextro- transposition. Rarely the arterial switch is not feasible due to particular coronary artery anatomy and an atrial switch operation is preferred.

In the first stage of restenosis, administering anti-platelet drugs (called IIb/IIIa inhibitors) immediately after surgery greatly reduces the chance of a thrombosis occurring.

Drug-eluting stents are now being trialled in Europe, Canada and the USA, as well as in Asia-Pacific. These stents are coated with pharmaceuticals that inhibit tissue growth and thus reduce the risk of restenosis from scar-tissue and cell proliferation.

There has been some success with these new stents in reducing the occurrence of restenosis, with clinical studies showing an incidence rate of 5% or lower.

In adults and children found to have coarctation, treatment is conservative if asymptomatic, but may require surgical resection of the narrow segment if there is arterial hypertension. The first operations to treat coarctation were carried out by Clarence Crafoord in Sweden in 1944. In some cases angioplasty can be performed to dilate the narrowed artery, with or without the placement of a stent graft.

For fetuses at high risk for developing coarctation, a novel experimental treatment approach is being investigated, wherein the mother inhales 45% oxygen three times a day (3 x 3–4 hours) beyond 34 weeks of gestation. The oxygen is transferred via the placenta to the fetus and results in dilatation of the fetal lung vessels. As a consequence, the flow of blood through the fetal circulatory system increases, including that through the underdeveloped arch. In suitable fetuses, marked increases in aortic arch dimensions have been observed over treatment periods of about two to three weeks.

The long term outcome is very good. Some patients may, however, develop narrowing (stenosis) or dilatation at the previous coarctation site. All patients with unrepaired or repaired aortic coarctation require follow up in specialized Congenital Heart Disease centers.

If restenosis occurs without a stent, it is usually treated with more angioplasty. Once restenosis has occurred and been treated by angioplasty, the chances of restenosis occurring again are increased by a factor of 2. This treatment is also used if restenosis occurs at either the proximal or distal end of the stent.

If restenosis occurs within a stent (also known as in-stent stenosis), it may be treated with repeated angioplasty and insertion of another stent inside the original, sometimes with a drug-eluting stent.

Over the past 5 years, ISR is preferentially treated with a drug eluting balloon, which is a balloon coated with the same anticancer drugs that prevent restenosis. The Balloon avoids the need for a double layer of metal which is used when an in-stent restenosis is treated with another stent within the original stent

Alternative treatments include brachytherapy, or intracoronary radiation. The radiation kills cells and inhibits tissue growth (similar to a patient undergoing cancer therapy).

Surgical treatment involves resection of the stenosed segment and re-anastomsis. Two complications specific to this surgery are Left recurrent nerve palsy and chylothorax, as the recurrent laryngeal nerve and thoracic duct are in the vicinity. Chylothorax is a troublesome complication and is usually managed conservatively by adjusting the diet to eliminate long chain fatty acids and supplementing medium chain triglycerides. When conservative management fails surgical intervention is required. Fluorescein dye can aid in the localisation of chyle leak.

Treatment is varied depending upon the nature of the case. In severe cases, coronary artery bypass surgery is performed to redirect blood flow around the affected area. Drug-eluting stents and thrombolytic drug therapy are less invasive options for less severe cases.

Many approaches have been promoted as methods to reduce or reverse atheroma progression:

- eating a diet of raw fruits, vegetables, nuts, beans, berries, and grains;

- consuming foods containing omega-3 fatty acids such as fish, fish-derived supplements, as well as flax seed oil, borage oil, and other non-animal-based oils;

- abdominal fat reduction;

- aerobic exercise;

- inhibitors of cholesterol synthesis (known as statins);

- low normal blood glucose levels (glycosylated hemoglobin, also called HbA1c);

- micronutrient (vitamins, potassium, and magnesium) consumption;

- maintaining normal, or healthy, blood pressure levels;

- aspirin supplement

- cyclodextrin can solubilize cholesterol, removing it from plaques

Put simply, take steps to live a healthy, sustainable lifestyle.

Subclavian steal syndrome (SSS), also called subclavian steal phenomenon or subclavian steal steno-occlusive disease, is a constellation of signs and symptoms that arise from retrograde (reversed) blood flow in the vertebral artery or the internal thoracic artery, due to a proximal stenosis (narrowing) and/or occlusion of the subclavian artery. The arm may be supplied by blood flowing in a retrograde direction down the vertebral artery at the expense of the vertebrobasilar circulation. This is called the "subclavian steal". It is more severe than typical vertebrobasilar insufficiency.

The AAOCA is a rare birth defect in the heart that occurs when a coronary artery arises from the wrong location on the main blood vessel, the aorta.

Children and young adults with these defects can die suddenly, especially during or just after exercise. In fact, AAOCA is the second leading cause of sudden cardiac death in children and adolescents in the United States behind hypertrophic cardiomyopathy. The prevalence is estimated at 0.1% to 0.3% of the general population. Neither the true risk of sudden death nor the best way to treat these patients is known with certainty. Because of the risk of sudden death, doctors face the pressure to “do something” but in the absence of long-term follow-up data, the risks and benefits of different management options are unconfirmed. This study will create a pool of information that may guide future choice of treatment options for these children and young adults.

This study will be ongoing for 15 years. It is expected that approximately 1000 patients will be enrolled.

This funding to start the registry was provided by The Children's Heart Foundation, The Cardiac Center at The Children's Hospital of Philadelphia and from CHSS member institutions.

Preexisting diabetes mellitus of a pregnant mother is a risk factor that has been described for the fetus having TGV.

Anomalous origin of the right coronary artery originating from the pulmonary trunk (ARCAPA) is a rare but potentially fatal anomaly. The goal of surgical therapy is establishment of a physiologic bi-coronary circulation.

Since 1981 Lecompte has put his Lecompte manoeuvre in use. This is used with the REV (Réparation à l'Etage Ventriculaire). This surgery is like the Rastelli procedure, but with the use of the pulmonary artery without a conduit.

It was Bex who introduced in 1980 the possibility of aortic translocation. But Nikaidoh has put the procedure in practice in 1984. It results in an anatomical normal heart, even better than with an ASO, because also the cones are switched instead of only the arteries as with an ASO.

It has as contra-indication coronary anomalies.

The treatment of coronary artery ectasia is normally done in conjunction with therapies of other heart disorders such as atherosclerosis and hypertension. To prevent the formation of blood clots and the blockage of the vessels, patients are commonly placed on anticoagulant therapy (e.g. warfarin, and aspirin), as well as anti-spasm therapy of calcium channel blockers. Coronary artery ectasia also responds to statins and ACE inhibitors.

A stenosis is an abnormal narrowing in a blood vessel or other tubular organ or structure. It is also sometimes called a stricture (as in urethral stricture).

Stricture as a term is usually used when narrowing is caused by contraction of smooth muscle (e.g., achalasia, prinzmetal angina); stenosis is usually used when narrowing is caused by lesion that reduces the space of lumen (e.g., atherosclerosis). The term coarctation is another synonym, but is commonly used only in the context of aortic coarctation.

Restenosis is the recurrence of stenosis after a procedure. The term is from Ancient Greek στενός, "narrow".

The epidemiology of pulmonary valve stenosis can be summed up by the congenital aspect which is the majority of cases, in broad terms PVS is rare in the general population.

Coronary artery anomalies (or malformation of coronary vessels) are congenital abnormalities in the coronary anatomy of the heart. By definition, these abnormalities are variants of anatomy occurring in less than 1% of the general population. They are often found in combination with other congenital heart defects. Many coronary anomalies don't cause symptoms and are recognized only at the time of autopsy.

They can be associated with sudden death. The real risk of death or the best way to treat these patients is not yet known. The Congenital Heart Surgeons' Society has started a long-term ongoing study called anomalous aortic origin of a coronary artery (AAOCA) to identify the best way to treat this defect.

Bicuspid aortic valves are the most common cardiac valvular anomaly, occurring in 1–2% of the general population. It is twice as common in males as in females.

Bicuspid aortic valve is a heritable condition, with a demonstrated association with mutations in the NOTCH1 gene. Its heritability (formula_1) is as high as 89%. Both familial clustering and isolated valve defects have been documented. The incidence of bicuspid aortic valve can be as high as 10% in families affected with the valve problem..Recent studies suggest that BAV is an autosomal dominant condition with incomplete penetrance. Other congenital heart defects are associated with bicuspid aortic valve at various frequencies, including coarctation of the aorta.

Newer clinical trial results (2007), e.g. the COURAGE trial, have demonstrated that aggressively treating some of the physiologic behavioral factors that promote atheromas with "optimal medical therapy" (not opening narrowing(s), a.k.a. stenoses, per se) produced the most effective results in terms of improving human survival and quality of life for those identified as having already developed advanced cardiovascular disease with many vulnerable plaques.

In terms of treatment for pulmonary valve stenosis, valve replacement or surgical repair (depending upon whether the stenosis is in the valve or vessel) may be indicated. If the valve stenosis is of congenital origin, balloon valvuloplasty is another option, depending on the case.

Valves made from animal or human tissue (are used for valve replacement), in adults metal valves can be used.

A study showed that those who quit smoking reduced their risk of being hospitalized over the next two years.

Smoking increases blood pressure, as well as increases the risk of high cholesterol. Quitting can lower blood pressure, and triglyceride levels.

Secondhand smoke is also bad for the heart health.

Classically, SSS is a consequence of a redundancy in the circulation of the brain and the flow of blood.

SSS results when the short low resistance path (along the subclavian artery) becomes a high resistance path (due to narrowing) and blood flows around the narrowing via the arteries that supply the brain (left and right vertebral artery, left and right internal carotid artery). The blood flow from the brain to the upper limb in SSS is considered to be "" as it is blood flow the brain must do without. This is because of collateral vessels.

As in vertebral-subclavian steal, coronary-subclavian steal may occur in patients who have received a coronary artery bypass graft using the internal thoracic artery (ITA), also known as internal mammary artery. As a result of this procedure, the distal end of the ITA is diverted to one of the coronary arteries (typically the LAD), facilitating blood supply to the heart. In the setting of increased resistance in the proximal subclavian artery, blood may flow backward away from the heart along the ITA, causing myocardial ischemia due to coronary steal. Vertebral-subclavian and coronary-subclavian steal can occur concurrently in patients with an ITA CABG.

Coronary ischemia can be treated but not cured.

By changing lifestyle, further blockages can be prevented. A change in lifestyle, mixed with prescribed medication, can improve health.
