Angina pectoris after aortic valve replacement

Abstract

Angina pectoris after aortic valve replacement may be due to reduced myocardial blood flow (coronary artery stenosis or valvular dysfunction) or to increased myocardial oxygen demand (idiopathic hypertrophic subaortic stenosis or valvular dysfunction). If a patient does not do well after an aortic valve replacement, causes other than dysfunction of the prosthesis should be sought.
