Prof. Dr. İstemihan Tengiz

Areas of Expertise

Every stage of cardiovascular health, from hypertension management to advanced interventional procedures.

01

Core Expertise: Hypertension

Hypertension has been at the centre of Prof. Tengiz's career. He is among the leading figures in hypertension awareness and treatment in Turkey.

Hypertension

Diagnosis, medical treatment and interventional approaches for resistant cases.

Resistant Hypertension

Assessment of high blood pressure that does not respond adequately to medication.

Renal Denervation (RDN)

Catheter-based ablation of sympathetic nerves around the renal arteries.

Ambulatory Blood Pressure Monitoring

24-hour recording of blood pressure and evaluation of its circadian rhythm.

Hypertension Excellence Centre

Holistic hypertension management with a multidisciplinary team.

Target Organ Damage Follow-up

Protecting the heart, kidneys, eyes and brain from hypertension.

Interventional Cardiology

Catheter-based imaging and treatment of the coronary arteries.

Coronary Angiography

Imaging of narrowing and blockages in the coronary arteries.

Angioplasty and Stenting

Opening blocked arteries with balloon and stent (PCI).

TAVI

Transcatheter aortic valve implantation — valve replacement without open surgery.

CTO

Chronic total occlusion — crossing completely blocked arteries.

Balloon Valvuloplasty

Widening narrowed heart valves with a balloon.

EVAR

Endovascular repair of abdominal aortic aneurysm.

Structural and Valvular Disease

Treatment of aortic, mitral, tricuspid and pulmonary valve disease.

Aortic Valve Disease

Treatment planning via TAVI or referral for surgery.

Mitral Valve Disease

Balloon valvuloplasty and assessment with advanced imaging.

Tricuspid and Pulmonary Valve

Balloon valvuloplasty procedures.

Carotid Artery Stenosis

Reducing stroke risk with carotid stenting.

Heart Failure and Arrhythmia

Device therapies and advanced management of heart failure.

Permanent Pacemaker

Implantation for the treatment of slow heart rhythm (bradycardia).

ICD Implantation

Defibrillator against the risk of sudden cardiac death.

Cardiac Resynchronisation (CRT)

Restoring pumping coordination in heart failure.

Atrial Fibrillation Management

Rhythm/rate control and anticoagulation planning.

Preventive Cardiology

Measuring and reducing risk before disease develops.

Cardiovascular Risk Assessment

Ten-year risk calculation using SCORE and Framingham.

Cholesterol Management

Individualised LDL targets and treatment follow-up.

Lifestyle Counselling

Nutrition, exercise, salt restriction and smoking cessation.

Hypertension Training for Family Physicians

Community-based awareness and education programmes.

Palpitations

Heartbeat awareness, arrhythmia differentiation and treatment approaches.

Palpitation Evaluation

Detailed history, ECG, and rhythm analysis with Holter when indicated.

24-Hour Holter Monitoring

Continuous cardiac rhythm recording during daily activities.

Echocardiography

Structural and functional assessment of the heart.

Atrial Fibrillation Management

Rhythm control, rate control and anticoagulation therapy.

Supraventricular Tachycardia

Diagnosis and treatment of sudden rapid heartbeats.

Cardiology Tests

ECG, echocardiography, Holter, stress test and advanced imaging methods.

ECG (Electrocardiography)

Recording of the heart's electrical activity; rhythm and ischemia assessment.

Echocardiography

Ultrasound imaging of the heart; valve structure and pump function.

24-Hour Holter ECG

Continuous cardiac rhythm recording during daily activities.

Stress Test (TREADMILL)

Evaluation of the heart's response to exertion on a treadmill.

Ambulatory Blood Pressure Monitor

Periodic blood pressure measurement over 24 hours.

Cardiology Check-up

Early screening of heart and vascular health, risk assessment.
