Description
Shuang Zhang and colleagues reported in 2024 a case where a rare extra vein, a persistent left superior vena cava, proved to be the trigger for a patient's atrial fibrillation. This vessel is a birth variant found in a small share of people. It is usually silent, but heart muscle sleeves inside it can fire off abnormal beats.
The patient had persistent atrial fibrillation. A first freezing ablation helped the heart, but the rhythm later returned, and a second, heat-based procedure traced the trigger to the extra vein. Isolating that vein stopped the fibrillation, and no arrhythmia came back over more than six months of follow-up. The case shows a hidden trigger worth seeking.
