Abbott Announces Launch of Catheter-Based MitraClip(R) System in Australia for Mitral Regurgitation, the Most Common Heart Valve Condition

First-of-its-Kind, Minimally Invasive Treatment Option for Select Patients

ABBOTT PARK, Illinois, March 30, 2011 - Abbott (NYSE: ABT) today announced the launch of the company's
catheter-based MitraClip(R) system for the treatment of mitral regurgitation
(MR) in Australia. The MitraClip device, which has received Therapeutic Goods
Administration (TGA) approval, offers a new treatment option for patients
suffering from MR, a debilitating heart valve condition.

Chronic, severe MR is often associated with heart failure and can result
in death if left untreated. The MitraClip system represents an important
therapeutic option for patients with this debilitating disease, many of whom
may have no other treatment options.

The first patients were successfully treated in Australia by a
multidisciplinary team including interventional cardiologist Eric Yamen,
M.D.; cardiothoracic surgeon Jurgen Passage, M.D.; and echocardiologist
Christopher Finn, M.D.; all at Sir Charles Gairdner Hospital in Perth.

"The availability of the MitraClip system provides physicians with a
safe, minimally invasive treatment for mitral regurgitation that may provide
new hope for many people for whom surgery is not an option," said Dr. Yamen.
"This therapy has the potential to improve the quality of life for many sick
patients, enabling them to have a more active lifestyle."

The MitraClip system includes a catheter-based device that is delivered
to the heart through the femoral vein, a blood vessel in the leg. The
MitraClip therapy is designed to reduce significant MR by clipping together
the leaflets of the mitral valve, one of the four valves of the heart.
Significant MR is a debilitating condition in which the heart's ability to
function continues to deteriorate over time, and may lead to irregular
heartbeats, heart failure, stroke, heart attack or death. The condition
traditionally has been managed with medications, which can relieve symptoms
but do not address the underlying cause of the condition, or open-heart
surgery. Many people who suffer from MR are not treated surgically(1) because
they are not referred to surgery, are not sick enough, or are too frail for
an invasive procedure.

"The MitraClip system is a breakthrough therapy that serves as a great
example of Abbott's commitment to bringing innovative cardiac and vascular
therapies to patients worldwide," said Robert Hance, senior vice president,
vascular, Abbott. "Nearly 3,000 patients around the world have benefited from
MitraClip treatment, and we are pleased that it is now commercially available
in Australia."

New Clinical Study to Gather Additional Clinical and Health-Economic Data

Abbott today also announced the initiation of a new clinical study of the
MitraClip device that will enroll up to 150 patients at up to 15 sites in
Australia and New Zealand. The primary objective of the single-arm,
prospective trial is to gather real-world clinical and health-economic
outcome data to evaluate the long-term safety, efficacy and economic value of
the MitraClip system. Patients in the study will be evaluated at discharge
and after 30 days and six, 12 and 24 months following the procedure.

Patients will be selected for inclusion in the study by a
multidisciplinary team involving specialists in interventional cardiology,
cardiac surgery and echocardiology.

David Muller, M.D., director of the Cardiac Catheterization Laboratories
at St. Vincent's Hospital in Sydney, Australia, and Jurgen Passage, M.D.,
cardiothoracic surgeon at Sir Charles Gairdner Hospital in Perth, Australia,
will serve as the principal investigators of the study.

About Mitral Regurgitation (MR)

MR is the most common type of heart valve insufficiency,(2) occurring
when the leaflets of the mitral valve do not close completely, causing blood
to flow backwards and leak into the left atrium of the heart during the
cardiac cycle. To maintain an adequate forward flow of blood throughout the
body, the heart compensates by increasing the size of the left ventricle (the
main pumping chamber of the heart) to accommodate the increase in the volume
of blood it is pumping. The chronic volume overload caused by MR requires the
heart to work harder and may ultimately lead to heart failure and other
complications. MR traditionally has been managed with drugs or open-heart
surgery, depending on an individual patient's severity of MR and risk
factors.

About the MitraClip Technology and Procedure

Abbott's proprietary MitraClip system is designed to reduce significant
MR by clipping together the leaflets of the mitral valve, one of the four
valves of the heart. The catheter-based MitraClip device is delivered to the
heart through the femoral vein, a blood vessel in the leg. The heart beats
normally during the procedure, and therefore does not require a heart-lung
bypass machine. After treatment, patients are usually home within two to
three days and have been observed to recover quickly. The safety and efficacy
of the MitraClip system was evaluated in EVEREST II, the first randomized
clinical trial to compare a catheter-based mitral valve device to mitral
valve surgery.

The MitraClip system received CE Mark in March 2008 and is commercially
available in Europe, Turkey, Israel and Australia. The first-in-man clinical
trial of the MitraClip system was conducted in the United States, where it is
an investigational device currently under review for approval by the U.S.
Food and Drug Administration.
