Cardiothoracic and Vascular Surgeons are the first in Texas to implant a
Sorin Perceval STM Self-anchoring Aortic Heart Valve as part
of a brand new clinical trial. Dr. John Oswalt and Dr. Faraz Kerendi,
cardiothoracic surgeons with Cardiothoracic and Vascular Surgeons,
performed the procedure on two patients at Heart Hospital of Austin.
Cardiothoracic and Vascular Surgeons is one of 25 sites around the
country taking part in the study. The Perceval S valve has already been
approved for use in Europe, and over 58 patients have already received
the valve in the United States. The surgical procedures performed by
Cardiothoracic and Vascular Surgeons and other sites during this trial
will be used to help pave the way for FDA clearance of the Perceval S
valve in the U.S.
"We are delighted to begin the process of bringing this cutting-edge
technology to patients in the U.S.," said Dr. William Kessler,
cardiothoracic surgeon with Cardiothoracic and Vascular Surgeons and
principle investigator for the study in Austin. "Because it is a
sutureless valve, it could be particularly ideal for medium to high-risk
patients with aortic stenosis. We can implant the valve using a
minimally invasive approach, so the valve replacement is potentially
less traumatic for the patient and could result in a faster recovry."
It is estimated that 1.5 million Americans are suffering from aortic
stenosis, and conditions in which the aortic valve-the main valve that
controls blood flowing out of the heart-doesn't fully open. This is
generally caused by a build-up of calcium. Over time, the heart
compensates by having the surrounding heart muscles thicken in order to
push more blood out of a smaller opening. This can lead to chest pain,
as well as blood backing up in the lungs. In the most severe cases, not
enough blood makes it back into the brain and the rest of the body.
The Perceval S valve is designed to replace both native aortic valves
and other aortic prosthetic devices. The valve is made from a bovine
pericardium sewn to a super elastic alloy frame. This allows the
Perceval S valve to self-adjust to each individual's heart without a
surgeon attaching it to the wall of the heart with sutures. It is
designed to enable the surgeon to use minimally invasive techniques when
implanting the Perceval S valve, which has the potential to
significantly cut down on time in the operating room. Minimally invasive
surgery has been shown to reduce patient time under anaesthesia and

About Cardiothoracic and Vascular Surgeons
For over five decades, Cardiothoracic and Vascular Surgeons (CTVS) has
been proud to offer Central Texas the most specialized and innovative
cardiothoracic, vascular, and pediatric surgical care available. The
most sophisticated diagnostic and surgical techniques are provided by 24
CTVS surgeons from offices in Central Austin, Williamson County, Hays
County, and all area hospitals. Individually and collectively, CTVS
surgeons have amassed a record of medical "firsts" in Central Texas,
including performing the first heart and kidney transplants in the area.
Since 1958, the surgeons along with the clinical team of physician
assistants, nurses, and technicians, have shared a commitment to
patients, their health and the community. To learn more about
