Cardiac Surgery
DESUN can justifiably claim to have one of the
finest cardiac surgery teams in India. Led by the renowned Doctor, the
member team of senior surgeons and anaesthetists have pioneered several new
surgical techniques over the last few years.
Out of a total number of critical care beds, are devoted to cardio-thoracic
surgery patients. Of the total number of operating theatres, are dedicated
to cardiac care for undertaking surgeries ranging from valve replacements to
correction of congenital defects. Surgical expertise is backed by
sophisticated post-operative care, ensuring that DESUN is one of the best
centers for high-risk cardiac surgeries.
Highly dedicated steel modular operating theatres are fully equipped with
the latest state-of-the-art instruments for the convenience of the surgeons.
The aim is just not to prolong life but to ensure that all normal
activities can be quickly resumed
HEART BYPASS SURGERY (CABS) –
CORONARY ARTERY BYPASS SURGERY, is a surgery by which the surgeon re-routes
or bypasses the blood around blocked arteries by means of a new
artery (taken from the body itself) to improve the blood flow to the heart.
An improved and latest method being done currently is Beating Heart Bypass
Surgery.
Open Heart
Open-heart surgery generally refers to operations
performed on the heart that require a patient being placed on the heart-lung
bypass machine.
The heart-lung bypass machine takes over the function of the heart and
lungs to provide oxygenated blood to the body. The heart can be stopped with
a solution called "cardioplegia" that is a cold, high potassium
solution which also protects the heart muscle while it is stopped. Cold
saline irrigation over the heart is also used to protect the heart while it
is stopped and without its own blood supply.
The heart itself can then be opened and repair can be accomplished in a
bloodless, still environment. In some situations, the heart can be operated
upon while still beating with the patient being supported on the heart-lung
bypass machine.
To get access to the heart, the surgeon has to open the chest. To do so, he
or she has to go through the breast bone (sternum). This is referred to as
the sternotomy. The skin incision is generally smaller in size than the
length of the breast bone, since the skin margins can be stretched to some
extent. For repeat incisions ( a redo-sternotomy) often the length is a
little longer than the previous scar.
For many parents, the concept of a sternotomy raises much concern. However,
sternotomy is one of the safest and more comfortable incisions performed
during surgery. Performing a sternotomy is nothing but an artificial
fracture; at the end of the operation the two edges of the breast bone are
put back together with steel wires. This does not lead to any deformities of
the chest wall, even as a child grows. At the same time, performing a
sternotomy does not prevent the progression of already existing chest wall
deformities (e.g. "pigeon chest").
Pain is sensed by the nerve endings in the affected tissues. In the bone,
pain arises from movement at the site of a fracture. Infants don't have much
chest wall muscle mass to move the sternal edges and develop pain. For that
reason, not surprisingly, most infants are discharged home on just ibuprofen
and Tylenol.
After the chest is opened, a part (or all) of the thymus gland is removed.
The thymus gland is involved in the immune system; however, its removal has
not been shown to lead to any immune compromise. The removal of the thymus
is necessary to allow exposure of the heart, which sits in a thin, leather
like sac called the pericardium. To get access to the heart, this sac has to
be opened, at which time the surgeon can remove a small portion of the
pericardium for later. Often the removed piece is treated with a chemical
called gluteraldehyde to increase the stiffness of the pericardium, making
it easier to manipulate during surgery.
The removed pericardial piece is used during the operation as patch
material for a variety of holes or defects within the heart. The removed
piece of pericardium does not need to be replaced. At times however, a piece
of a synthetic material called Gore-Tex membrane is used to replace the used
pericardium. Typically this is done when the surgeon anticipates a repeat
operation in the future and wishes to protect against injury to the heart
during redo-sternotomy.
