Not every atrial septal defect requires closure. Small defects under 6 mm often close spontaneously in children. Even if they don’t, they cause no heart strain. Surgeons recommend intervention if the defect causes right-sided heart enlargement. They also act if it triggers symptoms like shortness of breath. They intervene if it increases stroke and arrhythmia risks.
Bookimed Expert Insight: South Korean cardiac centres excel in avoiding open-heart surgery through catheter-based interventions. Prof. Sungho Kim at Sejong Hospital has performed over 1,200 such procedures. This high volume lets specialists treat complex congenital cases. It also reduces recovery time compared to traditional chest surgery.
Patient Consensus: Patients note that very small holes in infants are usually rechecked later. They are not treated immediately. Many emphasise that catheter-based repair in Republic of Korea is highly effective. It is also minimally invasive.
Recovery from atrial septal defect treatment in the Republic of Korea varies. It depends on the procedure type. Catheter-based closures typically require 2 to 4 days in hospital. Surgical repairs usually involve 3 to 5 days in hospital. Patients generally return to normal activities within 1 to 8 weeks.
Bookimed Expert Insight: Leading Korean centres include Severance Hospital and Seoul National University Bundang Hospital. They treat over 3 million outpatients annually. High volume allows specialists like Prof. Sungho Kim to perform 1,200+ procedures. This depth of experience often enables discharge within 10 days, even for complex surgical cases.
Patient Consensus: Patients note they feel pain-free within a week in South Korea. Flutters or chest heaviness can persist for 1 month while the heart settles. Early recovery feels fast. However, doctors explain full internal healing takes 6 to 12 months.
Follow-up care in South Korea involves routine cardiology check-ups at 1 day, 1 month, 6 months, and 1 year. Specialists use echocardiograms and ECGs to confirm device stability. Care includes antiplatelet medication for 6 months and activity restrictions so the heart heals correctly.
Bookimed Expert Insight: South Korean specialists like Dr Sungho Kim at Sejong Hospital focus on catheter-based closure to avoid open-heart surgery. Data shows centres like Severance Hospital report lower arrhythmia risks with these minimally invasive methods compared to surgical repair. This makes long-term follow-up smoother, as patients experience fewer post-operative rhythm complications.
Patient Consensus: Patients note overnight hospital observation is common. Heart palpitations may occur during the first month. Recovery often involves a gradual return to exercise, with specific warnings to avoid caffeine if fluttering sensations increase.
