Percutaneous closure of coronary fistulas in adults using microvascular plugs

Percutaneous closure of coronary fistulas can be a challenge, given the tortuosity and the small caliber of the anomalous vessel. The microvascular plugs (MVP) are polytetrafluoroethylene-coated nitinol devices designed to perform embolization of small peripheral vessels. Its reduced profile allows the release of the device through microcatheters, facilitating the intervention. We present three cases of coronary fistulas in adults, percutaneously closed through radial access using these devices.
