Uncommon Anatomy of the Pulmonary Veins (Example 2): the “Roof Pulmonary Vein”


This is a 50-year-old male patient with recurrent episodes of idiopathic paroxysmal atrial fibrillation refractory to medical therapy. During repeated 24-h Holter monitoring, long-lasting episodes of atrial fibrillation (up to 24 h) were initiated by P/T ectopies. He was then referred to our institution for ablation of atrial fibrillation. Transthoracic echo cardiogram showed normal ventricular function and mild dilatation of the left atrium. Transoesophageal echocardiogram showed no intracavitary thrombi.
