A 70-year-old woman with intractable angina pectoris undergoes cardiac catheterization for possible mechanical intervention. She prefers PTCA to open correction. The following is/are true:
A. A long symmetric lesion in the left main coronary artery would be appropriate for PTCA
B. Multiple obstructive lesions in the same artery would be a contraindication to PTCA
C. A focal lesion in the left anterior descending coronary artery where the vessel is 1 mm in diameter would allow PTCA
D. Successful PTCA for a simple lesion carries a recurrent stenosis risk of less than 10%
Answer:B
