Superior vena cava is one of the important AF triggers. Superior vena cava bigeminy acts as a trigger of AF. Attention should be paid to the bigeminal activities of the thoracic veins in AF catheter ablation.

Background
The very high-power short-duration (vHPSD) temperature-controlled ablation (vHPSD) improves the efficiency of pulmonary vein isolation (PVI) procedures.
We evaluated the procedural and 12-months outcomes in atrial fibrillation (AF) patients undergoing PVI by means of vHPSD ablation. In patients with AF or atrial tachyarrythmia (AT) recur...
Atrial fibrillation (AF), the most common cardiac arrhythmia is associated with increased morbidity and mortality. The higher mortality is due to the risk of heart failure and cardioembolic events. This in-depth review focuses on the strategies and efficacy of catheter ablation for non-paroxysmal atrial fibrillation. The main medical databases were...
Currently, pulmonary vein isolation (PVI) is the gold standard in catheter ablation for atrial fibrillation (AF). However, PVI alone may be insufficient in the management of persistent AF, and complementary methods are being explored. One such method takes an anatomical approach—improving both its success rate and lesion durability may lead to impr...
Pulmonary vein ablation has become a key treatment for atrial fibrillation (AF). However, recurrences can occur. The ideal strategy for ablation after AF recurrence is controversial, complex, and challenging, with limited data available. By presenting a series of cases, we summarize and discuss key elements in the understanding and treatment of pat...
