Type of pediatric surgery can benefit older persons: study
March 13 (HeartCenterOnline) - A study finds that a type of heart valve replacement surgery, typically performed in children, shows benefit in individuals aged 50 years and older. The results are published in the March 2003 issue of the Annals of Thoracic Surgery.
This type of heart valve replacement surgery, known as the Ross procedure, replaces an aortic valve that is severely narrowed (stenosis) and/or improperly closing, allowing blood to leak back in the wrong direction (regurgitation). The aortic valve plays a critical role in the nourishment of organs, cells and tissues. Oxygen-rich blood is normally pumped from the heart, through the aortic valve and out the aorta to the rest of the body. If the aortic valve is defective, then the rest of the body could be damaged from a lack of oxygen.
The Ross procedure, which is an open-heart surgery, replaces the aortic valve with the patient's healthy pulmonic valve, which is best suited for the purpose. Now the patient needs a replacement for the pulmonic valve. This valve allows oxygen-poor blood to travel from the heart, through the pulmonic valve and into the pulmonary artery, which is connected to the lungs. Therefore, during the same surgery, the pulmonic valve is replaced with a healthy valve from a deceased human donor. The main advantage of the Ross procedure is that the new aortic valve will grow with the patient, which is very important for children.
The Ross procedure has enjoyed significant results in affected children, with an overall success rate of over 90 percent. This can translate to a prolonged and improved quality of life. In the current study, the researchers sought to answer whether other age groups can benefit from the procedure, and which age group can profit most.
From February 1995 to August 2001, the research team performed 250 Ross procedures. Forty-six patients were age 2 to 25 years; 123 patients ranged from age 26 to 49; 81 patients were ages 50 to 67. Valve function was assessed using echocardiography at two through six months postoperatively, and then yearly.
The study demonstrated "excellent results in all age groups," but with particularly superior results in the treatment of aortic valve disease in middle age and older patients.
