Technique of coronary sinus plasty for left pulmonary vein stenosis.
Overview
abstract
We describe a technique of coronary sinus plasty used to treat an infant with compression of the left pulmonary vein between the descending aorta and a dilated coronary sinus related to a persistent vena cava. The left lower pulmonary vein stenosis was relieved by repositioning the floor of the coronary sinus more anteriorly, toward the mitral annulus. The potential role played by a persistent left superior vena cava in some cases of left pulmonary vein stenosis is discussed.
