Thanks to a world-renowned team of cardiac physicians who specialize in
unique procedures, techniques, and heart conditions, Torrance Memorial
strives to stop the heart disease epidemic. Heart disease claims the lives
of 600,000 men and women annually, while The
Centers for Disease Control and Prevention (CDC) recently calculated that more than 720,000 Americans have a heart attack
each year. Of these annual attacks, 515,000 are a first heart attack and
205,000 are repeat attacks.
Torrance Memorial is pleased to have Jack Sun, MD, on staff. With a post-graduate
Transcatheter Cardiovascular fellowship from Harvard, extensive experience
at University of Washington Medical Center and his support of Torrance
Memorial’s new affiliation with USC Keck School of Medicine, the
South Bay now has the best and most varied of cardiac surgery resources.

You specialize in all aspects of adult cardiac surgery, but can you tell
us what your specific research interests are?
Thank you. I am thrilled to be here! I have both clinical and research
interests. I do perform all aspects of heart surgery to treat valvular,
aortic and coronary disease but also for atrial fibrillation as well.
My greatest interests currently include mitral valve repair and transcatheter
aortic valve replacement (TAVR). Repairing a patient’s mitral valve
allows them to keep their own valve without needing an artificial one.
TAVR is allowing us to replace the aortic valve for severe aortic stenosis
without traditional open heart surgery and is a great option for patients
who are either very high risk or too high risk for open surgery.
My research interests have mostly involved looking at antithrombotic therapies
in cardiac surgery. I have been involved in multiple studies looking at
antithrombotic drug effects in coronary bypass surgery, and I was a member
of the panel and writing committee for the American College of Chest Physicians
Guidelines for Antithrombotic Therapy for Valvular Heart Disease.
Is there anything you’d like the public to know about aortic disease/dissection,
like advances in technology to treat aortic disease?
Aortic dissection can be a quick killer. The public needs to know the signs:
chest or back pain that is often tearing in nature. Get to the ED as soon
as possible to be assessed. For some types of thoracic aortic dissection
and aortic aneurysm, repair can now be performed using catheter-based
devices that allow stents to be placed inside the aorta to exclude the
aneurysm or dissection. This can be done through an artery in the groin
rather than through a large, open operation—a technique called Thoracic
EndoVascular Aortic Repair (TEVAR).
