Uncommon Anatomy of the Pulmonary Veins (Example 1): Common Trunk of the Inferior Pulmonary Veins
This a 66-year-old male patient with recurrent paroxysmal atrial fibrillation associated with hypertension, which was treated with beta-blockers. Previously, he underwent percutaneous revascularisation for angina pectoris. Over the last six months, the patient had complained of palpitations, which were documented by Holter monitoring as atrial fibrillation with fast ventricular response and initiated by left atrial ectopies. Transthoracic echocardiography showed a normal left ventricle with preserved systolic function and mild septal hypertrophy; the atria were normally sized and there were no signs of pulmonary hypertension. The chest X-ray was also normal. The patient never complained of dyspnea, either at rest or during effort. Since atrial fibrillation was not responsive to antiarrhythmic drug therapy, electrical isolation of the pulmonary vein was planned. In addition, a contrast-enhanced multi-slice computed tomography scan of the heart was performed with the patient in sinus rhythm.
