About the clinic
Treatment for atrial septal defect (ASD) at Prof. Öztekin Oto Heart Clinic in Istanbul, Turkey, focuses on minimally invasive surgery. This single-specialty clinic is known for pioneering techniques in congenital heart surgery. Prof. Dr. Öztekin Oto was the first surgeon in Turkey to perform ASD closure through a small 5 cm incision.
The clinic holds a Health Tourism Authorization Certificate and is registered with Health Türkiye. Prof. Dr. Öztekin Oto leads the surgical team with extensive international expertise. He served as the President of the European Society of Cardiovascular Surgery from 2014 to 2016. Prof. Dr. Oto has shared his knowledge in 2,000+ lectures worldwide and holds fellowships with the European Society of Cardiology and the American College of Cardiology.
Advanced diagnostics for heart defects
The medical team uses specific tools to assess the heart's structure and rhythm before surgery. These tests help determine the size of the hole and its effect on blood flow. Patients typically undergo several assessments, including:
- Echocardiography. This ultrasound shows the heart chambers and the location of the defect.
- ECG and Holter ECG. These tests monitor the heart's electrical activity over 24 hours or more.
- Cardiovascular check-up. A full evaluation to prepare the patient for general anesthesia.
Minimally invasive ASD closure
Prof. Dr. Öztekin Oto uses a patented cannula he developed to repair the heart through a small opening. This method is suitable for infants, children, and adults. The technique involves a 5 cm incision rather than a traditional large chest opening. This approach reduces scarring and helps patients recover faster. While surgeons usually use general anesthesia, an awake high thoracic epidural is also an option for some cases.
- Hospital stay. Patients typically stay in the hospital for 3 days.
- Combined procedures. The surgical team can also repair a ventricular septal defect (VSD) or patent ductus arteriosus (PDA) during the same session.
- Equipment. The procedure uses a heart-lung machine and the doctor's patented cannula for precision.
The clinic has specialized in congenital heart surgery since 1996. Because the incisions are small, children and adults often return to their daily activities sooner than with standard surgery. You can request a consultation for heart surgery through the Bookimed platform.

We met our esteemed doctor this weekend for my daughter's check-up. I don't think we could have found anyone more caring and knowledgeable. He was so attentive and cared for my daughter as if she were his own child. He considered every detail and provided information. It's clear he's passionate about his profession. We will continue our follow-ups with him, God willing. May God bless his life. Thank you so much for making us feel safe and secure. With love.
