The Ozaki technique is an innovative alternative technique for aortic valve replacement using tissue from the sac around your heart (autologous pericardium).
The aortic valve separates your heart's lower left chamber from your aorta. If the valve isn't working as it should, it can disrupt blood flow to your heart and through your body.
The goal of the Ozaki aortic valve replacement is to replace the nonworking valve with a new one using your own tissue.
People with aortic valve disease who haven't had prior open-heart surgery are potential candidates for the Ozaki aortic valve replacement procedure.
To request an appointment, contact the UPMC Heart and Vascular Institute:
The Ozaki aortic valve replacement procedure has shown long-term benefits with few reported risks, compared to mechanical and animal tissue valve replacements.
People who have this surgery heal within 1 to 2 months. And unlike mechanical valve replacements, they typically don't need to take long-term blood thinners afterward.
The valve created from your own heart sac tissue instead of foreign animal tissue is much like a healthy valve.
Risks of the Ozaki aortic valve replacement technique are much like the risks of other aortic valve replacement procedures:
The surgeons at UPMC Heart and Vascular can treat the following aortic valve diseases with the Ozaki aortic valve replacement method:
If the Ozaki aortic valve replacement procedure is a treatment option for you, you'll have pre-op testing.
This includes noninvasive scans, like a CT scan of the chest, to:
The Ozaki aortic valve replacement technique is an invasive surgery. Your care team will give you general anesthesia and put you on a heart-lung machine.
During the 3 to 4 hour procedure, your surgeon:
