The Center boasts 12 active operating rooms and one hybrid operating room, all of which are outfitted with cutting-edge equipment not only for adult open and closed heart surgeries such as coronary artery bypass grafting and valvular repair but also for pediatric open and closed heart surgeries such as the occlusion of patent ductus arteriosus, atrial septal defect, ventricular septal defect, and patent foramen ovale as well as cardiac valve replacement and congenital heart disease treatment. Annually, a total of 4500 to 5000 surgical operations are performed in the Center’s ORs, which is unique even by international standards. All the surgical operations are performed by a team comprising subspecialist surgeons, subspecialist anesthetists, and qualified clinical perfusionists.
