Isolated bilateral ostial coronary stenosis with proximal right coronary artery occlusion

The incidence of coronary ostial stenosis in patients undergoing coronary arteriography has been found to range between 0.07 and 0.25%. A slightly higher incidence has been observed in patients with angiographically confirmed coronary artery disease: between 0.13 and 2.7%. Bilateral ostial stenosis is even less common. Although cardiovascular syphilis is no longer a prominent condition, it must be considered in the differential diagnosis since it carries a very high risk (50%) of cardiovascular complications if left untreated. Ostial coronary stenosis occurs in 26% of patients with syphilitic aortitis. This paper reports on a 41-year-old Wasserman (WR)- positive woman with progressive angina caused by bilateral ostial coronary stenosis.
