Makers of devices for ablation for atrial fibrillation (AF) have struggled at times to overcome clinician skepticism, but a new report in a respected medical journal might persuade some of those cardiologists. A study of nearly 28,000 AF patients in South Korea demonstrated that device therapy yielded lower rates of death and admission for heart failure compared to medical therapy, suggesting that ablation is a valid alternative to medical therapy, at least for patients in Asia.
