Transcatheter coil embolization for coronary and pulmonary arteriovenous malformations

C oronary artery fistulas (CAFs) and pulmonary arteriovenous malformations (PAVMs) are relatively rare but clinically important cardiovascular abnormalities that may require percutaneous treatment. In most patients, the current preferred treatment for both lesions is transcatheter embolization using techniques that are well established in these two conditions. We present a review of CAF and PAVM treatment with emphasis on the technical aspects of transcatheter embolization.
