The commissures--openings between the valve leaflets--are manually separated by the surgeon.
D. Commissurotomy
Resection with commissurotomy is a surgical procedure commonly used to treat infundibular stenosis, a condition where there is narrowing of the infundibulum (outflow tract) of the heart. During the procedure, the surgeon removes the obstructive tissue causing the stenosis and may also separate any fused valve leaflets to improve blood flow. This helps to relieve the obstruction and improve overall heart function.
Zaidel's study on commissurotomy patients found that split-brain patients displayed differences in processing visual information across the two hemispheres. Specifically, the left hemisphere tended to specialize in language-related tasks, while the right hemisphere showed strengths in spatial abilities and emotion recognition. This research provided insights into the functional specialization of the two hemispheres of the brain.
Aortoplasty is a general term for surgical repair of the aorta. That depends on the type of repair that is being performed, it can be called "Endovascular aortic aneurysm repair" when it is a surgical procedure to repair an aortic aneurysm done through the major blood vessels of the body. Depending on the procedure used and the problem being repaired different techniques may be used such as: Patching, used when there are tears in the valve, fixed through surgical insertion of a tissue patch. Commissurotomy, which is when the valve is narrowed, an incision of a commissure into the valve is used to fix the problem. Reshaping, used to reshape the valve so that it can close properly. Valvuloplasty, used to increase opening of valve and improve blood flow when the valve has become rigid with calcium buildup. This is done through the insertion of a balloon catheter. Decalcification, used when there is a calcium build up, removes excess calcium so that valve can function properly.
