Association of coronary to left ventricular microfistulae (vessels of Wearn) with atrial septal defect in an adult without cyanotic heart disease.

Vessels of Wearn are rare findings during coronary angiography in adults. They are known to be associated with forms of cyanotic congenital heart disease in infants but we are not aware of any published cases of association with non-cyanotic left to right shunts in adults. We present the case of a 69-year-old man with angiographically evident vessels of Wearn draining from the left and right coronary arteries into the left ventricle associated with an asymptomatic atrial septal defect.

Lesion complexity and angiographic outcomes in radial access percutaneous coronary intervention.

Background: Percutaneous coronary intervention (PCI) is increasingly performed from the radial arterial (RA) access site. Few studies have examined the interaction between a default radial approach, lesion complexity, and angiographic outcome. This study investigates lesion complexity, arterial access route, and angiographic outcome in routine clinical practice by default radial operators.
