Pulmonic valve endocarditis as an underdiagnosed disease: role of transesophageal echocardiography

J Am Soc Echocardiogr. 1992 Jan-Feb;5(1):48-51. doi: 10.1016/s0894-7317(14)80102-8.


Pulmonic valve endocarditis is a rare clinical entity. In spite of an increase in the frequency of right-sided endocarditis, primarily it is the tricuspid valve that is involved. Two-dimensional transthoracic echocardiography has improved our ability to diagnose infective endocarditis but has not identified many cases of pulmonic valve endocarditis. With the use of transesophageal echocardiography, three recent cases of pulmonic valve endocarditis were diagnosed by our laboratory. Each of these patients had clinical evidence of right-sided endocarditis, yet routine transthoracic echocardiograms failed to identify any pulmonic valve abnormalities. The true incidence of pulmonic valve endocarditis may be higher than previously reported, and the transesophageal echocardiogram is the preferred method for identifying and evaluating pulmonic valve endocarditis in adults.
