What is minimal invasive cardiac surgery
(MICAS)?
Minimally invasive heart surgery (also
called keyhole surgery) is a newer form of cardiac surgery. In this type of
heart surgery, small incisions are done, without dividing the central
breastbone or sternum. That means instead of "cutting open the chest"
from midline as they do with traditional open heart surgery, a small and
cosmetic incisions using specialized instruments is used for procedure.
How is the procedure carried out?
MICS procedure is carried out through a
small 5 cm incision on the side of the chest (mini thoracotomy) without
damaging any bones. In females, the incision is under the breast fold making it
even more cosmetic.
Similar to a regular heart surgery, the
operation is performed using
all arteries or a combination of arteries
and veins removed from the leg.
The vessel from the leg in these
operations is also removed endoscopically without cutting the skin over the leg.
Special instruments, camera and cannulas
are used for performing the surgery through this small incision.
Is MICAS CABG a beating heart operation?
Yes, it is an off pump or beating heart
operation. The support of a pump may rarely be required but the operation is
still performed on the beating heart. Pump support may particularly be used
when the heart is weak.
What are the Common Indications of the
MICAS? :
Coronary artery disease - Minimally
invasive coronary artery bypass
Cardiac rhythm disorders- Minimally
invasive atrial fibrillation ablation
Mitral valve disease- Minimally invasive
mitral valve repair placement/repair
Aortic valve disease- Minimally invasive
aortic valve replacement/repair.
Congenital cardiac disease
Removal of cardiac tumours
How does it differ from conventional
cardiac surgery?
No bones are cut like in conventional
heart surgery hence reducing pain, retaining function and having a positive
effect on breathing.
The incision measures just 2-3inches
which makes it impossible to tell that a heart surgery has been performed.
The return to normal life is faster and
patient can perform daily activities like including driving or other activities
without any disruption.
Blood loss is almost negligible and
therefore eliminating blood transfusion and eliminating blood borne infection.
The procedure is ideal in diabetics and
older patients who have poor resistance to infections as all infections are
reduced whether it is wound infections or post-surgical lung infection.
The procedure lasts only 4 days.
What are the contraindications for the
surgery?
Acute myocardial infarction
Severe peripheral vascular disease
(arteries and veins)
Severe left ventricular dysfunction of
the heart
Morbid obesity
What are the benefits of MININMAL INVASIVE
cardiac surgery?
Faster recovery to normal work
Small cosmetic incision
Less painful
Lesser blood loss and reduced amount of
blood transfusions
Lesser chances of infection
Better wound healing
Earlier mobilisation and shorter hospital
stay after surgery in ICU
Better quality of life after surgery
What is the risk of infections after MICAS
CABG?
The risk of infection is close to zero. All
infections are reduced dramatically in MICS CABG even in diabetics. It is due
to the fact that the incision is small and no bone is fractured.
What are the precautions I would have to
take after MICS?
After minimally invasive heart surgery, you
may have an improved quality of life and reduced symptoms.
Incorporate healthy lifestyle changes —
such as physical activity, a healthy diet, stress management and avoiding tobacco
use — into your life.
Your doctor will instruct you about when
you can return to daily activities, such as working, driving and exercise.
Attend regular follow-up appointments with your doctor. You may have several
tests to evaluate and monitor your condition.
Participate in cardiac rehabilitation — a
program of education and exercise designed to help you improve your health and
help you recover after heart surgery.
To keep your heart healthy after surgery,
it is important to make lifestyle changes and take your medications as prescribed.
