Atrial septal defect Treatment in Prof. Dr. İbrahim Cansaran Tanıdır – Pediatric Cardiology

About the clinic

Atrial septal defect (ASD) treatment at the clinic of Prof. Dr. İbrahim Cansaran Tanıdır in Istanbul, Turkey, focuses on non-surgical closure methods for pediatric patients. Prof. Dr. Tanıdır brings over 20 years of experience to the practice, having performed 2,000+ ASD closures and 10,000+ pediatric cardiac catheterizations. The clinic is known for using low-radiation protocols and fluoroscopy-free techniques to protect children during structural heart procedures.

Advanced diagnostics for heart defects

Accurate imaging is essential to determine the size and location of the hole in the heart wall. The clinic uses several tools to plan the intervention:

  • Echocardiography. This is the primary tool for visualising the defect and guiding device placement.
  • Fetal cardiac MRI. This allows for early detection of heart issues before birth.
  • CT coronary angiography. This provides detailed views of the heart's blood vessels.
  • 3D electroanatomical mapping. This helps assess the heart's electrical activity.
  • Rhythm Holter monitoring. This tracks the heart rate during normal activity and exercise.

Treatment options for atrial septal defect

The choice of treatment depends on the specific type of ASD. While 80% of cases are ostium secundum types suitable for catheter closure, other anatomical variants may require different approaches.

  • Transcatheter ASD closure. This minimally invasive procedure uses a catheter inserted through a vein in the groin. Prof. Dr. Tanıdır deploys a memory-metal device that acts like two small umbrellas to seal the hole. This method avoids chest incisions and requires only 1 night in the hospital.
  • Surgical ASD closure. Open-heart surgery is reserved for complex anatomical types, such as ostium primum or sinus venosus defects. These variants are not suitable for catheter-based devices.
  • Balloon atrial septostomy (Rashkind procedure). This is an emergency intervention for newborns. A balloon catheter creates a temporary opening to improve oxygen levels in "blue baby" conditions.

Recovery and safety standards

Patients undergoing transcatheter closure benefit from rapid recovery with no surgical scarring. Following the procedure, children usually stay in the hospital for 1 night. Prof. Dr. Tanıdır advises avoiding contact sports for 6 months to allow the heart to heal around the device, after which full normal activity can resume. The clinic also provides multilingual support in English, Russian, Arabic, and German to assist international families throughout the treatment process.

Prof. Dr. İbrahim Cansaran Tanıdır – Pediatric Cardiology: more details about the clinic

Turkey, Istanbul

Prof. Dr. İbrahim Cansaran Tanıdır – Pediatric Cardiology is a specialized practice in Istanbul's Ataşehir district. The clinic focuses entirely on pediatric cardiology and interventional pediatric cardiology. It treats congenital heart diseases in children of all ages without surgery.

Key Facts and Academic Achievements

Prof. Dr. İbrahim Cansaran Tanıdır leads the clinic. He has nearly 20 years of clinical and academic experience in pediatric heart care. He has personally performed over 10,000 pediatric cardiac catheterization procedures in Turkey and abroad. His academic work includes 110 SCI/SCIE publications and over 1,440 scientific citations.

The medical team has earned several national awards for clinical excellence. These include the Best Echocardiographic Imaging Presentation award and the Second Best Intervention Presentation award. Both honors came from the National Pediatric Cardiology and Cardiovascular Surgery Congress. The team also won the Best Oral Presentation award for a school-based electrocardiographic screening program.

International humanitarian work shapes much of the clinic's mission. The team has performed over 500 catheterization procedures across several regions:

  • Africa (Mali, Kenya, Uganda, and Libya)
  • Asia (Bangladesh, Kyrgyzstan, and Uzbekistan)
  • Kosovo

This global experience strengthens the clinic's ability to treat diverse and complex structural heart conditions.

Specialties and Interventional Procedures

The clinic specializes in interventional pediatric cardiology. This field uses thin, flexible tubes called catheters to treat heart defects through blood vessels. Because doctors don't open the chest, recovery time drops significantly. The practice treats patients from fetal stages through adolescence.

Congenital Heart Defect Closures

Specialists close holes in the heart using catheter-based methods instead of major surgery. They place special memory-metal devices that resemble small umbrellas or plugs. These devices permanently seal the defects. The clinic reports significant experience in these closures:

  • 2,000+ transcatheter ASD (atrial septal defect) closures
  • 1,000+ PDA (patent ductus arteriosus) closures
  • 250+ VSD (ventricular septal defect) closures

Echocardiography and angiography guide device placement during the procedure. Most children return to normal activities after about six months of healing.

Valve and Vascular Interventions

When heart valves are blocked, the clinic uses balloon valvuloplasty. A deflated balloon travels to the narrowed valve and inflates to widen the opening. This is the primary treatment for pulmonary valve stenosis. The team has performed over 500 balloon valvuloplasty procedures. They also place stents for aortic coarctation and other vascular blockages.

Pediatric Arrhythmia and Electrophysiology

The clinic treats heart rhythm disorders using catheter ablation. A mapping system identifies abnormal electrical pathways in the heart. Controlled heat then eliminates the problem tissue. This procedure often removes the need for lifelong heart medication in children.

Emergency Neonatal Care

For newborns with critical cyanotic (blue baby) conditions, the clinic performs the Rashkind procedure. This balloon atrial septostomy creates a small opening between heart chambers. Oxygen-rich blood can then mix with oxygen-poor blood. Doctors perform this life-saving intervention urgently in the angiography laboratory.

Equipment and Technologies

The clinic uses advanced imaging to ensure accuracy and safety. The team emphasizes low-radiation protocols for pediatric patients. They have completed over 200 fluoroscopy-free or low-radiation catheterization procedures. This minimizes a child's lifetime exposure to medical radiation.

Diagnostic tools available at the practice include:

  • Echocardiography (heart ultrasound)
  • Fetal cardiac MRI and standard heart MRI
  • CT coronary angiography
  • Rhythm Holter monitoring and exercise tests
  • Three-dimensional electroanatomical mapping for arrhythmias

These tools allow precise evaluation of heart murmurs, syncope, and complex structural defects.

Services for International Patients

The clinic offers consultations in Turkish, English, Russian, Arabic, and German. Long-term follow-up is central to its care model. Specialists monitor heart rhythm, valve function, and device compatibility at regular intervals as the child grows.

After our doctor Cansaran carefully assessed the examinations, he explained everything to us one by one. He clearly told us which findings were important, which ones we shouldn’t be worried about, and how the follow-up process would work. When it comes to my dear son-in-law, you can’t help but feel very anxious. Doctor Cansaran gave us confidence with both his knowledge and his calm approach. He answered all of our questions patiently. We’re truly lucky that we were able to reach him.
