We provide professional support in Cardiology.
As a science, the department of cardiology deals with all diseases and disease risks concerning the heart and circulatory systems.
Heart disease symptoms such as pain felt in the chest area, shortness of breath, numbness in the left part of the body are evaluated initially in the cardiology department. However, the symptoms of heart diseases are not limited to them.
At the Group Florence Nightingale Hospitals Cardiology Center, our cardiologists successfully treat the heart diseases and vascular diseases using current treatment methods.
When there is a suspicion of cardiovascular diseases, one or more of the following tests are applied to the patient and the treatment process is started.
After applying the tests mentioned above, the patient’s heart disease or the risk of heart disease is identified and, based on the disease status, the patient’s treatment is started or, if necessary, the patient is directed to the department of cardiac surgery for surgical procedure.
Patients that complain about cardiac disorders or begin to experience symptoms of cardiovascular diseases make an appointment to receive treatment. However, the duration of treatment can be prolonged since cardiology and cardiac surgery departments are often confused. In order to eliminate this confusion and to not prolong the treatment process, it is necessary to be able to distinguish the characteristics of cardiology department from cardiac surgery department.
Although the areas of interest in cardiac surgery and cardiology departments are quite similar, they are separate branches of medicine since the treatment methods offered to the patient are different.
As the symptoms of heart disorders begin to appear, the patient should be examined in the cardiology department first.
If this examination indicates a disease that is unlikely to be treated or controlled by drugs, the patient is directed to the cardiac surgery department for surgical treatment. The patient’s situation and the health risk he carries continue to be monitored by cardiologists even after the patient is directed to the department of cardiac surgery. While getting acquainted with this whole process, it is necessary to know the diseases that the department of cardiology deals with and manages.
First, some tests are applied to the patients who present to the cardiology department with the complaints such as shortness of breath, compression in the chest area, pain and numbness in the left part of the body and the jaw, sweating, and nausea caused by these ailments. The diagnosis of coronary artery disease, arrhythmia, heart failure or heart valve disease is made after one or more of the Exercise Test, Holter ECG, ECHO (Echocardiography), CT Coronary Angiography, Myocardial Perfusion Scintigraphy and Cardiac Catheterization are performed.
Unlike cardiac surgery that performs surgical treatment, cardiology department is able to treat the cardiac diseases also with medical methods not requiring surgery such as non-surgical aortic valve replacement (TAVI) and pacemaker (pacemaker).
Department of cardiology deals also with hypertension, acute coronary syndrome, ischemic heart diseases, aortic stenosis and insufficiency, cardiac arrhythmias, acute myocarditis, mitral valve stenosis and insufficiency, primary and cardiac tumors, angina pectoris, tricuspid stenosis and similar diseases.
Group Florence Nightingale Hospitals Cardiology Center provides services with its 30-year experience, strong medical team of expert and experienced cardiologists, and advanced equipment.
In our Cardiology Center, many cardiologic diseases from hypertension to metabolic syndrome and from coronary artery diseases to heart rhythm disorders are successfully treated.
Our experienced specialist physicians who closely follow the latest developments in their field successfully implement the analyses, diagnosis and treatment of cardiovascular diseases in the field of electrophysiology, echocardiography, cardiac catheterization, coronary angiography, coronary balloon/stent procedures as well as in the other fields of interventional cardiology.
Echocardiography uses sound waves (ultrasound) to produce images of inner structure and functions of the heart.
Vessels that supply heart’s muscle tissue are called “coronary vessels”. Atherosclerosis is formation of plagues (produced by fatty accumulation and calcification) in the blood vessel wall.
Nuclear Cardiology testing investigates the blood flow to the heart and heart’s function and produces no difficulty to the patient. All tests in Nuclear Cardiology should be completed within few hours during the day and do not require hospitalization.
A healthy heart contracts approximately 70 to 80 times per minute and 100.000 times a day. So, it pumps around 300 liters of blood to the whole body per hour.
Interventional cardiology is a branch of cardiology that deals specifically with the catheter based treatment of structural heart diseases. Procedures are performed by specifically trained cardiologist. Since there is no surgery performed, the leading doctors are not cardiovascular surgeons, but cardiologists.

Commonly performed procedures of our Heart Center team:
• Cardiac Catheterization and Angiography
Vessels that supply hear’s muscle tissue are called “coronary vessels”. Atherosclerosis is formation of plagues (produced by fatty accumulation and calcification) in the blood vessel wall. These plagues may result in obstruction or stenosis of the vessels. Stenosis or obstruction of coronary arteries might cause chest pain and heart attack (myocardial infarction) in the patient.
The basic principle to prevent stenosis of coronary arteries is to improve risk factors.
Measures are the essential for treatment, e.g. regular checks of diabetes mellitus, loss of weight, treatment of hypertension, improvement of high cholesterol and triglyceride values, cessation of smoking, and regular exercises.
• Coronary Angiography and Cardiac Catheterization
Despite preventive measures taken, if complaints are present suggesting stenosis of coronary arteries, or if any abnormalities are detected by pre-tests (e.g. effort test, thallium test, etc.), cardiac catheterization and coronary angiography are performed to identify location and size of this stenosis. In case the stenosis is critical, the treatment options can be balloon angioplasty-stent or bypass operation. Both of these treatment options are performed safely in our day.
Cardiac catheterization is a diagnostic method that has been used for people since 1930s, and has been widely utilized since 1953. At the present time femoral artery is often used while arm vessels are rarely used. Cardiac catheterization and coronary angiography are diagnostic methods not treatment. It is based on imaging of cardiac cavities and coronary arteries with injection of contrast material and also measuring the pressure of the cardiac cavities and associated vessels.
The patient is delivered a tranquilizer and transferred to catheter laboratory after signing informed consent form. Femoral or arm section is anaesthetized to place a cannula in the vessel. The thin catheter made of plastic-like material is guided through cardiac cavities first to record the pressure then contrast material is injected for taking pictures. Then coronary arteries are displayed and recorded. This procedure takes approximately 15 -30 minutes.
• Percutaneous Mitral Balloon Valvuloplasty
Mitral valve is located between the left atrium and the left ventricle. It has two leaflets. Mitral stenosis occurs when two leaflets of the valve thicken and attach to each other, and is characterized by narrowed valve as a result of thickened and shrunk muscles and fibers holding the mitral valve. Mitral stenosis is a heart valve disease developed associated with acute rheumatic fever suffered in the childhood.
Mitral stenosis prevents oxygenated blood coming from the lungs from passing from the left atrium to the left ventricle. Therefore, the left atrium is the first to enlarge then the blood begins accumulating in the lungs. Intrapulmonic pressure is increased by accumulated blood in the lungs, and the patients will have complaints of shortness of breath, cough, heart-throb, and in the advanced stages hemoptysis (pulmonary edema or pulmonary congestion) may occur.
Treatment of mitral stenosis varies depending on the severity of stenosis. Pharmacotherapy should be enough for mild stenosis. Diuretics will be helpful to prevent accumulation in the lungs and beta blockers will be useful for heart-throb. With progressed stenosis, percutaneous mitral balloon valvuloplasty (PMBV) or open heart surgery (surgical repair or replacement of mitral valve) is performed.
Mitral balloon valvuloplasty is used to enlarge narrowed mitral valve by a balloon. When performed on appropriate patients, mitral balloon valvuloplasty has many advantages over open heart surgery.
The most important advantage is that the patient does not receive general anesthesia, and the rib cage is not opened. Thus, the patient is conscious during the procedure and does not require intensive care after the procedure.
In addition, patients are able to recover in short time and mostly discharged the following day.
Another important advantage is that a large number of patients, who has received a mitral balloon valvuloplasty, does not need to use anticoagulant drugs if no arrhythmia occurs while the patients, who have undergone an open heart surgery and implanted an artificial (prosthesis) valve, need to use anticoagulant drugs (coumadin-warfarin) for a lifetime.
Mitral balloon valvuloplasty procedure is performed by interventional cardiologists at angiography laboratory.
• Inguinal region is cleaned with an antiseptic solution to apply a local anesthetic prior to procedure.
• A cannule is placed in the inguinal artery and vein and guided to the heart’s right atrium by a catheter then the wall between the heart’s right and left atria is perforated by a specific needle to get to the left atrium.
• The balloon catheter is guided from the left atrium to left ventricle by a specific wire then inflated at the mitral valve to enlarge the valve as much as possible.
• The wire and balloon catheter is removed after the procedure and a bandage is applied on the inguinal region.
• The patient is advised a bed rest and discharged the following day if no problem occurs during follow-up.
• The success rate of mitral balloon valvuloplasty is higher than 90%.
• Most patients will have a well-being for about 20 years.
• Mitral balloon valvuloplasty procedure may be repeated, if necessary, when mitral valve becomes narrowed again.
Mitral balloon valvuloplasty procedure has been performed for years at our hospital. We are the leading hospital with a serious of 1200 cases in the world and in the country. We perform mitral balloon valvuloplasty safely.
• Transcatheter aortic valve implantation (TAVI) has been developed for elderly patients with aortic stenosis associated with wear, and patients in high-risk group because of coexisting diseases and for who an open heart surgery is considered risky, and started to use widely in the world after 2005.
• The valve used in line with the developed technology, and the application of implant system become easier each year.
• It is currently applied on over 10.000 patients across the world.
• There are two valves mostly used through catheter, Sapien XT (Edwards) and Corevalve (Medtronic). This valves are similar to bioprosthesis valves which are surgically implanted.
• TAVI procedure is performed at catheter laboratory by team work of invasive cardiology, cardiovascular surgery, echocardiogram, and anesthesia staff.
• Inguinal region is mostly accessed when the patient is under anesthesia. The heart is reached through aorta and calcified aortic valve is enlarged by a balloon then biological tissue prosthesis valve is implanted.
• The entire procedure is monitored by echocardiogram through esophagus so that precise measurements can be provided.
Based on more than 30-years’ experience in each field of cardiology and cardiological interventions, Group Florence Nightingale Hospitals, Heart Center team easily and effectively tackle cardiac problems from different levels of severity.
A Cardiac Pacemaker is an electronic device implanted in the body to correct heart’s rhythm and transmission system disorders.
It is vital to correct transmission system disorders, especially bradycardia. A device called pacemaker is implanted in the body to correct bradycardia and for better performance of daily activities. A pacemaker is an electronic device with two parts.
Pulse Generator: the part producing stimulus
Lead or Electrode: The part transmitting
Pulse generator consists of a battery and electronic circuit. Battery is usually lithium. Electronic circuit is a miniature computer with various programs installed in. The programs can be changed when required by a magnet. The power from the battery is converted to small electronic pulses and transmitted to the heart by lead. The electronic circuit controls the timing and intensity of electric stimuli transmitted to the heart.
Lead (electrode) provides the transmission between the heart and the pulse generator. It is usually an insulated wire from polyurethane.
A pacemaker has two important functions:
• Stimulation:Producing a stimulus at a required rate when the heart doesn’t produce one or when it is slow,
• Detection or Sensation: Detecting and monitoring the heart’s natural activity; producing a stimulus when required. So, a pulse generator will not produce a stimulus when the heart has its rhythm.
There are two types of a cardiac pacemaker.
• Temporary Cardiac Pacemaker: In some cases, temporary blocks or bradycardia may occur in the heart. Such cases will naturally recover. However, a temporary cardiac pacemaker is implanted to maintain patient rhythm and life until it get backs to normal.
It consists of a pacemaker box and special lead. The lead is placed inside the heart through a vascular access (from neck, arm or groin). The other end of the wire is connected to the pacemaker box. Such pacemakers implanted temporarily are easy to remove when the patient recovers.
• Permanent Pacemaker:Implanted in the body permanently.
There are two methods of implantation:
• Endocardial method:The electrode is guided through a blood vessel to be placed in the heart. The procedure required local anesthesia.
• Epicardial method:The electrode is directly stitched on the heart muscle. This procedure requires general anesthesia. It is rare in cases where it is impossible to perform endocardial method.
Endocardial Implantation of Permanent Pacemaker
This procedure is performed in a special catheter lab with a radioscopy device and under full sterilization, administering local anesthesia. During the procedure, the surgeon and assisting staff will wear a sterile dress, bonnet, and mask as in the operating theatre. The front side of the chest is cleaned with a special solution and covered with a sterile blanket. The pacemaker is usually implanted in the left chest (may be in the right side) below the clavicula.
The site is incised in 8-10 cm. Depending on the type of the pacemaker implanted 1-2-3 leads are guided through the vessels exposed by incision to be placed in the required cavity of the heart. Measurements we call threshold measuring are performed to see the state of the lead to detect and produce a stimulus. The leads are then attached to tissues and vessel at the site of incision. The other end of the lead is connected to the pulse generator which is placed in the pocket specially prepared under the skin, and the skin is sutured.
Depending on the condition of the heart, the heart chamber to be stimulated must be determined before.
• One-chamber stimulation: The right atrium and the right ventricle are selected for this stimulation. Only one lead is used.
• Two-chamber stimulation: Both the right atrium and the right ventricle of the heart are stimulated. Two leads are placed in the right atrium and right ventricle.
• Three-chamber Bi-Ventricular stimulation: A special type of stimulation used in heart failure. Three leads are placed in the right atrium, right ventricle, and coronary sinus. In this case, the right atrium, right ventricle and left ventricle will be stimulated.
The procedure usually takes 1-2 hours for implantation of a permanent pacemaker. In implantation of three-chamber pacemakers, it may take time to find the coronary sinus and implant the lead, resulting in prolonged time for the procedure around 3-4 hours.

Medical tourism has come to prominence in Turkey recently, with a year-on-year increase in the number of foreign patients to choose medical packages that offer a combination of treatment, holiday and transportation. High treatment costs and long waiting lists in some foreign countries have impelled people to look for countries where they can receive high-quality treatment, as well as a visit for a vacation.
Main reasons for selecting Turkey for treatment include:
Group Florence Nightingale has been at the forefront of the healthcare industry in the region since 1989. Group Florence Nightingale has developed “Centers of Excellence” with expert treatment, surgery and diagnostic capabilities across the Group’s four hospitals and two medical centers, each center gaining recognition in its specialization not only in Turkey but throughout the region.
