Surgical angioplasty of left main coronary stenosis complicating supravalvular aortic stenosis

We successfully treated obstruction of the main coronary artery, not aortic valve leaflet adhesion to the intimal shelf, complicating supravalvular ao rtic stenosis by modifying the Brom aortoplasty. An autologous pericardial patch was used to enlarge the left main coronary artery as well as the sten otic aorta. This modification allows simple and effective restoration of co ronary blood flow, while maintaining the Brom procedure's merit of achievin g anatomic geometry of the aortic root in such patients.
