Coronary Artery Bypass Surgery (CABG)
Coronary artery bypass surgery detours blood around
blocked coronary arteries, enabling blood to flow to
the heart and other organs. To accomplish this, a segment
of a blood vessel is taken from another part of the
body and is attached (grafted) to the aorta on one end.
On the other end, the segment is grafted onto the coronary
artery, bypassing the blockage.
Bloodless Cardiac Surgery
Using an advanced approach to cardiac surgery, NJCI
minimizes the use of blood and blood products and for
those who request it, NJCI attempts to avoid the use
of transfusions completely. NJCI is one of the few centers
in the region that routinely performs cardiac surgery
often without the use of blood transfusions. Even complex
procedures like coronary artery bypass grafts (CABG)
and heart valve replacements are often done this "bloodless"
way.
Minimally Invasive Surgery
For more than 30 years, coronary artery
bypass graft (CABG) surgery has been saving lives. However,
this procedure comes with certain risks. During this
procedure, the heart is stopped for a number of hours
while the patient is connected to a heart-lung machine
(commonly referred to as the "pump") that
takes over breathing and blood circulation. A surgeon
makes a large incision (approximately 8-10 inches) down
the middle of the chest and separates the breast-bone
to provide clear access to the heart.
Because the heart is stopped for a number of hours
during the CABG procedure, this procedure comes with
certain risks. Possible complications related to this
procedure are bleeding, stroke, renal failure, and neurological
and cognitive problems. The average length of stay in
the hospital is 5 to 7 days and patients have a recovery
time of 4 to 5 weeks. But major medical advances in
the way these surgeries are performed are lowering risks
and offering less invasive alternatives.
NJCI lessens the trauma of this major procedure by
offering two minimally invasive methods of bypass surgery:
Minimally Invasive Direct Coronary Artery Bypass surgery
and Off-Pump Coronary Artery Bypass surgery.
At NJCI, surgeons may use a minimally invasive approach
by making smaller incisions. In some cases, this operation
can be done on the heart while it is still beating.
Patients may have quicker recovery times and fewer complications.
Minimally invasive surgery offers quicker recovery
Like the traditional CABG, minimally invasive surgery
shunts blood around blocked arteries with grafted portions
of other blood vessels. However, in minimally invasive
procedures, a small incision is made between the ribs
giving surgeons access to the heart. In some cases,
a surgeon may choose to do minimally invasive surgery
as an off-pump procedure, without the use of a heart-lung
machine.
MIDCAB
Minimally Invasive Direct Coronary Artery Bypass surgery-
Another alternative, minimally invasive direct
coronary artery bypass surgery, uses a small incision,
made between the ribs, to give the surgeon access to
the heart. In some cases, a surgeon may choose to do
minimally invasive surgery as an off-pump procedure
as well.
While this surgery is highly effective, it is not for
everyone since access for MIDCAB is limited to the front
and left side of the heart. However, quicker recovery
time makes it more attractive. Patients usually spend
3 to 5 days in the hospital and recover within 3 to
4 weeks.
Eligible patients usually have only one or two lesions
in very specific areas, while patients who undergo the
traditional CABG procedure may have up to 7 vessels
bypassed at one time. However, each case is different,
and patients should discuss all the options with their
surgeon regarding what is right for them.
OPCAB
Off-Pump Coronary Artery Bypass surgery - Off-pump
surgery is performed without use of the heart-lung machine.
Using state-of-the-art mechanical devices, surgeons
can isolate the area of the heart in need of repair,
while still allowing the heart to beat normally. This
type of surgery, when appropriate, allows surgeons the
same broad access to vessels that a traditional CABG
procedure provides, with fewer complications. Patients
usually spend 4 to 6 days in the hospital and require
a 4 to 5 week recovery time at home.
At NJCI, consultations with your surgeon to discuss
treatment options are a key component to patient care.
All surgical decisions are determined by a patient's
specific and individual needs.
Radiofrequency Ablation
Radiofrequency ablation is a curative treatment used
for treating many types of arrhythmias. An arrhythmia
is essentially a misfiring of electrical impulses within
the heart. Radiofrequency ablation is usually performed
by threading electrode catheters, guided by fluoroscopy,
into the cavities of the heart and delivering radiofrequency
energy to a precise spot where the troublesome tissue
is located thereby permanently destroying it.

The robotic arm mimics a surgeon's hands but
with greater precision. |
Now, radiofrequency, microwave, and laser ablation
is being used in surgery, but instead of being threaded
via catheter, the surgeon knows the electrical pathways
and isolates the electrical conduction paths that cause
the atrial arrhythmias. Surgical use of radiofrequency,
microwave, and laser ablation is particularly useful
for patients with mitral valve problems when in atrial
fibrillation - a type of arrhythmia that is difficult
to treat with the catheter method.
Robotic Surgery
The da Vinci system, designed by Intuitive Surgical,
allows the surgeon to sit at a computer control console
about 10 feet away from the patient. Technically, the
device is not a robot, because its arms are operated
in real time by the surgeon. The surgeon's fingers are
placed in Velcro rings and connected to master controller.
When the surgeon's fingers move, the robot arms move.
Another arm is used to operate a 3-D camera.
The da Vinci system offers greater precision –
surgeons are able to use tiny holes to access the chest
cavity, instead of large incisions, which leaves smaller
scars and allows for a shorter recovery time.
While it is not yet approved by the FDA for coronary
artery bypass surgery, da Vinci can be used for mitral-valve
replacement surgery and for harvesting of the internal
mammory artery, crucial to many bypass surgeries.
Valve Replacements
Heart Valves help regulate the flow of blood through
the heart. If there is damage to the valves, the heart
may not be able to pump properly. Valve replacement
surgery can be done with either artificial valves or
living tissue valves.
