Procedures
Bentall Procedure

A Bentall procedure is a surgery conducted to correct problems associated with the largest artery in the body, the aorta. The aorta carries oxygenated blood from the heart to the rest of the body. Thus, any problem with this important artery may affect the rest of the body and cause serious complications.

A Bentall operation is conducted to correct problems associated with the aorta. Some of the problems that are resolved with the help of a Bentall surgery include the following:

  • Marfan’s syndrome: It is a congenital disorder characterized by weakening of the aortic wall
  • Aortic aneurysm: It is characterized by the widening of the aortic valve
  • Aortic dissection: It refers to the tearing of the inner layer of the aorta
  • Aortic regurgitation: It is a condition in which the aortic valve is not able to close properly
CABG - Redo

In the United States Coronary artery bypass graft which is a common kind of an open heart surgery if found to be executed in good numbers. Cardiothoracic surgeons are the doctors who are involved in performing the procedure on the concerned patients. This kind of procedure is very appropriate for coronary heart diseases which can become a life-threatening issue later.

About CABG - Redo

Awaxy substance called plaque hets deposited in good amount in the coronary arteries of the heart, they supply oxygen to the heart. With time the plaque starts hardening and eventually ruptures and breaks open. This plaque interferes with blood flow as arteries grow narrow at that region. A blood clot develops when the plaque ruptures open on the surface.  The artery gets blocked if the blood clot developed is very large. This can be the cause of heart attack in a later stage becoming the cause of a life risk.

Symptoms of CABG - Redo

When the heart gets deprived of rich oxygenated blood there is chest pain and discomfort felt by the patient. This pain is referred to as angina. Breathlessness and fatigue are some of the other kinds of problems that are associated with coronary heart disease. In worse case scenario a heart attack which can be life-threatening may affect the patient severely

About CABG - Redo

Coronary artery bypass surgery aims at improving the general blood circulation to the heart. A healthy artery or vein is taken the body and is grafted or connected to the blocked coronary artery for the purpose of bypassing. This artery or vein goes around the blocked portion of the coronary artery and establishes a new path for the blood to flow to the heart thus reducing the chance of a heart attack. In one surgery surgeons can bypass multiple coronary arteries. Severe blockages can be treated with this procedure.

Cardiac Valve Replacement

Heart valve diseases occur due to improper functioning of the valves. Sometimes a valve does not open or does not close proper. In this condition, the blood does not flow properly and requires valve replacement. The important valves present in human body are aortic valve, mitral valve, tricuspid valve and pulmonary valve. If a valve cannot be repaired, then a heart valve replacement surgery is performed.

Heart valve replacement surgery is the replacement of heart valves with artificial valves or bioprosthesis. It is an alternative treatment to valve repair.

Valve replacement includes four procedures:

  • Aortic valve replacement (AVR)
  • Mitral valve replacement (MVR)
  • Tricuspid valve replacement (TVR)
  • Pulmonary valve replacement (PVR)

The aortic valve and the mitral valve replacements are the most common. Pulmonary and tricuspid valve replacements are uncommon in adults.

Aortic valve replacement (AVR)

It is a procedure in which a diseased aortic valve is replaced with an artificial heart valve. Many diseases affect the aortic valve; the valve can either become leaky or partially blocked. Recent aortic valve replacement procedures include open-heart surgery via a sternotomy, minimally invasive cardiac surgery (MICS) and transcatheter aortic valve replacement (TAVR).

Coronary Artery Bypass Grafting (CABG)

What is Coronary Artery Bypass Grafting (CABG)

Coronary artery bypass grafting (CABG) is a type of an open heart surgery that intends to improve the flow of blood to the heart. It involves the placement of a coronary artery bypass graft, which is retrieved from a healthy artery in the body, and placed in the position of the blocked portion of the artery that supplies blood to the heart. CABG surgery is a complex, yet common procedure.

A waxy substance called plaque may deposit in good amount in the coronary arteries of the heart over a period of time. As time advances, the plaque starts hardening and eventually ruptures and breaks open. The plaque interferes with blood flow as arteries grow narrow at the affected region. A blood clot develops when the plaque ruptures. The artery may get blocked completely is the size of the clot is big enough to stop the flow of blood to the heart. This may eventually lead to serious events such as heart attack and also put the individual at the risk of death.

The person may experience chest pain and discomfort when the heart is deprived of rich oxygenated blood This pain is referred to as angina. Breathlessness and  fatigue are some of the other problems associated with coronary heart disease.

How does CABG improve the heart condition

Coronary artery bypass surgery aims at improving the overall blood circulation to the heart. A part of healthy artery or vein from another part of the body is taken and is grafted or connected to the blocked coronary artery for bypass. This artery or vein goes around the blocked portion of the coronary artery and establishes a new path for the blood to flow to the heart, thus reducing the chance of a heart attack. In a single surgery, surgeons can bypass multiple coronary arteries. Severe blockages can be treated with this procedure.

CABG is conducted when there are one or two blockages in the artery. High risk CABG is conducted when there are multiple blockages in the artery and the blood flow to the heart is severely restricted.

Heart Double Valve Replacement

There are four types of valves in the human heart – the mitral, aortic, tricuspid, and pulmonary valve. The mitral and the tricuspid valve are present between the upper and the lower chambers of the heart. On the other hand, the aortic and the pulmonary valve are present in the two arteries that leave the heart.

Most often, it is the mitral and the aortic valve that undergoes certain pathologic changes due to degenerative valve diseases, rheumatic heart diseases, or infective endocarditis. This may result in problems associated with the valve opening and closure.

These dysfunctions can be treated with either valve repair or valve replacement surgery. Aortic valve replacement or mitral valve replacement is carried out when just one of the valve is diseased or damaged. However, when both the valves are diseased or damaged, a double valve replacement surgery is conducted.


About the ailment

The heart valves present in the heart are responsible for permitting the flow of nutrient-laden blood through the heart chambers. After allowing the ushering of blood, each valve is expected to close completely. The diseased or damaged valves are not able to open and close properly, thus allowing the mixing and backflow of blood (regurgitation).

 A double valve replacement surgery mainly aims at correcting the problem of valvular heart disease and involves both aortic valve replacement and mitral valve replacement. The mitral valve is situated between the left atrium and the left ventricle while the aortic valve is located in between the aorta and the left ventricle.

Causes of Heart Valve Disease

Some of the causes of heart valve disease include the following:

  • Cardiac stenosis or narrowing
  • High blood pressure and heart failure, which enlarges the heart and arteries and contribute to valvular diseases
  • Atherosclerosis
  • Scar tissue formation and damage due to heart attack or any injury to the heart
  • Strep throat or rheumatic fever can give rises to valve problems
  • Infection due to germs entering bloodstream can affect heart valves and one such infection is infective endocarditis
  • Lupus-like autoimmune diseases can affect the aorta and mitral valve
  • Carcinoid syndrome
  • Diet medicines such as fenfluramine and phentermine can at times give rise to valve diseases
  • Marfan syndrome
  • Metabolic disorders such as Fabry disease or high blood cholesterol
  • Radiation therapy to the chest can give rise to heart valve diseases.

Symptoms of Double Valve Replacement

Some of the symptoms of valvular heart disease include the following:

  • Fluid retention in the lower limbs
  • Chest pain
  • Fatigue and light-headedness
  • Dizziness and shortness in breath
  • Cyanosis

About heart valve replacement

Double valve replacement surgery is a complicated procedure as compared to single valve replacement surgery. Aortic valve replacement and mitral valve replacement involves the replacement of just one valve but during double valve replacement surgery, both the diseased valves are removed at the same time and replaced with a synthetic (mechanical) or a biological valve.

In the case of mechanical valves, the components used are not of organic or natural origin. They are created from a combination of polyester and carbon material that the human body can tolerate and accept. Blood-thinning medications are given to patients who get mechanical valves to prevent blood clot formation.

Bioprosthetic valves or the biologic valves are either created from animal or human tissues and can be of the following types:

  • A bovine valve is usually derived from the tissues of a cow and is connected to the heart with the help of silicone rubber
  • A porcine valve has its origin rooted from a pig tissue and is implanted in the heart with or without the frame like a stent
  • A homograft or an allograft is usually collected from the human donor’s heart

The choice of a particular type of valve depends on the age, overall fitness, and the ability to metabolize anticoagulant medications. The only problem associated with a bioprosthetic valve is that it may not last a lifetime and one may have to undergo a replacement again later.

VSD Closure / Repair (Adult)

Holes in the heart are considered to be congenital heart diseases or defects. These are considered to be a problem in the structure formation of the heart right at the time when a foetus is deriving its nutrition in the womb. With latest procedural technologies these problems can be mended right after birth. The holes in the heart disrupt the normal blood through the heart thus causing a general problem in blood circulation in the entire body.

About VSD Closure / Repair (Adult)

In order to understand the holes in heart we must briefly understand the working of the heart. The heart works like a pump beating on an average of 100,000 times in a day. It has two sides which is divided by a wall called septum. The right side of the valve pumps blood to the lungs and picks up oxygen. The oxygen rich blood then returns to the left side of the heart from the lungs and then the left side pumps it to the rest of the body.

These two sides are divided into 4 chambers having four valves connecting them to various blood vessels. For carrying blood from the body to the heart, veins are responsible while arteries carry the blood away from the heart to be circulated to the body. The atria are two upper chambers that collect blood while ventricles are the two lower chambers pumping the blood to the lungs and other parts of the body.

The valves act like doors allowing flow of blood through the next chamber to arteries and then they close to keep the blood from again returning back to the previous chamber from where it came. In a systolic contraction ventricle pump blood from the heart and in a diastolic contraction the ventricles relax to receive blood pumped by the atria while aortic and pulmonary valves close at the beginning of the diastole to prevent the chances of backflow.
