Abstract
A new technique of pulmonary vein wedge angiography to delineate pulmonary artery anatomy is described. Conventional pulmonary vein wedge angiography requires an interatrial communication--natural or created by a transseptal puncture. In retrograde pulmonary vein wedge angiography, the left atrium and pulmonary veins are entered from arterial route using a specially designed catheter. This technique can be specially utilized for patients in whom there is no interatrial communication.
