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 aortic stenosis by modifying the Brom aortoplasty. An autologous pericardial patch was used to enlarge the left main coronary artery as well as the stenotic aorta. This modification allows simple and effective restoration of coronary blood flow, while maintaining the Brom procedure's merit of achieving anatomic geometry of the aortic root in such patients.
