AORTIC VALVE STENOSIS SYMPTOMS AND ITS TREATMENT

 

Aortic stenosis can be described as an abnormal narrowing of the aortic valve. There are a variety of causes for inflammation that leads to the aortic valve that is narrowed.

Heart problems can arise when the narrowing is significant enough to block blood circulation from the left ventricle to the arteries.

What happens to the heart when the aortic valve is stenosis?

·         The heart is a muscle pump with four chambers and four valves for the soul.

·         The chambers in the upper part, known as the left atrium and right atrium (atria plural form of atrium), are walled with thin walls. Filling chambers.

·         The blood flows from the left and right atria through the tricuspid and mitral valves, flowing into the chambers below (right ventricles and left).

·         The left and right ventricles are lined with muscular walls to pump blood across the pulmonic and Aortic valves to the circulation.

·         Heart valves are tiny tissue leaflets that open then close right timing during every heartbeat cycle.

·         The principal function of valves in the heart is to stop blood flow in the opposite direction.

·         The arteries carry blood to supply oxygen and other nutrition to the body and then returns as carbon dioxide waste through blood vessels to the right atrium. When the ventricles relax, blood circulation in the right atrium flows via the tricuspid valve and into the right ventricle.

·         As the ventricles contract, blood from the right ventricle gets transported by the pulmonic valve to the lungs to replenish oxygen and remove carbon dioxide.

·         The oxygenated blood returns to the left atrium, where it goes by the mitral valve to the ventricle left.

·         Blood is circulated through the left ventricle over the aortic valve and into the aorta and the blood vessels of the body.

It is believed that the flow of blood into the body's blood vessels can be restricted when aortic narrowing occurs. This can ultimately result in heart failure. Aortic stenosis is three times more often among males than females.

What are the signs and symptoms of aortic stasis?

The most prominent symptoms of aortic stenosis include:

·         Chest pain in the chest (angina),

·         Fainting (syncope) and

·         Shortness of breath (due to an inability to breathe due to a heart problem).

·         In a tiny proportion of patients suffering from aortic stenosis, the initial sign of death is sudden, which occurs most often during intense exercise.

The exact cause of sudden death is unclear. However, it could be due to irregular heartbeats due to the insufficient flow of blood through the aortic valve that is narrowed to the coronary arteries in the heart. The lack of oxygen reaching the lining of the heart muscle results due to the absence of blood flow to coronary arteries, especially when exercising vigorously. The lack of oxygen to the heart muscle can cause chest pain and could cause irregular heart rhythms.

It is the primary symptom in one-third of patients and is eventually seen in one-half of patients suffering from aortic stenosis. The chest pain in patients suffering from Aortic Stenosis is the same as the chest discomfort (angina) sustained by patients who suffer from coronary artery diseases. In both cases, it is noted as pain on the breast bone that is caused due to exertion and eased by rest. For patients suffering from heart disease or coronary artery disease, chest discomfort can be caused by a lack of blood flow to the heart muscle because of coronary arteries that have narrowed. However, for patients suffering from aortic stenosis, chest pain can be experienced with no underlying restriction of coronary arteries. Instead, the heart muscle is thickened and required to pump at high pressure to force blood flow into the narrowed Aortic valve.

A twitching (syncope) due to aortic stenosis can be associated with excitement or exertion. These conditions trigger the relaxation of blood vessels (vasodilation), which decreases blood pressure. Aortic stenosis is a condition where the heart cannot boost output to counter the decrease of blood pressure. This means that blood flow to the brain decreases and causes fainting. The cause of fainting is if cardiac output falls because of an irregular heartbeat (arrhythmia). Without treatment, the life expectancy of an average patient is lower than 3 years following the onset of symptoms of syncope or chest pain.

Shortness of breath due to heart failure is the most ominous warning sign. It results from the heart's inability to deal with the high pressure of Aortic Stenosis. The shortness of breath can be caused due to increased pressure within the blood vessels in the lung due to the increase in force needed to fill the left ventricle. At first, breath shortness is experienced only in the course of activity. However, as the disease progresses, shortness of breath is experienced even during the day's rest. Patients may have difficulty lying down without becoming breathless (orthopnea). If not treated, the typical life expectancy following the first sign of heart failure caused by Aortic Stenosis is between 6 and 24 months.

What is the cause of aortic stenosis?

In adults, three diseases are believed to cause Aortic stasis.

Wear and tear progressive of the bicuspid valve, present from the moment of birth (congenital).

Wear and tear of the Aortic valve during ageing.

The aortic valve is damaged caused by rheumatic fever in an infant or an adult.

Bicuspid aortic valves are the most frequent reason for aortic stenosis in patients younger than 65 years old. Aortic valves typically comprise three leaflets, referred to as cusps. Around 2% of patients have aortic valves with just 2 points (bicuspid valves). The giandliverconsultants provide the best ercp surgery in USA. Though bicuspid valves typically don't hinder blood flow when people are younger, they don't open as much as valves with three cusps. This means that blood flow through the bicuspid valves can be more turbulent, leading to more strain and wear on valve leaflets. In time, wear and tear causes scarring, calcification, and decreased mobility of valve leaflets. Around 10 per cent of the bicuspid valves become substantially narrowed, which causes the heart-related symptoms of aortic stenosis.

The most frequent reason for aortic stenosis among patients aged 65 and above is known as "senile calcific aortic stenosis." As you age, the collagen protein of the valve leaflets gets removed, and calcium gets deposited on leaflets. As a result, the velocity of the valve grows, leading to scarring, thickening and the valve swells after the valve leaflet's mobility has been diminished by calcium calcification. How this process is able and causes significant narrowing in certain patients but not in other patients is unknown. The progressive condition that causes the aortic calcification and the stenosis does not have anything to do with good lifestyle choices, in contrast to the calcium that may accumulate within the coronary artery to cause heart attacks.

Rheumatic fever is a disease that is caused by untreated infections caused by streptococcal group Bacteria. Damage to valve leaflets due to Rheumatic fever can cause increased turbulent flow across the valve and further damage. The rheumatic fever-related narrowing results from the melting (melting between) on edge (commissures) in the leaflets. Rheumatic aortic narrowing usually happens with a certain degree of regurgitation of the aortic artery. In normal circumstances, the valve in the aortic chamber closes to stop blood from the aorta from returning to the left ventricle. In the case of aortic regurgitation, the valve is damaged and allows blood flow back into the left ventricle because these muscles loosen the following pumping. The patients also have a degree of rheumatic injury to the valve that connects to the mitral. The condition is reasonably rare throughout the United States, except in immigrants from developing cuntries.
