Background: Valvular heart diseases are one of the most common pathologies of heart. Modalities of treatment available for valvular disease are balloon valvuloplasty, valvotomy and replacement by prosthetic valve. Hence the morphometry of tricuspid valve is important. Materials and methods : For this study we dissected 120 formalin fixed hearts and studied tricuspid valvular complex. We found that there were a lot of variations in the number and dimensions of cusps in tricuspid valve. Results: Normal tricuspid valve with three cusps was found only in 51.66% of hearts. Bicuspid, tricuspid valve was present in seven hearts. The number of accessory cusps ranged from one to four. Most of the anterior cusp, posterior cusp and septal cusp was found to be triangular in shape. The anterior cusp was found to be largest in length, followed by septal cusp. The average height of all anterior, posterior and septal cusps was almost same. Conclusion: This data will be of immense value to cardiothoracic surgeons and also for manufacture of modern type of prosthesis of tricuspid valve.Downloads
