About the department

The cardiovascular surgery department at Memorial Sisli Hospital Istanbul provides comprehensive diagnostics and treatment for patients suffering from cardiovascular diseases. Cardiac surgeons of the department effectively cooperate with colleagues from leading cardiac surgery centres in Europe and the USA. Therefore medical team have the opportunity to be the first in Turkey to introduce innovative surgical techniques into clinical practice. Due to the latest surgical equipment in operating rooms, most heart and blood vessel interventions are performed without thoracotomy and extensive surgical access, contributing to quick recovery after surgery. Furthermore, the department became the first in the country to implant endovascular stents to treat pathological lesions of the large branches of the aorta. The department's surgeons perform more than 1,000 cardiac surgeries of varying severity every year.

The medical team effectively treats patients with congenital heart anomalies, coronary artery occlusion, heart valve problems and heart failure. The department is one of the leading medical institutions where coronary artery bypass grafting is performed using an innovative robotic surgical system. The high professionalism of the department's team of surgeons makes it possible to achieve the most complex cardiac interventions, including the reconstruction of heart valves and coronary vessels.
