Sources: 6. Developments: 2. Severance Cardiovascular Hospital has demonstrated significant advancements in cardiology through both academic research and clinical practice. Between November 2023 and August 2024, the hospital’s Department of Cardiology published four research papers in the New England Journal of Medicine (NEJM). These studies addressed critical topics such as anticoagulation therapy for atrial fibrillation patients, the effectiveness of lowering LDL cholesterol targets, and the necessity of dual antiplatelet therapy for high-ischemic-risk patients. In addition to these research achievements, the hospital reached a clinical milestone by completing 10,000 cumulative atrial fibrillation procedures. This total includes 7,546 radiofrequency ablation cases, 1,271 pulsed field ablation (PFA) cases, and 1,183 cryoballoon ablation cases. The institution has been a leader in adopting new technologies like PFA and serves as an international training center for the procedure. ## Timeline ### 2026-10-02: Severance Cardiovascular Hospital reaches 10,000 atrial fibrillation procedures Severance Cardiovascular Hospital has achieved a South Korean record by completing 10,000 atrial fibrillation procedures, utilizing advanced techniques like pulsed field ablation. 4 sources. https://clstr.news/cluster/severance-cardiovascular-hospital-reaches-10000-atrial-fibrillation-procedures ### 2026-09-30: Severance Cardiovascular Hospital publishes four papers in NEJM Severance Cardiovascular Hospital cardiology faculty published four research papers in the New England Journal of Medicine within nine months, covering topics like atrial fibrillation and cholesterol targets. 4 sources. https://clstr.news/cluster/severance-cardiovascular-hospital-publishes-four-papers-in-nejm --- Cite as: Severance Cardiovascular Hospital cardiology advancements.
