What causes an arterial blockage?

Before knowing about the various causes of arterial blockage it is very important to understand what arterial blockage actually means. Well, the name clearly suggests that the disease is associated with the arteries and signifies some kind of obstruction. Arterial blockage, commonly known as Atherosclerosis in the medical world is a condition marked by the accumulation of fibrous and fatty substances inside the artery which hinder the normal flow of blood leading to coronary heart diseases. If left untreated, it can increase your chances of suffering a heart attack. The problem can be treated with the help of heart bypass surgery or coronary artery bypass graft (CABG). There are a lot of hospitals where you can easily opt for heart bypass surgery in Delhi. 

The clogging of the arteries, as per the best heart specialist in Delhi, is extremely dangerous and can be caused by various different factors, the most important of these being plaque formation. Plaque is the main culprit behind various heart-related diseases including aortic stenosis. Patients suffering from this are subjected to a treatment known as TAVI heart valve replacement surgery, which is carried out by implanting a new graft besides the damaged valve or replacing the old valve completely. Aortic valve implantation in Delhi is one of the most commonly performed cardiological procedures after heart bypass surgery. 

A person experiencing arterial blockage experiences pain in the lower limbs accompanied by the weakening of the pulse in the legs. In such a scenario you are bound to experience leg cramps commonly known as intermittent claudication. Chest pain is a very common symptom and its intensity may vary depending upon the activity level of the patient.  

• Obesity is one of the major causes of arterial blockage and recent studies have shown that obese people are more prone to heart attack and other cardiovascular problems. Obesity leads to increased levels of cholesterol in the body which accumulates on the walls of the arteries in the form of plaque.
• Increased intake of salt can also lead to arterial blockage.
• The arterial blockage may also be triggered by an existing medical condition like diabetes and hypertension.
• The problem can also be triggered by old age.
• Excessive consumption of junk food, fast food and oily food is also a major cause of arterial blockage.
• The arterial blockage may also be a result of an injury sustained in an accident that critically damages the arteries.
• Smoking and consumption of alcohol can also damage your arteries leading to arterial blockage.
• Stagnant lifestyle also contributes to the problem as excessive stress can damage your arteries thereby increasing your vulnerability to coronary artery disease.
• A stagnant lifestyle which has become quite prevalent nowadays also greatly contributes to the problem.
• High levels of triglycerides in your blood can also lead to arterial blockage.
• Apart from the factors mentioned above, the arterial blockage may also be caused by various other factors that include sleep apnea which is marked by irregular breathing while we are sleeping. This leads to a sudden change in the blood oxygen levels which in turn leads to a rise in the blood pressure, thereby causing severe damage to the arteries.
• During pregnancy, the expecting mother can develop a condition known as preeclampsia which is marked by increased levels of protein in the urine. This can also increase the risks of developing an arterial blockage.

If you have a family history of heart attack, stroke or any other heart problem, it is important to visit a doctor frequently and get yourself checked for any sort of abnormality. Simple changes in your lifestyle and diet can help you to evade the problem.

TAVR: What are the risks involved?

TAVR Valve Replacement in Delhi is one of the most trusted methods for treating damaged aortic valve. Aortic valve is one of the most important part of the human heart. The human heart functions 24 hours a day and sends oxygenated blood to different organs of the body. Also, the deoxygenated blood from various organs is sent back to the heart for purification. The aortic valve is it narrow hollow tube-like structure that acts as a pathway for the free flow of blood and even helps to store the blood before it is sent to the various organs of the human body. The aortic valve also prevents the backward flow of blood. However, the valve might get blocked due to the excess accumulation of impurities like calcium and cholesterol on the interior lining of the valve. Apart from these the valve might also lose its elasticity and become tight. Such condition is commonly known as aortic stenosis in the medical world. Aortic stenosis can prove to be very fatal as it prevents the free flow of blood from the heart to different body parts. This in turn leads to decreasing in the level of oxygen in the body and cause serious health problems, and even death.

Although TAVR Valve Replacement Surgery is one of the most common type of valve replacement surgeries and has a considerably high success rate but it is not necessarily always a success. People suffering from obesity, high blood pressure, diabetes and high cholesterol levels are more vulnerable to develop aortic stenosis. Especially in the case of diabetes patients, the problem becomes very chronic and life-threatening. This is because in the case of sugar patients there is an excessive accumulation of calcium on the walls of the valve. Sugar also leads to inflammation of the valve.

Reports and studies conducted by one of the well-known hospitals for TAVR Valve Replacement Surgery is very risky in case of people having high blood sugar levels. The surgery does not completely eradicate the problem and it's me reoccur after some time. In case of diabetes patients, the success rate is very minimal as compared to normal patients.

Apart from these problems the patient might also suffer from valve leaks. This usually happens when the artificial valve used to replace the damaged valve does not fit perfectly and is smaller in size as compared to the former valve. This leads to the leakage of blood. However, researches are going on to eradicate this problem with the use of technologically advanced equipment.

The surgery can lead a very bad impact on your heart by exerting excessive pressure on the hearts electrical system and you might need to use a pacemaker to restore the normal functioning of your heart. The chemicals used for contrasting may have an adverse affect on your kidneys, however, in most cases, the problem is easily curable. Sometime the blood vessels through which the sheath and catheter is passed might get severely damaged and need to be treated. There have also been cases  where the patient has experienced a stroke during the surgery or a few days after it.

What are the complication one can face after TAVI Surgery?

Heart is one of the most important organs of the human body which performs the job of pumping blood to different organs of the body. Our heart functions 24 hours a day without any break and helps in the oxygenation of the deoxygenated blood coming from different organs of the body which is the sent back to the different organs body via the arteries. Human heart is four chambered and between these Chambers passes a valve. The valve in a very important part of a heart as it prevents the backward flow of blood. Sometimes the valve can get damaged and lead to severe problems in the heart by disrupting the flow of blood. Report shown by a tavi cardiac surgery hospital in Delhi show that most of the patients admitted for transaortic valve implantation in Delhi are majorly elderly people. Apart old age there might be some other factors responsible for damaging the valve such as calcium deposits inside the valve, rheumatic fever, endocarditis etc.

One of the best surgeons for transaortic valve implantation in Delhi enlisted the following symptoms for heart valve diseases:

Unstable Heartbeat accompanied with palpitations.

Difficulty while breathing shortness of breath.

Excessive weakness and fatigue.

Swelling and stiffness in certain body parts like ankles and feet.

Transaortic valve implantation is less invasive as compared to other heart surgeries.

There are certain tests and procedures that you need to undergo before opting for transaortic valve implantation to make sure you are an eligible candidate. Once these are done and the doctor gives you the green signal, you'll be given the date for getting admitted into the hospital. Before the procedure you will be given anaesthesia to induce unconsciousness. In case of transaortic valve implantation surgery, the damaged valve doesn't need to be removed. Instead a new prosthetic valve is inserted with the help of a hollow catheter and balloon.

Although the surgery has proved to be quiet beneficial in many cases but it also has its setbacks. Surgeons in the best tavi cardiac surgery hospital in Delhi are quite aware of the fact that the surgery might not always prove out to be a success and hence inform the patients about all the risks and benefits.

During the surgery the patient is vulnerable to develop endocarditis.  It is a condition in which the inner walls of the heart become infected. Although it is a rare condition but it is very much possible for the patients to develop such infections. Other complications that may rise during a transaortic valve implantation are access (including injury at the arterial access site, arterial tree trauma, and problems with vascular closure), valve deployment (including improper positioning, coronary compromise and annular rupture), valve function (including paravalvular leak), organ injury (including stroke, myocardial ischemia/injury, and acute kidney injury), and arrhythmic complications (including high degree heart block and atrial fibrillation) and late complications including aortic regurgitation and prosthetic valve thrombosis.

Even after the surgery you are at risk of developing infections which can prove very fatal as the heart is very sensitive organ and such infections may affect the success rate of the surgery drastically.

The best possible way to avoid such problems is to lead a healthy lifestyle. Riding on healthy food like fats and keeping a check on your cholesterol levels also helps to keep your heart healthy. You can also try yoga and other exercises as these help to increase blood circulation. Elderly people should try to go out for morning or evening walk as it helps to keep them healthy makes their heart strong.
