About the Department of Cardiac Surgery and Vascular Surgery at Memorial Sisli Hospital Istanbul

The Department of Cardiac Surgery and Vascular Surgery at the Memorial Sisli Hospital Istanbul offers the full range of surgical treatment of cardiovascular diseases, with the exception of heart transplant. The high professionalism of the team of the department's surgeons in combination with advanced equipment allows them to perform the most complex cardiac interventions, including the reconstruction of heart valves and coronary vessels. Due to the presence of state-of-the-art surgical equipment in operating rooms, most interventions on the heart and blood vessels are performed without thoracotomy and extensive surgical access, which contributes to rapid recovery after surgery. The department's specialists most often perform coronary artery bypass grafting, operations to correct heart valve defects and congenital heart defects in adults. The department annually performs more than 1,000 cardiac surgical procedures of varying severity. The Chief Physician of the department is Assoc. Prof. Dr. med. Hasan Ardal.

The department's cardiac surgeons cooperate effectively with colleagues from the leading Heart Surgery Centers in Europe and the United States, and therefore they have the opportunity to be the first in Turkey to introduce innovative surgical techniques into clinical practice. For example, the department's specialists became the first in the country who implanted endovascular stents for the treatment of pathological lesions of the large branches of the aorta. In addition, the department's medical team became the first in Turkey in the use of radiofrequency ablation for the treatment of cardiac arrhythmias.

The department’s key focus is on coronary artery bypass grafting for the restoration of blood flow in the coronary arteries in patients with coronary artery disease. The operation can be both planned and urgent. The intervention is carried out under general anesthesia and it lasts 4-6 hours. Depending on the particular clinical case, the doctor chooses coronary artery bypass grafting with the use of a heart-lung machine, without it, or minimally invasive coronary artery bypass grafting. In addition, the department is one of the first in Turkey where coronary artery bypass grafting is performed using the innovative AESOP robotic surgical system. Another specificity of bypass surgery in the department is the use of an infrared scanner for assessment of the condition of the coronary vessels, the quality of the distal anastomosis and the effectiveness of myocardial revascularization. The heart is accessed through the intercostal space on the left, or via dissecting the sternum. The further task of cardiac surgeons is to create a bypass for blood flow. A part of the radial artery, internal thoracic artery or femoral vein can be used for this purpose. After carrying out the necessary surgical procedures, the thoracic wall is sutured. When the operation is completed, the patient is transferred to the Intensive Care Unit, under 24-hour monitoring. The operation must be followed by rehabilitation, which, in most cases, lasts about a month. The duration and intensity of rehabilitation measures largely depend on the age of the patient and his general state. It should be noted that the mortality rate for coronary artery bypass grafting in the department is below 1% – in medical facilities in developed countries, this figure ranges from 1-3%. The probability of infection during surgery is also practically zero.

Heart valve pathologies are also quite common in the department's clinical practice. Cardiac surgeons specialize in mitral, aortic and tricuspid valve replacement. Valve replacement is performed using mechanical and biological prostheses. The main advantage of mechanical valves is their durability, but after the implantation of such prostheses, the patient has to constantly take anticoagulants. The biological prosthesis is made from animal tissue. When installing it, the patient does not require lifelong intake of anticoagulants (the therapy lasts about six months). However, biological valves wear out quickly – their maximum service life does not exceed 20 years. Thus, the age of the patient also plays an important role in the type of heart valve prosthesis.

In the field of vascular surgery, carotid stenosis treatment is of particular importance. The main modern treatment methods for this pathology are stent implantation (the implantation of a stent, which keeps the vessel in a normal state and does not allow it to narrow), carotid endarterectomy and various techniques for replacement of the vessel section using fragments of the patient's own arteries. The choice of a treatment method is based on the results of comprehensive diagnostics, taking into account concomitant diseases, possible contraindications and other factors.

In addition, the specialists in vascular surgery provide effective treatment of varicose veins. If possible, the preference is given to sparing methods – compression therapy, sclerotherapy, laser procedures, etc. However, classic open surgery is required in some clinical cases. Surgical treatment of varicose veins involves stripping or phlebectomy.
