jet lesions

(redirected from Zahn-Schmincke Pockets)
Vegetations that develop where a regurgitant ‘jet’ of turbulent blood flow strikes the endocardium, causing fibrosis and roughening, typical of anomalies of blood flow from a high-to-low pressure region—e.g., aortic stenosis or coarctation, mitral stenosis, ventricular septal defect, or patent ductus arteriosus, as occurs in rheumatic fever or congenital heart disease; roughened JLs may give rise to small emboli and produce cerebral thromboembolism
