Percutaneous closure of coronary artery fistulae: is it time for a UK registry?

Most coronary artery fistulae are asymptomatic but there may be complications such as rupture and myocardial infarction. Percutaneous intervention is an attractive alternative to open surgical repair that offers lower procedural risk.
Increasing numbers of fistulae are being discovered incidentally during angiography. They present challenges in assessment and management. For example, there is poor correlation between symptoms and the size and flow rate of fistulae.
