Glendale Adventist Medical Center cardiothoracic surgeon Eli R. Capouya, M.D., recently performed a coronary artery bypass grafting (CABG) procedure without needing to clamp the aorta using a new fully automated device to create a secure connection, or anastomosis, between a vein graft and the aorta, the main artery in the human body. The device, the PAS-Port® Proximal Anastomosis System, replaces hand-sewn sutures with an easy-to-use, highly reliable and reproducible automated system.
The current method of connecting a bypass graft vessel to the aorta (known as proximal anastomosis) in CABG surgery often requires that the aorta be clamped and utilizes time-consuming hand-sewn sutures. When the clamp is released, tiny blood clots or particles from the aortic wall can be released, which can then travel to the brain and cause stroke and other neurologic complications.
The PAS-Port system allows a surgeon to complete an automated proximal anastomosis without the need to clamp and manipulate the aorta. Eliminating the clamp may greatly reduce the risk of particle release and ensuing neurocognitive events.
About CABG Surgery
Coronary heart disease causes one out of every five deaths in the United States, making it the single largest killer of Americans. CABG surgery is performed to restore blood flow through the vessels that supply blood to the heart. In the surgery, a small part of a blood vessel is taken from another area of the body, usually a vein from the leg, and surgically attached across an area of severe narrowing or blockage, thus bypassing the problem area. The blood is rerouted through the healthy vessel, and blood flow is restored to the heart muscle. Traditional bypass procedures are performed by stopping the heart and hand sewing the graft vessel around the blockage.
While other treatment alternatives exist, studies show that CABG surgery achieves the best long-term patient outcome for coronary heart disease as measured by survival rate and need for re-intervention. The National Center for Health Statistics estimates that in 2005 approximately 260,000 patients had CABG surgeries in the United States. Each CABG procedure requires approximately five anastomoses, often considered the most critical step of the surgery.
The PAS-Port system, developed by Cardica, Inc., attaches the end of a vein graft to the aorta. With PAS-Port, the bypass graft is loaded into the system and the anastomosis is rapidly completed, typically in just over one minute.
Glendale Adventist Medical Center (GAMC) has been providing quality health care services to residents of Glendale and the surrounding communities for more than 100 years.
