Transcatheter aortic valve implantation (TAVI) in Republic of Korea: Our Best Clinics and Costs 2026

Korean National Health Insurance (NHI) covers Transcatheter Aortic Valve Implantation (TAVI) for severe symptomatic aortic stenosis. Coverage levels depend on patient age and surgical risk. High-risk patients aged 80 or older receive 95% coverage, while medium and low-risk patients face higher co-payments.

• Co-payment rates: Patients aged 80+ or high-risk pay 5%; medium-risk 50%; low-risk 80%.
• Eligibility criteria: Requires Health Insurance Review and Assessment Service (HIRA) approval and specific risk scores.
• Facility requirements: Procedures must occur at HIRA-certified centers like Asan Medical Center or Severance Hospital.
• Exclusion factors: Patients with life expectancy under 1 year or needing other major surgeries are ineligible.

Bookimed Expert Insight: Seoul-based university hospitals like Samsung Medical Center and Asan Medical Center dominate TAVI volume. Asan alone performs 45% of Korea's heart transplants. Patients should prioritize these JCI-accredited facilities in Seoul, as regional centers often lack the specialized multidisciplinary teams required for HIRA insurance approval.

Patient Consensus: Patients emphasize securing HIRA pre-authorization weeks in advance to avoid surprise bills. Many report long waitlists of 3–6 months at top-tier Seoul hospitals for insurance-covered slots.

The success rate for TAVI in South Korea ranges from 99% to 99.7% for immediate procedural outcomes. Top-tier medical centers in Seoul, such as Asan Medical Center and Seoul St. Mary’s Hospital, report success exceeding 99% across thousands of clinical cases.

• Procedural success: High-volume centers achieved a 99.7% success rate in a 3,463-patient study.
• Survival rate: The 30-day survival at specialized Seoul institutions is approximately 97.4%.
• Stroke incidence: Severe stroke risk remains low, typically occurring in 1.2% to 1.9% of cases.
• Five-year survival: Long-term data shows survival rates between 80.5% and 87% after five years.

Bookimed Expert Insight: While many countries offer TAVI, South Korean centers like Asan Medical Center perform 45% of the nation's heart transplants. This extreme surgical volume directly correlates with their 99.7% TAVI success rate. Patients should prioritize clinics performing at least 100 TAVI cases annually for the best results.

Patient Consensus: Patients report that outcomes depend heavily on the integrated heart team approach. Many feel reassured by the 10-year valve longevity data now available from experienced Korean teaching hospitals.

TAVI risks in Korea are notably low due to high clinical experience at centers like Samsung Medical Center and Asan Medical Center. Primary complications include permanent pacemaker implantation in 5.6% to 8.0% of patients and vascular access issues such as hematomas or dissections in 6.27% of cases.

• Conduction disturbances: Permanent pacemaker implantation occurs in 5.6% to 8.0% of Korean patients.
• Paravalvular leakage: Moderate or severe leaks occur in 6.0% of cases, requiring careful monitoring.
• Vascular complications: Access site issues like femoral artery damage affect approximately 6.27% of patients.
• Stroke incidence: In-hospital stroke rates remain low in Korea at 1.1% to 1.2% currently.
• Major bleeding: Recent data shows bleeding rates decreased from 5.7% to 1.5% recently.

Bookimed Expert Insight: Korea’s top hospitals demonstrate a clear experience curve benefit. Asan Medical Center alone performs 45% of South Korea's heart transplants. This high volume across major Seoul clinics has directly reduced major bleeding rates by nearly 75% over the last decade. Patients should prioritize clinics with KOIHA accreditation to ensure these international safety standards.

Patient Consensus: Many patients describe paravalvular leaks as a frustrating complication requiring long-term follow-up. Most advice emphasizes discussing the 10-20% pacemaker risk with surgeons before the procedure.

In South Korea, TAVI patients typically stay in the hospital for 2 to 5 days, while specific high-volume centers in Seoul often discharge low-risk patients within 24 to 72 hours. Initial recovery involves immediate bed rest followed by light activity within 1 to 2 weeks.

• Hospital stay: Most patients discharge within 3 days at centers like Severance Hospital.
• ICU monitoring: Expect 24 to 48 hours for vital sign and access site observation.
• Bed rest: Patients remain horizontal for 6 to 10 hours to prevent site bleeding.
• Full recovery: Energy levels improve quickly, with a full heart adjustment by 3 months.
• Frail patients: Extended stays of 5 to 10 days occur for complex medical cases.

Bookimed Expert Insight: Korea's massive patient volumes significantly impact safety. Asan Medical Center performs 45% of all heart transplants in South Korea. Their expertise in complex cardiac surgery ensures TAVI complications remain low. High-volume centers often achieve next-day discharge for low-risk patients.

Patient Consensus: Many patients report walking the same day of the procedure. While physical incisions are minimal, some feel a surge of fatigue during the second week of recovery.

Asan Medical Center, Samsung Medical Center, and Severance Hospital are the premier choices for TAVI in South Korea. These centers lead Asia in procedure volume, with Asan Medical Center maintaining a 99.7% success rate and performing over 300 annual cases using advanced heart valve replacement techniques.

• Asan Medical Center: Over 2,000 cases completed with designation as Asia's only TAVI Teaching Center.
• Samsung Medical Center: Pioneer of TAVI in Korea using multidisciplinary teams and robotic-assisted valve repair.
• Severance Hospital: First JCI-accredited facility in Korea offering fast-track cardiac services for international patients.
• Seoul National University: Top-tier state facility treating 10,700 patients daily with fully digitalized cardiac systems.

Bookimed Expert Insight: Data shows a clear distinction between these `Big 5` hospitals and smaller clinics regarding TAVI experience. While many hospitals offer cardiac care, only Asan and Severance consistently exceed 200–300 cases annually. This high volume is the most reliable predictor of safety, as it ensures the entire surgical team remains specialized in the latest transcatheter deployment techniques.

Patient Consensus: Patients emphasize that while waitlists can be long, the coordination for international arrivals is seamless. Many highlight the rapid 3-day discharge and the significant cost difference compared to US-based treatment.
