Pulmonary Arteriovenous Malformation Associated with Atrial Fibrillation Which Needed Oral Anticoagulants

Pulmonary arteriovenous malformation (PAVM) represents an abnormal communication between the pulmonary arteries and veins. Symptoms occur slowly with the increasing size of PAVM and they are represented by dyspnea, epistaxis and hemoptysis, which, sometimes, can be severe leading to the death of the patient. On the other hand, atrial fibrillation is the most common sustained cardiac arrhythmia and oral anticoagulants (OAC) represent an efficient treatment in stroke prevention. In this paper we discuss a case of PAVM clinically manifested with massive hemoptysis, and which associated atrial fibrillation that needed oral anticoagulation.
