This chapter discusses echocardiographic evaluation of tricuspid and pulmonic valve. Echocardiography has historically and clinically been shown to provide unique information about cardiac anatomy, physiology, hemodynamic and blood flow and is a noninvasive monitor with a relative ease in performance. This chapter focuses on transesophageal probe placement, recommended cross-sectional views, flow patterns, quantitative equations including the clinical approach to the noninvasive quantification of both stenotic and regurgitant lesions of the tricuspid and pulmonic valve (PV). Proper PV function requires normal leaflet anatomy and support from the pulmonary artery and RV outflow tract (RVOT). Different views of transesophageal echo examination of the tricuspid valve are discussed. Abnormalities of the tricuspid valve are described. Tricuspid stenosis, pulmonary regurgitation, pulmonary stenosis, grading pulmonic stenosis, and historical aspects of echocardiography of tricuspid and pulmonary valve are explained.
