Abstract

Background: Tricuspid valve or right atrio-ventricular valve is present in human heart between right atrium and ventricles. It prevents back flow of blood from ventricle to atrium during systole. The Tricuspid valve is more complex than the mitral valve, because of its high variability. Traditionally it is described as containing three leaflets (anterior, posterior and septal), the chordae tendinae, two discrete papillary muscles and the fibrous Tricuspid annulus. Gross morphology of Tricuspid valve complex is more important parameter to know during surgical intervention of valve complex. Errors during valve surgeries commonly result in failure of valvular graft, valve prolapse and improper correction.
Methodology: The study was taken on 96 adult human heart specimens, collected from the Department of Anatomy and Forensic Medicine, at Patna medical college and Hospital Patna. Study duration of three years.  The specimens obtained were fixed in 10% formalin and were finely dissected.
Conclusion: The present study adds up to the existing knowledge regarding anatomy and variations in Tricuspid valve complex. Knowledge regarding the normal anatomy and variations of the Tricuspid valve complex is highly esteemed and it is considered a prerequisite for the entire clinical workflow including diagnosis, therapy-planning, surgery, or percutaneous interventions as well as patient monitoring and follow-up.
