She has strong skills in echocardiography, pre‑ and post‑procedure care, long‑term follow‑up, and team‑based cardiac care.
Professor Sung-Ho Kim, MD, MS, PhD, is a pediatric cardiologist and congenital heart disease specialist with more than 40 years of experience. He trained at Hanyang University College of Medicine (MD) and Hanyang University Graduate School (MS, PhD). He helped advance catheter-based treatment of ASD, VSD, tetralogy of Fallot, and other defects. This work reduced the need for open-heart surgery. He has performed more than 1,200 pediatric and congenital cardiac interventions.
He has led academic and clinical programs. He contributes to research and training. He also participates in professional cardiology societies and presents at international conferences.
South Korea provides advanced atrial septal defect (ASD) treatment through catheter-based closure or open-heart surgical repair. Specialized cardiac centers like Sejong Hospital emphasize minimally invasive device closure for secundum-type defects. These procedures involve highly experienced interventional pediatric cardiologists using modern diagnostic echocardiography and digital imaging.
Bookimed Expert Insight: Patient volume is a major quality indicator in South Korea. Sejong Hospital treats over 400,000 patients annually and maintains a massive multidisciplinary staff. Specialized hospitals like this often offer more deep-niche expertise in pediatric cardiology than general clinics. This high volume leads to refined protocols for catheter-based interventions and faster recovery times.
Patient Consensus: Patients often hope for catheter closure because it typically leads to a shorter hospital stay and faster recovery. Many emphasize checking if the defect anatomy is eligible for a device before committing to traditional surgery.
Atrial septal defect (ASD) closure in South Korea is highly successful. Leading centers report success rates between 95.8% and 100%. Surgeons prioritize percutaneous device closure to avoid open-heart surgery. Facilities often hold Joint Commission International (JCI) and KOIHA accreditations for safety.
Bookimed Expert Insight: While many search for surgical options, South Korean specialists focus heavily on catheter-based interventions. Dr. Sungho Kim at Sejong Hospital has performed 1,200 procedures. He pioneered techniques that minimize the need for open-heart surgery. This high procedural volume at specialized centers like Sejong ensures clinicians handle complex defect shapes with high precision.
Patient Consensus: Patients note the procedure feels routine and much less intense than expected. Many describe immediate relief from fatigue and shortness of breath quickly after the device is placed.
Transcatheter closure is often preferable for atrial septal defect (ASD) due to its minimally invasive nature. It avoids large chest incisions or heart-lung bypass machines. South Korean JCI-accredited centers utilize specialized devices to achieve high success rates with faster recovery and fewer complications.
Bookimed Expert Insight: South Korea leads in specialized pediatric cardiac care. Clinical data from Sejong Hospital shows Prof. Dr. Sungho Kim alone has performed 1,200+ procedures. This massive volume ensures precise device anchoring even in complex congenital cases. Patients should prioritize clinics like Severance Hospital that offer both catheter and robotic options to ensure anatomy-based decisions.
Patient Consensus: Patients value the lack of a chest scar and how quickly they can start walking again. Some are surprised a device remains in the heart and note temporary fatigue is normal during the first week.
Follow-up care after ASD closure requires structured monitoring to ensure device stability and proper healing. Patients typically undergo echocardiography within 1–2 weeks and 6 months post-procedure. Standard protocols include antiplatelet therapy for 6 months and antibiotic prophylaxis during dental work to prevent infection.
Bookimed Expert Insight: South Korean centers like Sejong Hospital emphasize lifetime transition care. Our data shows specialists like Dr. Sungho Kim have over 40 years of experience. They specifically monitor patients from childhood into adulthood to manage rare late-developing arrhythmias. This long-term continuity is a hallmark of Korean cardiac protocols.
Patient Consensus: Patients note that heart palpitations or fatigue may linger briefly during the recovery weeks. Most emphasize that attending every scheduled echo check is vital for catching minor residual flows early.
International patients typically stay in South Korea for 5 to 14 days for atrial septal defect (ASD) treatment. Minimally invasive catheter-based closures require shorter stays of 3 to 7 days. Open-heart surgery necessitates at least 10 to 14 days for recovery and safe travel clearance.
Bookimed Expert Insight: While large Seoul centers handle massive volumes, Sejong Hospital in Incheon specializes purely in heart health. Dr. Sungho Kim pioneered catheter-based treatments there and has performed over 1,200 procedures. Choosing a heart-specific facility can streamline your pre-op timeline, potentially saving 2 days of diagnostic waiting.
Patient Consensus: Patients note that pre-surgical clearance is often the longest part of the trip. Most recommend booking a return flight with flexible dates to accommodate the doctor's final post-procedure checkup.
Major Korean cardiologists at institutions like Severance Hospital and Sejong Hospital frequently speak fluent English. These specialists often undergo clinical training or research in Western medical centers. Top-tier hospitals also operate dedicated international centers staffed with coordinators to bridge language gaps for atrial septal defect patients.
Bookimed Expert Insight: While doctors often speak English well, the logistics of a 3,700-bed facility like Severance Hospital can be overwhelming. High-volume centers often prioritize English-speaking coordinators for surgical patients, which is critical for complex atrial septal defect treatments. Our data shows hospitals with Global Healthcare Accreditation (GHA) provide more consistent English support across all departments.
Patient Consensus: Patients note that while doctors explain procedures clearly in English, it is helpful to have simple, written questions ready for nursing and administrative staff. Using the hospital international center is essential for navigating consent forms and discharge instructions without confusion.
